Common reasons people leave Chroma: hosted Chroma Cloud is being wound down after the Replit deal, and you run, scale and back up the database yourself. We ranked 6 alternatives by how directly each one replaces Chroma, then by reviews, real visits and how recently each app's facts were checked against its own website. Qdrant currently ranks first.

Chroma has been acquired. Signed an agreement to join Replit on 23 October 2026, with Chroma Cloud being wound down, according to the Chroma blog.
