Sourcemeta Studio is published and maintained by the official Sourcemeta organization, the team behind open-source JSON Schema tooling used in production by developers and companies worldwide.
At the time of writing, the Visual Studio Code Marketplace Verified Publisher badge has not yet been applied to this extension. Publisher verification is a Microsoft-managed, administrative process that is independent of an extension’s code quality, security posture, or maintenance status, and can take time even for established open-source organizations.
This extension is actively maintained by the Sourcemeta team, and all releases are built from the same public repositories that power Sourcemeta’s other open-source projects.
