Let's match open source projects that need help with developers looking to contribute. Think of this as "Who's Hiring" but for open source - a monthly thread to surface interesting projects that could use more hands.
Please include: Project name and description (if not widely known); Tech stack; Areas needing help (DOCS, CODE, DESIGN, etc.); Level (BEGINNER-FRIENDLY if applicable); Email address or other means of contacting you.
Ground rules:
Post only if you maintain/run the project
One post per project/suite
No commercial recruitment
No thread complaints
Developers: Only reach out if you actually want to contribute.
