Supavisor
Supavisor is a Postgres connection pooler for routing client connections into pools of native PostgreSQL connections.
What Supavisor is
Supavisor is a Postgres connection pooler for routing client connections into pools of native PostgreSQL connections. It supports multi-tenant connections across Postgres instances or clusters, as well as single-tenant use as a PgBouncer replacement. Teams can choose transaction, session, or native pool modes, and client credentials can be checked against tenant user records or an authentication query. The project describes tenant-level throughput visibility and a Prometheus metrics endpoint, alongside management documentation through an OpenAPI specification at `/api/openapi` and Swagger UI at `/swaggerui`. Supavisor is self-hosted and Apache-2.0 licensed, with a free plan. Its deployment options include Supabase Dashboard, CLI, and MCP. Installation begins with a PostgreSQL database for tenant data, and a Docker Compose command is provided for PostgreSQL 14. The project supports rolling and blue-green deployments, but is not intended for serverless use. It does not depend on Kubernetes.
Good
- Supports transaction, session, and native pool modes
- Multi-tenant connections span multiple Postgres instances or clusters
- Provides tenant throughput visibility and Prometheus metrics
- Free and Apache-2.0 licensed
Watch out
- Not intended for serverless environments
- Requires a PostgreSQL database for tenant data
Who it suits
Supavisor suits teams operating PostgreSQL that need connection pooling across tenants or a single-tenant PgBouncer replacement. It is aimed at self-hosted deployments rather than serverless environments.
Verdict
Supavisor combines several pooling modes with tenant-aware connection management and monitoring. Its self-hosted, free model may suit PostgreSQL teams, provided serverless deployment is not required.
