Supabase vs Nile
A comparison of Supabase and Nile built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
- Pick Supabase if
- Teams who want Postgres plus auth, storage and generated APIs from one vendor on a fixed monthly bill, and who would otherwise assemble those pieces themselves.
- Pick Nile if
- Multi-tenant SaaS where every customer wants isolation — Nile makes a database per tenant the default shape rather than something you build on top of Postgres.
6 sourced criteria separate them:
- Entry paid plan
- Supabase: $25/month for the Pro plan, including the first project and $10/mo of compute credits; additional projects from $10/mo
- Nile: $15/month for Pro, which carries a production SLA. Scale is $350/month.
- Pricing model
- Supabase: Fixed monthly plan per organisation plus per-project compute, billed hourly by instance size
- Nile: Priced on queries rather than instances, with a $15 base for Pro. Nile's own framing is "Pay for queries, not for instances", and additional tokens are $0.05 per million.
- Storage (entry plan)
- Supabase: 8 GB disk per project on the Pro plan; 500 MB on Free
- Nile: 5 GB on Pro, then $1.00 per additional GB.
- Engine
- Supabase: PostgreSQL
- Nile: PostgreSQL, with tenant isolation as a first-class concept — databases, tenant databases and vector embeddings are all described as unlimited.
- Connection limit
- Supabase: 60 direct and 200 pooled connections on the Micro instance included with Pro; both scale with instance size
- Nile: 10,000 connections on Pro, with connection pooling included.
- When idle
- Supabase: Free projects are paused after one week of inactivity and must be restored manually; paid projects are not paused
- Nile: No cold start on Pro — Nile lists it as a plan feature rather than a behaviour to configure.

Consider something else if…
- Supabase: You want only a database. Much of the $25 covers a platform you may not use, and free projects are paused after a week of inactivity, which is not the same as scaling to zero.
- Nile: Several of the features on its own pricing table are marked Coming soon, including branching, backups and provisioned compute, so what is bought today is narrower than the table suggests.
