Platform Market: No‑App Photo Sharing via QR Codes and Browser Cameras
A developer describes building Picshots, a no-download photo sharing platform that uses QR codes and browser camera APIs to let event guests upload photos directly from their phones into a real-time shared gallery. The article explains the technical stack (getUserMedia/WebRTC, presigned S3 uploads, Supabase Realtime, Next.js, Vercel), implementation details and edge-case fixes (iOS gesture requirements, orientation handling, sessionStorage to recover camera state), and usage metrics from production: 12,000+ events, a 92% guest participation rate, and an average of 8.3 photos per guest. The author also notes lessons learned and improvements (BarcodeDetector API, WebP support, admin dashboard).
Practical case study of a consumer-facing, web-first photo sharing product that demonstrates browser camera APIs and serverless architecture; relevant to event/experiential tech and web-first product design but not industry-shifting for core AdTech.
Key Takeaways & Evidence Grounding
- Picshots is a no-app photo sharing platform that uses QR codes and browser cameras to collect event photos.
- Picshots has been used at over 12,000 events and reports a 92% guest participation rate and an average of 8.3 photos per guest.
- The implementation relies on browser camera access via getUserMedia/WebRTC, presigned S3 URLs for direct uploads, and Supabase Realtime for live gallery updates.
- Uploads go directly from guests' browsers to S3 where a Lambda generates thumbnails and metadata is stored in Supabase.
