# llgo Go compiler based on LLVM. Source: [Console review]() Website: [https://github.com/xgo-dev/llgo]() Profile updated: 2026-10-16 Category: [Operating systems]() ## Supported tech stack Research checked: 2026-10-11 ### Integrates with - C (Language) - C++ (Language) - Go (Language) - JavaScript (Language) - Objective-C (Language) - Python (Language) - Swift (Language) Source: [Research source]() Documented compatibility; coverage may be incomplete. Written in describes implementation, not user-project language support. Go compiler targets LLVM and provides C ABI interoperability with C/C++, Python, JavaScript, Objective-C and Swift. ## Console’s review — 2026-09-03 Reviewed: 2026-09-03 Author: [David Mytton]() Citation: [This review]() ### 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. ### Tradeoffs 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. This review reflects Console’s assessment at publication on 2026-09-03. Features and limitations may have changed since the review date. ## Is llgo a fit? Based on [Console’s review published on 2026-09-03](). Summary updated: 2026-10-16 ### Who it’s for Developers who need to interface with other languages ### Why consider it Allows FFI performance without FFI ### Keep in mind Goroutines are heavier due to mapping to OS threads [Selection criteria]() · [About Console]() · [Browse tools]()
