Ovis shows the coding agents on your computer as chats you answer with a click or a tap, in any browser, the Mac app or your phone. A client for herdr, formerly herdr web UI.
Recorded on the demo, which runs in your browser.
On your computer
- Mac: download Ovis.dmg, open it and click Install.
- Windows: download Ovis.exe, run it and click Install.
- Linux: run this in a terminal.
curl -fsSL https://ovis.sh/install.sh | sh
Each one adds herdr and Bun if they are missing; Node is not needed. Other ways to install, 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.
With Tailscale on in both, scan the QR code your computer shows to connect. No Tailscale? Turn on the end-to-end encrypted Ovis relay under Settings → Phone & devices and scan its QR code with the phone's camera: it opens Ovis in the phone's browser. How it works →
- Any agent herdr runs. Claude Code, Codex, OpenCode, pi, omp, Gajae Code, Hermes, Grok and more, most as a chat. Supported agents →
- Prompts as cards. Checked as still current before your answer is sent.
- The live terminal, one click away. The same pane herdr shows, with a key bar on phones.
- Every workspace in one list. Tabs, splits and other PCs over SSH, with the ones waiting on you marked.
- Push alerts. When an agent asks something or finishes, even with the app closed.
- Free and MIT. Runs on your own computer, with no account to sign up for.
Limits: Ovis needs herdr and your own computer, switched on, and your phone has to reach it (Tailscale, a VPN, an SSH tunnel or the Ovis relay).
Privacy: sessions stay on the computer that runs each agent, and Ovis has no account. Its optional relay, off until you turn it on, sees which phone connects to which PC, from which address, when and how much, but can't read what is sent (trust model). Anonymous usage counts are on by default; Settings → About → Anonymous usage counts shows what is sent and turns them off, as does OVIS_TELEMETRY=0. What is sent →
