Hi everyone! 👋

Amazing to see so many ideas from the community.

Personally, I went for the Maintainers Must Haves category with workflows that use a recipe to help out maintainers triage and work with external contributions, see it here:

I learned quite a bunch of things about GitHub Actions myself, and definitely new workflows that I'm going to adopt for my own open source repositories.

Goodluck everyone and keep on posting your ideas 🚀

Hi all! I'm working on a GitHub action to bulk merge/approve GitHub pull requests (depending on a valid set of status checks) I'd love any and all feedback 😉

What do you do with issues with dozens of comments? Close it or convert it to discussion?

I don't have an advice, but I've made an action to grab the most reacted comments in a long-winded issue, turn them into clickable elements, then insert them into the issue body.


Hope this will make your open source management a little bit easier.

Just posted my submission for #actionhackathon21

Its a collection of tweaked customized versions of existing workflows from the marketplace that I've been using in a BIG opensource repository with 6000+ contributors, 1k stars & 1.7k forks.
It makes moderation convenient, less chaotic & project management way more smooth...

"More power to the contributors, even more power to the maintainers"

Feel free to leave your feedback/reactions/suggestions to additional features there...
💖 Thanks 🤍

Hi! Just here to share my project :)

Using GitHub Actions to turn contributors into heros of my open source game

I used GitHub's API to get the info from each PR after it's merged. Then the workflow generates a file with the contributors avatar, username, etc. This file is included in the game before the build. Then it's all build and deployed to GitHub Pages!

The workflow also keeps an archive with all previous contributions so you can see yours even after a new PR is merged.

I had so much fun with this :D

Hey everyone 👋 How about having your favorite song on the collaborative playlist of all developers?

All you need is a simple issue on the Developers' Playlist repository:

GitHub logo oz9un / Developers-Playlist

A drop of musical taste from every contributor... Welcome to the developer's collaborative playlist.

Developers' Playlist \(📀_💿)/

A drop of musical taste from every contributor... Welcome to the developers' collaborative playlist.

Playlist link: Developers' Collaborative Playlist


The same algorithm can be written differently by each developer. The developer's code style becomes their signature.

Coding is an art, so what do artists listen to while performing this art?

The Developer's Playlist analyzes opened issues on this repository using GitHub Actions and collects developers' favorite songs into a collaborative playlist.


  • Open an issue with title 'song request' ( 'Song request' and 'Song Request' also works right now.)
  • Write your favorite track to issue's body in format: "artist-song". ( If there is a dash "-" in the artist or song title, please use space instead for now. )
  • Wait for the Github Action Bot's response
  • Enjoy the developers' collaborative playlist!
  • You…

Hey I've made an action that at at least i find very useful 🙂 It's called terraform_state_artifact and stores your Terraform statefile as an encrypted GitHub workflow artifact 🚀
