Your web request is now a button. Already have a webhook or a working HTTP request? Make it a button you can use every day. Hey Action keeps the request you need in front of you, without a full API testing workspace. Save one complete action and run it for free. A one-time Pro purchase unlocks unlimited saved actions. SET UP ONCE Enter your request manually, preview a supported cURL command on your device, or try the clearly labeled public example. Importing and saving do not send a request. Test Request and RUN send real requests to your endpoint. RUN IN ONE TAP Choose your saved action with the wheel, then press the large RUN button. Selecting an action does not send a request. Use Edit when you want to change the request. Your everyday action stays front and center, with request details out of the way. Tap the information control beside the request summary to see the full selected action name without running it. Find saved actions by name in a separate list, arrange them in the order you prefer, and remove actions you no longer need. Your main screen stays simple. KNOW WHAT HAPPENED See success or failure, HTTP status, response time, a short response preview when available, and a practical next step for common connection, authentication, request, and server errors. The last main RUN summary remains after reopening the app. It covers the main RUN button, not editor tests or other execution entry points. Response previews are not saved in this history. GO ADVANCED WHEN YOU NEED IT Set the URL, method, headers, and raw request body in the Action Editor. cURL import fills supported fields after an on-device preview. Unsupported options are explained rather than silently ignored. If import fails, keep the original command visible while entering the request manually. • GET, POST, PUT, PATCH, DELETE • Up to 20 custom headers per action • Raw request bodies for supported methods (GET bodies are not supported) • On-device import of supported cURL commands • Clear, categorized results HEY ACTION PRO One saved action includes the complete editor and unlimited runs. A one-time Pro purchase unlocks unlimited saved actions, so you can keep multiple requests ready and switch without entering them again. No subscription. All users, including existing users, can use one action for free. Existing saved actions are not deleted. Choose which action to use for free, or unlock Pro to use all saved actions. Restore Purchases is available from the action list and the Pro screen. Restoring Pro restores your purchase, not deleted action configurations. PRIVATE BY DESIGN No account is required. Action names, URLs, query values, header values, request bodies, response bodies, tokens and API keys are not included in usage analytics. Saved action configuration is stored on the device; executing a request sends it to the endpoint you configured. HELP WHEN YOU NEED IT Open Help & Support from your action list, or contact snj830526@gmail.com. Result notifications are optional for actions run with the main RUN button and require iOS permission. App Settings in the action list contains the global notification preference and permission guidance.

Read full description

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.
