A ranked table of 20+ subreddits with post frequency caps, link rules, and mention requirements. Plus a 4-bucket categorization and a decision tree by product type. For the biggest one on this list, see our r/SideProject marketing playbook.
Self-promotion is the point of the sub. No fixed posting day, but disclose you built it.
One SHOW IH flaired post per product, framed as a request for feedback, not a launch ad.
Journey and progress posts with real numbers are tolerated. Straight pitches get removed.
Built for exactly this. Tag [Alpha] or [Beta], one post per product per month.
Allowed if you genuinely built it and explain how. No dropshipping or affiliate links.
Verified against live subreddit rules trackers in August 2026. Rules change, so confirm against the subreddit's own pinned rules before posting. Full sourcing in the table below.
Six subreddits explicitly allow self-promotion: r/SideProject, r/indiehackers, r/EntrepreneurRideAlong, r/GrowthHacking, r/AlphaandBetaUsers, and r/IMadeThis. All require founder disclosure, but accept direct links and product-forward posts. They are your first targets.
Eight more subreddits accept conditional promotion in lesson or case-study format. The remaining 20+ large communities ban product promotion outright. Knowing which bucket a community sits in before you post is the difference between building a presence and getting banned. MediaFast maps your product to the right communities automatically.
Before reading a subreddit's full rules, these four categories tell you what kind of post is safe.
Explicitly welcoming founder posts with direct product links. Little or no warmup required. Disclosure is still mandatory.
Allow promotion only in specific formats: case studies, lessons, feedback requests. Pitch language gets removed. Story language survives.
Technical or news-only communities. Third-party coverage or open-source code required. Self-promotion language triggers mod removal.
Zero tolerance communities. Product links are auto-removed. Any mention, even subtle, gets flagged. Do not post here.

The bucket system above is built from observed community behavior, but the underlying ratio and disclosure rules trace back to Reddit's own Content Policy and Help Center, not just forum folklore. Each fact below links to the live source.
9:1 ratio
is Reddit's own guidance on how much of your activity can be promotional
Reddit's Help Center states it plainly: only 1 out of every 10 of your submissions should be your own content. Contributions consisting primarily of links to a business you run, own, or benefit from should be posted thoughtfully, or run through Reddit's self-serve ad platform instead.

Content Policy Rule 1
requires "authentic content," not promotional content in disguise
Reddit's Content Policy opens by requiring users to post authentic content into communities where they have a genuine interest, and to not engage in content manipulation. A promo post dressed up as a question or a story is exactly what this rule targets.
View the sourceReddit, Content Policy
No sitewide promo ban
self-promotion is not spam by default, per Reddit's own rules
Reddit's spam guidance is explicit that promotional content is not inherently considered spam. What tips it into spam is frequency, repetition, and whether the account exists only to push links. Community-specific rules can still be stricter than the platform baseline.
View the sourceReddit Help Center, "What constitutes spam? Am I a spammer?"
"Post authentic content into communities where you have a personal interest, and do not cheat or engage in content manipulation (including spamming, vote manipulation, ban evasion, or subscriber fraud)."
Reddit, Content Policy, Rule 1
A compact reference you can scan in one pass. Each rule was cross-checked against multiple current subreddit-rules trackers, with a link to the subreddit's own live rules page for the final word.
| Subreddit | Current Rule | Best Format |
|---|---|---|
| r/SideProject | Self-promotion is the stated purpose. Project-context posts allowed most days. | Launch or build-in-public update |
| r/indiehackers | One SHOW IH flaired post per product, judged on feedback intent, not ad intent. | Ask for feedback, not traffic |
| r/EntrepreneurRideAlong | Case-study and journey posts with metrics are tolerated over raw pitches. | Progress update with real numbers |
| r/AlphaandBetaUsers | Purpose-built for beta requests. One post per product per month. | Beta signup ask with a clear scope |
| r/IMadeThis | Allowed if you built it yourself and explain the process. | "I made this" plus how it works |
| r/startups | Direct promo posts outside the designated share-your-startup thread are removed. | Use the dedicated thread only |
| r/SaaS | Restricted to posts framed as feedback requests, not launch announcements. | "Would love feedback on..." post |
Sources cross-referenced in August 2026: each subreddit's own live rules page (linked above), the OneUp Today self-promotion rules database, the Soar Agency self-promotion rules database, and gofindevo.com's r/indiehackers rules breakdown. Before your first post in any of these, run your account through the free Reddit CQS Checker so you know whether AutoMod is likely to auto-remove your post regardless of which subreddit you pick.
MediaFast tracked 10,000 Reddit posts submitted by its own users between January and May 2026, recording the exact post timestamp, upvotes in the first hour, and final score after 24 hours. Tuesday between 7 and 9 AM ET came out as the single best posting window in the dataset, with a 1.8x engagement multiplier over baseline. Posting a fully permitted self-promo post to r/SideProject or r/indiehackers at the wrong hour still buries it.

Answer yes to the first question that fits. Stop there. That is your starting subreddit cluster.
If yes
Start with r/SideProject, r/indiehackers, r/SaaS. These three communities are built for software founders.
If no
Go to question 2.
If yes
r/IMadeThis, r/EntrepreneurRideAlong, and r/GrowthHacking work well. These subs respect the builder ethos.
If no
Go to question 3.
If yes
r/marketing and r/GrowthHacking are your best bets. Data-backed posts earn respect in both.
If no
Go to question 4.
If yes
r/webdev, r/programming (technical posts only), r/devops. The community will evaluate your code, not your pitch.
If no
Go to question 5.
If yes
r/startups, r/Entrepreneur, and r/smallbusiness accept lesson-format posts. Frame around the lesson, not the product.
If no
Keep building until you have something real to share. Posting without a story rarely works.
Eight terms that appear in subreddit rules. Know these before reading any subreddit's policy page.
Any post or comment where you stand to benefit commercially from the response. Reddit's rules use this term broadly. A founder answering a question by recommending their own product counts.
For every 1 promotional post or comment, you should have made at least 9 to 10 non-promotional contributions. Reddit's own Help Center states it directly: only 1 out of every 10 of your submissions should be your own content. Reddit enforces this culturally in most subs, and some subs have it as an explicit written rule.
Some subreddits explicitly limit how often a single account can post promotional content. r/indiehackers has informal norms; others have automod rules that remove posts that match patterns of over-posting.
Many subreddits require specific post flair for certain content types. r/Entrepreneur uses flairs like 'Progress', 'Success/Milestone', and 'Seeking Advice'. Posting a promo under 'Seeking Advice' flair is considered dishonest and gets removed.
An automated moderator script that runs rule-based checks on every post. Common triggers include new accounts, URLs that match domain blacklists, and specific keywords. Posts caught by automod are removed instantly and silently.
Some subs require a minimum amount of link karma (from posts, not comments) before your links are visible. This is different from comment karma. Most founders build enough comment karma but lack sufficient link karma.
Subreddits can restrict which domains are allowed in links. A blacklisted domain means any post linking to that site is auto-removed, regardless of post quality or account age.
Stating openly that you are the creator, founder, or otherwise financially affiliated with what you are posting about. Reddit's Content Policy requires posting "authentic content" in communities where you have a genuine interest. Most communities expect disclosure in the first sentence.
Knowing which subreddits allow promotion is step one. Step two is writing a post that survives in an open community and lands in conditional ones. The pattern across successful founder posts is consistent: the product is the context, not the point. The lesson, number, or story is the point.
Founders who research subreddit norms before posting see 3-4x higher survival rates on their posts. Those who also calibrate tone, which means matching the vocabulary and formality of the top posts in each sub, see meaningfully higher engagement. MediaFast surfaces these norms and drafts posts in the right voice for each community, so the research happens before the post, not after the removal notice.

Lesson-first post where the product is mentioned mid-story
The product should appear as the vehicle for the lesson, not as the destination.

Six questions founders ask before choosing where to post.
r/SideProject is the most permissive. It is purpose-built for founders sharing what they have made. r/indiehackers and r/EntrepreneurRideAlong are close seconds. All three require full founder disclosure but welcome direct links and launch posts. For ongoing updates, r/EntrepreneurRideAlong is uniquely accommodating.
It varies by subreddit. Some, like r/Entrepreneur, have automod rules that filter accounts with very low comment karma or accounts under 30 days old. Others like r/SideProject do not have a strict karma gate but rely on community downvoting to filter low-quality promos. Aim for 200+ comment karma site-wide before any promotional post.
You can, but do not use the same text. Reddit's spam detection flags duplicate content across subreddits, and many users browse multiple subs, so they will notice if you are posting the same launch post everywhere. Write a fresh opening for each sub. Keep the link and product the same, but customize the framing for each community.
The safest universal cap is once per 30 days per subreddit for any promotional content. Many subs have explicit or informal rules around this. r/GrowthHacking enforces roughly one case study per 30 days. r/SaaS follows a similar pattern. Some like r/EntrepreneurRideAlong allow more frequent updates if they are genuinely ongoing, not repetitive.
Yes, and comments are often more effective than posts. When someone asks 'what tool do you use for X', recommending your own product with full disclosure is accepted in most subs. The key is that the recommendation must be relevant and disclosed. Dropping your product link in unrelated threads is spam.
Do not repost immediately. Message the moderators and ask which format would be acceptable. Most mods respond within 24 hours and will tell you whether a lesson-format repost would pass. Reposting without asking usually results in a temporary ban from the subreddit.
MediaFast matches your product to the subreddits that allow your type of content, then drafts posts in each community's voice. No more removals from posting in the wrong bucket.
