The 5 best subreddits for vibe coders shipping in 2026

If you're vibe-coding a SaaS in 2026, the bottleneck isn't shipping code anymore. Claude and Cursor handle that. The bottleneck is finding the four or five places online where the kind of person who'd pay for your thing actually hangs out, and not getting your account nuked the first time you post.

Reddit is one of those places. But "post on Reddit" is useless advice. Each sub has its own rules, its own AutoModerator config, its own opinion of self-promotion, and its own karma gate. Below are the five subs I'd actually open if I were shipping a vibe-coded product this quarter, with the self-promo policy stated up front for each one so you don't get caught.

All rules below were pulled from each subreddit's public rules page and wiki. Subscriber counts come from the public sidebar at the time of writing; check them yourself before you post because they move.

How to read this list

For each sub I'm calling out four things:

• Subscribers — the public sidebar number.
• Self-promo policy — what the rules and wiki actually say about promoting your own work.
• Karma / age gate — what AutoModerator filters on. Often unstated but enforced.
• What works — the post format that doesn't get auto-removed.

Subreddit	Approx. subscribers	Self-promo policy	Best post format
r/SaaS	~370k	Allowed if substantive; weekly promo thread for pure plugs	Build-in-public post with numbers
r/indiehackers	~80k	Allowed, no link-dropping without context	Lessons-learned writeup
r/SideProject	~250k	Built around showing projects	Demo + ask for feedback
r/microsaas	~30k	Allowed, low-tolerance for fluff	Specific metric + how you got it
r/EntrepreneurRideAlong	~280k	Allowed for journey posts, not pure ads	Multi-week update thread

1. r/SaaS

r/SaaS is the biggest concentration of SaaS founders on Reddit and the default first stop. It's also where the bar for "interesting" is highest, because every single day someone else is also posting their MRR screenshot.

• Self-promo policy: Direct self-promo posts get removed unless they include real substance (specific numbers, what worked, what failed, full context). The sub runs dedicated weekly promo threads for plain plugs. Pure "check out my new app" posts are removed by mods within hours.
• Karma / age gate: AutoModerator filters very-new accounts and accounts with negative or near-zero karma. If your account is days old, expect removal even on a good post.
• What works: Build-in-public posts with at least one specific number. Examples that did real numbers: a "vibe coded my first SaaS" thread and the brutal honesty of "I quit my job to build an AI SaaS, it flopped". Notice both lead with stakes, not a product link.

2. r/indiehackers

r/indiehackers is smaller than r/SaaS but has a tighter signal-to-noise ratio. The audience overlaps heavily with the indiehackers.com community, which means readers have already heard every generic "how I got my first 10 users" angle.

• Self-promo policy: Allowed when wrapped in real content. Bare link drops and "I built X, what do you think?" with no context get removed. The sidebar explicitly asks for posts that teach or share lessons.
• Karma / age gate: Less aggressive than r/SaaS but new accounts with no comment history get caught in the spam filter. Comment for a couple of weeks before you post.
• What works: Specific, opinionated lessons. "Why I killed my $400 MRR product" or "The one Stripe setting that cost me 6 weeks" outperforms "5 tips for indie founders".

If you're new and the karma gate is the problem, the founder's guide to karma minimums on Reddit covers the actual thresholds that matter.

3. r/SideProject

r/SideProject is the most permissive of the five. The sub exists for the purpose of sharing what you're building, which means the bar for "is this self-promo" is almost non-existent.

• Self-promo policy: Sharing your own project is the point of the sub. The rules forbid low-effort drops (one-line post + link), explicit lead-gen pitches, and anything with no actual project attached.
• Karma / age gate: Looser than the other subs in this list. Accounts that look brand-new still get caught by AutoModerator's standard new-account filter, but you don't need karma in the thousands.
• What works: A 30-second demo (GIF, Loom, or Vimeo) plus one specific question for feedback. "Here's what I built in 3 weekends, what would make you actually use it?" gets way more engagement than "Launching today!".

r/SideProject is the safest sub on this list for an early launch post. The trade-off is that the audience is fellow makers, not buyers. Treat it as feedback fuel and credibility, not revenue.

4. r/microsaas

r/microsaas is the smallest sub in this roundup and also the one with the most concentrated buying-intent audience for vibe-coded products. People here are explicitly looking for small, focused tools they can buy or copy.

• Self-promo policy: Allowed. The wiki and rules say share your micro-SaaS, but they're explicit that vague "I made a thing" posts get pulled. Posts need a concrete metric, a teardown, or a real lesson.
• Karma / age gate: Standard AutoModerator new-account filter. Not as aggressive as r/SaaS but very-new accounts still get caught.
• What works: Specific revenue, traffic, or conversion numbers paired with how you got them. "$47 MRR from 12 cold DMs to founders on X" works. "I built a SaaS, here's the link" gets removed.

For a worked example of a vibe-coded micro-SaaS post that converted, the r/SaaS teardown of 4 paying users in one day shows the same anatomy that lands here.

5. r/EntrepreneurRideAlong

r/EntrepreneurRideAlong is the journey-post sub. It's less crowded than r/Entrepreneur and the audience expects multi-week threads from real founders building real things.

• Self-promo policy: Permitted when framed as part of a building-in-public journey. Drive-by promo, affiliate links, and posts that read like ads are removed. Mods are active.

• Karma / age gate: New-account filter is on but moderate. The bigger filter is mod judgment; threads that look like a marketing exercise get pulled even if they pass AutoModerator.

• What works: A weekly or biweekly update thread. Start with a specific goal ("Going from $0 to $1k MRR with a vibe-coded scheduling tool") and post real numbers every update, including the bad weeks.

This is the sub where consistency beats virality. One great post and disappearing for 4 months underperforms five honest updates in a row.

Subs I left off, and why

• r/Entrepreneur: too broad, too many MLM and dropshipping refugees. The good content gets buried.
• r/startups: aggressive AutoModerator, mods bias hard against anything that mentions a product by name.
• r/webdev and r/programming: technical audience but explicitly anti-self-promo. Share code, not products.
• r/AI_Agents and similar trend subs: high noise, low retention, audience is mostly other builders rather than buyers.

A note on automation

Five subs is the maximum a solo founder can monitor by hand. Each one has 50 to 500 new posts per day, and the threads worth replying to are usually buried by hour two. If watching all of them in real time isn't your idea of fun, Bazzly does the watching and surfaces the threads worth a reply. Either way, the rule above each sub still applies: respect the self-promo policy, lead with substance, and don't post from a four-day-old account.

If you're doing this manually, the workflow is: set up a multireddit of these five, sort by new, check it twice a day, and reply to anything where your specific experience is useful. The launches come from comments, not from launch posts.
