The coding agents you trust.
In the chat you already use.

Claude Code, Codex, or Grok does the building — Agent48 lets your whole team talk to it from Slack or WhatsApp. No terminal, no new tools to learn.

How it works

From “this looks off”
to “ship it.”

Four steps. No tickets, no meetings, no design files.

  1. 01

    Say what you want

    Anyone on the team sends a screenshot and a sentence in Slack or WhatsApp. That’s the whole request.

  2. 02

    Your coding agent gets a brief

    Agent48 turns the message into a clear brief and hands it to Claude Code, Codex, or Grok — working in a private copy of your app.

  3. 03

    Try the preview

    A few minutes later a preview comes back. Open it on your phone, poke around, ask for tweaks — nobody else sees a thing.

  4. 04

    Reply “go ahead”

    Approved changes land as one tidy pull request. Your engineers review and merge it like any other.

FAQ

Questions,
answered.

A Mac with Node.js 24+, an Expo app, and the coding agent you already use — Claude Code, Codex, or Grok. One command sets up the rest.

No. They message from Slack or WhatsApp exactly like they already do. Agent48 runs on one engineer's machine and handles everything behind the scenes.

Agent48 briefs your coding agent, which makes the change in a private copy of your app. A few minutes later the requester gets a preview to open on their phone. Nothing ships until they say “go ahead.”

Never. Approved tweaks are batched into one tidy pull request, and your engineers review and merge it like any other. You stay in control of what ships.

Slack and WhatsApp today. Your team picks the one they already live in — no new tools to learn.

Agent48 itself runs entirely on your machine — previews are served from it, and changes land as pull requests in your repo. Your coding agent talks to its provider exactly as it does when you use it today.
