Open VSX vs Marketplace Packaging Checklist

2026-09-14

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
