Drive from anywhere

iMessage

Connect your phone number once and chat with your agents from iMessage like you would a teammate. Send a task, get a working reply, then a preview link when the agent is done.

• Verified phone numbers only — no random texts can drive your agent.
• Smart agent mode (optional) replaces the canned working-reply with a tool-calling assistant that can answer questions, kick off runs, and link directly to threads.
• Works on any device with iMessage — iPhone, iPad, Mac.

Slack

Add the grasscoding Slack app to your workspace and pick a channel per project. Mention the bot to start a thread, reply in-thread to continue. Threaded conversations map 1:1 to grasscoding threads.

Discord

Same model as Slack — invite the bot, choose a channel, @-mention to start a thread. Useful for indie communities and solo builders who already live in Discord.

WhatsApp

For users outside of iMessage's reach. Verify your number once and you can drive agents from any WhatsApp client on any device.

Web canvas

The project canvas at grasscoding.com/p/<project> is the full-featured way to drive agents. You get the chat, the editor, the terminal, the preview, and the diff in a single layout. The canvas is also where you switch between agents, computers, and branches.

Parallel agents

Clone a computer to run two agents on the same project at the same time without them fighting over files. Common patterns:

• One agent on the feature branch, one on a hotfix on main.
• Two agents racing the same task with different prompts so you can pick the better diff.
• A long-running migration in one VM while you keep iterating in another.
