ontrackd puts a small comment bar on your dev server and your previews. People point at an element on the page and say what should change. Each comment knows the file and line behind that element, not only a spot on the screen.
The dashboard collects every comment for a project, from you, your team and the reviewers you invite. The comments reach your agent directly: it asks for them over MCP, gets the exact lines to edit, makes the changes, and marks each comment resolved.
Fastest way: ask your agent
Paste this into Claude Code, Cursor or any coding agent working in your project:
Install and configure ontrackd in this project: run npx @ontrackd/feedback init and follow what it prints.
It asks who will comment, then installs the package, adds it to your build and connects your agent. To set it up by hand instead, start with the Quickstart.
