Hey Product Hunt! I’m Hongyang, an indie developer and solo founder. I built DevSnapKit because I was genuinely exhausted from opening Figma every single time I needed a decent launch graphic, Twitter mockup, or OpenGraph card for my projects. Most existing mockup tools have two big pain points: 1. They slap giant ugly watermarks on the free tier to force you into a $9–$18/mo recurring subscription. 2. They upload your images to third-party cloud servers to render—which is a privacy risk if you're sharing internal dashboards, API staging outputs, or Stripe revenue metrics. So I built DevSnapKit (https://devsnapkit.com) to do things differently: • 100% In-Browser Privacy: Built on HTML5 Canvas. Zero images or screenshots are ever uploaded to any server. Completely safe for private metrics. • Clean Free Tier: Crisp 2x HD exports with zero forced watermarks. • Dynamic Scannable QR Codes: Embed real, scannable QR codes into your 4K cards so viewers can scan straight to your product. • One-Click Batch Multi-Size Export: Download 16:9, Twitter/OG, 4:3, and 1:1 in one click without distortion. • Anti-Subscription Pricing: Free core tool, with a one-time lifetime pass for Pro features. I’d love to hear your feedback, thoughts, and feature requests. What should I build next?
