Read license plates, search any vehicle in seconds, investigate incidents, and own your data. Self-hostable. Free and open source.
We believe this technology has legitimate potential to help fight crime, but for now, it's doing more harm than good because of the way it is being done.
Without strong guardrails, transparent oversight, and privacy by design, these systems can enable mass surveillance, unauthorized tracking, misuse, security threats, inaccurate results, and a lack of accountability. That doesn't just put citizens at risk — it puts the organizations relying on these systems at risk too.
To combat this, we're building a different approach: open source, privacy-first, secure by design, transparent, and accountable from day one — built for private organizations with dedicated support.
Mount cameras at entrances and key areas. No proprietary hardware lock-in.
Vehicles are detected and logged automatically, in real time.
Search any vehicle in plain language, or set watchlists for instant alerts.
Build timelines, export evidence, review analytics — all in one place.
Detect and classify every vehicle in real time.
Find the right vehicle in seconds, not hours.
Ex: Show me all white Toyota SUVs seen after 8 PM.
Built for responsible deployment.
Turn activity into intelligence.
Same capability class. A completely different relationship with your data.
The core platform is free and open source. Safety shouldn't have a price tag only well-funded organizations can afford. We've also seen organizations pull back from LPR tools because of the harm they can cause when built without transparency. Our primary users — LP teams — are often stretched thin without access to the tools they need, so we built Whistle to be open, transparent, and accessible to everyone.
No — Whistle works with your existing cameras. For best accuracy, you can pair it with dedicated LPR-grade cameras, available from several hardware vendors as a one-time investment. We're also developing our own hardware, launching soon.
Whistle achieves up to 95% license plate recognition accuracy under our benchmark conditions. That's meaningfully ahead of the 70% range we found in comparable tools during our research.
Wherever you decide. Self-host on your own infrastructure or use a dedicated deployment. We don't access, store, or sell your data — you own 100% of it.
Private organizations that need vehicle recognition with real guardrails: property managers, campuses, logistics sites, retail groups and similar operators — with dedicated support.
Privacy by design: role-based access control, complete audit logs, retention controls, and transparent oversight of every search and export.
