Unlike Supademo ($480/year), OneShot is pay-once: $20. Built for indie hackers who need demos occasionally - Product Hunt launches, landing pages, pitch decks. What you get: - Upload screenshots - Add annotations (arrows, text, hotspots) - Export HTML file - Own forever, use anywhere Same core functionality as subscription tools, but priced for reality: most founders make 2-3 demos per year, not 200. No monthly charges. Pay once, own your demo.
