Typesense
GPL-3.0 search with no enterprise asterisk, tuned for speed.
Typesense is a C++ search engine designed around a specific promise: typo-tolerant results in milliseconds, with an in-memory index and a clustering story that was built in rather than added. It has an Algolia-compatible InstantSearch adapter, native vector and hybrid search for semantic queries, and — the distinction worth noting against Meilisearch — a plain GPL-3.0 licence with no separately licensed enterprise components. Around 26.4k stars. The trade for the in-memory design is RAM: your index has to fit in it, which is a budgeting question rather than a limitation.
What it does well
- +Plain GPL-3.0 with no enterprise-edition carve-out
- +Very fast — in-memory index, consistently low latency
- +Built-in clustering and high availability, not an afterthought
- +Native vector and hybrid search for semantic queries
Where it falls short
- −Index must fit in RAM, which sets a real budget floor at scale
- −Smaller community than Meilisearch
- −More configuration needed to reach the same relevance out of the box
- −GPL-3.0 copyleft is worth reading if you plan to modify it
