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.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.
