Why local-first
The same four ideas run through every product we ship.
Privacy by architecture
Your files are never uploaded. There is no server to leak, subpoena or breach — the work happens on your device.
Instant & offline
No round-trips, no queues. WebAssembly runs at native-ish speed and keeps working when your connection doesn't.
No accounts, no lock-in
Nothing to sign up for. Open a tab, do the work, close it. Your data stays in formats you already own.
Open where it counts
Several tools are fully open source; the rest run entirely client-side, so anyone can watch the network stay silent.
