r/opensource
Projects released under an approved open-source license, and the people who maintain them, are the focus of r/opensource. Requests for open alternatives to commercial apps sit beside licensing discussions and threads on maintainer burnout and funding. Several guides say projects are welcome, and one adds detail: use the 'Promotional' flair, link a repository with an OSI-approved license file, and avoid AI-generated text, which is reportedly treated as grounds for a ban. That last point matters for anyone using drafting tools; every reply should be rewritten by a person. Source-available or closed products do not belong, and paid hosted editions or open-core splits should be named up front.

Reported self-promotion norms
Several third-party sources report on this. Open-source projects are welcome under rules. One guide (updated 2026-10-07) says to use the 'Promotional' flair, that linked repos must carry an OSI-approved LICENSE file, that drive-by posts are removed, that AI-generated content is treated as ban-worthy, and that it follows Reddit's under-10% self-promotion guideline. Another guide says promotion is fully allowed for open-source projects with a GitHub link. Two more say open-source projects get more leeway or that the sub exists to discover new projects.
