ReplayRigor

ReplayRigor is a web app plus lightweight desktop runner that captures deterministic “interaction replays” from end-to-end UI tests and turns intermittent failures into something you can reproduce locally in minutes. Instead of only storing screenshots and logs, it records DOM snapshots, network traffic (HAR), console output, browser performance traces, and the exact user-event timeline, then packages it into a shareable replay artifact. When a CI job flakes, developers can open the artifact and step through the run, compare it to the last passing baseline, and see what changed (timing, selectors, API responses, third-party scripts). It also flags common root causes (race conditions, unstable selectors, animation timing, dependency outages) and suggests concrete fixes, but does not pretend to “auto-fix” your suite. The goal is faster debugging and fewer reruns, not magic.
