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 conditionsYes, 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-friendlyYes, 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 conditionsYes, 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 conditionsYes, 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.
Participate first, promote rarely
Promotion here is heavily restricted or the rules leave it unstated. Build a presence by being useful; an occasional relevant mention may survive, a pitch will not.
r/Notion 465.5K members · ~17 posts/day
Strictly limitedYou cannot promote your product in the main feed of r/Notion. Rule 4, "No self-promotion," says, "Self-promotional and showcase content is only allowed in the fortnightly pinned Self-promo & Showcase threads," including "free and paid templates, third-party integrations, and dashboard showcases."
r/ObsidianMD 347.6K members · ~31 posts/day
Strictly limitedPromotion is heavily restricted. Rule 3 says, "Don’t shill" and adds, "If you are just here to advertise your product, don’t." Rule 4 also says, "If your first and only post is to promote your project (vibe-coded or otherwise), you will be immediately banned," so you should not use this subreddit mainly as an advertising channel.
r/SomebodyMakeThis 95.3K members · ~3 posts/day
Strictly limitedYou generally cannot promote your product in r/SomebodyMakeThis. Rule 2, "No Promotions," says posts promoting "Products, Ideas, or Platforms" for selling or enrolling users are not permitted, and it only allows certain promotions inside a pinned thread in the Highlights section. The public description also says, "Did you create something? Share it with us in the monthly Creator Showcase thread!"
Don't promote here
These communities ban promotion outright. Still worth being present as a genuine participant: buyers read these threads, and so do the AI models answering their questions.
r/productivity 4.2M members · ~16 posts/day
Promotion bannedNo, you cannot promote your product in r/productivity. The rules explicitly say "No Advertising" and "Self-promotion is not allowed here in any form," and they also include DM advertising, referral codes, soliciting, surveying, and promotional/link farming as violations.
r/WorkOnline 758.5K members · ~1 posts/day
Promotion bannedNo, you cannot promote your product in r/WorkOnline. The sidebar states, "This sub is NOT for self-promotion. Posts advertising yourself for hire will be removed without hesitation," and also says, "No external/self-promotional business links and blogs."
r/androidapps 566.3K members · ~25 posts/day
Promotion bannedNo. Rule 2, "Self-Promotion & Dev Content," says, "Any self-promotion, tester requests, new app ideas or app feedback are not allowed in r/androidapps." The same rule says this content should go to the sister subreddit r/droidappshowcase instead.
