Make design changes
from 
Slack.from 
WhatsApp.
Agent48 connects Slack or WhatsApp to the coding agent you already use. Anyone on the team can send a screenshot, ask for a change, and try the preview on their phone — engineers just get one tidy pull request.

This welcome screen feels cluttered — can we make the Continue button easier to spot?

On it! I'll tidy this screen up and drop a preview here in a few minutes.
Agent48 2:19 PM
Your preview is ready — open it on your phone and have a tap around.

Love it. Go ahead! 🎉
No tickets to write.
No engineers to chase.
No design files to decode.
Bring your own agent
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.

GrokHow it works
From “this looks off”
to “ship it.”
Keep scrolling — the phone walks you through it.
Show it
Screenshot the screen you want changed and send it in Slack or WhatsApp. Add a voice note or a line of text — whatever's fastest.
Agent48 builds it
It makes the change in a private copy of your app, so nothing you have today is touched while it works.
Try it for real
A preview lands back in the same thread. Open it on your phone and tap around — it's your actual app, not a picture of it.
Say the word
Want changes? Just reply. Happy? Say “go ahead” — approved tweaks are bundled into one clean pull request for your engineers.
Get started
One command.
Five questions.
Point it at your app and your Slack or WhatsApp, and you're off. Setup takes about a minute. Everything runs on your own machine, and nothing goes live without your go-ahead.
Works on macOS with Node.js 24+ and your coding agent — Claude Code, Codex, or Grok.
