Unified BaaS vs. Compose-Your-Own Stack: Head-to-Head
Unified BaaS vs compose-your-own stack: which wins for your project? We compare cost, flexibility, and speed so you can choose with confidence.
Self-hosted Supabase is the open-source Supabase stack (Postgres, GoTrue auth, PostgREST, Realtime, Storage, Edge Functions, and Studio) running on your own servers, usually with Docker Compose, instead of on Supabase's managed platform. Powabase's Apache-2.0 self-host edition runs that same data plane unchanged and adds a RAG pipeline and agent runtime on top.

Supabase's official path is Docker Compose. You clone the supabase/supabase repository, copy its docker/ directory into a project folder, copy .env.example to .env, pull the images, and start the stack. On Linux, Supabase also publishes a setup script that does this for you, and a run.sh helper wraps start, stop, restart, and printing credentials. The stack runs Postgres, Studio, Auth (GoTrue), PostgREST, Realtime, Storage with imgproxy, Edge Runtime for functions, and postgres-meta, all behind an API gateway (Envoy in current releases). Supabase lists a minimum of 4 GB of RAM, 2 CPU cores, and 40 GB of SSD storage. You can drop services you don't need, such as Realtime or Edge Functions, from docker-compose.yml to save resources. Updates come from an update.sh script that merges the latest self-hosted/v* configuration over your files. Don't confuse this with the Supabase CLI's local development stack, which Supabase says is not hardened for production.
The defaults in .env.example exist to get the stack running, and Supabase is explicit that you should never start a real deployment with them. Before anything touches the internet, replace every secret and put the gateway behind TLS. Then set up email: GoTrue needs an SMTP server to send confirmation, magic-link, and password-reset emails, configured through the SMTP_* variables (Supabase suggests a provider such as AWS SES). Decide where Storage keeps files, local disk or an S3-compatible bucket, and plan for how big the Postgres volume will grow. Finally, keep the Postgres port off the public network and reach it through the gateway or a private connection.
Supabase's own docs list what the managed platform has and self-hosted Supabase doesn't: branching, advanced metrics beyond logs, managed backups and point-in-time recovery, analytics and vector buckets, ETL, and the platform management API. Self-hosted Studio also runs a single project and has no organizations. So if you want three environments, you run three stacks. The work moves to you as well. Backups are your own pg_dump or WAL archiving, upgrades are your job to test and roll out, and monitoring, log retention, and alerting are yours to wire up. None of this is unusual for running Postgres in production, but budget for it. In return you get full control of where data lives, no per-project platform fees, and a stack you can run inside a private network. Supabase recommends self-hosting when you need that control, have compliance rules that rule out managed services, or need an isolated environment.
Self-hosted Supabase gives you pgvector, so you can store embeddings and run similarity, keyword, and hybrid search in SQL. Everything around those queries is left to you. You need a parser for PDFs, Office files, and scanned images, a chunking strategy, a job that calls an embedding model when documents change, a reranker, and some way to run an agent that calls tools and remembers sessions. Supabase documents an automatic-embeddings pattern built from Edge Functions, pgmq, pg_net, and pg_cron, which works but is yours to maintain. Agent frameworks such as LangChain run in a separate service with their own state. On a self-hosted stack every one of those pieces is another container to deploy, secure, and upgrade. If your app is mostly CRUD with a little semantic search, plain Supabase is enough. If documents and agents are the core of the product, a stack that already has the AI layer will save you most of that work.
The Powabase self-host edition is a single-project stack under Apache-2.0. Its data plane is the upstream Supabase self-hosted stack running the official images unchanged: GoTrue, PostgREST, Storage with imgproxy, Realtime, postgres-meta, and Postgres 15 with pgvector. On top of that it adds the Powabase AI service and a background worker for sources, knowledge bases, agents, and workflows, with Redis as the job queue and a Studio fork that shows the AI features, for 12 services behind a Kong gateway. Setup is four commands: copy .env.example, run gen-keys.py to generate your secrets, set your OPENAI_API_KEY (embeddings need a key, and you can add Anthropic and other providers), and run docker compose up -d. Image versions are pinned, and updating is a git pull, docker compose pull, and docker compose up -d. Because the base is Supabase, your existing SQL, RLS policies, and supabase-js code carry over.

How Powabase does it
Powabase gives you the Supabase backend you already know with the AI layer built in, on your own servers or ours. The self-host edition is one docker compose up under Apache-2.0. Powabase Cloud gives every project its own Postgres instance in an isolated environment, and Enterprise adds a supported Kubernetes Helm chart and private hosting.
