✓ Best for

Teams building real-time recommendation systems that require low-latency query responses and machine-learned inferences
Projects involving large-scale search engines where scalability and performance are critical
Applications requiring complex query processing over big data with support for machine learning

✓ Best for

Enterprise search with faceting/analyticsAggregations and large-scale relevance
Log and observability analyticsDoubles as a logging backend

Not ideal for

✕ Not for

Small projects or applications where the overhead of setting up a self-hosted solution is not justified
Real-time streaming use cases that require sub-second response times, as Vespa's architecture may introduce slight latency
