## What it is
Supavisor is a cloud-native, multi-tenant Postgres connection pooler built in Elixir/Erlang. It proxies millions of client connections into a stateful pool of native Postgres connections, enabling zero-downtime scaling and high availability across a distributed cluster.

## Use cases
- pool postgres connections for serverless functions
- scale postgres connections to millions of clients
- replace pgbouncer with a distributed pooler
- manage multi-tenant postgres connection pooling
- avoid connection exhaustion in postgres
- proxy postgres connections over http and tcp
- run zero-downtime database compute resizing

## When to choose
- you need to pool postgres connections for many tenants or serverless clients
- you want a horizontally scalable, cloud-native alternative to pgbouncer
- you need zero-downtime scaling of postgres compute behind a proxy

## When to avoid
- you only need simple single-node connection pooling for one app
- you use a database other than postgres
- you cannot operate a distributed elixir cluster

## Facets
- artifact type: service
- maturity: active
- function: database, proxy, caching, middleware
- domain: databases, cloud-computing, backend, infrastructure-as-code
- platform: cloud, self-hosted
- tags: postgres, connection-pooler, multi-tenant, elixir, erlang, cloud-native, serverless, linux, docker, web-server
