PySpur

PySpur is an AI agent builder and visual playground that enables engineers to build, test, iterate, and deploy agentic workflows using Python or a drag-and-drop UI.

PySpur provides a development environment for AI engineers to build and manage agentic workflows. Users construct agents either through Python code or a drag-and-drop user interface. The platform focuses on reliability by allowing users to define specific test cases, run iterative evaluations, and identify failure points within workflows. Each agent can be exported as a JSON file, facilitating version control via git and team collaboration. The software is available under an Apache 2.0 license and supports deployment to both cloud and on-premise environments.
