Interesting tools

Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.

llgo

Go compiler based on LLVM.

What we like

Source remains compatible with Go, but uses the C Application Binary Interface (ABI) to allow interfacing with other languages (JS, Python, C/C++). FFI performance without FFI. Supports the latest Go 1.27 syntax and cgo, but without cgo. Goroutines map to OS threads. Native, Wasm, and embedded targets.

What we don't like

Goroutines map to OS threads, which are heavier than lightweight goroutines. Garbage collection is more conservative and different per target, so it needs benchmarking vs pure Go.

Tailcat

Tailscale without Tailscale.

What we like

Uses Tailscale’s data plane without using the control plane i.e. connect endpoints without needing a Tailscale account. No IPs, no users, no controls - great for direct connectivity. Works as a CLI or a Go package.

What we don't like

You have to run your own DERP server for true Tailscale independence.
