free tool live · Postgres first · MySQL/Oracle/SQL Server next
The AI database performance coach
that covers every major engine.
Connect read-only. Paste an EXPLAIN, slow log, or AWR. Get prioritized fixes with the exact DDL — in plain English. Built by a DBA who's lived in Postgres, MySQL, Oracle, and SQL Server.

Why this exists
Slow queries kill product velocity.
The 200ms creep to 2s happens in production, not staging. By the time a DBA sees it, your P95 already tanked.
DBAs are rare and expensive.
Most teams under 100 engineers don't have one. The ones that do are juggling six databases each.
Existing AI tools are single-engine.
pganalyze is Postgres-only. Releem is MySQL-only. EverSQL got acquired. OtterTune shut down. SolarWinds DPA isn't AI-native.
How TuneStack is different
Four engines, one product.
Postgres, MySQL, Oracle, SQL Server. Same interface, same workflow. Built by one team that actually understands each.
DBA-grade reasoning, not pattern matching.
Agentic LLM loop with tools: read pg_stat_statements, simulate indexes via HypoPG, validate rewrites with sqlglot before surfacing anything.
Human-in-the-loop, not auto-apply.
OtterTune's tombstone: never auto-apply. We generate the DDL, show the plan diff, and open a pull request in your migration tree. You review. You merge.
Who it's for
Backend engineers without a DBA.
You read EXPLAIN occasionally and Google what “sequential scan” means. TuneStack turns a slow query into a walkthrough, a fix, and a pull request.
DBAs and architects at larger shops.
You know what's wrong — you just want the 60-minute investigation done in 60 seconds, and the fix to land in the migration tree, not a Slack DM.
