Typesense
Open-source search engine + cloud
Free tier + paidSearch, vector & RAGtypesense.org
What it is
A C++ search engine built as an open-source alternative to Algolia. Ships typo tolerance, faceting, geosearch, vector and hybrid search in a single self-contained binary. Typesense Cloud gives you a dedicated cluster billed by the hour with no limits on records or search operations.
Why it earns a slot
Fixed hourly pricing makes a search-as-you-type box safe to ship — you are not billed per keystroke. One
docker run gets an identical instance running locally.Know before you commit
The Cloud free tier is one-time, not monthly: 720 hours total per account, then the cluster starts billing. The server is GPL-3.0, which matters if you embed it.
Getting started
docker run -p 8108:8108 -v/tmp/data:/data typesense/typesense:29.0 --data-dir /data --api-key=xyz
Neighbourhood
How Typesense sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
