Glean
Glean is a system for working with facts about source code. You can use it for:
-
Collecting and storing detailed information about code structure. Glean is designed around an efficient storage model that enables storing information about code at scale.
-
Querying information about code, to power tools and experiences from online IDE features to offline code analysis.
Status
Glean is pre-release software. There are many rough edges; there are only two language indexers available initially (JavaScript and Hack); the build system is not as smooth as we would like. However, we want to make it available for you to experiment with and contribute to.
We'd love to hear feedback! If you run into problems or have suggestions please file an issue.
Language coverage
There is currently support for:
Indexers for these languages exist but aren't in the open source release yet; we hope to make these available in the future:
- Python
- C++
- Objective-C
- Java
- Rust

Docker demo
For demo of the react codebase with hyperlinks powered by glean run
docker run -ti -p8888:8888 ghcr.io/facebookincubator/glean/demo
Try out on your own codebase with a .flowconfig by running
docker run -ti -p8888:8888 -v __YOUR_CODE_DIR__:/glean_demo/code ghcr.io/facebookincubator/glean/demo
Play round using the glean binaries in a shell by running
