Why people look past Vespa
Nothing on the record flags a reason to move. Vespa has a free tier. People still switch over fit and workflow, and those are not things a catalogue entry can measure, which is what the comparisons below are for.
What each alternative does differently

What you would be giving up
Vespa is most often brought in for build rag systems with semantic search over documents, power e-commerce search with ml ranking, create recommendation engines for personalization, implement real-time search for news or feeds, deploy private semantic search over sensitive data. Anything replacing it has to cover the ones you actually depend on, and a cheaper tool that misses one of them is not cheaper.
Two things this page cannot settle. It compares on price, model, tier count and rating, because those are the fields the category listing carries, feature-level differences need both full records, which is what the head-to-head pages load. And the ratings are third-party aggregates imported with each entry rather than reviews written here, so a 0.2 difference between two tools is noise rather than a finding.
If Vespa is broadly right and the question is cost, the Vespa pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Databases category lists everything the directory holds, and best databases tools ranks them.
Vespa runs on cloud, self-hosted. Platform coverage is not carried on the category listing for the alternatives, so it is one more thing to check on each head-to-head page rather than here.
