    Stackpeek Shopify Theme & App Detector

    Stackpeek Shopify Theme & App Detector

    See any Shopify store's theme, apps and trackers in one click

    Stackpeek is a free, open-source browser extension that shows what any Shopify storefront is built on. Click its icon and a side panel names the theme -- with its version, creator and price -- the apps behind the store, grouped by the job they do, and the advertising and analytics pixels the page loads, each named rather than counted as a total. It also exports the store's public product catalogue to CSV in Shopify's own product-import format: every public product and variant, up to the first 10,000, assembled in your browser. Detection is reported honestly. Weak app matches are marked unverified rather than dropped, unknown hosts are counted so gaps stay visible, and a customized, bespoke or headless build is labelled as such instead of being guessed at. Four permissions, no account, no sign-up, and your browsing history is not collected. The full source is MIT licensed and published, so every claim here is checkable against the code. Not affiliated with Shopify Inc.

    Tablesaw

    Tablesaw

    A group of plugins for responsive tables

    The Stack Table stacks the table headers to a two column layout with headers on the left when the viewport width is less than 40em (640px). If you only want to use the Stack Table and don’t want all the extra features (save yourself some bytes), Tablesaw provides a Stack-Only version. To opt-out of inline label creation (the table header cell text that shows at small breakpoints) on a per-table basis, use <table data-tablesaw-no-labels>; on a per-row basis, use <tr data-tablesaw-no-labels>; on a per-cell basis, use <td data-tablesaw-no-labels>. When the table cell is empty, use <table data-tablesaw-hide-empty> to hide the header when stacked. The Column Toggle Table allows the user to select which columns they want to be visible. The user always has the option to select all columns. If the table gets too wide for the viewport, it can overflow and cause a page-level scrollbar.
