Open-source Firebase alternative with usage-based pricing that can spike on projects
TL;DR: Supabase carries a Risk Score of 31/100 (Mixed Signals) based on 3 documented complaints — mostly minor issues, but worth knowing about.
Supabase is an open-source backend-as-a-service platform providing a Postgres database, authentication, storage, and edge functions. Pricing includes a free tier with paid plans starting at $25/month per project, scaling with database size, bandwidth, and compute usage.
Supabase's open-source model and generous free tier have made it a favorite for indie developers and startups, but usage-based add-ons (bandwidth, compute, storage) can generate meaningful overage charges as a project grows, and free-tier projects are paused after a period of inactivity.
Each complaint type is weighted differently in the Risk Score. Billing and marketing deception weigh heaviest.
Complaints are sourced from public platforms spanning US, UK, and global consumers. Each report links back to its original source.
| Platform | Reports | Who's reporting |
|---|---|---|
| 2 | US & global users | |
| G2 | 1 | Global B2B buyers |
