# Databases

This page lists which SQL databases pREST supports today and what is still on the roadmap — the canonical **support labels**.

PostgreSQL is **native**. Postgres-compatible engines are **certified** or documented with caveats on that adapter. MySQL, SQLite, and SQL Server are **Roadmap** until dedicated adapters ship.

## Support labels

| Label                       | Meaning                                                      |
| --------------------------- | ------------------------------------------------------------ |
| **Native**                  | First-class dialect adapter                                  |
| **Certified**               | Runs on the native adapter with a published features matrix  |
| **Compatible with caveats** | Connects via PostgreSQL wire protocol; known gaps documented |
| **Hosted PostgreSQL**       | Managed PostgreSQL — same native adapter                     |
| **Roadmap**                 | Planned — not available yet                                  |
| **Experimental**            | Incomplete; use only with explicit expectations              |

## FAQ

### What databases does pREST support?

Today: **PostgreSQL** (native) and engines that use the PostgreSQL wire protocol, with per-engine matrices. Other SQL families are planned — they are not installable yet.

### Is Aurora / Neon / Supabase supported?

Yes, as **Hosted PostgreSQL**. Use the same connection settings as PostgreSQL. See [Aurora PostgreSQL](/databases/aurora-postgresql.md).

### When will MySQL or SQLite work?

They are Phase 2 and Phase 3 on the [roadmap](/databases/roadmap.md). Do not expect a MySQL or SQLite connection string to work with current releases.
