Reg. hiking it again, they'd have to either be extremely anti-competitive and selectively apply the pricing OR apply the hike uniformly by about double the current value to match our pricing while making it completely unviable for any large co to use self-hosted github actions in the first place.

Without GitHub's free CI for public repos, the small projects and indies will get hit the hardest imo.

However, I do not know hard numbers to quantify the impact.

Overall costs go up for everyone but we remain the better option.

1. Self-hosting runners or using WarpBuild/blacksmith runners is still cheaper Despite the $0.002/minute self-hosted runner tax, self-hosting runners on your cloud (aws/gcp/azure/...) or using WarpBuild/... runners remains the cheaper option.

2. Prefer larger runners If your workflow scales with the number of vCPUs, prefer larger runners. That ensures you spend fewer minutes on the runner, which reduces the GitHub self-hosted runner tax.

For example, using actions-runner-controller with heavy jobs running on 1 vcpu runners is not a good idea. Instead, prefer a 2vcpu runner (say) if it runs the job ~2x faster.

3. Prefer faster runners All else being equal, prefer faster runners. That ensures you spend fewer minutes on the runner, which reduces the GitHub self-hosted runner tax.

For example, if you're self-hosting on aws and using a t3g.medium runner, it's better to use a t4g.medium runner since the newer generation is faster, but not much more expensive.

4. Prefer fewer shards If you have a lot of shards for your jobs (example: tests on ~50 shards), consider reducing the number of shards and parallelizing the tests on fewer but larger runners.

5. Improve job performance This is not new advice, but it's now more important than ever because of the additional GitHub self-hosted runner tax.

6. Use GitHub hosted runners for very short jobs For linters and other very short jobs, it's better to use GitHub hosted runners.

Hope this helps. Note: I'm the founder of WarpBuild. I'm biased, but the points above hold.

Performance is the primary lever to pay less $0.002/min self hosting tax and we strive to provide the best performance runners.

1. Services like blacksmith and WarpBuild (I'm the founder) are still cheaper than GitHub hosted runners, even after including the $0.002/min self-hosting tax.

2. The biggest lever for controlling costs now is reducing the number of minutes used in CI. Given how slow Github's runners are, or even the ones on AWS compared to our baremetal processor single core performance + nvme disks, it makes even more sense to use WarpBuild. This actually makes a better case for moving from slow AWS instances running with actions-runner-controller etc. to WarpBuild!

3. Messaging this to most users is harder since the first reaction is that Github options make more sense. After some rational thought, it is the opposite.

Overall - it is worse for Github users, but options like blacksmith and WarpBuild are still the better option.

Given that GitHub runners are still slow as ever, it actually is a point in our favor even compared to self-hosting on aws etc. However, it makes the value harder to communicate .

Given github ran 11.5 billion mins of actions in 2025, and most of them would've been on self-hosted runners, this move makes some sense from their POV.

However, this is still an... interesting... move, especially after bitbucket got all that hate a few weeks ago for doing something similar.

Note: I make WarpBuild, where we provide github actions runner compute. Our compute is still cheaper than using github hosted runners (even with the $0.002/min tax) and our runners are optimized for high performance to minimize the number of mins consumed. I'm generally biased, but I think the points 1-6 apply irrespective of WarpBuild.

If you're building multi arch images, here is a page that may be useful: https://docs.warpbuild.com/docker-builders#multi-platform-bu...

We natively support multi platform builds in our drop in replacement action.

It essentially makes a copy of your entire state of the runner, which you can then use in subsequent runs, with no concurrency limits.

This essentially automates out a lot of the work you're doing to make the jobs faster.

We provide a product similar to Blacksmith.
