BYOT Coding Agent vs AI Usage Limits

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.

See how much of your AI allowance you have used, and when it resets, without opening a single dashboard. Every provider hides your remaining quota somewhere different. AI Usage Limits puts them on one screen — and on your Home Screen and Lock Screen. SUPPORTED SERVICES • Claude — session (5-hour) and weekly windows • ChatGPT / Codex — rate-limit windows • Grok — credit usage • Cursor — plan usage • OpenRouter — credit limit and balance WIDGETS • All Providers — everything you have connected, at a glance • Single Provider — one service in full detail, with reset times • Home Screen and Lock Screen sizes, including inline and circular • Every widget shows when it last updated, and flags stale figures rather than passing them off as current TRY IT FIRST Not ready to connect an account? Turn on sample data during setup or in Settings and the app fills itself — dashboard and widgets — with made-up figures so you can see exactly what you would get. BUILT TO BE BORING ABOUT YOUR DATA • No account, no server, no analytics, no ads, no tracking • You sign in on each provider's own page in Safari — the app never sees your password • Credentials are stored in your device Keychain and sent only to the provider they belong to • The app asks for the narrowest access it can. Its Claude token can read your usage and cannot send prompts or spend your allowance • "Delete all data" removes every credential, cached figure and preference from your device • About → Privacy & connections lists exactly what each service is asked for FREE AND OPEN SOURCE No ads, no subscription, no paid tier. The whole app is on GitHub — read exactly what it does and what it sends. PLEASE NOTE This is an independent app and is not affiliated with, endorsed by, or sponsored by Anthropic, OpenAI, xAI, Anysphere or OpenRouter. Except for OpenRouter, it reads usage endpoints those companies have not documented, so a service can change and temporarily stop reporting. Figures are indicative — your provider's own dashboard is authoritative, and you should not rely on this app for billing decisions.
