Open-source workspace for building, evaluating and shipping AI agents
Assemble agents from templates or from scratch, give them models, skills and tools, and run them from a chat UI, Slack or Telegram.
Wire agents into Notion, GitHub, HubSpot, Slack, Linear, Drive and more over MCP, and swap tools or skills without rewriting the agent.
Score agent outputs, collect feedback and inspect every run with duration, token usage and cost logging so improvements are measurable.
Decide which actions run unattended and which require approval, while credentials stay in a vault your agent can use but cannot read.

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.
