Ask HN: Alternatives to GH Actions?

Looks like Github actions are having an outage again: https://www.githubstatus.com/

We already use blacksmith to not use Github Runners. Highly recommend it if you haven't tried it yet. But we still rely on Github to actually trigger the workflow. With all their constant outages, I was wondering if there are alternatives available? Moving to Gitlab is quite a big migration, so I was wondering if there are ways to mitigate this for now and not relying on GitHub actions to trigger workflows periodically and on actions (eg. on merging to main)?
