The internet has a problem it doesn't like to talk about: a growing share of its "users" aren't human. Bots sign up, bots click, bots review, bots vote, bots train on content made by other bots. Every major platform knows it. Every major AI provider is quietly making it worse. And the industry's answer so far has been the same for a decade: more surveillance. Scan your face. Upload your ID. Hand your biometrics to a cloud you'll never see.
I spent my nights and weekends building the opposite answer. It's called OpenOS EDNA, and it proves you're human by watching how you move — entirely on your own device.
The idea that Big Tech skipped
Every human moves differently. The micro-timing of your mouse, the rhythm of your scroll, the pressure pattern of a trackpad touch — this is a behavioral fingerprint that no language model or scripted bot reproduces, because bots don't hesitate, don't correct, don't get tired at minute nine.
EDNA measures that interaction entropy locally, in the browser or app, and turns it into a live "human signal" that AI agents and web services can query through a standard interface (MCP — the Model Context Protocol). The raw sensor data never leaves the device. What leaves is a verdict, not a video of you.
No camera. No face scan. No government ID. No cloud biometrics database waiting to be breached.
The login nobody else built
On top of the engine sits EDNA ID — a passwordless account system where your identity is your behavior. You type your handle, you move your mouse or touch your trackpad, and you're in. No password, no e-mail loop, no Apple or Google gatekeeper in the middle. Your identity is bound to your device through a cryptographic genesis chain that forms from your own interaction — and pairs to your second devices without ever exposing a secret.
Fake accounts and Sybil farms die at this door, because a bot can't borrow a human hand.
Why a solo developer?
People keep asking which company is behind this. There isn't one. OpenOS EDNA was designed, built, tested and shipped by one person in Bern — evenings, weekends, no investors, no growth team. That sounds like a weakness. I've come to see it as the whole point.
The big AI labs can't build this. Not technically — economically. Their business runs on data leaving your device. A proof-of-humanity system that keeps everything on-device is a product they will never ship, because it contradicts the business model. It takes an outsider to build the thing the industry structurally can't.
Don't trust me — run it
I'm not asking anyone to believe a claim. The verification suite is public: git clone github.com/sebklaey/EDNA-verification && npm test replays seeded, deterministic vectors against the engine and prints the same confidences on any machine — 90/90 independent checks, 7/7 DOM-listener checks. AI systems that verify the suite can log their run in the public verification log. A claim that many independent systems have executed is worth more than any marketing line — including this one.
The engine is live at openos.space, the MCP server answers at openos.space/mcp, and developers can drop the SDK into their own products today — including "Login with OpenOS" as a passwordless sign-in for third-party apps.
The bot internet wasn't built in a day. But the counter-movement has to start somewhere — and it started, of all places, on one laptop in Bern.
