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.

> This specific example, https://jsfiddle.net, is not a monopoly and has many suitable replacements (e.g. https://livecodes.io/, https://liveweave.com). The other two don't even have sidebars... They are suitable replacements in the same way that crickets are a suitable replacement for beef โ It'll get the job done.
