Plannotator

Plannotator lets you annotate and review an agent's plans and code diffs in a visual page, share them with a team, and send the feedback back to the agent in one click. It is Apache 2.0 licensed, built by backnotprop, and has 9.8 thousand stars. The README installs it with curl -fsSL https://plannotator.ai/install.sh | bash, with a minimal variant, and mentions a separate terminal version. Piping a script into a shell means trusting the script, so read it first if that matters to you. We think the idea fits the gap between letting an agent run and reading every line: a plan you can mark up is easier to correct early. Sharing with a team implies a hosted piece, so check what is stored before using it on private code. Last push 31 October 2026. We have not used it.
