Hermex is a native iPhone and iPad client for your self-hosted Hermes agent. Connect to a reachable Hermes Web UI server, or enable the optional Bot Mode beta to connect directly to a Hermes agent host. Open existing sessions, start conversations, and follow streamed responses, tools, and reasoning as they arrive. Queue, steer, or stop an active run. Review file edits as diffs, browse workspace files, send photos and files, and dictate messages. Manage Kanban boards and cards, browse Tasks, Skills, Memory, and Usage, and choose models, profiles, and reasoning settings. Bot Mode adds a Bots inbox, Desktop sections, reactions, quick replies, approvals, questions, and group rooms. Live Activities keep working runs visible on the Lock Screen and Dynamic Island. Optional notifications let you know when work finishes or needs your attention. The share extension stages content from other apps for you to review and send. Agent execution happens on your configured server, not on the iPhone. Your server owns your conversations, tools, and workspace. Recent sessions and messages may be cached locally for read-only offline viewing; clear that cache from Settings. There is no Hermex-hosted agent backend, tracking, or analytics service. Optional push notifications use an open-source, self-hostable relay. Message previews are encrypted on your Hermes host and decrypted on your iPhone; the relay handles device tokens, notification metadata, and ciphertext, never message text, server URLs, or Hermes server credentials. Push is off until enabled. Hermex has no in-app account creation or in-app purchases. You need your own reachable Hermes server. Not affiliated with Nous Research.

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.
