The Supabase alternative
when all you need is Postgres.

The most common reasons we hear: the bill grew unpredictably as compute add-ons, storage, and egress stacked up; vector workloads needed expensive compute upgrades just to keep indexes in memory; or the team only used the database and paid for a platform. If any of those sound familiar, a focused managed Postgres is usually cheaper and faster.

Almost always, for database-centric workloads. A Supabase compute add-on comparable to our Solo VM runs around $105/month; Solo is $29/month on dedicated NVMe. At the same compute size we typically come out 65%+ cheaper, with no egress or storage line items. Send us your row counts and current plan and we will give you a realistic number for your workload, not a marketing number.

Supabase is an excellent platform with a broad feature set: auth, file storage, edge functions, realtime subscriptions, and auto-generated APIs. Rivestack does none of that. It is managed PostgreSQL with pgvector, done well. If your app depends on Supabase Auth or Realtime, keep them (or replace them first). If you use Supabase as a Postgres database, you give up nothing.

Supabase is standard Postgres, which makes this one of the easiest migrations in infrastructure. pg_dump / pg_restore handles most databases in minutes; for larger always-on systems we use logical replication and a sub-minute cutover. Migration help is included free: we will plan it with you and sit in the cutover if you want us to.

Yes, and usually faster. pgvector is pre-installed and tuned, and your indexes run on local NVMe instead of cloud block storage. We measure recall@10 0.90+ at ~2 ms single-client p50 on 250k × 1536 vectors, which is ~1,600 QPS at 16 clients on a Starter node (2 vCPU / 4 GB; full tables at /pgvector-benchmarks-measured), and ~4,465 QPS on a Scale node that also holds a 1M × 1536 index hot, from a same-region app. Your existing pgvector schema, indexes, and queries move over unchanged with your data.

Your data is encrypted in transit and at rest, backed up daily to separate S3-compatible storage with point-in-time recovery, and HA clusters run Patroni-managed automatic failover. And because everything is vanilla PostgreSQL, you can pg_dump your entire database and leave at any moment, and no lock-in is the strongest guarantee we can offer.

You choose EU Central (Falkenstein, Germany) or US East (Virginia). EU databases and their backups never leave the EU, and we are an EU company, so DPAs are available on request. For European teams this is often simpler than configuring residency on a US-based platform.

Yes. The free tier gives you a Postgres database with pgvector in about a minute, no credit card. Load a sample of your data, run your real queries, and compare latency before you commit to anything.
