I’ve been using Pinecone across a few projects and found it really hard to inspect what’s there or understand why certain queries behave the way they do.

I built Pinecone Explorer as a simple, native desktop tool to explore indexes, vectors, metadata, and query results without writing ad-hoc scripts.

What it supports today:

Connect to multiple Pinecone projects and indexes
Browse namespaces, vectors, and metadata
Run semantic queries and inspect similarity scores
Easily work with dense, sparse, and hybrid indexes
Test reranking
Native macOS app, fully open source (MIT)

This isn’t meant to replace Pinecone’s console, it’s just a tool I wanted while building and debugging retrieval systems.

I’d really appreciate feedback:

What feels missing?
What would make this more useful in your day-to-day work with Pinecone?

Thanks for checking it out.
