From Dagger: gives each coding agent its own container and git branch so multiple agents work in parallel without interfering, with command logs and the ability to take over the terminal at any time. Connects via MCP; needs Docker and Git. Still experimental.

From Dagger: gives every coding agent an isolated container and Git branch so several agents can work in parallel, and you can view command logs, take over the terminal or discard results anytime. Needs Docker and Git locally; still experimental.

Fast async link checker written in Rust that scans websites and Markdown, HTML and other files for broken links and email addresses, with JSON output, config files and an official GitHub Action, often wired into docs CI.
