Interactive Local CI Pipeline Debugger That Mirrors Cloud Runners Exactly
Developers waste hours on push-and-pray CI debugging because no tool lets them interactively step through pipeline jobs locally in the exact same environment as their cloud runner. Earthly's shutdown left a gap, Act only partially emulates GitHub Actions, and Dagger requires rewriting your entire pipeline in Go/Python/TS.
Don't build another CI platform. Build a debugger that wraps existing CI configs. If you can parse a GitHub Actions YAML file, spin up the exact runner image, mount the repo, and let developers set breakpoints between steps, you solve the 'push and pray' cycle without asking anyone to rewrite their pipeline.

Earthly's July 2025 shutdown removed the most developer-friendly local CI option. Act remains the go-to for GitHub Actions but its emulation gaps are well-documented. No tool provides true interactive debugging where you can pause, inspect state, and step through CI jobs locally.
