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, MTTR, and throughput per workflow — with the bad PR flagged when today drifts past your baseline. Alerts debounce 6h so your channel stays sane.
10 detectors flag duplicated push/PR runs, missing concurrency & caches, always-failing and oversized matrix jobs — each with the dollars you'd recover.
Install → crawl → catch. Live in 15 minutes.
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.
15-minute setup. Free to watch your CI. PR comments + Slack alerts on every paid plan.
