Mattrbld v1.6.0 has been out for 12 days now, introducing the option to show raw file and folder names on a per-Collection basis. 🎉

As a positive side-effect, the algorithm making filenames more human-readable was improved to be more robust.

(Forgot to post this on release day, but thought you’d still like to know.)

Mattrbld v1.5 is out. 🥳

It’s the first update of 2026 and comes with a bunch of improvements and two new features. 👌

Learn more in the post below or the full changelog in the app.

2025 is coming to a close and with it the first year of Mattrbld being available as an open source project. During this year, there were four feature releases and this blog post outlines some of the highlights, which hopefully made Mattrbld more enjoyable to use!

Take care everyone and see you in 2026. 🥳

Mattrbld v1.4.1 is out! 🥳

This release includes some changes based on user feedback, such as renamed labels in file lists, which will hopefully make things easier to understand.

Other highlights include:

- Support for Avif images in the Media Library
- Automatic addition / removal of Collections in the sidebar
- An option to quickly copy the URL of linkable Collections from the file view

And much more, check out the in-app changelog after updating! 😊

PSA: there currently is some maintenance work going on on the backend, which is why the default CORS proxy server is currently not active and syncing will not work if you rely on that proxy.

Edit: everything should be back up and running as usual. Thank you for your patience!

Mattrbld v1.3.0 is out! 🥳

Highlights of this version are:

- Support for crisper project avatars
- File name presets for new items in Collections
- A new progress indicator while files are being downloaded from the remote

Along with the usual bug fixes and dependency updates. 😊 Enjoy!

A couple of days ago, version 1.2 was released, introducing a new visual change preview for updated images, a (long-awaited) rework of the field visibility system, among other things—and Mattrbld will now remember your preferred sorting order in Collections and other file lists. 🎉

See the changelog in your projects’ dashboards for the full changelog.

It’s already April, kind of hard to believe. 😳

In any case, here’s a very broad picture of what’s happening with Mattrbld: https://mattrbld.com/blog/2025/forward-momentum/

Worried about the situation in the US? Feeling like your website or content management system are too dependent on US companies and infrastructure? 😱

Maybe give Mattrbld a shot. 😉 It’s a free and open-source headless CMS made in Germany.
