Language Bindings

liblsl is a C library with a C++ wrapper (both documented in the liblsl documentation). Other languages use it through bindings. The official bindings are maintained under the labstreaminglayer GitHub organization. Community bindings are maintained by others; they are listed here because we know of them, not as an endorsement, and their completeness and upkeep vary (the year of the last change is given as a hint). To add one, edit this page and open a pull request.

Official

Language	Project	Notes
C / C++	liblsl	The library itself: lsl_c.h and the header-only lsl_cpp.h.
Python	pylsl	pip install pylsl; ctypes wrapper around liblsl.
MATLAB	liblsl-Matlab	MEX wrappers.
C#	liblsl-Csharp	A single file (LSL.cs) using P/Invoke; you provide lsl.dll.
Unity	LSL4Unity	Unity package with the C# binding and the native plugin.
Unreal Engine	plugin-UE4	Also on the Unreal Marketplace.
Java	liblsl-Java	JNA wrapper; also used on Android.
Rust	liblsl-rust	crates lsl / lsl-sys (last published 2020).
Android	liblsl-Android	Older Android Studio build of liblsl and the Java binding (2020). For new apps, build liblsl from your app’s CMakeLists.txt (see Building liblsl).
Other (SWIG)	liblsl-Generic	SWIG interface files for generating further bindings (2018).

Reimplementations

These implement the LSL protocol themselves instead of using liblsl. They may differ from liblsl in behavior and compatibility; check how they are tested before relying on them.

• Rust: labstream (exports liblsl’s C API), rlsl (C API, Python bindings and a WebSocket bridge)

• Swift: SwiftLSL (receiving only)
