Athina AI
Collaborative LLM evaluation and observability platform for teams shipping AI features to production.
Pick Athina AI if you need a shared eval and observability layer that PMs, QA, and engineers can all work in without stitching together three separate tools.
Skip it if you want a fully open-source stack or need self-hosting without committing to an Enterprise contract.
Athina AI is an end-to-end evaluation and monitoring platform for LLM applications, covering the full lifecycle from prompt experimentation through production tracing. It offers 50+ preset evals (including OpenAI and Ragas metrics), custom LLM-as-a-judge or Python-function evaluators, human annotation queues for QA teams, and continuous online evals that run against live production logs.
What sets Athina apart is that it tries to be a shared workspace rather than a developer-only tool: product managers get a no-code AI flow builder, data scientists get SQL-style dataset analysis, QA teams get annotation UIs, and engineers get SDKs and a GraphQL API. Pricing starts with a free Starter tier (10k logs/month, unlimited prompts), then jumps to custom-priced Pro and Enterprise plans, with self-hosting and SOC-2 gated behind Enterprise.
Integrations span Azure OpenAI, AWS Bedrock, and custom model endpoints, and the platform is model-agnostic by design. The main caveat is that pricing above the free tier is opaque, and non-Enterprise customers can't self-host, which is a real constraint for teams with strict data-residency requirements.
Athina is one of the more mature dedicated LLM eval platforms, and the cross-functional focus is genuinely useful once you have non-engineers signing off on prompt changes. The free tier is generous enough to trial seriously, but the opaque paid pricing and Enterprise-gated self-hosting will push some teams toward open-source alternatives like Langfuse.
