What is Infinity?
An AI-native database built for language model applications, offering rapid hybrid search across dense vectors, sparse vectors, tensors, and full-text data. It features a single-binary architecture deployable via Docker or binary without external dependencies, with a Python API for developer convenience.

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Infinity, not the verdict.
