recovercheck

A Go static analysis tool that finds goroutines created without panic recovery logic.

Why?

Unhandled panics in goroutines crash your goroutines. recovercheck helps you catch these before they reach production.

// ❌ Bad - will crash the program
go func() {
    panic("oops")
}()

// ✅ Good - panic is recovered
go func() {
    defer func() {
        if r := recover(); r != nil {
            log.Printf("recovered: %v", r)
        }
    }()
    panic("oops")
}()
