Indie Dev Ships RSStoKindle, Built with OpenClaw Vibecoding, on Product Hunt
RSStoKindle, built by indie developer @martyamark, launched on Product Hunt on September 6. The service turns Substack posts, blogs, and articles into a daily digest delivered to the user's Kindle on a schedule — like a "modern daily newspaper." The developer says the tool helped him break the habit of scrolling his phone first thing in the morning.
Confirmed
- The project started in March this year; the first version was built via OpenClaw vibecoding while the developer was working out at the gym, originally tied to a need related to Cal Ne… (the post is truncated; see the original for details)
- After 6 months of development and operation, the product now has 57 weekly active users and receives thank-you emails from strangers every week, showing strong retention
- Growth came mostly from cold-starting on Reddit communities: posts in niche hardware communities like r/kindle and r/jailbreakkindle drove most user acquisition
- It launched on Product Hunt on September 6, accompanied by a growth retrospective series
Why it matters
- This is a textbook indie-hacker example of "vibecoding + community cold start": use AI-assisted tools to ship a first version fast, then rely on niche community distribution rather than paid ads
- 57 weekly actives is small in absolute terms, but weekly thank-you emails from strangers show rare, high-quality user stickiness — a useful reference for cold-starting niche utility products
