Can someone recommend a more stable alternative to GitHub Actions?

One of the things that I love about Github Actions is the experience of having a single user experience for continuous integration and continuous deployment. Last year we switched to Github Actions because of Bitbucket Pipelines instability. Recently Github Actions has been an even worse experience than Bitbucket Pipelines was.

I was wondering if anyone had experience with stable hosted CI/CD offerings that might have a similar experience to Github Actions from a development standpoint with a lot more platform stability.
