## Overview
**LibreDB Studio** is a lightweight, high-performance, and secure web-based SQL editor designed to bridge the gap between heavy desktop applications (like DataGrip/DBeaver) and minimal CLI tools. Built with a "Mobile-First, Professional-Always" philosophy, it empowers engineering teams to manage databases anywhere—from a 4K monitor to a mobile screen.
### Why LibreDB Studio?
- **Zero Install**: Run a professional SQL IDE in your browser or private network.
- **Multi-Platform**: Native-like experience on both **Web** and **Mobile** browsers.
- **AI-Native**: Multi-model support (Gemini, OpenAI, or Local LLMs) for NL2SQL.
- **DevOps Ready**: Optimized for Kubernetes orchestration and Docker environments.
- **Enterprise Grade**: Built-in RBAC, SSO (OIDC), query auditing, and live health monitoring.
Connect to PostgreSQL, MySQL, Oracle, SQL Server, MongoDB, Redis, or SQLite with SSL/TLS and SSH Tunnel support.

## Key Features
### Professional SQL IDE
- **Monaco Engine**: Powered by the same core as VS Code.
- **Smart Autocomplete**: Schema-aware suggestions for tables, columns, and SQL keywords.
- **Multi-Tab Workspace**: Handle parallel tasks with independent execution states.
- **Visual EXPLAIN**: Graphical execution plans to identify performance bottlenecks.
- **Interactive ER Diagrams**: Visual schema graph with real foreign key edges, cardinality labels, MiniMap navigation, table search/filter, compact mode, and PNG/SVG export. Automatic hierarchical layout powered by ELK.js.
- **Schema Diff & Migration**: Compare schema snapshots or cross-connection schemas side-by-side. Color-coded diff view (added/removed/modified) with automatic migration SQL generation for PostgreSQL, MySQL, SQLite, Oracle, and SQL Server.
- **Snapshot Timeline**: Visual horizontal timeline of schema snapshots. Click any two points to instantly compare and track schema evolution over time.
Visual schema explorer with interactive ER diagrams powered by ReactFlow.
### Multi-Model AI Copilot
- **Universal LLM Support**: Defaults to Gemini 2.5 Flash, but ready for OpenAI, Claude, or **Local LLMs** (Ollama/LM Studio).
- **NL2SQL**: Generate complex queries from natural language with schema-aware context.
- **Query Safety Analysis**: AI-powered pre-execution risk assessment for destructive queries (DELETE, DROP, TRUNCATE).
- **AI Query Explainer**: EXPLAIN plans translated into plain language with optimization suggestions.
- **AI Query Autopilot**: Automated slow query analysis with actionable index and rewrite recommendations.
- **Schema Awareness**: AI understands your specific database structure for pinpoint accuracy.
- **Plug & Play**: Works out of the box with zero complex configuration.
Ask questions in plain English and get executable SQL queries instantly.
### Pro Data Management
- **Universal Data Grid**: Virtualized rendering (TanStack) for millions of rows.
- **Inline Editing**: Double-click to update values directly in the grid.
- **Column Filtering**: Per-column text filters on query results for instant data exploration.
- **Interactive Pivot Table**: Client-side pivoting with 5 aggregation functions (COUNT, SUM, AVG, MIN, MAX) and SQL generation.
- **Expert Exporter**: Instant CSV and JSON exports for reporting.
### Advanced Data Visualization
- **8 Chart Types**: Bar, Line, Pie, Area, Scatter, Histogram, Stacked Bar, and Stacked Area charts powered by Recharts.
- **Data Aggregation**: Group-by with SUM, AVG, COUNT, MIN, MAX aggregation functions. Date grouping by hour, day, week, month, or year.
- **Chart Persistence**: Save chart configurations and reload them instantly. Manage a library of saved charts.
- **Chart Dashboard**: Grid view of all saved charts for at-a-glance data overview directly in the bottom panel.
### Display Masking (Preview)
- **Client-Side Display Layer**: Masks sensitive values in the browser UI — useful for screen sharing, demos, and reducing accidental on-screen exposure. **Not server-enforced**; query API responses still contain full values for authenticated users.
- **Column-Name Pattern Matching**: 10 built-in patterns (email, phone, credit card, SSN, password, IP, date, financial, and more) match **result column headers** by regex. Works when the output name matches (e.g. `SELECT salary`). Aliases (`salary AS x`) and aggregates (`SUM(salary)`) are not masked today.
- **Configurable Rules**: Admin panel to add, edit, enable/disable masking patterns. Custom patterns with regex support. Settings stored per-browser in localStorage.
- **RBAC UI Controls**: User role cannot toggle or reveal masked cells in the UI. Admin role can toggle masking and temporarily reveal individual cells (10s auto-hide).
- **Export & Clipboard**: CSV, JSON, and SQL INSERT exports use masked display values when masking is active in the UI. This does not prevent access to raw data via the API, browser DevTools, or admin reveal.
- **UI Coverage**: Grid, mobile card/table views, row detail sheet, and clipboard copy respect the active display mask.
### Analyst & Developer Tools
- **AI Data Profiler**: One-click table profiling with column statistics (null %, cardinality, min/max, sample values) and AI-powered narrative summaries.
- **ORM Code Generator**: Generate TypeScript interfaces, Zod schemas, Prisma models, Go structs, Python dataclasses, and Java POJOs from live table schemas.
- **Test Data Generator**: Schema-aware fake data generation with 30+ semantic column inferences (email, phone, name, address, etc.). Produces INSERT statements or MongoDB insertMany JSON.
- **Database Documentation**: Auto-generated searchable data dictionary from live schema with AI-powered documentation and Markdown export.
One-click column profiling: null %, cardinality, min/max, and sample values for 300K+ rows.
Generate TypeScript interfaces, Prisma models, Go structs, and more from live schemas.
### Authentication & SSO
- **Dual Auth Modes**: Local email/password login or OpenID Connect (OIDC) Single Sign-On — switchable via environment variable.
- **Vendor-Agnostic OIDC**: Works with any OIDC-compliant provider — Auth0, Keycloak, Okta, Azure AD, Zitadel, Google, and more.
- **PKCE Security**: Authorization Code Flow with Proof Key for Code Exchange (S256) for secure authentication.
- **Auto Role Mapping**: Configurable claim-based role mapping with dot-notation for nested claims (e.g., `realm_access.roles`).
- **Provider Logout**: Logout clears both local JWT session and identity provider session.
### DBA Maintenance Toolkit (Admin Only)
- **Live Monitoring Dashboard**: 7-tab monitoring with Overview, Performance, Queries, Sessions, Tables, Storage, and Connection Pool views.
- **Time-Series Trend Charts**: Real-time metric trends (connections, cache hit ratio, buffer pool, deadlocks) with auto-refreshing ring buffer history.
- **Configurable Auto-Refresh**: Polling intervals from 5s to 60s with play/pause control.
- **Threshold Alerting**: Color-coded health indicators (healthy/warning/critical) for cache hit ratio, connection usage, deadlocks, and buffer pool utilization.
- **Connection Pool Stats**: Live total/active/idle/waiting pool metrics with utilization progress bars.
- **One-Click Maintenance**: Trigger `VACUUM`, `ANALYZE`, `REINDEX`, `UPDATE STATISTICS`, `DBCC CHECKDB`, and `ALTER INDEX REBUILD` per database engine.
- **Audit Trail**: Full history of every query executed across the organization.

## Getting Started
### Install
| Channel | Command | Notes |
| :--- | :--- | :--- |
| **Docker** | `docker run -d -p 3000:3000 ghcr.io/libredb/libredb-studio:latest` | Zero-config: the admin password is printed to the log on first run |
| **Helm (Kubernetes)** | `helm install libredb oci://ghcr.io/libredb/charts/libredb-studio` | Zero-config: first-run admin credentials are printed to the pod log |
| **npx** | `npx @libredb/studio` | Linux/macOS, Node 20.9+ (Node 24 LTS recommended); downloads the release server tarball |
| **Homebrew** | `brew trust libredb/tap && brew install libredb/tap/libredb-studio` | `brew trust` is required once (Homebrew 6+; run `brew update` if unknown) |
| **deb / rpm** | `sudo dpkg -i libredb-studio__amd64.deb` | Attached to each GitHub release; systemd service included |
| **Snap** | `sudo snap install libredb-studio` | From the next release, once Snap Store publishing goes live |
> Homebrew, deb/rpm, Snap, and the npx launcher consume standalone artifacts attached to each GitHub release. Full per-channel guide — commands, configuration, systemd usage, and the Docker image tag model — in [`docs/DISTRIBUTION.md`](docs/DISTRIBUTION.md).
### Quick Start (Docker)
Run LibreDB Studio with a single command — no clone, no install, no build:
```bash
docker run -d \
--name libredb-studio \
-p 3000:3000 \
-e ADMIN_EMAIL=admin@libredb.org \
-e ADMIN_PASSWORD=LibreDB.2026 \
-e USER_EMAIL=user@libredb.org \
-e USER_PASSWORD=LibreDB.2026 \
-e JWT_SECRET=change-me-to-a-random-32-char-string \
ghcr.io/libredb/libredb-studio:latest
```
> **Registry**: `ghcr.io/libredb/libredb-studio` is the primary image (no pull rate limits — preferred for Kubernetes/CI). The same image is also mirrored to Docker Hub as [`libredb/libredb-studio`](https://hub.docker.com/r/libredb/libredb-studio) for convenience.
Open [http://localhost:3000](http://localhost:3000) and login with `admin@libredb.org` / `LibreDB.2026`.
> **Auth env vars (local provider):** `ADMIN_PASSWORD` and `JWT_SECRET` are only required when `AUTH_BOOTSTRAP=off`; otherwise both are generated on first start (see [Zero-config first run](#zero-config-first-run) below). `USER_EMAIL` / `USER_PASSWORD` are optional; omit them to run admin-only (no default user password is ever assumed). `ADMIN_EMAIL` defaults to `admin@libredb.org`. Using OIDC (`NEXT_PUBLIC_AUTH_PROVIDER=oidc`)? None of these are needed.
> **Tip**: Add `-e LLM_PROVIDER=gemini -e LLM_API_KEY=your_key -e LLM_MODEL=gemini-2.5-flash` to enable AI features.
### Zero-config first run
Starting the server without `JWT_SECRET` / `ADMIN_PASSWORD` works out of the box:
the missing values are generated on first start, stored in `/auth-bootstrap.json`
(file mode 0600), and the admin password is printed once to the server log. Explicitly
set environment variables always take precedence. Set `AUTH_BOOTSTRAP=off` to require
explicit configuration instead (recommended for production deployments).
### Linux packages (.deb / .rpm)
Native packages for Debian/Ubuntu and RHEL/Fedora (amd64 and arm64) are attached to every
[GitHub release](https://github.com/libredb/libredb-studio/releases). They bundle the standalone
server together with a private Node.js runtime (nothing else to install) and register a systemd service:
```bash
# Debian / Ubuntu
sudo dpkg -i libredb-studio__amd64.deb
# RHEL / Fedora / Rocky
sudo rpm -i libredb-studio-.x86_64.rpm
# Start the service (first run prints the generated admin password to the journal)
sudo systemctl enable --now libredb-studio
journalctl -u libredb-studio
```
Configuration lives in `/etc/libredb-studio/env` (loaded by the unit; see the commented template
installed there), state (SQLite storage and generated credentials) in `/var/lib/libredb-studio`.
The `libredb-studio` command can also be run directly without systemd. Full details for this and
every other channel: [`docs/DISTRIBUTION.md`](docs/DISTRIBUTION.md).
### Prerequisites
- [Bun](https://bun.sh/) (Recommended) or Node.js 24+
- A target database to query (PostgreSQL, MySQL, Oracle, SQL Server, SQLite, MongoDB, or Redis)
### Quick Start (Local)
1. **Clone & Install**
```bash
git clone https://github.com/libredb/libredb-studio.git
cd libredb-studio
bun install
```
2. **Configure Environment**
Create a `.env.local` file:
```env
# Authentication (email/password)
ADMIN_EMAIL=admin@libredb.org
ADMIN_PASSWORD=your_admin_password
USER_EMAIL=user@libredb.org
USER_PASSWORD=your_user_password
JWT_SECRET=your_32_character_random_string
# Optional: OIDC Single Sign-On (Auth0, Keycloak, Okta, Azure AD, etc.)
# NEXT_PUBLIC_AUTH_PROVIDER=oidc
# OIDC_ISSUER=https://your-provider.com
# OIDC_CLIENT_ID=your_client_id
# OIDC_CLIENT_SECRET=your_client_secret
# LLM Configuration

LLM_API_KEY=your_api_key
LLM_MODEL=gemini-2.5-flash
LLM_API_URL=http://localhost:11434/v1 # optional for local LLMs (Ollama)
```
3. **Launch**
```bash
bun dev
```
Open [http://localhost:3000](http://localhost:3000)

## Development Databases
Need databases to test with? We provide ready-to-use containers for all supported engines:
```bash
# Start all development databases (PostgreSQL, MySQL, MongoDB, SQL Server, Oracle)
docker compose -f database-compose.yml up -d
# Or start a specific database
docker compose -f database-compose.yml up -d postgres
docker compose -f database-compose.yml up -d mssql
docker compose -f database-compose.yml up -d oracle
# Start PostgreSQL with sample e-commerce data
docker compose -f docker/postgres.yml up -d
# Stop (keeps data)
docker compose -f database-compose.yml down
# Stop and remove all data
docker compose -f database-compose.yml down -v
```
### Connection Details
| Database | Host | Port | User | Password | Database/Service |
|----------|------|------|------|----------|-----------------|
| **PostgreSQL** | localhost | 5432 | postgres | postgres | postgres |
| **MySQL** | localhost | 3306 | root | root | mysql |
| **SQL Server** | localhost | 1433 | sa | Password123! | master |
| **Oracle** | localhost | 1521 | system | Password123! | freepdb1 |
| **MongoDB** | localhost | 27017 | admin | admin | — |
### PostgreSQL Sample Data
The `docker/postgres.yml` setup includes a pre-loaded e-commerce schema:
| Feature | Description |
|---------|-------------|
| **PostgreSQL 18** | Official image with `pg_stat_statements` |
| **pg_stat_statements** | Pre-enabled for query monitoring |
| **Sample Schema** | E-commerce database (app schema) |
| **Sample Data** | 25 customers, 30 products, 100 orders |
| **Views** | Order summary, product sales, customer LTV |
Sample tables: `app.customers`, `app.products`, `app.orders`, `app.order_items`, `app.product_reviews`, `app.categories`, `app.coupons`, `app.audit_log`
> This setup is ideal for testing the **Monitoring Dashboard** features with real `pg_stat_statements` data.
---
## Testing
LibreDB Studio has a comprehensive test suite with **3,000+ unit/integration tests** and **32 E2E tests** across 6 layers, with **90%+ line coverage** measured on SonarCloud.
### Quick Commands
```bash
# Run all tests (unit + API + integration + hooks + components)
bun run test
# Run by layer
bun run test:unit # Pure function tests (1,600+ cases)
bun run test:api # API route handler tests (270+ cases)
bun run test:integration # Database provider tests (340+ cases)
bun run test:hooks # React hook tests (250+ cases)
bun run test:components # Component tests with mock isolation (570+ cases)
# E2E tests (requires build)
bun run test:e2e # Playwright browser tests (32 cases)
# Coverage report (lcov)
bun run test:coverage
```
### Test Architecture
| Layer | Directory | Runner | Tests | What it covers |
|-------|-----------|--------|-------|----------------|
| **Unit** | `tests/unit/` | `bun:test` | ~1,609 | Pure functions: SQL parser, connection strings, data masking, query limiter, schema diff, error classes, DB icons, showcase queries |
| **API** | `tests/api/` | `bun:test` | ~279 | Route handlers: auth, query, transaction, maintenance, AI endpoints, middleware |
| **Integration** | `tests/integration/` | `bun:test` | ~346 | Database providers: PG, MySQL, SQLite, MongoDB, Redis, Oracle, MSSQL|
| **Hooks** | `tests/hooks/` | `bun:test` | ~251 | React hooks: auth, connections, tabs, query execution, transactions, inline editing, AI chat, monitoring |
| **Components** | `tests/components/` | `bun:test` + happy-dom | ~570 | UI components: Studio, Sidebar, QueryEditor, ResultsGrid, Admin Dashboard, Charts, ERD |
| **E2E** | `e2e/` | Playwright | ~32 | Full browser flows: login, connections, query execution, tabs, export, admin |
### Key Details
- **Test runner**: `bun:test` (built-in, Jest-compatible API) with `happy-dom` for DOM environment
- **Component isolation**: Component tests run in 6 isolated groups via `tests/run-components.sh` to prevent `mock.module()` cross-contamination
- **E2E**: Playwright with Chromium, runs against a production build (`bun run build && bun start`)
- **CI**: GitHub Actions runs lint + typecheck + build, unit/integration tests with coverage, E2E tests, and SonarCloud analysis
- **Coverage**: `bun test --coverage` generates lcov reports for SonarCloud integration
> **Important**: Always use `bun run test` instead of bare `bun test`. The test script handles proper isolation between test groups.

> **CapRover:** open your CapRover dashboard → **Apps → One-Click Apps/Databases**, search for **LibreDB Studio**, and deploy.
>
> **Koyeb:** set a strong `JWT_SECRET` and credentials before deploying (Koyeb cannot auto-generate secrets). The button uses `STORAGE_PROVIDER=local` — connection metadata lives in the browser, which suits Koyeb's ephemeral filesystem. For persistence across redeploys, switch to `STORAGE_PROVIDER=postgres` and point `STORAGE_POSTGRES_URL` at a Koyeb managed Postgres or Neon database. See [`deploy/koyeb/`](deploy/koyeb/).
>
> **Cosmos:** install in one click from the [Cosmos](https://cosmos-cloud.io) Marketplace — search for **LibreDB Studio**. Cosmos auto-generates secrets, provisions a persistent SQLite volume, and serves the app behind its SmartShield reverse proxy. See [`deploy/cosmos/`](deploy/cosmos/).

## Deployment (DevOps)
### Koyeb
1. **Fork this repository**
2. **Connect to Koyeb**: [app.koyeb.com](https://app.koyeb.com) → New → Blueprint
3. **Select your forked repo** and Koyeb will auto-detect `koyeb.yaml`
4. **Set Environment Variables** in Koyeb Dashboard:
5. **Deploy!**
### Railway
LibreDB Studio is available as a one-click [Railway](https://railway.com) template.
See [`deploy/railway/`](deploy/railway/) for the template definition, install
instructions, and the publish checklist. The template runs the prebuilt
`ghcr.io/libredb/libredb-studio` image with SQLite persistence on a Railway
volume. Note: Docker-image templates require a manual version bump on each
release (same as CapRover).
### CapRover
LibreDB Studio is published in the official [CapRover One-Click Apps](https://github.com/caprover/one-click-apps/blob/master/public/v4/apps/libredb-studio.yml) catalog:
1. **Open your CapRover dashboard** → **Apps → One-Click Apps/Databases**
2. **Search** for **LibreDB Studio**
3. **Fill in the variables** (admin/user credentials, `JWT_SECRET`, optional AI/storage settings)
4. **Deploy!**
The app runs the prebuilt `ghcr.io/libredb/libredb-studio` image. As with Railway, Docker-image templates require a manual version bump on each release.
### Kubero
LibreDB Studio is listed in the official
[Kubero template catalog](https://www.kubero.dev/templates) (a self-hosted
"Heroku alternative for Kubernetes"). From your Kubero dashboard, browse
**Templates**, search **LibreDB Studio**, fill in the credentials / `JWT_SECRET`,
and deploy. The template runs the prebuilt `ghcr.io/libredb/libredb-studio` image
with SQLite persistence on a 5Gi volume at `/app/data`. See
[`deploy/kubero/`](deploy/kubero/) for install and post-install details. As with
Railway and CapRover, Docker-image templates require a manual version bump on
each release.
### Cosmos
LibreDB Studio is listed in the official
[Cosmos servapp marketplace](https://github.com/azukaar/cosmos-servapps-official)
([Cosmos](https://cosmos-cloud.io) is a self-hosted server manager and secure
reverse proxy). From your Cosmos dashboard, open **Marketplace**, search
**LibreDB Studio**, and install. Cosmos auto-generates the credentials and
`JWT_SECRET`, provisions a persistent SQLite volume at `/app/data`, and serves
the app behind a SmartShield-protected route. See
[`deploy/cosmos/`](deploy/cosmos/) for install and post-install details. As with
Railway, CapRover, and Kubero, Docker-image templates require a manual version
bump on each release.
### Render (Recommended for cloud deployment)
LibreDB Studio includes a `render.yaml` Blueprint for one-click deployment:
1. **Fork this repository**
2. **Connect to Render**: [dashboard.render.com](https://dashboard.render.com) → New → Blueprint
3. **Select your forked repo** and Render will auto-detect `render.yaml`
4. **Set Environment Variables** in Render Dashboard:
5. **Deploy!**
### Docker Compose (Self-Hosted)
Use the ready-to-use [`docker-compose.example.yml`](docker-compose.example.yml) — it pulls the published image (`ghcr.io/libredb/libredb-studio:latest`), so no source build is needed. It documents every supported environment variable (auth, OIDC, storage, LLM, seed connections), with the less-common ones commented out.
```bash
# 1. Copy the ready-to-use compose file
cp docker-compose.example.yml docker-compose.yml
# 2. Create your .env (set at least JWT_SECRET / ADMIN_PASSWORD / USER_PASSWORD)
cp .env.example .env
# 3. Start
docker compose up -d # → http://localhost:3000
```
This file is platform-neutral and works with PaaS tools that consume a plain `docker-compose.yml` (Dokploy, Coolify, Portainer, etc.) — point them at the file and set the secrets as environment variables.
> The repository's default `docker-compose.yml` builds the image from source (`build: .`) and is intended for local development.
### Kubernetes (Helm Chart)
```bash
helm repo add libredb https://libredb.org/libredb-studio/
helm install libredb libredb/libredb-studio
# Retrieve the generated admin credentials from the pod log
kubectl logs deployment/libredb-libredb-studio | grep -A 4 "generated admin credentials"
```
Or via OCI registry:
```bash
helm install libredb oci://ghcr.io/libredb/charts/libredb-studio
```
For production, provide your own secrets instead of relying on generated ones:
```bash
helm install libredb libredb/libredb-studio \
--set secrets.jwtSecret=$(openssl rand -base64 32) \
--set secrets.adminPassword=MyAdmin123
```
Features: PostgreSQL subchart, Ingress/TLS, HPA, PDB, NetworkPolicy, ExternalSecrets support. See [charts/libredb-studio/README.md](charts/libredb-studio/README.md) for full documentation.
### Seed Connections (Pre-Configured Databases)
Pre-configure database connections via a YAML config file so users see them immediately after login. Ideal for Platform/SaaS deployments where admins provision databases for teams.
**Features:**
- Role-based access control (`admin`, `user`, `*` wildcard)
- Hybrid model: `managed: true` (read-only, admin-controlled) or `managed: false` (editable copy for user)
- Credentials injected via `${ENV_VAR}` syntax — never stored in config file
- Hot-reload: config changes apply within 60s without restart
- Works with Docker, docker-compose, and Kubernetes (Helm)
**1. Create a config file** (`seed-connections.yaml`):
```yaml
version: "1"
defaults:
managed: true
environment: production
connections:
- id: "prod-analytics"
name: "Production Analytics"
type: postgres
host: analytics-db.internal
port: 5432
database: analytics
user: "readonly_user"
password: "${ANALYTICS_DB_PASSWORD}"
roles: ["admin"]
color: "#10B981"
- id: "dev-sandbox"
name: "Dev Sandbox"
type: mysql
host: dev-mysql.internal
port: 3306
database: sandbox
user: "dev_user"
password: "${DEV_DB_PASSWORD}"
roles: ["*"]
managed: false
```
**2. Mount and configure:**
Docker
```bash
docker run -v ./seed-connections.yaml:/app/config/seed-connections.yaml:ro \
-e SEED_CONFIG_PATH=/app/config/seed-connections.yaml \
-e ANALYTICS_DB_PASSWORD=secret \
-e DEV_DB_PASSWORD=devsecret \
ghcr.io/libredb/libredb-studio:latest
```
Docker Compose
```yaml
services:
app:
image: ghcr.io/libredb/libredb-studio:latest
volumes:
- ./seed-connections.yaml:/app/config/seed-connections.yaml:ro
environment:
SEED_CONFIG_PATH: /app/config/seed-connections.yaml
ANALYTICS_DB_PASSWORD: ${ANALYTICS_DB_PASSWORD}
DEV_DB_PASSWORD: ${DEV_DB_PASSWORD}
```
Kubernetes (Helm)
```yaml
# values.yaml
seedConnections:
enabled: true
config:
version: "1"
connections:
- id: "prod-analytics"
name: "Production Analytics"
type: postgres
host: analytics-db.internal
password: "${ANALYTICS_DB_PASSWORD}"
roles: ["admin"]
# Credentials via K8s Secret:
extraEnvFrom:
- secretRef:
name: seed-db-credentials
```

| `connections[].group` | No | Group label in sidebar |
| `connections[].color` | No | Hex color for badge (e.g., `#10B981`) |
**Environment Variables:**
| Variable | Default | Description |
