Why ExtensionBazaar?
Each host has a native gallery (Cursor → Open VSX / Extensions view; VS Code → Visual Studio Marketplace). ExtensionBazaar bridges the other galleries the host leaves out — without replacing the built-in Extensions UI.
How to open it
| Entry | Where |
|---|---|
| Activity Bar | ExtensionBazaar icon — Browse markets, History, Find updates, Help, License |
| Status bar | Bazaar on the left — opens the companion (gallery browser + Support) |
| Command Palette | ExtensionBazaar: Open, Open Companion (active market), … |
Typical flow
- Click status bar Bazaar (or Browse → Visual Studio Marketplace / Open VSX).
- Browse an extension details page in the gallery browser.
- If Install does not appear: copy the address bar (Ctrl+L, Ctrl+C) — Support picks up the details URL.
- Click Install in {host} and confirm (Microsoft-restricted extensions show an extra warning when known).
- Find updates checks only extensions you installed via Bazaar (network scan starts when you click Check).

Disclaimer (freeware)
- No liability — provided AS IS; ready-4-it accepts no liability for damage, data loss, failed installs, or third-party extensions (to the maximum extent permitted by law).
- No support — freeware includes no support entitlement or SLA.
- Acceptance — by installing or using ExtensionBazaar you agree to these terms and the EULA (
LICENSE.txt). Features unlock only after the in-product Accept confirmation. - Marketplace display only — gallery sites open in the host browser as official pages; ExtensionBazaar does not rewrite that view and does not embed marketplaces in an iframe.
- Sideloaded VSIX packages may not update via the host’s native gallery updater.
- Some Microsoft-published extensions refuse to run outside official Microsoft editors — ExtensionBazaar warns before install when known.
- Engine mismatch → highest host-compatible version (or a clear error).
