What's new in DevKits

Every release, in the open. New tools, improvements, and fixes — with links to the exact pages we shipped. If you spot something missing or broken, tell us on the message board.

  1. Latest

    Unified page hero and consistent widths across the site

    Every non-tool page (Changelog, Community, Comparisons, About, Category hubs, cheatsheets, references) now shares the same signature gradient hero and a consistent max-width, matching the home page and the tool pages.

    Design consistency

    • Improved
      Introduced a shared PageHero component with the brand radial-gradient — same look as the home hero across Changelog, Community Board, /compare, /visualize, category hubs, cheatsheets, references, About/Privacy/Terms/Contact.
    • Improved
      Aligned page container width to max-w-6xl on every page — the horizontal edges now line up cleanly with the header and footer instead of jumping between 3xl / 4xl / 5xl / 6xl.
    • Improved
      Long-form pages (About / Privacy / Terms / Contact) keep a comfortable 3xl reading column inside the wider frame, so line lengths stay readable.

  2. Image Toolkit — 19 privacy-first image tools

    A complete image utility suite, from EXIF forensics to format conversion, resizing, cropping, favicon generation, SVG optimization, and color extraction. Every operation runs locally.

Our commitment

We ship in the open. Every user-visible change goes into this changelog — new tools, behavior tweaks, security posture, and bug fixes. We don't quietly harvest data, we don't add trackers behind your back, and we don't upload your files. If a release ever changes any of that, it will be right here at the top.
