It implements the camo pattern: a web application rewrites remote image URLs into signed proxy URLs, and the proxy fetches and serves those images over TLS to avoid mixed-content warnings. ### Project history The project was announced to the Go community in July 2012 as a Go version of GitHub's Camo server. Its README keeps that lineage explicit by describing go-camo as a Go version of a camo server and by comparing it with the original atmos/camo project. ### Adoption history go-camo fit an operational niche for sites that hosted HTTPS pages while allowing user-supplied image URLs. Its significance came less from broad framework adoption and more from giving operators a static Go binary, native TLS and HTTP/2 support, HMAC URL validation, and deployment guidance for process supervisors, Heroku, containers, and CDN-fronted installations. ### How it is used Practitioners deploy go-camo beside a web application. The application signs the original image URL with an HMAC key and emits a go-camo URL; go-camo validates the signature, decodes the target URL, fetches the remote image, and streams it back. The README also documents operational controls such as `GOCAMO_HMAC`, HTTP proxy variables, private-address rejection for SSRF-style risk reduction, allow/deny filters, and supervisor-based production operation. ### Why package nerds care For package maintainers, go-camo is the kind of small network daemon that benefits from binary distribution: a single executable plus man pages and service-manager examples. Its packaging in Homebrew and Nix makes the image-proxy pattern installable without a Node or Ruby runtime. ### Timeline - 2012: The GitHub repository was created. - 2012: The author announced Go-Camo on golang-nuts as a Go version of GitHub's Camo server. - 2013: v0.1.x releases were published on GitHub. - 2026: v2.7.x releases showed ongoing maintenance of the Go daemon line. ### Related projects - atmos/camo - GitHub Camo - Stripe Smokescreen ### Sources - - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** go-camo - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - go-camo: normalized package name match | nixpkgs package indexes: pkgs/by-name/go/go-camo/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [go](https://www.automicvault.com/pkg/brew/go/) - Build dependency declared by Homebrew. - [ghostunnel](https://www.automicvault.com/pkg/brew/ghostunnel/) - Shares av.db curated category or tags: cli, networking, proxy, security, tls. - [glider](https://www.automicvault.com/pkg/brew/glider/) - Shares av.db curated category or tags: cli, go, networking, proxy. - [gost](https://www.automicvault.com/pkg/brew/gost/) - Shares av.db curated category or tags: cli, go, networking, proxy. - [haproxy](https://www.automicvault.com/pkg/brew/haproxy/) - Shares av.db curated category or tags: cli, http, networking, proxy. - [mihomo](https://www.automicvault.com/pkg/brew/mihomo/) - Shares av.db curated category or tags: cli, go, networking, proxy. - [obfs4proxy](https://www.automicvault.com/pkg/brew/obfs4proxy/) - Shares av.db curated category or tags: cli, go, networking, proxy. - [privoxy](https://www.automicvault.com/pkg/brew/privoxy/) - Shares av.db curated category or tags: cli, http, networking, proxy. - [proxyfor](https://www.automicvault.com/pkg/brew/proxyfor/) - Shares av.db curated category or tags: cli, http, networking, proxy. - [tun2proxy](https://www.automicvault.com/pkg/brew/tun2proxy/) - Local metadata places this package in an adjacent workflow.
