We Mass-Deployed 15-Year-Old Screen Sharing Technology and It's Actually Better

Helix, an AI platform where users watch autonomous coding agents work in cloud sandboxes, spent three months building a sophisticated 60fps H.264 video streaming pipeline to replace WebRTC, only to discover it failed on enterprise networks and poor WiFi connections due to buffering delays that left users watching 30-45 second old footage. The team implemented a simple fallback system using JPEG screenshots delivered via HTTP requests—15-year-old technology that provides reliable, stateless frames even on bad connections, automatically switching between high-quality video streaming and functional screenshots based on network conditions.
