lcheck is a cli license checker for your project dependencies. It autodetects your language, extract dependencies, identifies missing license information, and detects potential license conflicts.

• Automatic Dependency Detection – Scans dependencies from Cargo.toml, pyproject.toml.
• License Verification – Retrieves license information from public sources.
• Conflict Detection – Highlights incompatible licenses between dependencies.
• Modular Architecture – Designed with separate, well-structured modules for each language, ensuring maintainability and easy extensibility..

To install lcheck, ensure you have Rust installed, then build and install it using:

git clone https://github.com/Roshan-R/lcheck.git
cd lcheck
cargo build --release

To use lcheck globally:

cargo install --path .
