Licence, self-hosting, OpenTelemetry support, pricing, data residency and retention for each platform — every value carries its source URL and the date it was checked. - [Pricing](https://evalindex.dev/pricing): EvalIndex sells two one-off things: a labelled vendor-authored block on a record, and an expedited assessment that buys queue position only. Neither can be bought yet; prices exclude VAT. - [About the index](https://evalindex.dev/about): EvalIndex is an index of LLM observability platforms, compared attribute by attribute, with a published source and a check date behind every value. - [Operator disclosure](https://evalindex.dev/disclosure): Who writes the assessments, who decides what is listed, who checks the sources, who answers the mailbox, and what this site's operator cannot know. - [Inclusion criteria](https://evalindex.dev/criteria): The published rules that decide what EvalIndex lists, queues, refuses, marks and removes — applied uniformly to every product, and none of it for sale. - [Queue and assessed set](https://evalindex.dev/queue): Every state a product can be in on EvalIndex, with dates: the assessed set, the queue, published records, the two refusals, delistings and discontinuations. - [Paid placement policy](https://evalindex.dev/paid-placement): The two one-off things EvalIndex offers — neither can be bought yet — what each one does, and what no payment can buy: inclusion, position, a verdict, or a word of an assessment. - [Accessibility of this site](https://evalindex.dev/accessibility): EvalIndex targets WCAG 2.2 AA. This page says what is actually tested and on which pages, what is not tested at all, and how to report a barrier you hit. - [Privacy notice](https://evalindex.dev/privacy): How EvalIndex handles personal data: the correspondence sent to its mailbox, the replies and first-contact messages sent out, the four processors involved, how long things are kept, and your rights. - [Reporting a security problem](https://evalindex.dev/security): How to report a security problem in EvalIndex: where to send it, what to include, what happens next, and the honest scope of the running system. ## Data - [index.json](https://evalindex.dev/index.json): every record and every attribute value, with its source URL and check date, as JSON.
