BYOT is a native client for OpenCode, the open-source coding agent. Connect to the OpenCode server running on your own computer and drive coding sessions from your iPhone or iPad. SESSIONS Watch replies, reasoning, and tool activity stream live, with syntax-highlighted code, Markdown tables, and inline images. Open a subagent's task to follow its own session. See how much of the model's context window a session uses, plus tokens and cost for each reply. Export a transcript as Markdown or copy it all. COMPOSER Send prompts with photos, files, or files from your server, and mention files with @. Pick commands with /, switch between the Build and Plan agents in one tap, and choose models and reasoning effort from your server's catalog. Type ! to run a shell command directly on your computer and see its output in the conversation. Dictate prompts on-device. Queue follow-ups while the agent works. REVIEW AND CONTROL Review changes as a colored diff for each file, for the whole session or for one turn. Open a terminal to your computer with a key row for Esc, Tab, Ctrl, and arrows. Answer permission requests and questions, undo or redo a turn, fork a session, or compact it. PROJECTS AND SERVERS The session list updates live as sessions start, finish, or need you. Check your branch, MCP and language-server status, and change server settings. Start a session in its own git worktree. Recent sessions and transcripts stay readable offline. Add a server by scanning a pairing code or picking one found nearby, and switch between saved servers. NOTIFICATIONS, SIRI, AND IPAD With the optional BYOT companion on your computer, get notifications for approvals, questions, finished turns, and errors, and choose Allow once or Reject right from the notification. Ask OpenCode or check what needs you with Siri and Shortcuts. On iPad, sessions sit beside the conversation, with keyboard shortcuts. BYOT is available in English and Simplified Chinese. BYOT supports OpenCode 1 and OpenCode 2 beta servers with automatic protocol detection. It shows a feature only when your server supports it. PRIVACY Your server does the work. BYOT renders its responses and sends your instructions over HTTPS. There is no BYOT account or sign-up, and BYOT has no analytics or tracking. Server passwords are stored in the iOS Keychain. Prompts and attachments go to your configured server and the model providers you enable there. Dictation and pairing-code scanning happen on your device. Optional notifications and the computer queue use the BYOT relay for device registration, delivery, and encrypted queued content. See the privacy policy for storage and retention details. Requires an OpenCode server you operate, reachable over HTTPS, for example through Tailscale. Notifications and the computer queue also require the BYOT companion. BYOT is an independent client and is not affiliated with the OpenCode project.

Kanna Mobile is a companion for the Kanna desktop app for macOS. It lets you follow and steer coding-agent tasks from your iPhone while the work runs on your Mac. Kanna Mobile requires a Mac running the Kanna desktop app. It is not a standalone coding-agent host, and it does not run agents on your phone. WHAT YOU CAN DO • See every task across your repositories, grouped by status and activity • Open a task and watch its terminal and agent output stream live • Send follow-up instructions when an agent stops and asks a question • Start new tasks against a repository and agent of your choosing • Review diffs and file contents an agent has touched • Get a notification when a task needs you TWO WAYS TO CONNECT On your local network, pair directly with your Mac by scanning a QR code. No account, no sign-up, nothing leaves your network. Away from home, cloud access relays the connection between your phone and your Mac. Cloud access needs a Kanna account and is currently invite-only — request one at kanna.build/support. BUILT FOR PEOPLE RUNNING SEVERAL AGENTS Kanna gives every task its own git worktree, branch, and agent session, then moves it through a workflow: implement, review, pull request. Kanna Mobile is the window into that from wherever you ff before lunch, an agent stuck on a question, a reviewyou want to read on the train. Kanna works with the coding-agent CLIs you already have installed on your Mac. A NOTE ON WHAT YOU'LL SEE Kanna is a developer tool. It displays repository names, branch names, task prompts, and raw terminal output from your own machine. Requires the Kanna desktop app for macOS, available at kanna.build.
