r3 helps you review coding agent artifacts: HTML pages, Markdown docs, and code diffs. See what's built, comment on any element, passage, or line, and send it back to the agent to steer the next revision. Runs locally, open source, works with any agent.

Hey folks! I'm a big fan of Claude Artifacts, but whenever I hopped over to another coding agent, I'd miss them. Nothing else had anything like it. So I put together r3 for myself. It lets me look over whatever my agents spit out, drop comments right on the bits I care about, and make sure what they build is actually what I had in mind. It works with any coding agent.
These days r3 shows up in almost all my coding sessions. In one week, my agents created 32 artifacts and I left 324 comments on them. And it's not just for reviewing. I also have my agents build little HTML pages to explain stuff to me, like how a library works under the hood. Give r3 a try, I'd love to hear your feedback!
