Hector
VerifiedDeclarative platform for pure A2A-native AI agents.
What is Hector?
Hector is an open-source, declarative platform centered on A2A-native AI agents. It provides a clean way to describe agents and their interactions without relying on imperative scripting or external orchestration layers.
Agents are defined through structured declarations that the platform interprets directly, enabling consistent A2A messaging and behavior across deployments. This approach reduces boilerplate while keeping the runtime focused on agent-to-agent coordination.
It is intended for developers and teams that need reliable, specification-driven agents in multi-agent environments where interoperability and simplicity matter more than feature-heavy tooling.
What you can build with Hector
A2A system prototyping
Quickly declare and test agents that communicate directly with each other using a shared declarative format.
Interoperable agent networks
Build collections of agents that follow consistent A2A protocols without custom integration code.
Specification-first development
Define agent roles and interactions upfront so behavior remains predictable across different environments.
