Open Source
The software is 100% open source and distributed under the MIT license.
Best for
Complex, multi-step tasks that benefit from parallel processing, stateful background execution, and isolated subagent contexts.
Not ideal for
Simple, single-step tasks or scenarios where the overhead of managing subagents and file-based context outweighs the functional benefits.
A robust, highly flexible framework for developers needing to build sophisticated, multi-agent systems with infrastructure independence and fine-grained control over execution flow.
Version 1.16.2 introduced async subagent notification metadata and standardized error reporting for file tools; version 1.16.0 added experimental features for async subagent status notifications, webhook support, and execution strategies.
