How to share your startup on r/webdev
TL;DR
r/webdev is a free Reddit community for front-end and back-end web developers with about 3.3 million members (October 2026). Project and feedback posts are allowed on Saturdays only, under the Showoff Saturday flair, and commercial promotion is banned on every day of the week. It suits founders who built something technical and want blunt feedback from developers.
How we checked: we read these rules through public subreddit trackers in October 2026. Read the sidebar and the pinned posts before you post, since moderators update the rules.
What is r/webdev?
r/webdev is a subreddit, a topic forum on Reddit, that describes itself as a community for all things web development, both front-end and back-end. Members post questions, articles and resources about HTML, CSS, JavaScript frameworks, hosting and APIs. Readers are working developers, students and freelancers, and they judge a project on code, speed and design first.
The domain authority of 95 on this listing belongs to reddit.com. Links in Reddit posts carry the nofollow attribute, so a post here passes almost no SEO weight to your site. The real benefit is technical feedback, a burst of developer traffic and early users for developer tools.
Who should post on r/webdev?
- Founders of developer tools, open-source libraries, APIs or website builders whose buyers are web developers.
- Technical founders who want a code-level review of a web app, landing page or portfolio.
Skip it if:
- Your product targets consumers or non-technical buyers. Developers on this subreddit will not become your customers.
- You want to post an ad, a discount code or a hiring call. The rules ban commercial promotion and solicitation, and violations can end in a ban.
How much does r/webdev cost?
Posting on r/webdev is free, and a Reddit account is all you need. For paid reach, Reddit sells self-serve ads through Reddit Ads (ads.reddit.com) with targeting by community and interest, the only way to put a commercial offer in front of this audience.
How do you share your startup on r/webdev?
- Open r/webdev and read the rules in the sidebar. Three of them shape any startup post: No self-promotion (follow reddiquette and Reddit's 9:1 guideline, nine regular contributions for every promotional one), No commercial promotions/solicitations ("Violations can result in a ban") and No soliciting feedback not on Saturday.
- Take part first. Answer questions and comment for a few weeks, so your account shows genuine participation.
- Wait for Saturday. Sharing a project, a portfolio or anything you want feedback on is limited to Showoff Saturday, and the moderators remove such posts on any other day.
- Create the post, pick the Showoff Saturday flair and write about the build: what it does, the stack, what was hard and the exact feedback you want. The ban on commercial promotion still applies on Saturday, so leave out pricing, coupons and sales calls.
- Stay online for the first hours and reply to every comment.
Tips to get more out of r/webdev
- Lead with the technical story. A title like "Built a form builder on SvelteKit and Postgres, roast my architecture" fits the room. "Check out my startup" gets ignored or removed.
- Ask one precise question, such as mobile load time or how readable your API docs are.
- Show, then link. Add a screenshot or short GIF and a live demo that works without a sign-up wall.
- Credit your reviewers. Fix what commenters found and thank them by name in your changelog.
Our verdict
With about 3.3 million members, r/webdev puts a strong Showoff Saturday post in front of people who build for the web every day. The rules are strict: one day a week and no sales pitch. Use it for developer products, and choose another subreddit for a consumer launch.
