type=database now provisions a managed database via POST /databases (engine + plan pickers) instead of a hollow service row; template source navigates to the existing catalog with the project preselected (/templates?project= now seeds the deploy target). api-client gains createManagedDatabase + DatabaseEntity from generated schemas.

What is Containr?
Containr is an open-source control plane for Docker. It gives you a project-first deployment workflow — create a project, drop services onto a visual canvas, wire them together with environment variables, and deploy — without Kubernetes, without a cloud bill, and without giving up control of your infrastructure.
The UI is inspired by Railway's project canvas: services appear as nodes, connections are inferred automatically, and everything — logs, metrics, deployments, builds — is one click away.
Features
- Project canvas — visual service topology with groups, drag/drop layout, and auto-inferred connections
- Deployments — Docker-based deploys with history, logs, and rollback
- Git integration — deploy from GitHub, GitLab, Bitbucket, or Gitea; repository and branch pickers, webhooks, GitHub App support
- Builds — build pipeline with live status over WebSocket
- Service metrics — real CPU/memory/network telemetry from Docker stats
- Templates — one-click service catalog (databases, apps, tooling)
- Databases — managed database services with backup/restore actions
- Cron jobs — scheduled jobs with execution history
- Preview environments — per-project preview deploys
- Variables & environments — per-service env vars, production/preview/dev
- Node monitoring — host CPU, memory, disk, and network telemetry
- Security — audit logs, vulnerability scans, compliance reports
- Auth — Better Auth sessions (email + OAuth), per-user resource scoping
- Self-hosted networking — Traefik reverse proxy, optional Cloudflare Tunnel for exposure without port forwarding

docs/ Guides, OpenAPI spec, design documents
| Component | Default port |
|---|---|
| Frontend | 3000 (prod) / 5173 (dev) |
| API | 8082 |
| Auth sidecar | 3001 |
| PostgreSQL | 5432 |
| Redis | 6379 |
Quick Start
Docker Compose (everything)
cp .env.example .env # fill in secrets
docker compose up -d
Frontend at http://localhost:3000, API at http://localhost:8082.
Local development
docker compose up -d postgres redis # data services only
cd app/backend && go run ./cmd/server # API + embedded auth sidecar
cd app/frontend && npm install && npm run dev
Frontend dev server at http://localhost:5173.
Self-hosted with Traefik + Cloudflare Tunnel
See infra/docker-compose.yml and
docs/guides/CLOUDFLARE_SETUP.md.
Configuration
All configuration is via environment variables — see .env.example.
Required for production: JWT_SECRET, BETTER_AUTH_SECRET,
BETTER_AUTH_INTERNAL_TOKEN, database and Redis credentials.
Never commit .env or .env.prod. Both are gitignored; if a secret was
ever committed, rotate it.
