Go Module Proxy

Mode: 🌐 Public · Domain: proxy.golang.org

Fetch latest version + VCS origin metadata or list every published version tag for a Go module. Hits the unauthenticated Go module proxy (the canonical mirror used by GOPROXY).

Commands

Command	Description
opencli goproxy module <path>	Latest version + VCS origin metadata for a Go module
opencli goproxy versions <path>	Published version tags for a Go module (newest first)

Usage Examples

# Latest released version of a module
opencli goproxy module github.com/gin-gonic/gin
opencli goproxy module golang.org/x/net

# Every published tag, semver-sorted (descending)
opencli goproxy versions github.com/gin-gonic/gin

# Larger window
opencli goproxy versions github.com/spf13/cobra --limit 100

# Include publish times (one extra request per row)
opencli goproxy versions golang.org/x/net --limit 10 --with-time

Output Columns

Command	Columns
module	module, version, publishedAt, vcs, repository, commit, ref, pkgGoDevUrl, url
versions	rank, module, version, publishedAt, url

The module column round-trips between commands; the version column from versions round-trips into goproxy module's version field.

Options

module

Option	Description
module (positional)	Go module path (e.g. github.com/gin-gonic/gin, golang.org/x/net)

versions

Option	Description
module (positional)	Go module path
--limit	Max rows to return (1–200, default: 30)
--with-time	Fetch each version's publish time (one extra request per row, slower but adds the publishedAt column)

Notes

• Module paths must be canonical. Use what appears in your go.mod (host/path/...). The adapter rejects bare names without a host segment.
• Pre-release tags sort lower than releases. The default sort is descending semver; v2.0.0 > v1.10.1 > v1.10.0 > v1.9.0 (NOT alphabetic).
• publishedAt is null by default for versions to keep the request count at 1. Use --with-time only when you actually need the dates.
• module returns the proxy's resolved upstream — vcs (e.g. git), the actual repo URL, the resolved commit hash, and the tag/ref. Useful when a module path doesn't obviously map to a GitHub repo (golang.org/x/net → go.googlesource.com/net).
• No API key required. HTTP 404 / 410 (gone, e.g. retracted modules) → EmptyResultError; 429 → CommandExecutionError.
• Errors. Malformed module path or bad limit → ArgumentError; unknown module → EmptyResultError; transport / non-200 → CommandExecutionError.
