The Open VSX Registry crosses 300 million monthly downloads as AWS and Cursor back investments in security, reliability, and multi-region infrastructure to sustain critical open-source developer tooling.
The Open VSX Registry has surpassed 300 million downloads per month, marking a major milestone for the open-source extension marketplace and underscoring its growing role as critical infrastructure for modern developer platforms.
Operated under the Eclipse Foundation, the vendor-neutral registry now handles peak daily traffic exceeding 50 million requests, hosts more than 10,000 extensions, and supports over 6,500 publishers. It has become a production dependency for developer platforms serving millions of users worldwide.
The registry powers a rapidly expanding ecosystem of AI-native and cloud-based development environments, including Amazon’s Kiro, Google’s Antigravity, Cursor, IBM’s Bob, VSCodium, Windsurf, and Ona (formerly Gitpod), all built on the VS Code extension API.
As usage scales, major industry players are investing in strengthening the open-source infrastructure. Amazon Web Services has made a strategic investment to improve reliability, traffic management, malware detection, and platform resilience. Cursor is also supporting the registry as extension traffic grows rapidly, reflecting broader industry efforts to sustain shared open-source infrastructure.
To strengthen supply-chain security, the registry has introduced a pre-publication verification framework that can detect namespace impersonation, extension name spoofing, exposed credentials, and known malicious patterns, while quarantining suspicious uploads before publication.
The platform is also transitioning to a hybrid multi-region architecture, with primary production infrastructure hosted on AWS in Europe and an independent on-premises deployment in Canada. All registry data, backups, and telemetry remain within these regions and are encrypted in transit and at rest.
“Open VSX has evolved into foundational infrastructure for the global developer ecosystem,” said Mike Milinkovich. “As adoption accelerates across AI-native and cloud-based development platforms, we are investing to ensure the registry remains secure, resilient, and vendor-neutral. Support from leading commercial adopters reinforces Open VSX as trusted, shared infrastructure.”
