Runsight

Runsight is an open-source, self-hosted workflow engine designed specifically for AI agent development. It enables developers to design, execute, and evaluate agent workflows using YAML configuration files that integrate seamlessly with Git version control.

Key features include:

• Canvas and YAML duality: Two synchronized views of the same workflow with visual canvas editing and YAML code editing
• Per-run cost tracking: Real-time cost monitoring with hard budget caps to prevent overspending
• Built-in evaluation framework: Assertions on block outputs, transformation hooks, and regression testing
• Git-native workflows: Every workflow is a YAML file in your repository with full version control capabilities

This tool targets developers and teams building AI agents who need reproducible, version-controlled workflows with cost transparency.
