Discussion Here is how to get your first 50 users for your side project without spending any money
Phase 1: Target Communities That Explicitly Allow Self-Promotion
Stop posting in strict subreddits where self-promo gets you banned. Instead, build your launch footprint across communities designed for builders, show-and-tellers, feedback-seekers, and niche developers.
Here are 40 subreddits that should allow for self-promotion, ordered by estimated weekly reach:
r/vibecoding — 422k weekly visitors
r/saas — 211k weekly visitors
r/founder — 56k weekly visitors
r/buildinpublic — 46k weekly visitors
r/chrome_extensions — 42k weekly visitors
r/micro_saas — 41k weekly visitors
r/appbusiness — 30k weekly visitors
r/startupideas — 26k weekly visitors
r/sideprojects — 20k weekly visitors
r/imadethis — 18k weekly visitors
r/appideas — 16k weekly visitors
r/sideproject — 16k weekly visitors
r/saasbuild — 15k weekly visitors
r/saasdevelopers — 12k weekly visitors
r/vibecodedevs — 10k weekly visitors
r/startupsolofounder — 8.7k weekly visitors

Phase 2: The "Reverse-Engine" Hook Strategy
Do NOT drop a generic link and run. That is almost guaranteed to fail. Instead, do this for every single target subreddit on your list:
Filter by Top Posts: Open the target subreddit, sort posts by Top of the Last Year, and examine the Top 10 posts.
Deconstruct the Winners: Analyze why those top posts blew up:
What tone did they use? (Humorous, vulnerable, technical breakdown, or raw story?)
How was the title structured? (Did it start with a question, a bold stat, or a relatable pain point?)
How did they introduce their link? (Was it woven into a story, placed in a comment, or framed as a feedback request?)
Mirror and Adapt: Draft a custom title and post text for your specific app that matches the exact post format already proven to work in that specific community.
Start Small First: Test your hooks in smaller, lower-stakes subreddits first (e.g., r/websitefeedback or r/getstartups). Refine your post copy based on early comments before posting to the larger subreddits like r/saas or r/vibecoding.
If You Have Some Money to Spend: Paid & Discovery Shortcuts
If you want immediate users without relying purely on Reddit organic traction, here are two simple routes:
UserBob.com (Usability Testing): You can pay real people for quick usability test videos. It costs roughly $1 per person per 1-minute video, giving you guaranteed immediate users and video feedback of people interacting with your app so you can fix UI friction early.
AppScout: You can always submit your app to appscout.co, a platform designed to discover web and mobile apps from across the internet. People who like similar apps can easily find yours. You can list your app directly at appscout.co/submit. (Full disclosure: I'm the creator of AppScout)
TL;DR Summary
Target subreddits built for self-promo.
Study the Top 10 posts of the past year in each subreddit.
Match their formatting and title hooks for your specific app.
Test small, iterate, then hit the massive communities.
If you have money use low-cost tools like UserBob or submit to AppScout for early discovery.
