Vespa
A search platform combining text, vector and structured retrieval with machine-learned ranking, model inference and real-time data updates.
About Vespa
Search and recommendation systems need retrieval and model-based ranking over changing data.
Who it’s for
- Engineers building search and recommendation services
- Teams developing retrieval for AI applications
When to consider it
Consider Vespa when retrieval, ranking and model inference need to run within the same search platform.
Tradeoffs & limitations
- The engine is Apache-2.0 licensed; running your own instance requires deploying and operating it, with Vespa Cloud offered as an alternative.
