# Open VSX vs Marketplace Packaging Checklist

## Direct answer

Treat Marketplace and Open VSX as two releases of the same extension: version lockstep, identical README claims, separate publisher auth.

## Checklist

- bump version once, publish twice
- verify `publisher` and package name match storefronts
- test install on both channels
- keep RTL claims honest to what the preview actually does
