# Local development

> Hot-reload custom Python and YAML actions while developing locally against Tracecat: iterate on registry code with fast feedback loops and live workflow runs.

You can test custom actions locally without syncing on every change.

Local registry should only be used for development. Production deployments should use remote [custom registry](/custom-actions/custom-registry) sync.

## Why local development

* Faster feedback loop
* No need to sync on every change
* No need to republish a workflow to use the latest platform and custom actions

## How to enable local development

In your `.env` file, set the following environment variables:

1. `TRACECAT__LOCAL_REPOSITORY_ENABLED` to `true`
2. `TRACECAT__LOCAL_REPOSITORY_PATH` to the path of your local repository e.g. `~/repos/my-local-registry`
3. `PYTHONPATH` to `/app/local_registry:`

```bash theme={null}
TRACECAT__LOCAL_REPOSITORY_ENABLED=true
TRACECAT__LOCAL_REPOSITORY_PATH=~/dev/org/internal-registry
PYTHONPATH=/app/local_registry:
```
