01 — Full-Stack Platform
Peer-to-peer video platform built end-to-end
Overview
Fumblr is a full-stack peer-to-peer video platform enabling spontaneous, real-time one-on-one video connections directly in the browser. No app installs, no account setup friction — you connect and it works.
The UI was designed to get completely out of the way once a session starts — minimal chrome, focus on the video feeds, controls accessible but unobtrusive.
Technical Challenges
User identity: Sessions need two real participants without requiring signup. Supabase handles ephemeral session tokens — users get a presence without a permanent account.
Video infrastructure: WebRTC in the browser requires signaling, ICE negotiation, and STUN/TURN handling. Daily.co's REST API manages the room lifecycle and peer connection, removing the most complex infrastructure layer.
Session state: Two users need to land in the same room simultaneously. The session matching logic handles room creation, link sharing, and joining — ensuring both sides connect to the same endpoint.
Design Decisions
The interface has one job: get you into a call and then stay out of the way. Full-bleed video feeds, controls only visible on hover, and a single end-call action. No sidebar, no chat panel, no feature creep.
The empty state (waiting for the other person to join) needed to feel intentional rather than broken. A minimal "Waiting for connection..." indicator with the session link visible keeps the user informed without visual noise.
