image-gen — Agent's Paintbrush

Marketing site + waitlist API for image-gen, an MCP server that gives AI coding agents a paintbrush (ChatGPT-in-browser image gen, no OpenAI API key).

Built for The Zerops Challenge (WeMakeDevs).

Architecture (3 Zerops services)

The MCP server itself runs on the user's machine. Zerops hosts this website, the API, and Postgres.

Local development

npm install
# optional local Postgres
export DATABASE_URL=postgres://postgres:postgres@localhost:5432/imagegen
npm run dev          # web on :3000
npm run start:api    # api on :3000 (use another PORT if both run)

Deploy on Zerops

# once

zcli login <token>

# create project + services
zcli project project-import ./zerops-import.yml
zcli project scope <project-id>
