Runsight โ€” YAML-first workflow engine for AI agents.

Design agent workflows visually. The canvas writes YAML to your filesystem โ€” commit it, diff it, review it in PRs like any other code.

When something breaks at 2 AM, you don't restart and hope. You pause the running agent, edit the prompt, and resume. No redeployment.

What makes it different: โ†’ Git-native. Workflows are YAML files in your repo, not rows in a database. โ†’ Per-run cost tracking. Know what every agent call costs before the invoice arrives. โ†’ Runtime intervention. Pause, inspect, fix, resume โ€” while the workflow is running.

Built for engineering teams who run agents in production and need the same rigor they have for everything else: version control, code review, and the ability to kill a runaway process.

Open source. Self-hosted.

  • Ask HN: How did you learn Regex?
    I read a lot on https://www.regular-expressions.info and experimented on https://rubular.com since I was also learning Ruby at the time. https://regexr.com is another good tool that breaks down your regex and matches. One of the things I remember being difficult at the beginning was the subtle differences between implementations, like `^` meaning "beginning of line" in Ruby (and others) but meaning "beginning of... - Source: Hacker News / almost 2 years ago
  • Building a syntax highlighting extension for VS Code
    As a ruby developer, I was happy to find that VS Code / TextMate grammar files use the same regular expression engine called Oniguruma as ruby itself. Thus, I could be sure that when trying my regular expressions in my favorite online regex tool, rubular.com, there would be no inconsistencies due to the engine inner workings. - Source: dev.to / over 2 years ago
