About Fault Line

Fault Line is a free community-powered platform for reporting potholes, broken streetlights, and infrastructure issues. We built it because reporting a pothole shouldn't be harder than the pothole itself.

The system for reporting infrastructure problems — calling 311, waiting on hold, getting no confirmation, no tracking, no follow-up — was designed in 1996. It hasn't changed. Authorities count on citizens giving up after one failed attempt. Fault Line changes the equation: individual complaints are easy to ignore; community-verified, GPS-documented, legally-significant reports with fiscal impact projections and public accountability scores are not.

How it works

1. Spot an issue — pothole, broken light, crumbling sidewalk, fallen tree, and 20 more categories
2. Submit a report in 10 seconds with GPS location, photo, and severity (AI helps auto-fill)
3. Your community verifies — when 3 people report the same problem, it's confirmed
4. At 10 community reports, authorities are notified automatically with a professional evidence packet
5. A public countdown tracks their response — and legal demand letters create consequences for inaction

What makes us different

Where we operate

Fault Line currently covers Massachusetts, Rhode Island, and New Hampshire with 42 pre-configured government authorities. The app works anywhere — GPS and photo reporting are universal — but authority identification and auto-escalation are available in these three states. We expand based on community demand.

Our technology

Built with React Native (Expo) for mobile, Next.js for web, Supabase for the backend, and Claude AI for photo analysis. Reports are GPS-verified, community-validated, and legally timestamped. The app works offline, supports 5 languages, and is fully accessible with screen reader support, voice commands, and audio-guided reporting.
