Verified member counts, real self-promotion rules, and what actually converts in each community. No fluff, no stale numbers.
r/SaaS, r/IndieHackers, and r/SideProject are the strongest starting point for most SaaS founders. All three explicitly allow self-promotion when it is framed as a build-in-public story, a launch, or a genuine feedback request, and their audiences are already SaaS-literate. Larger subreddits like r/Entrepreneur and r/startups reach more people but demand a much stronger story before a post survives.
One thing worth saying plainly: not every subreddit on this list wants a product pitch. Roughly a third of the 18 either ban direct self-promotion outright (r/Sales, r/programming) or confine it to a single weekly thread (r/webdev's Showoff Saturday, r/EtsySellers' Milestone thread). Posting the wrong way in the wrong community is the fastest way to get removed or banned, so the tier breakdown further down this page matters as much as the ranking itself.

MediaFast turns your product description into a ranked subreddit list with rules and conversion tips for each community, in about 30 seconds.
All 18 subreddits fall into one of three tiers. Treating a Tier 3 community like a Tier 1 one is the fastest way to get a post removed or an account banned.
Tier 1, story-friendly (direct promo allowed with the right framing)
These communities allow a product mention if it reads as a genuine story, launch, or milestone rather than an ad.
r/SaaS, r/Entrepreneur, r/IndieHackers, r/SideProject, r/EntrepreneurRideAlong, r/B2BSaaS, r/microsaas, r/Shopify, r/PPC
Tier 2, designated-thread only
Promotion is allowed, but only inside one specific recurring thread. A standalone post gets removed regardless of quality.
r/webdev (Showoff Saturday megathread), r/EtsySellers (stickied weekly Milestone and Self-Promotion thread)
Tier 3, answer-only or banned outright
No direct promotion. Treat these as audiences to serve with genuinely useful answers, mentioning your product only when it is the honest answer to someone's question.
r/startups, r/smallbusiness, r/marketing, r/Sales, r/devops, r/programming, r/HENRYfinance
Reach is not the goal, relevance is. A decision tree beats a gut feeling here.
If your SaaS is a horizontal tool used by any founder
Start with r/SaaS, r/IndieHackers, and r/SideProject. These audiences buy and try tools constantly and reward a clear build-in-public story.
If your SaaS serves a specific vertical (dev tools, ecommerce, sales, finance)
Go directly to the niche subreddit for that buyer, r/devops, r/webdev, r/Shopify, r/EtsySellers, r/Sales, or r/HENRYfinance. A 26,000-member niche audience converts better than a 5-million-member general one when the fit is right.
If you are very early and want feedback more than signups
r/SideProject and r/IndieHackers are built for this. Post the rough version and ask directly for critique, this also builds karma before you try a harder subreddit.
If the subreddit bans self-promotion outright
Do not post your product. Spend time answering questions genuinely (r/Sales, r/programming, r/HENRYfinance). Visibility through helpfulness compounds even without a single promotional post.
None of these 18 subreddits ban SaaS founders as a category. They ban these specific behaviors.
This is the single clearest spam signal Reddit's filters look for. Stagger crossposts by at least 30 to 60 minutes and rewrite the framing for each community.
Most of these subreddits either require or informally expect an account with some age and karma. Spend two to four weeks commenting genuinely before your first promotional post.
A post that works in r/SaaS gets removed in r/programming. Match the framing (story, case study, or answer) to the tier that subreddit falls into, covered below.
A post with 15 upvotes in r/B2BSaaS that lands three demo calls beats a post with 400 upvotes in r/Entrepreneur that lands none. Track signups and demo requests, not karma.
r/Sales, r/HENRYfinance, and similar communities ban direct promotion, but they are still worth reading and answering questions in if your buyer lives there.
r/webdev and r/EtsySellers do allow promotion, just not as a standalone post. A launch post outside the Showoff Saturday or Milestone thread gets removed regardless of quality.
Cadence depends on the tier, not on how much progress you have made. Posting more often than a subreddit's norm reads as spam even when every individual post is high quality.
| Tier | Safe cadence | Why |
|---|---|---|
| Tier 1, story-friendly | Every 3 to 4 weeks per subreddit | Enough time for a new milestone or lesson to justify a fresh post, and for the last one to clear the front page. |
| Tier 2, designated-thread | Whenever that week's thread goes up | Cadence is fixed by the subreddit itself, r/webdev's Showoff Saturday and r/EtsySellers' Milestone thread run weekly. |
| Tier 3, answer-only | No fixed cadence, mention only when relevant | There is no promotional post to schedule, the cadence is however often you can genuinely answer a question your product solves. |
This is the order most successful SaaS launches on this list actually followed, not a theoretical checklist.
3 to 4 weeks before launch
Create or warm up an account in your target subreddits. Comment genuinely, answer a few questions, build real karma.
1 week before launch
Read the current rules and pinned posts of each Tier 1 subreddit you plan to post in, rules change more often than founders expect.
Launch day, morning
Post in r/SideProject or r/IndieHackers first, these are the most forgiving of a rough first version and the feedback improves your framing.
Launch day, 2 to 3 hours later
Post in r/SaaS with an updated framing based on the feedback from the first post.
Launch day, evening
If it fits, post in one niche subreddit for your vertical, r/devops, r/Shopify, or r/B2BSaaS, with a version tailored to that audience's specific problem.
Week 1 after launch
Answer every comment personally, this drives more signups than the original post in most cases.
Week 3 to 4 after launch
Post a follow-up with real numbers, users gained, revenue, or a lesson learned, in the same Tier 1 subreddits.
Ongoing
Stay active in the Tier 3 subreddits your buyers read, answering questions, so your product comes up naturally when someone asks for a recommendation.

This page ranks and scores the 18 communities by verified size, self-promotion tier, and what actually converts, which is a different lens than a categorized subreddit directory. If you want subreddits grouped by primary versus niche versus avoid instead of ranked, MediaFast's directory of subreddits to promote your SaaS covers that angle.
Eighteen general subreddits will only ever be a starting point. Tools like MediaFast can generate a list matched to your specific product description in about 30 seconds, which catches the smaller, hyper-relevant subreddits a generic list like this one cannot cover for every possible SaaS category.
Sharing the process of building a SaaS in real time, revenue, user counts, and setbacks included, rather than only announcing a finished product. This framing is what makes Tier 1 subreddits tolerate self-promotion.
A recurring, pinned thread (weekly or otherwise) that is the only place a subreddit allows product links. r/webdev's Showoff Saturday and r/EtsySellers' Milestone thread are examples.
An informal Reddit-wide norm suggesting no more than 1 in every 10 posts or comments should be self-promotional, with the other 9 being genuine, non-promotional participation.
A minimum combined post and comment score some subreddits' automod enforces before allowing a link post. Several Tier 3 subreddits on this list remove low-karma link posts automatically.
A community where direct product posts are not allowed, but mentioning a product inside a genuinely helpful answer to someone else's question is tolerated.
This page's own classification of each subreddit's self-promotion policy, story-friendly, designated-thread, or answer-only, based on each community's stated rules.
Answers to what founders actually ask before posting.
r/SaaS, r/SideProject, and r/IndieHackers are the strongest launch trio for indie SaaS. All three allow promotional content when it is framed as a build-in-public story or a genuine feedback request rather than a bare product link.
Yes, but the bar is high. With over 5 million members the subreddit is saturated, so a plain pitch gets buried fast. You need a strong hook, real numbers, and a story format that leads with the struggle before the product.
Often yes. A 26,000-member subreddit like r/B2BSaaS can convert better than a 5-million-member general one because the audience is self-selecting and already interested in exactly what you sell. Specificity tends to beat raw reach.
It depends entirely on the subreddit. A 2026 OneUp Today study of subreddits founders commonly pitch in found that 61% ban self-promotion outright or restrict it to a designated thread. r/Sales and r/programming ban it outright, r/webdev and r/EtsySellers confine it to a weekly thread, and r/SaaS or r/microsaas allow it directly if framed as a story.
Space updates at least three to four weeks apart and always add new information, a revenue milestone, a feature launch, or a lesson learned. Reposting the same pitch weekly reads as spam even in the most promo-friendly subreddits on this list.
Look at where your existing customers already spend time online, then check each subreddit's rules before posting. Tools like MediaFast can generate this list automatically from a plain product description, which saves the manual research this guide had to do by hand.
