Why Reddit Works
Open source lives and dies by community, and Reddit is where developers go to discover new tools organically. Unlike Hacker News where your post disappears in hours, a well-received Reddit post in r/programming or r/selfhosted keeps driving GitHub stars for weeks. Reddit developers actively look for projects to contribute to — they just need to understand why your project matters and how they can help.
The README sells the project, but the Reddit post sells the story. Open source adoption starts with empathy for the problem.

Pro tip: Include a 'good first issues' callout in your Reddit post. Developers reading your launch post are in peak curiosity mode — give them a low-friction way to contribute immediately while the motivation is fresh.
Posting Strategy
🎯
Choose the right language community
Post in the subreddit for your project's primary language (r/rust, r/python, etc.) in addition to general programming subs. Language communities have the highest contributor conversion rates.
📝
Show a real-world use case
Don't just explain what your library does — show the exact code snippet that solves a real problem. A compelling before/after code comparison is irresistible to developers.
⏰
Prepare your repo for visitors
Before posting, ensure your README has a quick-start section, your issues are labeled, and your CI is green. Reddit developers will judge your project's health in under 30 seconds.
A GitHub repo with 10 stars and a great Reddit launch story will outperform a 1,000-star repo that nobody understands.

I open-sourced a CLI tool that migrates any database schema to any other database — PostgreSQL, MySQL, SQLite, and MongoDB
I've been working on this for 8 months after our team had to migrate from MySQL to Postgres and every existing tool broke on our edge cases. It handles custom types, stored procedures, and even translates vendor-specific SQL. It's a single binary with zero dependencies. MIT licensed, works on Linux, Mac, and Windows. I've tagged a bunch of 'good first issues' if anyone wants to contribute. Honest feedback on the API design would be incredibly helpful.
