A delightful avatar generator by the folks at Draftbit. Try it online at https://personas.draftbit.com

Personas is built with ReScript, React 18, and Vite. You'll need Node 22+ (see .nvmrc) and Yarn 4 (via corepack enable).

• yarn installs dependencies
• yarn re:watch starts the ReScript compiler in watch mode
• yarn dev starts the Vite dev server (run alongside re:watch)
• yarn build produces a production build in dist/
• yarn preview serves the production build locally

The site deploys to Cloudflare Workers as a static-assets Worker. Pushes to master deploy automatically via GitHub Actions (.github/workflows/deploy.yml), which requires the CLOUDFLARE_API_TOKEN and CLOUDFLARE_ACCOUNT_ID repo secrets. You can also deploy manually with yarn deploy.

Personas is fully addressable by URL — see llms.txt for the concise spec.

• Avatar page: https://personas.draftbit.com/?hair=Mohawk&hairColor=F2C94C&eyes=Hearts — style params (hair, facialHair, body, eyes, mouth, nose, accessories) and hex color params (skinColor, hairColor, facialHairColor, bodyColor, accessoriesColor, bgColor)
• Valid options: GET /api/options (JSON)
• Avatar image: GET /api/avatar.svg?<same params> (also ?code=<shortcode> or ?random=1)
• MCP server: POST /mcp — tools list_avatar_options, generate_avatar, random_avatar (e.g. claude mcp add --transport http personas https://personas.draftbit.com/mcp)
• Short share links (personas.draftbit.com/<code>) are a stateless base64url encoding of the avatar config, which makes the option arrays in src/data/config.json append-only — never remove or reorder entries, only append.

• We were exploring Reason/Rescript
• We wanted to put together an inclusive avatar generator for placeholders and profile photos
