Open-source Java framework for building AI agents and LLM apps
Configure any supported provider with an API key and model name, then call chat() for a consistent interface across models.
AgentRunner combines policy and middleware to coordinate models, tools and sandboxes inside a single execution flow.
Reusable, versionable capability definitions that bundle a SKILL.md, scripts and assets, discovered from local directories or remote storage.
Add knowledge retrieval, image generation and OCR pipelines on demand, mixing synchronous and asynchronous execution styles.
Open-source workflow automation built for AI agents and technical teams
Build automations with a visual node editor, then insert JavaScript or Python code nodes when you need custom logic.
Connect to 500+ native services, any REST API via HTTP nodes, and any agent or coding assistant through MCP.
Run agents alongside regular steps, inspect every decision, and add structured inputs, guardrails and human approval steps.
Watch workflows execute live, open past runs, replay a run with mocked data and re-run just the step that failed.
