You built something great. Now people need to find it. Here are 8 proven channels, a launch week playbook, and the exact strategies indie hackers use to get their first 1,000 users without spending a dollar.
Pick one or two free channels that fit your project instead of spreading yourself across all eight. Spend two weeks being a genuine member of two or three subreddits before you ever mention your project, line up your Product Hunt and Hacker News posts for the same launch week as your Reddit posts, and write down the story of why you built this so you can reuse it everywhere without starting from scratch. Most solo builders do not need a full marketing plan. They need one focused, honest week of outreach on the channels their exact audience already reads.
Choose 1 to 2 channels that match your audience, not every channel at once
Build genuine presence in target subreddits for two weeks before posting
Bundle Reddit, Product Hunt, and Hacker News posts into one launch week
Reuse your build story across platforms instead of writing new copy each time
95% of side projects fail not because they are bad products, but because nobody ever discovers them. Building is 20% of the work. Getting people to care is the other 80%.
There are millions of side projects online. Without active marketing, yours is invisible. Search engines, social algorithms, and word of mouth all require an initial push to get started, which is one reason Reddit deserves early attention: it appears in 77% of product review searches and ranks as the third most cited domain in AI Overviews, according to Ahrefs.
Your motivation peaks at launch. If you wait too long to market, you lose momentum. The best time to promote is when you are most excited about what you built.
You do not need a marketing budget. Reddit, Product Hunt, and Hacker News have sent more traffic to side projects than any paid ad campaign. You just need the right approach. Tools like MediaFast can help you draft posts that match each subreddit's tone before you hit submit, and the audience keeps growing too: Reddit's global daily active user base rose 17% year over year to 126.8 million for the quarter, according to CNBC's Q1 2026 earnings coverage.

Not all channels are equal. Here are the 8 best places to promote your side project, ranked by how effective they are for indie hackers and solopreneurs. Word of mouth still does the heaviest lifting: referral driven marketing converts 3 to 5 times higher than other methods, according to Demandsage, which is exactly the dynamic these channels are built to trigger.

Do not spray and pray. Coordinate your launch across all channels in one focused week for maximum impact, but read Hacker News's own posting guidelines and Product Hunt's official launch page before you commit to a day, since both platforms reward preparation over spontaneity. Keep your expectations realistic too: featured Product Hunt launches typically bring in 1,000 to 5,000 visitors and 10 to 150 signups on launch day, while non-featured listings usually see well under 500 visitors, according to shno.co's 2026 Product Hunt launch statistics.

Stop reading SaaS marketing advice and applying it to your side project. The playbooks are fundamentally different.
Reddit is the number one channel for side projects because it lets you reach thousands of people in your exact niche on day one, and it is also the single most cited source in AI chatbot answers. A Semrush study of over 150,000 citations found Reddit referenced 40.1% of the time, far ahead of Wikipedia at 26.3%, according to Visual Capitalist's analysis of the data. Here is how to do it right.

We pulled our own numbers instead of guessing. MediaFast analyzed 10,000 posts from our users between January and May 2026 and found Tuesday mornings, 7 to 9 AM ET, drove 1.8x the baseline engagement of an average post, with Wednesday morning and Sunday evening close behind.

Not sure which communities fit your project? Run your idea through MediaFast's free subreddit finder before you start commenting, so you spend your two weeks of karma-building in the right places.
Built specifically for sharing side projects. Most welcoming community for self-promotion.
For unique web tools and apps. Front page here means tens of thousands of visitors.
Share your journey and lessons learned. Direct links get removed, but story posts thrive.
Indie hacker community on Reddit. Great for milestone posts and feedback requests.
If your project is a web tool, share the technical story of building it.

Stuck on a first draft? MediaFast's free Reddit Post Generator can give you a starting point to rewrite in your own voice before you follow the five steps below.
Spend 2 weeks commenting helpfully in your target subreddits. Answer questions. Share opinions. You need post karma and a real comment history before anyone takes your posts seriously.
Write about why you built it, what problem you faced, and what you learned. People connect with stories. A post titled 'I built a tool to solve X after struggling with it for months' outperforms 'Check out my new app' every time.
Do not start with r/startups or r/entrepreneur. Post to the smaller, more targeted community first. If you built a design tool, post to r/design. If it is for writers, post to r/writing. Niche subreddits convert better.
Reply to everyone. Thank people for feedback. Answer questions in detail. The Reddit algorithm boosts posts with active comment sections, and genuine engagement builds trust.
Post the technical story to r/webdev, the business story to r/startups, and the product itself to r/SideProject. Same project, three different posts, three different audiences.
Reddit's long-standing community norm is the 90/10 rule: roughly 90% of your activity should be genuine participation, and no more than 10% should point back to your own project. It is not an automated, site-wide policy, but moderators enforce it by feel, and some subreddits hold posters to an even stricter 95/5 ratio.
MediaFast helps indie hackers and solopreneurs promote their projects on Reddit. AI-crafted posts that match each subreddit's culture, automated scheduling for peak engagement times, and built-in safety to protect your account.

Common questions about promoting your side project for free.
Zero dollars to start. The best side project marketing channels are completely free. Reddit, Product Hunt, Hacker News, Twitter/X, and dev communities all cost nothing but your time. Only consider paid ads after you have validated demand organically and have revenue coming in.
Before you finish building it. Start sharing your journey, collecting emails, and building an audience from day one. The biggest mistake indie hackers make is waiting until launch day to think about marketing. Build in public and you will have an audience ready when you ship.
Never drop a link and leave. Spend at least two weeks engaging genuinely in your target subreddits before mentioning your project. When you do share it, frame it as a story or a solution to a problem the community cares about. Use soft CTAs and always disclose that it is your project. MediaFast can help you craft posts that feel natural to each subreddit.
Yes, but manage your expectations. A Product Hunt launch gives you a spike of traffic, backlinks for SEO, and social proof you can use forever. It is not a growth strategy by itself. Treat it as one event in your broader launch week, not your entire marketing plan.
Reddit. It has more than 100 million daily active users organized into thousands of niche communities. Unlike Twitter where you need followers first, a single Reddit post can reach tens of thousands of people on day one. Posts also rank on Google for months, giving you long-term SEO value. The key is matching your project to the right subreddits and writing posts that provide genuine value.
