| Free tier | Free: 500 MB database, shared CPU, 2 active projects (paused after 1 week inactivity) |

| Cheapest paid plan | $25 a month |
| Usage price | Pro: 8 GB disk per project then $0.125/GB; compute from $10/month (Micro; first instance covered by $10 credits) |
| Good to know | Vector search is plain Postgres + pgvector, so cost is the database/compute plan; no per-vector pricing. Egress 250 GB then $0.09/GB on Pro. Hosted MCP also at https://mcp.supabase.com/mcp. |
