Mattrbld v1.5

Welcome to the first Mattrbld update of 2026! This one has been in the works for a while and features a couple new additions on top of the regular bug fixes and quality of life updates, so let’s dive right into the highlights.

Improved Invite-Links

Since release, it’s been possible to invite users to a Mattrbld project using an invite link. These links were originally intended to be used only once for the initial import, as the primary way to interact with projects is the projects overview screen.

However, based on user feedback, it became clear that many non-developer users did not discover the projects overview, since they only ever worked on one project. Instead, they kept using the invite link they were originally sent to access their project.

Mattrbld now accounts for this use-case by automatically redirecting to the project if an invite link for it is opened and the project is already imported. This also opens the option for developers to create a generic import link (one without a pre-set email and name parameter) and set it as a redirection target for say an /admin route on their project for an even more frictionless content editing experience.

A New Default Field: Icon

For the first time in a while, a new default field was added to Mattrbld. The brand-new icon field makes it possible to create custom icon pickers for your projects by specifying a folder for images and the way a picked image should be added into the content. This works best if the specified folder only contains SVGs or PNGs with transparency.

The field has multiple options, all of which are documented on the page linked above, but the most important ones are:

• sourceDir, which describes the path to the folder with the icon images. All eligible files in nested folders will also be shown at the top level.

• insertAs, which controls whether the image should be added to the content either as a full path to the selected file, or based on a custom URL template

• preserveColor, which disables the automatic masking used by Mattrbld to show the selected files in the UI. This option has no effect on the file added to your content and should probably be enabled if your image files have no transparency.

Other Changes

This update also comes with a slew of smaller fixes and quality of life improvements like clearer loading states for buttons during onboarding, consecutive collapsible container fields being displayed as an accordion, and more reliable field visibility settings and custom field versioning. As usual, you can get more details from the full changelog in the app.

Behind the scenes, I am still working at improving the quick start guide whenever I get the chance, as well as chipping away at the open issues one at a time.
