BYOT Coding Agent vs ZyCin · AI SSH Remote Coding

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.

Code from your phone. Connect to your server. On the road, on the train, or putting out a fire — no laptop needed. Tell ZyCin what you want in plain language. It connects to your server over SSH, reads the code, edits it, runs commands and tests, and gets the job done. CORE FEATURES · Conversation as development Describe a task in one sentence. The agent runs the full loop — read files → analyze → edit → verify — with every tool call and code change visible in real time. · Direct SSH to your server Password or private key login. Works with Linux, macOS and Windows (PowerShell). Your code stays on your server — never routed through us. · Multi-protocol file manager Browse and edit over SSH / SFTP / FTP / FTPS / WebDAV, with an icon grid, syntax highlighting and in-place saving. · Switch models freely 175+ built-in provider presets (OpenAI, DeepSeek, Anthropic, Gemini, Kimi and more). Switch models mid-conversation. · Scan for local LLMs Auto-discover Ollama / LM Studio / llama.cpp / vLLM on your LAN — free, offline, and your data never leaves the network. · Image and voice input Send a screenshot so the AI can see the error or the UI. Hold to talk and assign tasks by voice. · MCP extensions Connect MCP (Model Context Protocol) servers to give the agent databases, APIs, Kubernetes and more. · Secure by design Passwords, keys and API keys are stored only in the device secure storage. Writes and command execution ask for confirmation by default, with dangerous commands highlighted. Host fingerprints are pinned on first connect and flagged if they change. WHO IT IS FOR · DevOps and backend engineers who must react to production issues anywhere · Developers who review code and fix bugs on the commute · Indie developers and remote teams NOTES · Bring your own model API key, or use a local model on your LAN. Connecting to a server requires you to have the appropriate access. · New users get a 30-day free trial; afterwards the free tier allows 40 messages per day.
