Eclipse Foundation launches Open VSX Managed Registry

The Eclipse Foundation introduced Open VSX Managed Registry as a foundation-operated managed service for the Open VSX extension registry. The service is designed to support organizations that use Open VSX in production settings where defined service levels and operational assurances apply.

Open VSX is a vendor-neutral extension registry for tools built on the VS Code extension API. It serves an ecosystem that includes AI-native IDEs, cloud development environments, and VS Code-compatible platforms, with named examples such as Kiro by Amazon Web Services (AWS), Google’s Antigravity, Cursor, VSCodium, Windsurf, IBM Bob, and Ona (Gitpod).

The managed registry includes a 99.95% uptime SLA with service credits, defined usage tiers, and support tiers. The service also uses a multi-region architecture with European-based infrastructure, includes 24/7 monitoring with tier-based incident response, uses identity-based access controls and usage dashboards, and supports capacity planning. Open VSX remains freely accessible, with paid tiers applying when tools embed Open VSX at production scale.

Open VSX now serves more than 300 million downloads per month, with peak daily traffic exceeding 200 million requests. The registry hosts over 12,000 extensions from more than 8,000 publishers, and it is available immediately. “Open VSX has become critical infrastructure for modern developer platforms,” said Mike Milinkovich, Executive Director of the Eclipse Foundation. “As AI-era usage drives exponential growth in traffic and operational complexity, commercial adopters require defined service levels and operational guarantees. Open VSX Managed Registry provides enterprise-grade reliability and accountability while preserving open governance, vendor neutrality, and free access for developers.” “AI agents have changed the economics of developer infrastructure,” said Thabang Mashologu, Chief Marketing Officer & Head of Products at the Eclipse Foundation. “Registries that were designed for human-scale usage must now operate at machine-scale traffic levels. When commercial platforms depend on Open VSX at production scale, the underlying infrastructure must meet enterprise expectations. This managed service delivers SLA-backed reliability and predictable scaling, while ensuring Open VSX remains open and freely accessible to individual developers and open source projects.”
