Gary Tan's tweet about Principal Feed showing 11K views

Three surfaces. One view. Timeline shows when work happened. Feed shows what changed. File City shows where. This is how you understand a codebase in motion.

Principal Feed showing commit activity timeline, feed details, and File City visualization

Explain code in plain English. See what changed, when it changed, and where it happened. No git commands. No terminal. Just the story of what's being built.

Contributor timeline showing collaborator avatars

Discover builders through their work. Not LinkedIn profiles. Not GitHub stars. Watch what people actually build, when they build it, and how they collaborate. A chain of five faces tells a story no resume can.

Software work was invisible.
Not anymore.

For thirty years, understanding what's happening in a codebase meant reading logs, parsing diffs, and asking developers what they did. Principal Feed makes it visible. Live. To everyone.

The feed runs 24/7.

Watch the builder world in real time. No login required. Inside the desktop app, add your private repos and see your team build the same way you watch the world build.
