Tracely Ai

Tracely is an LLM observability and evaluation platform that connects production traces to continuous integration checks for AI agents. It traces agent runs over OpenTelemetry, grades each trace as it arrives with evaluators, clusters failures into issues, and lets a team freeze a failing trace into a regression test that blocks the pull request which would reintroduce the problem. It is built for teams shipping agents who do not want to hand author test datasets. The workflow runs in four steps: trace, detect, freeze and gate. Online evaluators use models as judges at the conversation, run or span level, and a failure on a blocking evaluator changes the verdict. A frozen case bundles recorded input along with tool and model fixtures, and the tracely replay command reruns the suite on every pull request offline and deterministically with no model spend, exiting with an error on a regressing merge. It instruments stacks including OpenAI, Anthropic, Google Gemini, LangChain, LangGraph, LiteLLM, CrewAI and Mistral, and any OTLP source. A dashboard replays each conversation as a scene. The self hosted edition is MIT licensed, includes every feature and costs $0. A hosted Free plan costs $0 a month with 20,000 traces a month and 7 day trace retention. The Team plan costs $49 a month with 1 million traces a month and 90 day retention.
