Catch CI regressions before they ship.

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.

What you get

Three things. Done well.

Blame the commit, on the PR

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.

The trends that matter

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.

Waste detection + cost

10 detectors flag duplicated push/PR runs, missing concurrency & caches, always-failing and oversized matrix jobs — each with the dollars you'd recover.

How it works

Install → crawl → catch. Live in 15 minutes.

Install

Add the GitHub App to the repos you want watched — read access plus PR comments, no code writes. Two minutes, no YAML, no config.

Crawl

GitSpider records every Actions run and learns each workflow's normal — duration, failure rate, billable minutes.

Catch

The moment a run drifts — slower, flakier, pricier — you're pinged in Slack, email, or right on the PR.

Engineers wait. GitSpider watches.

15-minute setup. Free to watch your CI. PR comments + Slack alerts on every paid plan.
