Looking for the best Shopify section apps? Most write .liquid files into your theme, so they share the same theme-update trap as hand-coded sections. SectionGuard keeps your custom sections in the app instead — here's the factual difference between the two approaches.
Section Store, Puco Sections and most catalog-style section apps are honest, useful tools. When you add one of their sections, the app copies its .liquid (and often CSS/JS) into your theme's files. From that moment the section is part of your theme — which is exactly why it keeps working after you uninstall the app, and exactly why a theme update can overwrite or freeze it.
SectionGuard takes the other path. Your sections live in the app and render through a single Theme App Extension block — an app block you place in Shopify's native theme editor. Nothing of yours is copied into the theme, so a theme update has nothing of yours to overwrite. The trade is the mirror image: your sections stop rendering if you uninstall, because the theme never held the code.
Neither model is universally better. They optimize for opposite things: surviving an uninstall versus surviving an update. Pick based on which event you expect to happen more often.
Section Store, Puco Sections and similar apps write their section files directly into the theme you're editing. The section becomes part of that theme's code.
Your section lives in the app and is stored as a Shopify metaobject — it renders through a Theme App Extension block. No .liquid, CSS or JS of yours is copied into the theme.
The best Shopify section apps differ on the details, but the trait that decides your next theme update is where the sections live. Everything else follows from that.
| SectionGuardSections live in the app | File-based section apps | Hand-coded into the theme | |
|---|---|---|---|
| Sections live in… | The app | Your theme files | Your theme files |
| Theme update | Everything survives | Lost or frozen | Overwritten |
| Theme switch | Place one block | Re-insert each section | Rebuild by hand |
| Custom HTML / CSS / JS | Full editor | Varies by app | Full, in theme files |
| Live metafield tokens | Built in | Varies by app | Hand-wired Liquid |
| Versions + restore | Built in | None | None |
| Survives uninstall | no | yes | yes |
| No write_themes scope | yes | no | no |
Fair is fair: file-based sections keep working after you uninstall the app — ours live in the app, so they don't. That's the trade for surviving every theme update. If uninstalling is more likely for you than updating your theme, a file-based app may fit you better.
If you take vendor theme updates, redesign, or move between themes, file-based sections are the fragile part. SectionGuard keeps them in the app so an update can't touch them.
If you mainly want to drop in pre-designed blocks and rarely update the theme, a catalog app like Section Store can be the quicker route. Different job, different tool.
If you build bespoke sections with your own HTML, CSS, JS and metafield data, SectionGuard gives you the full editor plus versions and restore — without any code landing in the theme.
