GoBadge Dynamic: From Module Stats to Universal Badges

GoBadge v2 moves from three fixed Go module endpoints to a dynamic badge API.

It can pull values from any HTTPS JSON source, including nested keys and multiple fields.

The service now renders customizable badges from general API data, not just Go module stats.

This makes GoBadge useful for GitHub, npm, PyPI, Crates.io, Docker Hub, and other JSON-backed metrics.
