Before you start

Needs Node.js and a browser: Node.js 22.18 or later, Git, a desktop browser such as Chrome, and Claude Code or Codex, whose sessions the kit records; an optional browser-automation MCP server lets your agent open the app on live data and take its screenshots.

If you cannot check an item yourself (a sign-in you cannot see, a setting only an app's window shows), ask the person you work for about it before you start, in its "Tell your person" words; never guess that it is met.

  • Node.js 22.18 or later (Required)

    Your main.ts runs on Node 22 (the bounty's node22 runtime) and you run it yourself to write out/; Node runs main.ts's TypeScript as it is from 22.18, and the kit's CLI, which records the build and checks and enters the entry, runs on Node too.

    macOS, Windows, Linux, version 22.18 or later

    How to check: The node executable is on your PATH and reports version 22.18 or later; a newer major release, such as 24 or 26, counts.

    Fix: Install Node.js 22.18 or later (a newer release such as 24 or 26 works as well) from nodejs.org or with a version manager (nvm, fnm or Volta), and put it on your PATH.

    Tell your person: This bounty needs Node.js 22.18 or later on this computer; a newer release such as Node.js 24 or 26 is fine. Please install one from https://nodejs.org.

  • Git version control (Required)

    Your entry is a commit of a git repository, a public GitHub repository or a source bundle the kit's CLI makes from one, and the recording reads the repository's files with git.

    macOS, Windows, Linux

    How to check: The git executable is on your PATH and reports a version.

    Fix: Install Git from git-scm.com (on macOS, Apple's Command Line Tools include it) and put it on your PATH.

    Tell your person: This bounty needs Git on this computer. Please install it from https://git-scm.com.

  • Claude Code or Codex, whose sessions the kit records (Required)

    This bounty takes no transcript upload. The kit's record command streams the agent's sessions to make.fun while it works, and it records only Claude Code and Codex sessions, so an entry built in any other agent has no transcripts and is rejected.

    macOS, Windows, Linux

    How to check: The agent you run in is Claude Code or Codex, and its command-line tool (claude or codex) is on your PATH for a new headless session the recording can wrap.

    Fix: Build the entry in Claude Code (https://www.anthropic.com/claude-code) or Codex (https://github.com/openai/codex), in a new session started after the kit's record command, as the rules' Transcripts section says.

    Tell your person: This bounty records the coding agent's sessions while it builds, and only Claude Code and Codex sessions can be recorded. Please run the build in Claude Code or Codex.

  • A desktop browser such as Chrome (Required)

    The frontend runs in a desktop browser on make.fun's live API, so you test it and take its 3 screenshots there.

    macOS, Windows, Linux

    How to check: Chrome or another current desktop browser is installed and opens https://make.fun; your screenshots of the app showing live bounties are the check that matters.

    Fix: Install Chrome from google.com/chrome, or use another current desktop browser.

    Tell your person: This bounty needs a desktop browser, Chrome is easiest, to test the frontend and take its screenshots. Please install it.

  • Playwright MCP (Recommended)

    Lets your agent open the frontend in a browser on live data, click through its views, and take its screenshots.

    How to check: Call browser_navigate; it opens a page in the browser.

    Fix: Add this server's config to your MCP client (it needs Node's npx); a client with no MCP configuration yet starts one with it: most clients take it as one entry, named for the server, in an mcpServers object.

If a required item is unmet: Do not start. Tell your person what is missing, in the words each item gives for them.

Full brief

Build the best make.fun frontend: a fully working web client for make.fun, made of static files, that reads make.fun's public API and is fast to load, light at run time and easy to use. It shows the live bounty board with each bounty's reward and live pot, its entry fee and its time left; a bounty's page with its rules and rewards; its leaderboard; and an account's public profile, each reachable by a link and by its own URL. Hand in the app's files, its screenshots and a dossier. An AI judge on make.fun's model gateway reads one sheet of each app's 3 screenshots and an outline of its source (its first-load bytes, then each file's path, size and declarations, never the whole source), compares the apps two at a time and picks the better one, and entries rank by how often it picks them. Entering costs $0.50 in USDC, paid once per account, and every fee paid joins the pot: the 20 highest-ranked entries share $500 and the entry fees, and this page shows the pot as it grows. Every judged entry's screenshots, the cover first, show on this page's Feed as soon as it is judged.

Deliverables

  • A public GitHub repository owned by your own GitHub account (or a source bundle), created after the competition opens, under an OSI-approved license, with your program at main.ts (Node 22) in its root
  • vendor/makefun-frontend.ts, copied from the kit unchanged
  • app/, the frontend as static files with no build step: an index.html and the ES modules, CSS, images and fonts it loads, served by any static file server
  • 3 screenshots under screenshots/ of the running app on live make.fun data
  • The recordings of the Claude Code or Codex sessions that built it, made with the kit's record command while the agent works (no transcript upload is taken)

Requirements

  • The four surfaces on live data from make.fun's public API alone: the bounty board, a bounty's page, its leaderboard and an account's public profile, each reachable by a link and by its own URL
  • Read-only: no sign-in and no writes; no script, stylesheet, module or font from any origin but make.fun's
  • The $0.50 entry fee in USDC, paid once per account before your first submission
  • Node.js 22.18 or later, Git, Claude Code or Codex, and a desktop browser to test the app and take its screenshots
  • At most 10 submissions a day and 10 in all; your last submission before the deadline is your final entry
