EvalCore

Snapshot testing for AI behavior — catch regressions offline in CI

Record once, replay forever

A live run captures every model request and response into a local SQLite cassette that CI can replay offline and deterministically at zero cost.

Anything can be a target

Point EvalCore at OpenAI-compatible endpoints, vLLM, Ollama, your own REST APIs, shell commands, or OTel/OpenInference traces — no SDK required.

Scorers that define 'good'

Stack contains, judge-rubric and other scorers in YAML to express exactly what a correct answer looks like for each case.

Regression gates and baselines

Compare against a baseline branch so only real regressions fail, and let the process exit code gate your pull requests.

Strengths & Pros

+Genuinely free and open source under Apache-2.0, with no usage-based pricing
+Deterministic offline replay removes flaky, expensive model calls from CI
+Single dependency-free binary that works regardless of your app's language
+Configuration is plain YAML plus JSONL, so suites are easy to review and version
