Re: [D] Does Superset 6.0.0 officially support the Extension Framework (.supx)? [superset]

<!-- Answer -->
Yes, I can help! Here's what I found about your Extension Framework questions:
**1. Does Superset 6.0.0 officially support the Extension Framework (.supx)?**
Yes, but it's in **early/experimental form**. The Extension Framework [was introduced in August 2025](https://github.com/apache/superset/pull/31934) and first released with [Superset 6.0.0 in December 2025](https://github.com/apache/superset/pull/36745). However, all extension packages are still at **version 0.1.0rc1** (release candidate status), meaning APIs may change before reaching stable 1.0.0.
**2. Regarding the CLI issues you're encountering:**
The CLI package was [renamed to `superset-extensions-cli`](https://github.com/apache/superset/pull/34883) (not `apache-superset-extensions-cli`). Install it with:
```bash
pip install superset-extensions-cli
```
Commands use `superset-extensions` (with a hyphen):
```bash
superset-extensions init # Create new extension
superset-extensions build # Build assets
superset-extensions bundle # Create .supx file
```
**3. Extension loading configuration:**
[Backend extension loading was enhanced in January 2026](https://github.com/apache/superset/pull/37646). Try these deployment options:
- **For Docker**: Place `.supx` files in `docker/extensions` and set `EXTENSIONS_PATH = "/app/docker/extensions"`
- **For development**: Use `LOCAL_EXTENSIONS = ["/path/to/extension"]` to load from disk
- **Via API**: Upload via `/api/v1/extensions/import/` REST endpoint
**4. Recommended approach for extending Superset 6.0.0:**
For **custom visualization plugins**, you don't need the new Extension Framework. Use the established [ChartPlugin approach](https://github.com/apache/superset/wiki/Semantic-Versioning) documented in the [Community Resource Library](https://github.com/apache/superset/wiki/Community-Resource-Library).
For **UI extensions** (SQL Lab panels, sidebar components, etc.), the .supx framework is the path forward, but given its experimental status, expect some rough edges.
The [comprehensive extension documentation](https://github.com/apache/superset/pull/35217) is available at: https://superset.apache.org/developer_portal/extensions/overview
