Where to share side projects: r/SideProject alternatives and places to get feedback, in their own words

Share a side project where showing it is the point. On Reddit that's r/SideProject, built for sharing projects and getting feedback on them, plus a few alternatives with their own rules: r/sideprojects (a different subreddit) allows advertising a project, r/Startup_Ideas and r/indiebiz welcome a description of what you made, and r/roastmystartup and r/websitefeedback take it as a request for honest feedback. Outside Reddit, SideProjectors lists projects for free, Show HN takes anything people can try now, and weekly launch boards keep a project up for a week.

This guide is about showing a project and asking what people think. Launching it and recruiting testers have their own guides, linked below. Each place's rule is quoted from its own pages, and its page on our list has the source and the date we read it. We don't post projects or measure what a post brings, and we take no money from the places we list.

01The short list

Every place in this guide, with the kind, the cost where the place states one, and the date of our last check. Subreddits show "couldn't check" because Reddit blocks our checker, and they state no cost; their rules are below.

02r/SideProject and r/sideprojects are not the same

Two subreddits, one letter apart, with different rules.

• r/SideProject, singular, is the big one. Its description is the whole pitch: "r/SideProject is a subreddit for sharing and receiving constructive feedback on side projects." We couldn't read its sidebar rules, so read them before you post. The word that matters is feedback: a post that asks for it fits better than an announcement.
• r/sideprojects, plural, allows advertising a project, with a limit on repeats: "In order to share your project again, significant changes must have happened since the last post." Its rules post also asks for a flair and rules out blatant spam.

If you post in both, write two posts. The first wants a conversation; the second allows a pitch but not the same one twice.

03Other subreddits for showing what you made

• r/Startup_Ideas is for ideas, and its description says "Links and discussion about startups and descriptions of startups are welcome!" It suits a project that's still more idea than product.
• r/indiebiz, from its description: "A Reddit for small businesses, independents and startups to offer and share services, products, resources, and insight." We couldn't read its sidebar rules.
• r/buildinpublic is for sharing progress as you build: its description invites makers "to openly share their journey as they build projects in public." The feed had no rule about promotion, so check the sidebar.
• r/IMadeThis: the feed gave us neither a description nor a rule. The name invites a show-and-tell post, but we can't tell you what its moderators allow. Read its sidebar first.

If you're after testers rather than opinions, r/alphaandbetausers and r/betatests exist for that; they're in where to find beta users.

04Where to get feedback: roasts, websites, design

These subreddits take your project as a request. Ask a question, and give people what they need to answer it.

• r/roastmystartup takes your startup or idea to be roasted. Its moderators warn about one habit in particular: "We are receiving a ton of spam from people posting one-line posts with links to product hunt. If you do this it will be removed and you will be banned."
• r/websitefeedback is the one for landing page feedback. Its updated rules say "Posts must now include a working link to your website", and they ask for context: what the site does, who it's for and what feedback you want. Posts need a flair, and promotional posts are removed.
• r/Design_Critiques: the feed had no description or rule we could read. For feedback on a design rather than a business, it's the natural place, but read the sidebar before you post.

05The subreddit for what you built

A side project built for one community often belongs in that community's subreddit rather than a general one. Most of those keep projects to a pinned showcase thread:

• r/javascript: the weekly Showoff Saturday thread.
• r/Python: a monthly Showcase Thread.
• r/selfhosted: a weekly megathread for new projects.
• r/Notion: a fortnightly self-promo and showcase thread.

The people reading those threads already use what you built on, which a general side-project feed can't promise. The full calendar of these threads, and what gets a post removed, is in how to promote a startup on Reddit. For a Mac or iPhone app, r/macapps and r/iosapps have their own monthly threads and formats: see where to promote a Mac or iOS app.

06SideProjectors: a free listing, and a marketplace

SideProjectors describes itself as "a friendly marketplace to sell and buy interesting side projects from other people." You can list a project to show it or to sell it, and it costs nothing either way:

D036Side Projectors·Cost

“SideProjectors is free. There is no cost to submitting a project and we do not take any commission when a project is successfully sold.”

Our reading: Free; no commission on sales

You need an account to submit, and a person looks at each project first: "Most projects get reviewed within 2-5 business days, but it can vary depending on volume." That's slower than a Reddit post, and the listing sits on a site made for browsing side projects rather than in a feed. It's also the one place in this guide built for selling a project, if you've stopped working on it. Other sites that list a project for free, launch boards and directories alike, are in free startup directories, with what free costs at each.

07Show HN, once people can try it

Show HN takes only what people can try now, not landing pages. Its full rules are in where to launch a developer tool. If your side project runs in a browser or installs in a minute, it fits; a waiting list doesn't.

08Weekly launch boards

A launch board puts a project in front of people who browse new products, for a set time. Two on the list run weekly: Peerlist Launchpad and Smol Launch. Their cost is in the table above, and how Peerlist's week works is in Product Hunt alternatives, with the other weekly boards. Getworm is different: you offer early users a deal for joining, and its free tier is in where to find beta users.

These are launches, not feedback threads. Use one when the project is ready to be used, not while you're still deciding what it is.

09How to ask for feedback people can answer

The rules above agree on a few things. None of it is our own experience of posting; it's what the moderators and sites say.

• Give context, not just a link. r/websitefeedback wants what the site does, who it's for and what you want to know. r/roastmystartup bans one-line posts.
• Make the link work. r/websitefeedback requires a working link, and Show HN wants something people can try without barriers.
• Ask a specific question. r/websitefeedback asks you to say what feedback you want. Name it: whether the pricing is clear, say, or whether the first screen explains the product.
• Share again only after real changes. r/sideprojects puts it in its rules, and posting the same thing twice is what Reddit's own spam policy calls repetitive content (see how to promote a startup on Reddit).
• Use the flair. r/sideprojects and r/websitefeedback both require one.
• Don't turn feedback into a vote drive. Asking for Product Hunt upvotes is what gets r/roastmystartup posters banned.

A post that fits most of these rules

Put together, the rules describe one kind of post. It works in r/SideProject, in the feedback subreddits and, trimmed, in a showcase thread:

1. One line on what it is, in plain words, not a slogan.
2. Who it's for and the problem it solves for them.
3. A working link, and whether people need to sign up to try it.
4. That you made it, and whether it's free, paid or both.
5. What you want to know: one or two specific questions.
6. The right flair, where the subreddit asks for one.

Then stay for the replies. A post you answer under is the opposite of the drive-by link the moderators above remove.

Pick by stage

• An idea: r/Startup_Ideas, or r/buildinpublic to share progress as you go.
• Something people can use: r/SideProject, r/sideprojects, and Show HN if people can try it at once.
• A website or landing page: r/websitefeedback.
• A design: r/Design_Critiques, after reading its sidebar.
• A project you'd sell, or that you want listed somewhere it stays: SideProjectors.

10How we checked

Subreddit rules come from each subreddit's public RSS feed, which we read on 30 September 2026 because Reddit blocks our link checker. The feed carries the description and the pinned posts, not the sidebar, so a subreddit can have rules we haven't seen; for r/IMadeThis and r/Design_Critiques it carried nothing we could quote. SideProjectors' price and review time come from its own help pages, read on 29 September 2026. Every quote links to the place's page on the list, with the source and the date. Read the sidebar before you post. Nobody pays to be listed or to appear in a guide. Read how we check for the details.

11Questions

01

Where can I share my side project?

On Reddit, r/SideProject is built for sharing side projects and getting feedback, and r/sideprojects allows advertising one. r/Startup_Ideas and r/indiebiz welcome descriptions of what you made. Outside Reddit, SideProjectors lists projects for free, Show HN takes anything people can try now, and weekly launch boards such as Peerlist Launchpad keep a project up for a week.

02

Is r/SideProject the same as r/sideprojects?

No. r/SideProject, singular, describes itself as a place for sharing and receiving constructive feedback on side projects. r/sideprojects, plural, is a separate subreddit that allows advertising projects, requires a flair, and lets you share a project again only after significant changes.

03

Where can I get feedback on my startup or landing page?

r/roastmystartup takes startups and ideas to be roasted, and bans one-line posts that link to Product Hunt. r/websitefeedback is for websites and landing pages: include a working link and say what the site does, who it is for and what feedback you want. Read each sidebar before you post.

04

Is SideProjectors free?

Yes, by its own help page: submitting a project costs nothing, and it takes no commission when a project sells. You need an account, and most projects are reviewed within a few business days.

05

Can I post my side project on Show HN?

Only if people can try it now. Show HN's own page rules out landing pages, sign-up pages and work that isn't ready for users. The full rules are in where to launch a developer tool.
