Solid for our team
We rolled this out across the team last quarter and high performance due to Rust implementation. REST and gRPC APIs fits neatly into how we already work, and horizontal scaling and sharding removed a step we used to do by hand. but it has held up under daily use.
Use it every day
Honestly didn't expect to like it this much. Payload-based metadata filtering is exactly what I needed, and open-source with a permissive license. I do wish requires familiarity with vector embeddings, but I reach for it almost every day now and it just clicks.

Skeptical, then convinced
I went in skeptical — most tools in this space overpromise. It actually delivers on rEST and gRPC APIs, and high performance due to Rust implementation caught me off guard. Fewer enterprise features than some commercial rivals is why this isn't a perfect score, still, I'd recommend giving it a real trial.
Years in this space
I've evaluated a lot of these over the years. What stands out here is payload-based metadata filtering — handled better than most — and open-source with a permissive license. Fewer enterprise features than some commercial rivals is my one real gripe. Worth the time if this is your use case.
