In a significant move for the future of AI-related innovation, Google has donated its Agent2Agent (A2A) protocol to the Linux Foundation. This decision, announced in June 2025, signals a pivotal moment for the development of collaborative AI agents and the broader open source ecosystem.

A New Era of Open Collaboration for AI

The A2A protocol, launched by Google in April 2025, is designed to enable seamless communication and collaboration between AI agents, regardless of their underlying framework or creator. By donating the A2A protocol–including its specifications, SDKs, and developer tools–to the Linux Foundation, Google is relinquishing direct control over the project. This ensures that the protocol’s future development will be managed by a neutral, community-driven organization. The newly formed Agent2Agent project, hosted by the Linux Foundation, will now guide the protocol’s evolution with support and contributions from the likes of Google, Amazon Web Services, Cisco, Microsoft, Salesforce, SAP, and ServiceNow. This move is intended to foster an open and interoperable ecosystem for AI agents, promoting long-term neutrality and collaboration.

Beyond Altruism: A Strategic Play

While the donation is a boon for the open source community, it’s also a calculated strategic move by Google. By placing A2A under the stewardship of the Linux Foundation, Google is seeking to encourage widespread adoption and prevent fragmentation in the burgeoning AI agent landscape. This strategy aims to establish A2A as the industry standard for agent-to-agent communication. A standardized protocol benefits Google by creating a larger, more cohesive market for its own AI and cloud services. The more developers and companies that build on A2A, the more opportunities there are for Google to offer complementary services and integrations.

A Familiar Playbook: Lessons from Kubernetes

This isn’t the first time Google has made such a move. In 2015, Google donated its container orchestration system Kubernetes to the newly formed Cloud Native Computing Foundation (CNCF), a subsidiary of the Linux Foundation. This decision was instrumental in Kubernetes becoming the de facto standard for container management. By open sourcing Kubernetes, Google fostered a massive ecosystem around the technology, which in turn drove significant traffic and business to Google Cloud Platform and other enterprise-focused products. The donation of A2A follows a similar playbook, suggesting Google is aiming to replicate the success of Kubernetes in the AI agent space.

Fueling the Rise of Commercial Open Source

Google’s donation of A2A is a significant tailwind for the commercial open source software (COSS) movement. The creation of a foundational open standard protocol with the backing, but not outright control, of a tech giant like Google lowers the barrier to entry for developers and startups to build innovative commercial products and services. This may potentially give rise to a vibrant ecosystem of COSS startups centered around A2A. These companies can offer specialized agents, optimization technologies, enterprise-grade support, and value-added services, all built on the common foundation of A2A.

The neutral governance of the Linux Foundation provides the stability and confidence that businesses need to invest in and build upon an open source project. This model, where a robust open source core is complemented by a thriving commercial ecosystem, has proven to be a powerful engine for innovation and growth in the software industry.
