turbopuffer ranks #8 of 20 in our vector databases testing. object-storage economics with the best namespace multi-tenancy.
78/100
the architecture the rest of the category converged on, with genuinely good per-tenant isolation — behind unpublished unit rates and no self-host option.
why people look for an alternative
−per-unit rates are not published anywhere fetchable
−closed source with no self-host option
−no free tier, and higher tail latency by design
stay with turbopuffer if excellent economics on large, mostly-cold corpora is the thing you care about most — nothing below beats it on that.
#4 in vector databases · the licence objection to using it for vectors is largely obsolete
85/100
verdictbest-in-class hybrid retrieval with transparent serverless pricing — and its dense and sparse vector code sits in the agpl-licensed tree, not the restricted one.

pros
+vector search is available under agplv3, not licence-restricted
+best-in-class hybrid with real bm25 and rank fusion
+transparent serverless pricing with 50gb free on vector profiles
+better binary quantization and mature filtering
cons
−jvm heap tuning and real operational weight
−licence structure is complex even where it's permissive
#5 in vector databases · multi-tenancy and hybrid search, priced per million dimensions
84/100
verdictthe strongest combination of hybrid search and per-tenant isolation here — with a pricing model that punishes large embeddings in a way no competitor's does.

#7 in vector databases · storage at six cents a gigabyte, and it reprices the floor of the market
80/100
verdictroughly five times cheaper per gigabyte than the premium managed options, and explicitly built for cost rather than latency — choose it deliberately, not by default.

verdicta full search and ranking engine rather than a vector store — if ranking quality is your product, rank it second; if you just need rag, it's overkill.

verdictthe zero-operations promise is real and worth money to some teams — but you cannot tune it, cannot self-host it, and cannot easily predict the bill.
