Polymathy vs the alternatives.
Polymathy is a single Rust service, not a platform and not a SaaS. These comparisons are written to stay useful even when the alternative is the better fit — we say plainly when it is.
vs a full answer-engine platform
Polymathy vs Onyx
Onyx ships the whole product — connectors, document index, and a chat UI. Polymathy ships the fetch-and-chunk seam in the middle. Different altitudes, not really competitors.

Polymathy vs Algolia + LLM
Algolia + LLM is the SaaS path over a corpus you own. Polymathy is the self-hosted, public-web path via SearxNG. The dividing line is who owns the corpus.
Read the comparison →The short version: if you want the answer-engine experience itself, look at Onyx. If you own the corpus and want hosted infrastructure, look at Algolia. If the corpus is the public web and you want one Rust binary you can read end to end, that's Polymathy.
