How to share your startup on r/Python
TL;DR
r/Python is a free Reddit community for news, packages and discussion about the Python programming language, with about 1.5 million members (October 2026). Projects appear as Showcase posts that explain what the project does, who it is for and how it compares with existing tools. It fits founders whose product is a Python library, tool or open-source project, and it does nothing for a consumer app.
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/Python?
r/Python is a subreddit, a topic forum on Reddit, that calls itself the largest Python community on Reddit. It covers Python news, packages and meta discussion, and it sends beginner questions to r/learnpython. The moderators run daily threads, such as the Sunday Daily Thread: What's everyone working on this week?, next to regular flairs for Discussion, News, Resource and Tutorial posts.
The domain authority of 95 on this listing belongs to reddit.com. Links in Reddit posts carry the nofollow attribute, so the gain from a post here is developer attention, GitHub stars, bug reports and early adopters, with little direct SEO effect.
Who should post on r/Python?
- Founders of Python libraries, command-line tools, frameworks, data tools or APIs with a Python SDK.
- Open-source maintainers with a hosted or paid version, as long as the post centres on the code.
- Technical founders who can explain design choices and trade-offs in plain words.
Skip it if:
- Your product has no Python angle. Off-topic posts get removed.
- You only have a landing page and a waitlist. This audience wants code, docs and a repository to read.
How much does r/Python cost?
Posting on r/Python is free and needs only a Reddit account. For paid reach, Reddit sells self-serve ads through Reddit Ads (ads.reddit.com), with targeting by community and interest.
How do you share your startup on r/Python?
- Open r/Python and read the rules and pinned posts in the sidebar before you write anything.
- Build some history first. Comment in the daily threads and in discussions for a few weeks, so your account reads as a community member.
- Write a Showcase post with three sections: What My Project Does, Target Audience (who should use it, and whether it is ready for production) and Comparison (how it differs from the tools people already use). Low-effort posts and bare promotional links get removed.
- Link to the source code or documentation, add the install command (pip install plus the package name) and a short code sample.
- For work in progress or a small update, reply in the Sunday Daily Thread: What's everyone working on this week? and save the standalone post for a real release.
Tips to get more out of r/Python
- Open with code. A five-line usage example near the top of the post earns more trust than any adjective.
- Be honest in Target Audience. Calling a weekend project production-ready invites a pile-on in the comments.
- Compare by name. If you built a faster CSV parser, name pandas or Polars and share a benchmark that readers can rerun.
- Put the licence and repository up front. Companies check the licence before they adopt a package.
- Answer every technical question in the first hours, including the harsh ones.
Our verdict
r/Python rewards real engineering and has no patience for ads. A clear Showcase post for a useful Python tool brings stars, contributors and first users from a very large developer audience. For a product outside Python, a broader founder subreddit is the better match.
