Open source has undergone a profound transformation in the last few years, shifting from a fringe movement to the central control plane for AI and modern infrastructure. While headlines focus on proprietary AI models, the quiet work of standardizing the layers beneath—Kubernetes, observability, networking, and platform engineering—has accelerated. This evolution is driven not by altruism but by strategic corporate investment aimed at shaping the defaults and standards that everyone else will use.
Open Source Becomes Dull and Essential
The romantic notion of open source as a developer-led revolution has given way to a more mundane reality: open source is where infrastructure hardens into standards. The Cloud Native Computing Foundation (CNCF) now hosts over 230 projects with more than 300,000 contributors worldwide. Its 2025 survey found that 98% of organizations have adopted cloud-native techniques, and 82% of container users run Kubernetes in production. GitHub’s Octoverse report for 2025 recorded 1.12 billion contributions, over 180 million developers, and 518.7 million merged pull requests. The Apache Software Foundation remains steady with 9,905 committers across 295 projects and 1,310 software releases in fiscal year 2025. These numbers confirm that open source engagement is alive and well, but concentrated in the infrastructure layers that matter most for AI and scale.
Who Contributes and Why
The list of top contributors reveals a clear corporate strategy. According to CNCF Devstats for 2025, Red Hat led with 194,699 contributions, followed by Microsoft (107,645) and Google (91,158). Independent contributors came fourth at 52,404, proving that community still plays a role, but the center of gravity is unmistakably corporate. Red Hat’s dominance stems from its Kubernetes-centric product OpenShift, making its contributions a direct product strategy rather than charity. Microsoft, once an open source skeptic, now invests heavily in projects like OpenTelemetry, which saw a 39% rise in commits and a contributor base growing from 1,301 to 1,756 in a single year. This is not philanthropy—it’s a land grab for observability standards. Splunk and other vendors similarly invest to normalize interfaces and shape operational assumptions.
Cilium, a networking and security project, saw contributing companies rise 90% after joining CNCF, from 533 to 1,011, and individual contributors jumped from 1,269 to 4,464. Google, Datadog, and Cloudflare expanded their contributions as the project matured. Cilium sits at the intersection of networking, observability, and security—precisely the categories that become mission-critical when workloads are distributed, latency-sensitive, and expensive. Nvidia, despite its massive cash reserves, ranked 14th in Kubernetes contributions with 5,892 contributions and has open sourced the KAI Scheduler, a Kubernetes-native GPU scheduler. Nvidia also describes itself as a key contributor to Kubeflow. This indicates that even dominant hardware companies recognize the need to influence the orchestration and workflow layers that determine how their chips are used in real-world AI systems.
AI Driving Open Infrastructure
AI workloads are accelerating the importance of open infrastructure. CNCF reports that 66% of organizations hosting generative AI models now use Kubernetes for some or all inference workloads, calling Kubernetes the de facto operating system for AI. This claim is plausible given the need for scalable, portable, and observable infrastructure for training and inference. Kubeflow, built on Kubernetes, is becoming central to AI workflows. By contributing to these projects, companies ensure that AI systems remain governable, visible, and efficient—qualities that proprietary stacks often lack. The open source model allows organizations to inspect, influence, and adapt the infrastructure to their specific needs, reducing lock-in and fostering innovation.
The shift is not without trade-offs. Open source is increasingly about control—not proprietary control, but control over the layers where ecosystems harden into standards. The companies investing upstream are not doing it out of civic virtue but because whoever shapes the substrate typically gains leverage over everything built on top of it. This pragmatic approach has made open source more essential than ever, but also less romantic. The era of open source as a moral crusade is over. It has been replaced by a cold, strategic calculus where investment in open source is a necessary cost of doing business in the cloud-native and AI age.
In conclusion, open source has not died; it has matured. It has become the control plane for AI and modern infrastructure. The numbers and trends from CNCF, GitHub, and Apache confirm that engagement is shifting to the most impactful layers. AI is making open infrastructure more important because few organizations want to build their future on opaque, inescapable platforms. The future of open source is dull, essential, and heavily funded—exactly what the industry needs to support the next wave of AI innovation.
