memviz
A local vector memory explorer with a modern UI inspired by Supabase and Pinecone.
Browse, search, visualize and manage the SQLite-vec database created by
MCP Memory Service.
A quick note
I'm a sysadmin by trade, not a developer. My coding background is some C++ from many years ago. I built memviz entirely through vibe coding with Claude Code as a way to test AI-assisted development workflows. The whole thing was built in about two days.
It works, it has 349 tests, and I use it daily. But the code reflects the fact that an AI wrote most of it while I steered. If you spot rough edges, odd patterns, or things that could be done better, I'd genuinely appreciate the feedback. PRs and issues are very welcome.
