GitSpider is GitHub Actions monitoring for small teams. It watches every workflow run, flags the slow, flaky, and wasteful ones, and posts the regression, with the exact commit that caused it, right on the pull request (and in Slack), before your engineers feel it.
No signup. Try it on honojs/hono · vitejs/vite.
Three things. Done well.
When CI regresses, GitSpider comments on the pull request (and pings Slack) with the exact commit that caused it. The dev sees it where they already are, before it ships.
p95 duration, failure rate, time-to-recover, and throughput per workflow, with the bad PR flagged when today drifts past your baseline. Alerts debounce 6h so your channel stays sane.
26 detectors flag duplicated push/PR runs, missing concurrency & caches, always-failing jobs, silent cron death, Docker rebuilds and more, with the exact YAML fix, and recoverable minutes where they're honestly measurable.
Install → crawl → catch. Install in ~2 minutes, no YAML, no config.
Add the GitHub App to the repos you want watched: read access plus PR comments, no code writes. Two minutes, no YAML, no config.
GitSpider records every Actions run and learns each workflow's normal: duration, failure rate, billable minutes.
The moment a run drifts (slower, flakier, pricier), you're pinged in Slack, email, or right on the PR.
~2-minute install. Free to watch your CI. PR comments + Slack alerts on every paid plan.
