Sending is a self-hosted, encrypted voice and text platform. Run your own server. Own your data. Talk freely.
Voice data is encrypted with AES-256-GCM before it leaves your device. Not even the server can listen in.
The first time you connect, your client remembers the server's identity. If anything changes — like a man-in-the-middle attack — you'll be warned before any data is sent.
UDP voice relay with Opus compression delivers real-time audio with minimal delay, even on modest hardware.
Choose how you talk. Use Push-to-Talk with a custom key or mouse button that works even when the app is in the background, or switch to Voice Activity mode and just start speaking.
Send messages in dedicated text channels alongside voice. All messages are encrypted before they're stored — even if someone accessed the server's database, your conversations stay private.
Native desktop apps for Windows, Linux, and macOS — plus a web client that runs entirely in your browser.
Save multiple servers to your list and switch between them instantly. Connect to your gaming group, your team at work, and your friends — all from one app.
Connect with just a display name. Profiles are stored locally on your device — the server never holds credentials.
Run the server on your own hardware. No third-party accounts, no data collection, no subscriptions.
Fully open source. Inspect the code, contribute, or fork it. Transparency is not optional — it's the default.
Get the native desktop app for the best experience, or use the web client instantly.
