Backenly vs Modal

Your coding agent uses MCP tools to create tables, enable auth, write row-level security policies, connect integrations and turn on realtime — all against a live database rather than generated boilerplate.

Backenly registers guarantees about your backend, checks them every minute, detects breakage, proposes repairs, applies the safe ones and then verifies the fix by re-running the original check.

Additive fixes are applied and snapshotted automatically; auth changes, destructive statements and irreversible operations always pause for a human decision.

Each project lives in its own PostgreSQL schema with direct connection strings, pgvector, REST APIs served by PostgREST and pg_dump exports.
