How we research and present tools

18 vendors · 72 primary sources · 0 paid placements · re-checked at least every 90 days.

What we include

Software for evaluating AI and LLM applications: eval platforms, eval frameworks with a hosted or enterprise offering, and LLM observability tools with evaluation features. Each must have an active public website. Evaluation services companies are out of scope.

Sources

Each fact comes from the vendor’s own website, documentation, pricing page, trust portal, code repository, or a primary release such as a company announcement. Every profile lists its sources and the date we checked them.

What we do not do

We do not test tools, score them, rank them, or publish reviews. We do not claim partnerships or customer relationships we cannot source. Where a vendor publishes no price, we say “Contact vendor”. Where we found no certification, we say so and suggest asking for documentation; that is not a finding that the vendor lacks one.

Certifications

Listed as the vendor states them. Scope can differ by product, plan, or deployment model, so we recommend requesting reports.

Order

Tool lists default to alphabetical order. Filters and comparisons change only what is shown, not any ranking.

Updates

We re-check sources at least every 90 days and when vendors announce material changes such as acquisitions or pricing changes.

Commercial policy

Today we accept no payment for listings or placement. If sponsorship is introduced later, sponsored items will be labeled, kept out of editorial comparisons and filters’ default order, and disclosed on this page.
