Cartographer

Git records what changed. Cartographer records how you got there. It reads the session history a coding agent keeps and turns it into the story of how a project was built, with every point linked to the moment it came from.

What was set up

A developer tool, launched like a product.

Open source doesn't mean unlaunched. Cartographer has everything a paid product would, minus the checkout.

  • The site at codecartographer.dev, with a how-it-works page and a reference for every command.
  • One-line install scripts for Mac, Linux and Windows, served from the site.
  • A public repository under the MIT License, with the documentation kept in step with releases.
  • Domain and DNS.
  • Support for Claude Code, Codex CLI and Cursor, which meant writing for three audiences at once.

What it taught

An honest record is worth more than a tidy one.

Olivia builds with coding agents, and after a few weeks on any project it gets hard to say which decisions did the work and which sent things in circles. Cartographer exists so that record is kept, session by session, without flattery. As a conversation analyst, she reads a session with an agent the way she reads any interaction: turn by turn, with the detail left in.

For founders, the useful bit is this: when Situated Strategies builds something for you, there is a legible account of what was done and why, not just a finished site. That's part of what "handing over the keys" means.

Install instructions and documentation live on codecartographer.dev.
