Build to the research,not a guess.

Crux sits in your editor through MCP, so the agent writing the code can read why.

Try it free3 turns free, no sign-up.

In your editor

The research, where the code is written.

  1. Research in Cursor

    Ask why, mid-build, without leaving the file.

    • Cursor
  2. Claude Code and Codex

    Build to findings from the terminal.

    • Claude Code
    • Codex
  3. Acceptance criteria from findings

    Done means what people needed.

Before you build

Settle the shape before the code.

  1. Map the flow first

    Every step and branch, before a line of code.

  2. Draft the page

    Structure and content, ready to build.

Build anywhere.Think in Crux.

Evidence behind every decision, in every tool you build with.
