OptiSchema Slim – Local-first AI tool for PostgreSQL performance tuning

Summary: OptiSchema Slim is a local-first AI tool that analyzes PostgreSQL databases for bloat, unused indexes, slow queries, and workload issues using configurable thresholds and scan history. It provides deterministic scoring with AI explanations and enables testing of “what-if” index scenarios by comparing query plans and estimated costs.

What it does

It scans PostgreSQL for performance problems, offers detailed EXPLAIN plan breakdowns, and lets users test and compare hypothetical indexes with before/after query plans and cost estimates.

Who it's for

Database administrators and developers seeking data-driven insights to optimize PostgreSQL performance.

Why it matters

It replaces guesswork in index tuning by providing AI-driven analysis and direct comparison of index impact on query costs.
