DuckLake Inspector — a local browser and health checker for DuckLake catalogs 🦆
I’ve been spending my weekends exploring DuckLake and kept wanting something that sits between the DuckDB CLI and a full BI tool for inspecting lake_meta.db files.

For each finding, it generates copy-paste DuckLake remediation SQL so you can inspect and clean things up safely.
There’s also an optional executive summary powered by Claude or GPT if you add an API key in .env.local.
One-command Docker run.

Feedback and PRs are welcome. I’m especially interested in what analyzers people would find useful next — I’m currently thinking about column-level cost, delete-file inspection, and a snapshot time-travel slider.
