I built Altus 4 because I was frustrated with spinning up Elasticsearch/Solr just to get decent search.
Many apps already use MySQL, but its built-in FULLTEXT search is often too basic.
Altus 4 bridges that gap:
- Adds AI-powered semantic search on top of MySQL FULLTEXT
- Handles natural language queries ("show me users from last month in London")
- Optimizes queries and provides performance insights
- Works across multiple databases without extra infrastructure
- Includes analytics, monitoring, and API key auth out of the box
It’s open source (Apache 2.0) and runs in Node.js + TypeScript, with MySQL + Redis underneath.
You can be up and running in minutes without migrating your stack.

I’d love feedback — especially from people running MySQL in production. Does this scratch an itch for you? What would make it more useful?
