From one sentence to a working app.

This one’s live: pan the canvas, drag the windows, spawn agents, run tasks from the Forge board, skim the diff in Code Review, and start a dev server to preview the site.

“one sentence each”

Start a loop with one sentence.

Type loop: run the test suite every hour and you’re done. JustBridge adds the task to your board on schedule, and your agents pick it up automatically. No agents running? It spawns one for you. Six ready-made presets included.

MCP servers
Give every agent the same tools: each server is added to spawned agents’ MCP configs automatically (Claude, Codex, Cursor, Gemini).
GitHubnpx -y @modelcontextprotocol/server-github
Postgresnpx -y @modelcontextprotocol/server-postgres
Playwrightnpx -y @executeautomation/playwright-mcp-server
Name — e.g. GitHubCommand — e.g. npx Add server

Add an MCP server once. Every agent has it.

Type a name and a command. That’s it. Every agent you open gets the server automatically, whether it’s Claude, Codex, Cursor, or Gemini. Turn it off, and it’s gone from all of them too.

Vibe coding is a sport now.

Earn Focus XP for time spent building, tasks shipped, and reviews approved. Level up through seven jungle tiers, from Seedling 🌱 to Apex Predator 🐆. Keep your daily streak alive, collect badges, and race your friends on the weekly leaderboard.
