# CEL Playground
[](https://goreportcard.com/report/github.com/undistro/cel-playground)
[](https://join.slack.com/t/undistrocommunity/shared_invite/zt-21slyrao4-dTW_XtOB90QVj05txOX6rA)
CEL Playground is an interactive WebAssembly (Wasm) powered environment to explore and experiment with the [Common Expression Language (CEL)](https://github.com/google/cel-spec).
It provides a simple and user-friendly interface to write and quickly evaluate CEL expressions.
## CEL libraries
CEL Playground is built by compiling Go code to WebAssembly and includes the following libraries that are available in the environment:
- CEL [extended string function library](https://pkg.go.dev/github.com/google/cel-go/ext#Strings)
- [Kubernetes list library](https://kubernetes.io/docs/reference/using-api/cel/#kubernetes-list-library)
- [Kubernetes regex library](https://kubernetes.io/docs/reference/using-api/cel/#kubernetes-regex-library)
- [Kubernetes URL library](https://kubernetes.io/docs/reference/using-api/cel/#kubernetes-url-library)
Take a look at [all the environment options](eval/eval.go#L26).
## Development
Build the Wasm binary:
```shell
make build
```
Serve the static files:
```shell
make serve
```
