So cool, thanks for sharing. Do you think it might be easier to maintain than something like `act` over the long run?

Love the observability you’ve built into it. But push a little bit further the scale and you’ll probably hit limits with the persistent self hosted runner approach, and end up with something like runs-on (runs-on.com)

> You know how I know GitHub’s runners are bad? Because there’s an entire cottage industry of companies whose sole product is “GitHub Actions, but the runners don’t suck.” Namespace, Blacksmith, Actuated, Runs-on, BuildJet

He's not wrong. Buildjet just announced they were shutting down though, citing recent improvements to the GitHub Actions platform.

For the record I maintain the Runs-on [1] he's talking about, as a solo developer.

Not fully OSS, but you can have a look at https://github.com/runs-on/runs-on

Thanks for posting this :) runs-on.com domain posts never get traction, wonder if this could be due to YCombinator investment in 5+ startups in that space... Oh well.

I am developing a self-hosted solution for this [1]. It’s true that it’s somewhat of a pain but JIT runners allow a lot of flexibility that we don’t find elsewhere.

Probably long overdue, but per-minute price vs per-job is quite expensive. Wouldn’t like to be in the shoes of “only” 2x cheaper third parties. If they follow up with faster runners… interested to see if they ever come up with a good SDK for their scale set API, will integrate it in RunsOn!

But you can self-host github actions runners as well.

crohr — Wed, 23 Jul 2025 16:35:08 +0000

It is not transparent though, so it doesn't work with all the other actions that use the cache toolkit, and you have to reference a specific action.

Also note this open-source project that shows a way to implement this: https://github.com/falcondev-oss/github-actions-cache-server

At this point this is considered a baseline feature of every good GitHub Actions third-party provider, but nice to see the write-up and solution they came up with!

Note that GitHub Actions Cache v2 is actually very good in terms of download/upload speed right now, when running from GitHub managed runners. The low speed Blacksmith was seeing before is just due to their slow (Hetzner?) network.

I benchmarked most providers (I maintain RunsOn) with regards to their cache performance here: https://runs-on.com/benchmarks/github-actions-cache-performa...

FYI you can also use a local S3 bucket as cache backend, and get 5x faster bandwidth and unlimited storage compared to a runner managed by GitHub: https://github.com/runs-on/cache

What kind of CI runners do you use then? Do you self-host?

crohr — Mon, 19 May 2025 07:38:48 +0000

I think if you want this submission to work, you really need to work on your getting started guide. Currently it just says: "Clone the repo".

With Forge, how long does it take to start a runner once everything is setup?

I guess TL;DR just use ephemeral runners when self hosting? There are lots of solutions for that. Also would be nice for GitHub to do something on the security front (allowlist / blocklists if IPs, hosted, etc or at least just reporting on traffic)
