About

BrickLink Classic Helper — Prototype

This extension is an early prototype and is expected to contain bugs. If a future BrickLink update breaks it, the helper can be quickly disabled from its browser-toolbar menu to restore BrickLink’s normal interface.

BrickLink Classic Helper is an unofficial browser extension that provides a classic-style interface for adding items to a BrickLink store inventory.

It is intended for sellers who prefer the layout and workflow of BrickLink’s older add-item pages while still using BrickLink’s current website, catalog information, and inventory systems.

Main features

* Support for parts, minifigures, sets, instructions, original boxes, and gear
* Catalog category and item selection
* BrickLink color options and catalog images
* New and used condition options
* Quantity, price, cost, remarks, description, bulk quantity, sale percentage, stockroom, and reserved-buyer fields
* Duplicate-inventory checking
* Custom-image upload support
* Review and completion screens
* Temporary local caching to preserve form information and improve loading times
* A browser-toolbar switch that can disable the helper and restore BrickLink’s normal interface

**Superlots are not currently supported.**

Important prototype warning

This extension is an early prototype and contains known bugs.

It has primarily been developed and tested with standard parts, minifigures, and similar frequently listed items. These items should generally work, but uncommon catalog types, unusual item configurations, and special situations may not behave correctly.

BrickLink can change its website, catalog pages, or inventory submission systems at any time. Such changes may partially or completely break the extension until it is updated.

If this happens, open the extension’s browser-toolbar menu, turn the helper off, and reload the page. BrickLink’s standard interface will then be available.

Nothing is guaranteed to work. Always carefully review the item number, color, condition, quantity, price, description, remarks, and all other information before saving and after submitting an inventory item.

Privacy

BrickLink Classic Helper does not include analytics, advertising, or third-party tracking.

The extension does not send personal information to the extension’s developer, advertisers, analytics providers, or unrelated third parties.

Its enabled or disabled preference is stored locally using the browser’s extension storage. Temporary form state and catalog information may also be cached locally in the browser to support the extension’s functionality.

To perform its features, the extension reads information displayed on BrickLink pages and communicates with BrickLink’s own website, image servers, and inventory systems while you are signed in. BrickLink’s own terms, privacy policy, and data practices continue to apply.

Independent project

BrickLink Classic Helper is an independent, unofficial community project.

It is not affiliated with, sponsored by, approved by, or endorsed by BrickLink, the LEGO Group, or any of their affiliates.

BrickLink and LEGO are trademarks of their respective owners. Their names are used only to identify the websites and services with which this extension is designed to work.
