GitHub Actions vs CircleCI: pick GitHub Actions if your code is on GitHub and your pipelines are ordinary. At 20 engineers it's cheaper up to at least 30,000 build minutes a month, and there's one less vendor. Beyond that the two bills stay within a few hundred dollars, far less than a DevOps engineer's time. Pick CircleCI if you run several code hosts, or queues and test splitting are the real problem.
Which one fits your team?
GitHub Actions
It's the CI built into GitHub, billed with your GitHub plan. The pipeline sits next to the pull request, there's no second login, and some compute is already in the plan. The catch is that it only works with code hosted on GitHub, and heavy users pay per minute once the included dollars run out.
GitHub's billing docs price a hosted Linux 2-core runner at $0.006 a minute. macOS costs $0.062, roughly ten times that, so mobile teams feel the bill first. Included compute is stated in dollars, not minutes. Team's $18 works out to about 3,000 Linux minutes, which matches the pricing page, and Free's $12 to about 2,000.
CircleCI
CircleCI is a standalone CI vendor that connects to GitHub, GitLab and Bitbucket. Teams pick it when builds are slow or queued, or when repos aren't all on one host. The catch is the credit model and the second bill: you pay for seats and for credits.
CircleCI's pricing page lists Free at $0 with 30,000 credits and 5 users. Performance starts at $15 with the same allowance, then charges $15 per 25,000 extra credits and $15 a month per extra user. A Linux medium job burns 10 credits a minute, so the included credits cover 3,000 minutes. CircleCI also says a minute on its platform isn't the same as a minute elsewhere, so compare cost per finished build, not per minute.
What a 20-engineer team pays at list prices
At list prices on 1 November 2026, a 20-engineer team on GitHub Team and CircleCI Performance pays this a month, with GitHub builds on Linux 2-core and CircleCI builds on Linux medium.
| Build minutes a month | GitHub Team | CircleCI Performance |
|---|---|---|
| 3,000 | $80 | $240 |
| 10,000 | $122 | $240-285 |
| 50,000 | $362 | $300-525 |
GitHub's figure is 20 seats at $4 plus $0.006 for each minute above the 3,000 included. CircleCI's $240 is the $15 plan plus $225 for the 15 users beyond five, before any credit packs.
The CircleCI ranges exist because its pricing page can be read two ways: either extra users bring 25,000 credits each, or they don't. The low end of each range assumes they do, the high end assumes they don't. Ask CircleCI which reading your quote uses.
Seats are why CircleCI looks expensive at low volume. Build minutes take over from roughly 10,000 a month. Under the generous reading CircleCI overtakes GitHub on price at about 30,000 minutes; under the strict one GitHub stays cheaper at every volume in the table.
Self-hosted runners
Running your own machines is the usual way to escape per-minute bills. GitHub's docs say self-hosted runners are free to use, and you pay for the hardware. Its changelog announced a $0.002 per minute platform charge for them from 1 March 2026, then postponed it with no new date. If self-hosted is your plan, budget for that charge coming back. CircleCI charges nothing per minute on self-hosted runners, only 420 credits per GB of network and storage beyond the plan's allowance.
Concurrency and speed
CircleCI's pricing page is the one that quantifies queueing: 30 concurrent jobs on Free and 80 on Performance. We'd expect a 20-engineer team opening a pull request every few minutes to rarely hit 80. Speed claims are another matter. CircleCI's comparison page markets its platform as delivering build times up to 40% faster than GitHub's own compute, and that's a vendor claim, not an independent test. Time your slowest pipeline on both before you believe any percentage.
Security and migration
Both vendors store your deploy keys and cloud credentials, so the real risk is what's inside the pipeline. The choice of vendor matters less than short-lived tokens, scoped secrets and a rotation plan you've actually rehearsed. Our CI agent privilege escalation checklist is the audit to run whichever you pick.
Moving CI is a project, not an invoice swap. Every config, secret, cache and deploy hook gets rewritten, and someone has to babysit the cutover. Ask the engineer who owns your pipeline for an estimate before a monthly saving tempts you. Staying on GitHub Actions has its own upkeep: runtimes get retired, and fixing workflows after the Node 20 removal is the kind of chore someone has to own.
When each wins
Choose GitHub Actions if the code is on GitHub, builds are standard and nobody on the team owns pipelines full time. We'd put most product teams under 50 engineers here.
Choose CircleCI if you have repos on more than one host, you need test splitting or layer caching to keep builds short, or queues already cost you developer hours. Running both is a cost, not a plan.
What this means for your CI budget and DevOps capacity
Decide on two things: the table above at your own headcount and build volume, and who owns the pipelines. The invoice gap is small next to the salary of the person who maintains the pipeline, so the tool that needs less of their time wins. That's usually the one already attached to your repos.
If nobody owns CI today, settle that before you compare vendors. A slow, flaky pipeline on the cheaper tool costs more than a fast one on the dearer tool.
Budgeting the people around the tool is the next step: what a software team costs in Europe shows where a DevOps hire fits. Other stack decisions are covered in Hire developers by tech stack: rates, vetting and interview guides.
Hiring a DevOps engineer through HighCircl
Whichever tool you choose, the pipelines need an owner, and so does the migration if you switch. That person handles the runners, the token audit and the build minutes you've just priced. HighCircl matches you with senior DevOps engineers in 72 hours, at €45-105/hr ($50-115/hr). If you'd rather not add a permanent role yet, a contract engineer can run the migration and hand the pipelines back.
FAQ
Is GitHub Actions enough for CI/CD?
For most product teams on GitHub, yes. It builds, tests and deploys from the same repo, and the plan includes compute. Look at CircleCI when queue time or multiple code hosts become the problem.
What is the pricing difference between GitHub Actions and CircleCI?
GitHub charges per minute against dollars included in your plan, plus $4 per user on Team. CircleCI charges credits plus seats. At 20 engineers and 10,000 minutes a month, that's $122 against $240-285.
Does GitHub charge for self-hosted runners?
Not today. GitHub announced a $0.002 per minute charge from 1 March 2026 and postponed it without a new date.
Which has the better free tier?
CircleCI Free gives 30,000 credits, which CircleCI says covers up to 6,000 minutes on its smallest Docker class. GitHub Free includes about 2,000 minutes on a Linux runner. CircleCI's allowance is larger on paper, but its minutes aren't GitHub's minutes.
Can I use CircleCI with GitHub?
Yes. CircleCI's version control docs list GitHub, GitLab and Bitbucket among the code hosts it connects to.
