Theme Updates & Maintenance
How the platform delivers theme improvements after you customize, without forcing you to rebuild from scratch.
Versioned theme releasesEach theme has a version with a changelog you can read before upgrading.
Per-theme semver + changelogs
Browser 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.
08
Embeds & Integrations
Sell from outside your storefront — checkout pop-ups embedded on third-party sites, Discord landings, Telegram, blog posts.
Embeddable checkout (script-tag)Drop a single <script> tag on any page; clicking a button opens a Shoppex checkout modal in an iframe.
Visual design variants for the embedPick how the modal looks against your brand without writing CSS.
4 variants (current, clean-light, clean-dark, v2)
Single style with theme toggle
Light, Dark, Auto, Default theme modes
Group-picker embed (multi-product selection)A single embed that lets the buyer pick from a curated product group inside the modal.

Trade-offs
Where the alternatives win
Three places we don’t lead today, why we made that choice, and when a competitor is actually the right pick.
01
Komerza sells email broadcasts as a paid add-on. We don’t ship them at all.
Komerza’s email marketing—campaigns, recipients, domains, suppressions—is a paid upsell, not part of their free tier. Shoppex bets on Telegram instead, where digital-goods buyers actually live. If your customers expect newsletters in their inbox andyou’re willing to pay for it, Komerza covers that lane.
02
Komerza’s embed speaks the buyer’s language. Ours doesn’t.
Komerza’s checkout embed auto-detects the buyer’s browser locale and renders in their language. Shoppex ships English-only today on the embed. If your customers are spread across non-English markets, Komerza wins this one.
03
Komerza lets you bring your own framework. We curate React themes.
Komerza ships a browser IDE that supports React, Vue, Svelte, Solid, and others. If your priority is total framework freedom and you want to write a storefront from scratch, Komerza is more flexible. Shoppex ships six production-grade React themes with a managed update pipeline—you trade some choice for staying patched.
04
SellAuth and Komerza both have a 0 USD free tier. Shoppex doesn’t.
If you’re testing an idea on near-zero revenue, the competitors are free. Shoppex starts charging at the first sale. Above 19,900 EUR/mo, our 199 EUR/mo cap kicks in—you stop paying more, and most features behind their paid plans (9.99 USD SellAuth, 19.99 USD Komerza) are already included on Shoppex.
SellAuth has shipping zones for physical goods. Shoppex is built for license keys, files, services, dynamic delivery, and subscriptions. If your catalog is physical, SellAuth fits better.
We audited 91 features. Shoppex won most of them.
No plan tiers. No upgrades. No surprises. The features Komerza and SellAuth charge for, or don’t ship at all, are included on day one.
