Snapshot testing for AI behavior — catch regressions offline in CI
A live run captures every model request and response into a local SQLite cassette that CI can replay offline and deterministically at zero cost.
Point EvalCore at OpenAI-compatible endpoints, vLLM, Ollama, your own REST APIs, shell commands, or OTel/OpenInference traces — no SDK required.
Stack contains, judge-rubric and other scorers in YAML to express exactly what a correct answer looks like for each case.
Compare against a baseline branch so only real regressions fail, and let the process exit code gate your pull requests.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.
