go-update: Automatically update Go programs from the internet

go-update allows a program to update itself by replacing its executable file with a new version. It provides the flexibility to implement different updating user experiences like auto-updating, or manual user-initiated updates. It also boasts advanced features like binary patching and code signing verification.

Updating your program to a new version is as easy as:

err, errRecover := update.New().FromUrl("http://release.example.com/2.0/myprogram")
if err != nil {
	fmt.Printf("Update failed: %v\n", err)
}

Documentation and API Reference

Comprehensive API documentation and code examples are available in the code documentation available on godoc.org:

Features

• Cross platform support (Windows too!)
• Binary patch application
• Checksum verification
• Code signing verification
• Support for updating arbitrary files

go-update provides the primitives for building self-updating applications, but there a number of other challenges involved in a complete updating solution such as hosting, code signing, update channels, gradual rollout, dynamically computing binary patches, tracking update metrics like versions and failures, plus more.

I provide this service, a complete solution, free for open source projects, at equinox.io.
