Chat with the coding agents on your computer from a desktop app, your phone or any browser, and answer their prompts with a tap. A client for herdr and the Herdr desktop app's terminals.

_{Recorded on the demo, which runs in your browser.}

On your computer

• Mac: the desktop app for Apple silicon or Intel; drag it to Applications.
• Windows: the desktop app, Ovis-win-x64.exe; run it. If Windows shows Windows protected your PC, choose More info → Run anyway.
• Linux: the desktop app for Debian or Ubuntu, x64 or arm64 (sudo apt install ./Ovis-linux-*.deb); elsewhere the AppImage, x64 or arm64 (chmod +x Ovis-linux-*.AppImage).

The desktop app needs nothing else and runs its own terminals. To use your herdr sessions instead, on Linux or macOS:

curl -fsSL https://ovis.sh/install.sh | sh

On Windows, in PowerShell:

irm https://ovis.sh/install.ps1 | iex

Other ways, step by step: INSTALL.md.

On your phone

• iPhone: the TestFlight beta, from ovis.sh/beta.
• Android: the Google Play beta, from ovis.sh/beta.
• Browser: no app needed; add the page to the home screen.

To connect a phone, turn on the end-to-end encrypted Ovis relay in Settings → Phone & devices and scan its QR code. How it works →

• Agents as a chat. Claude Code, Codex, OpenCode and more. Supported agents →
• Prompts and approvals as cards. Answer with a tap.
• Push alerts. Even with the app closed.
• The live terminal, one click away. With a key bar on phones.
• Every workspace in one list. Other PCs over SSH too.

All features →

Limits: your computer has to be on and reachable (the Ovis relay, Tailscale, a VPN or an SSH tunnel). The Herdr desktop app's terminals work on Linux and macOS only.

Privacy: sessions stay on your computer, with no account. The optional relay can't read what is sent (trust model). Anonymous usage counts are on by default; Settings → About or OVIS_TELEMETRY=0 turns them off (what is sent).

• FAQ: herdr's own TUI, Tailscale, what leaves your machine, and how Ovis compares with collie, Happy, Paseo and others.
• INSTALL.md: every way to install, step by step, and what to do when a step fails.
• Demo: the real app on a made-up session, in your browser.

Built on herdr, with inspiration from chatmux, and powered by xterm.js, React, Bun and Lucide.
