Why Reddit Works
Browser extensions have the lowest friction of any product type on Reddit. Users can go from reading your post to using your extension in under 10 seconds. Reddit's tech-savvy audience installs extensions frequently and is always looking for tools to customize their browsing experience. Extensions that enhance popular websites like YouTube, GitHub, or Twitter find their exact audience in those sites' dedicated subreddits.
Browser extensions win on Reddit by being surprisingly useful for a problem nobody realized they had until you showed them.

Pro tip: If your extension modifies a popular website, post in that website's subreddit rather than a general tech sub. An extension that improves YouTube belongs in r/youtube where users will immediately understand the value.
Posting Strategy
🎯
Match extension to subreddit
Find the subreddit for the website or workflow your extension enhances. A Gmail extension goes to email productivity subs. A GitHub extension goes to programming subs. Context matters.
📝
Demo the before-and-after
Show two screenshots: the website without your extension, and the same page with your extension active. Make the improvement immediately obvious without any explanation needed.
⏰
Address privacy upfront
State exactly what permissions your extension requests and why. Link to your source code if possible. Reddit users are privacy-conscious and will check your extension's permissions before installing.
The best extension launches get shared not because of the feature list, but because someone said 'I've wanted this for years.'

I built a browser extension that shows you the actual price-per-unit on Amazon so you can stop doing mental math
Every time I compared products on Amazon I was pulling out my calculator to figure out which size was actually cheaper per ounce. So I built an extension that does it automatically — it adds a clear price-per-unit label to every Amazon listing. Works on all Amazon domains, handles different unit types, and highlights the best deals in green. No data collection, no account needed, open source. Works in Chrome, Firefox, and Edge.
