The Best Subreddits to Promote Your SaaS (Grouped by What They Allow)

How to use this list

Subreddits fall into three groups, and you should treat them differently:

1. Launch-friendly: self-promotion is the point. Great for first feedback and early users, but most readers are other makers.
2. Founder and business communities: active discussions, usually strict about promotion. Many allow it only in weekly or monthly threads.
3. Buyer communities: where your actual customers hang out. Promotion is usually banned, but helpful answers that mention a tool when asked are often fine.

Rules change, moderators change, and some communities go private. Before posting anywhere, read the sidebar, the rules page and the pinned posts. Our Reddit marketing guide explains the sitewide rules and post formats that hold up.

Launch-friendly subreddits

These explicitly welcome people sharing what they built, usually with a request for feedback:

• r/SideProject: the go-to place to share a project; include what it does, who it is for and what feedback you want.
• r/alphaandbetausers: for recruiting early testers.
• r/IMadeThis: broad maker showcase.
• r/roastmystartup: brutal feedback on your landing page or idea.
• r/shamelessplug: low-value for traffic, but explicitly allows it.
• r/buildinpublic: progress updates and lessons from building.
• r/microsaas: small SaaS products, often solo founders.
• r/indiehackers: indie founders sharing products and lessons.
• r/ProductHunters: for sharing Product Hunt launches.
• r/startup_ideas: for validating ideas rather than launching.

Best practice: lead with the problem, add a screenshot or GIF, ask a specific question ("Would you pay for X or is Y enough?"), and reply to every comment.

Founder and business communities

High-quality discussions, strict on promotion. Contribute first, and use designated threads:

• r/SaaS: SaaS founders and operators. Value-first posts about growth, pricing and churn do well; check current rules for product posts.
• r/startups: strict no-promotion rules outside designated threads such as their recurring "share your startup" posts.
• r/Entrepreneur: large and broad; promotion is restricted.
• r/EntrepreneurRideAlong: journey posts and lessons, somewhat more tolerant of context links.
• r/smallbusiness: owners of small businesses; strictly no promotion, but great for understanding buyer problems.
• r/growmybusiness: growth questions from small business owners.
• r/marketing and r/digital_marketing: marketers; strict on self-promotion.
• r/SEO and r/bigseo: SEO practitioners; very strict on promotion and low-quality posts.
• r/juststart: building content sites; detailed case studies are welcome.
• r/sales: sales professionals; tool spam is unwelcome but tool discussions happen.

AI and LLM communities

AI audiences are large but saturated with launch posts, so quality matters:

• r/ChatGPT: huge and general; self-promotion is restricted and usually confined to specific threads or flairs.
• r/OpenAI: OpenAI product discussion; tool showcases are limited.
• r/ChatGPTPro: power users; detailed workflows do well.
• r/artificial: broad AI news and discussion.
• r/AI_Agents: agent builders; technical posts about how you built something get engagement.
• r/LocalLLaMA: local models; very technical and skeptical of hype, strict on promotion.
• r/PromptEngineering: prompt techniques; share genuinely useful prompts.
• r/singularity: futurism and AI news; not a good fit for product posts.

The format that works: "Here is how I built X with [model/framework], what broke, and what I would do differently." See our AI startups page for how we approach AI products specifically.

Developer and open-source communities

Developers respond to code, benchmarks and honesty:

• r/webdev: has a recurring Showoff Saturday for sharing projects; other days are strict.
• r/programming: links to technical articles; product announcements are unwelcome.
• r/opensource: open-source projects and licensing discussions.
• r/selfhosted: self-hosted alternatives to SaaS; welcomes new projects that are genuinely self-hostable.
• r/coolgithubprojects: share GitHub repos directly.
• r/devops, r/sysadmin: practitioners; help-first only.
• r/reactjs, r/nextjs, r/node, r/Python, r/golang, r/rust: framework communities; many have showcase threads or flairs.
• r/javascript, r/typescript: language communities with self-promotion limits.

Lead with the repo and the technical decision, not the pricing page. Pair this with a good repo: see GitHub SEO.

No-code, productivity and tool communities

• r/nocode: no-code builders; tool comparisons and builds are welcome.
• r/Bubbleio, r/webflow, r/Supabase, r/zapier: platform communities; great if you integrate with them.
• r/productivity: large and strict; workflows beat product posts.
• r/Notion, r/ObsidianMD: power users who love templates and plugins.
• r/chrome_extensions: for sharing browser extensions; see our Chrome extension guide.
• r/iosapps, r/androidapps: app discovery; follow their posting formats.
• r/AppHookup: app deals and discounts, useful for limited-time promotions.
• r/InternetIsBeautiful: useful, free web tools; strict rules on what qualifies.

Niche buyer communities

These have your actual customers. Promotion is usually banned; helpful expertise is welcome. Find the equivalent for your market:

• r/freelance, r/freelanceWriters: freelancers (invoicing, contracts, client tools).
• r/ecommerce, r/shopify, r/FulfillmentByAmazon: online sellers.
• r/realtors, r/RealEstate: real estate professionals.
• r/agency: agency owners.
• r/Accounting, r/Bookkeeping: finance professionals.
• r/Teachers: educators (classroom and education tools).
• r/humanresources, r/recruiting: HR and hiring tools.
• r/msp, r/ITManagers: IT services and management.
• r/content_marketing, r/emailmarketing, r/PPC: marketing tools.

To find more, search Reddit for your buyers' job titles and problems, and note which subreddits appear repeatedly in Google results for "[problem] reddit".

A posting plan for the first month

• Week 1: join 8-12 subreddits across the three groups. Read rules, comment helpfully in buyer communities daily, no links.
• Week 2: post in 2-3 launch-friendly subreddits with a specific feedback request.
• Week 3: post a lessons-learned or data post in one founder community, following its rules.
• Week 4: answer recommendation threads in buyer communities, mentioning your product with disclosure only where it truly fits.

Track signups from each subreddit with UTM-tagged links. After a month, focus on the two or three communities that send users who activate. If you want a hand running this consistently, see our Reddit marketing service.

A launch post template for r/SideProject

Adapt this structure rather than copying it word for word:

Title: "I built [product] to [solve specific problem] after [personal trigger]. Looking for feedback on [specific thing]."

Body:

• The problem (2-3 sentences): what was painful and for whom.
• What I built (2-3 sentences): what it does, in plain words, plus one screenshot or GIF.
• What is working and what is not: one honest sentence each.
• The question: one specific question, such as "Is the pricing page clear?" or "Would you trust this with your Stripe data?"
• Link: one link, at the end.

Reply to every comment for the first 24 hours. Posts where the maker engages tend to stay visible longer and turn commenters into users.
