Sink It for Reddit
"A cross-browser extension (Safari/Chrome/Firefox/Edge) that makes Reddit usable on the web, similar to RES but actively developed and supporting all Reddit designs, with around 300k users."
Marketing Channels
Apple App Store / Safari Extensions
Main user base is on Apple platforms; Safari extension distribution through the App Store is the primary channel
Chrome Web Store
Chrome version is only a few months old and has limited reviews compared to the Apple platform versions
Edge Add-ons / Firefox Add-ons
Available on Edge and Firefox; Edge approval process is notably slow

Reddit community (organic)
Built during the Reddit API controversy which created organic demand and visibility among Reddit power users
Growth Levers
- Improve premium feature discovery with a 7-day trial or explainer video showing what paid users get (directly suggested by a paying user)
- Better onboarding experience to communicate the value of premium — creator acknowledged this gap
- Prompt users for ratings/reviews on Chrome Web Store to build social proof (creator admits not doing this currently)
- Expand customization features like hiding unwanted UI elements and increasing link sizes for old.reddit.com
- Leverage the 300k user base for word-of-mouth growth within Reddit communities
First Customer Strategy
The extension was built during the Reddit API controversy in 2023, which created massive organic demand from frustrated Reddit users seeking alternatives to the degraded experience. The Apple platform (Safari extension) was the initial focus, capturing Reddit power users on macOS/iOS who had fewer alternatives.
Pricing Insight
99% of features are free. Revenue comes from premium features (dark mode on old Reddit) and donations. The creator acknowledges that premium features are not surfaced well enough, leaving conversion rate improvement on the table.
New Market Opportunities
- Android browser extensions (Firefox for Android) Chrome on Android doesn't support extensions, but Firefox for Android does — an opportunity to capture mobile Reddit users
- Reddit UX customization (element removal/resizing) Users want granular control: removing crosspost buttons, adding 'hide everything above', and increasing link sizes on old.reddit.com
Key Takeaways
- • Timing matters: building during the Reddit API controversy created massive organic demand that would have been impossible to replicate through paid marketing
- • Declining acquisition offers to prevent the product being turned into malware demonstrates the ethical tension in browser extension businesses — and builds user trust
- • A freemium model with 99% free features can still generate four-figure monthly revenue, but poor premium feature visibility leaves significant revenue on the table
- • Cross-platform browser extension development (Safari, Chrome, Firefox, Edge) multiplies reach but creates maintenance burden, especially with slow store approval processes (Edge)
- • Not prompting for reviews hurts discoverability on extension stores — a simple review prompt could dramatically improve social proof on Chrome Web Store
Sentiment Analysis

"I suspect you can increase your conversion rate to paid quite easily. I've been using the free version for sometime. And I have no idea if the paid version gives me the improvements that I care about. — josho"
"Dark mode is not working on old design. I will keep with RES for now. Looks hella buggy. — Giorgi"
"Why is there only one review for the Chrome extension? Is the Apple app store version the most used version? — fraXis"
