GitHub Actions Cost Audit

Drop a GitHub repo URL. Within 1 hour, get a deterministic audit of every CI cost leak in your .github/workflows/*.yml and Dockerfiles — ranked by $/mo, with before/after YAML diffs you can paste straight into a PR.

Why this product, why now: GitHub Actions' December 2025 pricing change (HN discussion #46291156, 639 comments) raised per-minute rates and killed BuildJet — the most popular self-hosted runner alternative. Teams that ignored CI costs for years are now opening monthly invoices that doubled. The 10 patterns we check below are the deterministic root causes.

→ Synthetic sample report ($1,400/mo, 8 findings)

Deterministic static analyzer. No LLM-in-the-loop. Same engine on every repo. We don't manufacture findings to justify the $79 — small/clean repos return small reports and a partial refund.

What's in the audit

1. Executive one-pager

Top findings ranked by $/mo. Total annualized CI savings. Read in 60 seconds, decide what to ship this week.

2. Before/after YAML diffs

Actual patch snippets for the top leaks. Paste into a PR against .github/workflows/*.yml. No "go optimize your pipeline" handwaving.

3. Per-workflow minute map

Every workflow in your repo, with estimated runner minutes/month, OS distribution (linux/macos/windows), and $ burned. Concentrate effort where it matters.

4. Specific fix instructions

For each leak: confidence rating, expected savings, implementation effort (LOC), and rollback strategy if the fix breaks a job.

5. 30-day re-audit voucher

Implement the fixes, then re-submit the same repo. We re-run the analysis. If your bill didn't drop by $79+, full refund.

+ Docker/buildx coverage

We also scan Dockerfiles + docker/build-push-action steps for missing GHA cache, untagged base images, and bloat that re-builds layers every run.

The 10 patterns we check

The analyzer is 10 deterministic YAML + Dockerfile patterns. Every finding includes a confidence rating, $/mo impact estimate, before/after diff, and rollback note.

#	Pattern	Typical $/mo
1	Missing `actions/cache` for npm/yarn/pnpm/pip/poetry/maven/gradle	$200-600
2	No `concurrency.cancel-in-progress: true` (stale PR runs keep burning)	$100-400
3	Matrix includes `macos-latest` for jobs that don't need macOS (macOS = 10× linux pricing)	$150-500
4	`docker/build-push-action` without `cache-from: type=gha`	$80-300
5	Artifact bloat — uploading `node_modules` or `.next/cache` with `actions/upload-artifact`	$30-150
6	`actions/checkout` with `fetch-depth: 0` when shallow would suffice	$30-100
7	Missing `concurrency:` group (sibling to #2 — applies even when cancel-in-progress is off)	$40-150
8	Cron `schedule:` firing every 5 min for a "daily" summary job	$20-80
9	Redundant `npm install` across multiple jobs in same workflow (no shared cache step)	$60-200
10	`runs-on: macos-latest` for pure linux work (Playwright Linux containers, Python wheels for x86_64)	$200-700

Typical full-audit sum: $900-$2,100/mo on a mid-sized Next.js or Python monorepo with 3-6 active workflows. Outlier: we've seen $4K+/mo on repos with 30+ matrix jobs that include macOS unnecessarily.

How it works

Pay $79 via PayPal (top of page). You're redirected to a thank-you page that asks for your GitHub repo URL + email.
Drop the repo URL (any GitHub repo you have access to — private OK, we use a read-only fine-grained PAT you generate yourself).
Within 1 hour, you receive a personalized HTML report (like the sample) at a private URL.
Implement the fixes. Most customers ship the top 3 within a single PR.
30 days later, redeem the re-audit voucher. We re-run and quantify whether the bill actually dropped.

What this isn't

This is...	This is not...
A one-shot, static-analysis audit of your workflow YAML + Dockerfiles	A monthly SaaS subscription with seat pricing
YAML-level findings you can paste into a PR	Runtime telemetry requiring a GitHub App install
Deterministic regex + YAML AST patterns (no LLM-in-the-loop)	"AI told me your CI is bad" handwaving
Vendor-agnostic (works on GitHub-hosted + self-hosted runners)	A migration service to BuildJet/Depot/Namespace (their pitch, not ours)
Read-only (we never push, never merge, never trigger a workflow)	A CI security scanner — see prompt-library audit for that lane

First-3-customers beta pricing

This is a brand-new product. The 10-rule analyzer is validated against 30+ public OSS repos (Next.js, FastAPI, Rails, Django), but $79 GitHub Actions Audit has shipped zero paid audits yet.

Honest first-customer offer: the first 3 customers pay $59 instead of $79 via direct PayPal invoice. Email miloantaeus@gmail.com with subject "GitHub Actions audit — first 3" and we'll send the $59 invoice instead of using the $79 button above. In exchange: a 90-day follow-up audit and permission to anonymize learnings into the rule library.

Why honest pricing: vendors inflate projected CI savings to optimize sign-ups; there's no sponsor here, no funnel to upsell into a $5K/mo CI consulting retainer. If the audit doesn't find at least $79/mo in your billing, refund. If you implement the fixes and the bill doesn't drop, refund. The 30-day re-audit voucher is structural accountability, not marketing copy.

FAQ

Do you need access to my GitHub Actions billing dashboard?: No. Static analysis of .github/workflows/*.yml + Dockerfiles only. You generate a fine-grained PAT scoped to contents: read on a single repo, we clone the repo with git clone --depth=1, run the analysis, discard the clone. No billing API, no telemetry, no GitHub App install.
How are you estimating $/mo if you can't see my actual billing?: We estimate using commits/month × workflow trigger fan-out × measured runner minutes per job × current GHA per-minute pricing. The estimate is calibrated against the 30+ public OSS repos we used to validate the rules. The report includes a "calibration confidence" field per finding (95%+ for cache misses, 80%+ for matrix bloat, lower for cron pattern). The 30-day re-audit voucher is the ground-truth check — if your real bill didn't drop by $79+, full refund.
What if my repo is private?: You generate a fine-grained personal access token (PAT) scoped to contents: read on the single repo. Add it to the intake form. We clone, analyze, delete. The PAT can be revoked the second you receive the report.
Do you support GitLab CI / CircleCI / Jenkins?: v1 supports GitHub Actions only. If your repo is on GitLab or CircleCI, refund. GitLab CI v2 is on the roadmap — email if you want priority.
What if my workflows are split across many repos (monorepo vs polyrepo)?: One audit = one repo. If you have 5 repos, that's 5 audits — but email us first; we offer bundle pricing ($59/repo for 5+ repos in the same org).
What if you don't find $79 of savings?: Refund. The 30-day re-audit voucher is a structural accountability layer: implement the fixes, prove the savings didn't materialize, refund. We've designed the product so it's only profitable if the rules actually work.
How is this different from BuildJet / Depot / Namespace / RunsOn?: Those are runner replacement products — you migrate to their infra and pay them instead of GitHub. Ours is a workflow optimization product — keep your existing GitHub-hosted runners, just stop burning minutes. The two are complementary; many customers do both.
What about Actions usage on self-hosted runners?: If you're 100% self-hosted, most cost-leak patterns still apply (matrix bloat wastes your own compute, missing cache slows builds), but the $/mo figure is replaced with "minutes/mo wasted." Email us for a self-hosted-only audit if that's your situation.
