Theme Updates & Maintenance

How the platform delivers theme improvements after you customize, without forcing you to rebuild from scratch.

FeatureShoppexSellAuthKomerza
Versioned theme releasesEach theme has a version with a changelog you can read before upgrading.Per-theme semver + changelogsBrowser IDE: you own the code
3-way merge on theme upgradeWhen the framework ships a new version, your customizations are merged file-by-file using SHA checksums. You see clear conflict markers, never a forced overwrite.
Hotfix auto-applyBugfixes inside framework-only paths apply automatically; you never have to manually click "update" for security patches.
Pre-flight build validationEvery upgrade runs a real `bun install + build` in a sandbox before being applied. If it fails, the upgrade is blocked, not pushed broken.
Rollback with 30-day backupsEvery upgrade snapshots your theme to R2. One click restores the previous state.

Embeds & Integrations

Sell from outside your storefront — checkout pop-ups embedded on third-party sites, Discord landings, Telegram, blog posts.
