Best Subreddits to Promote a Productivity App

Productivity subreddits are unusually open to app recommendations because the whole topic is tooling. Tool-specific subs (Notion, Obsidian) welcome ecosystem products but police generic promotion.

10 communities, 8.3M combined members, ranked by each subreddit's own rules.

Where promotion is tolerated (with care)

These communities allow product mentions under their stated conditions. Read the linked rules before posting, the conditions are specific.

r/selfhosted 806.7K members · ~46 posts/day

Allowed with conditions

Yes, but only within clear limits. Rule 2, "Spam / Self-Promotion / Affiliate Links," says, "Do not spam or promote your own projects too much," requires following Reddit's self-promotion guideline, and adds that promoted apps "must be production ready and have docs." There are also narrower exceptions, such as Rule 6 allowing very new projects only in the current "New Project Megathread," and Rule 4 requiring explanation for blog link posts.

r/SideProject 787.5K members · ~270 posts/day

Promo-friendly

Yes, you can promote your project in r/SideProject, because the community description and sidebar explicitly say it is for sharing side projects and receiving constructive feedback. The stated requirement is the submission format: "When submitting a link to a project or startup, please use this format: [Project name] - [Short description]."

r/macapps 240.6K members · ~9 posts/day

Allowed with conditions

Yes, but only under specific conditions. Rule 3, "Limited Self-Promotion," says self-promotion is allowed only infrequently, "not permitted more than once per developer in 30 days," and Rule 8, "Promote in Megathread," says anyone who does not qualify for main feed promotion must use the monthly Megathread. Rule 1 also says app devs have "No main feed promotion unless you qualify" and must use the PCP Post template.

r/alphaandbetausers 40.1K members · ~86 posts/day

Allowed with conditions

Yes, you can promote your product in r/alphaandbetausers, but only if it fits the subreddit’s testing purpose and follows the posting rules. Posts must include a link to a product that is ready to be tested, use stage and system tags, include a description, and must not be just an email signup, launch waitlist, or future testing application page; spam, non-alpha/beta links, and NSFW products can be removed.

Rankings come from each subreddit's own published rules (quoted on the linked pages), not opinion. And whatever the rules allow on paper, the removal pattern everywhere is the same: batches of similar comments, reused wording, and necro-posting die. We measured it: 80% of bought Reddit comments were removed within a month.
