DiaTweaks brings various UI unofficial customizations to the Dia Browser that are natively unavailable

A new (unofficial) tool called DiaTweaks gives Dia users fine-grained control over the browser’s interface that the official app does not offer.

It was created by a developer (@JaceThings), who posted a thread on X about the tool. The thread also includes a video demo of DiaTweaks in action.

You might recognize the developer from our previous articles about Dia browser updates. Until The Browser Company resumed sharing detailed changelogs, unofficial Release Notes were regularly provided by JaceThings.

JaceThings first introduced DiaTweaks on October 30, 2026, with a short demonstration and a straightforward message: Users do not necessarily need another browser when their favourite one lacks a feature. Sometimes, patching it is enough. The announcement also linked the project’s early GitHub repository.

However, the idea subsequently attracted considerable interest, which prompted the developer to return on November 1 with a more cleaned-up installation experience.

So, the installation, setup, updates, uninstallation, and documentation are more straightforward. There was also some care put into small, quality-of-life details, such as previews that adapt to whichever tab-bar layout the user prefers. Some GitHub pages were also rewritten to make them easier to follow. Existing users of DiaTweak could simply update with a single terminal command.

As mentioned previously, the project is available through GitHub. Here’s how you can install it:

1. Place Dia in Applications. (Confirm that Dia is in the Applications folder; otherwise, this won’t work).
2. Install Apple’s developer tools if you don’t already have them. Paste the following into the terminal:
   Terminal

   xcode-select --install

3. Run a Git clone and installation script. Paste this into the terminal:
   Terminal

   git clone https://github.com/JaceThings/DiaTweaks.git ~/DiaTweaks && ~/DiaTweaks/install.sh

It might fail to show the option under Settings in some cases. If it happens, head over to the Terminal once again, and paste ~/DiaTweaks/install.sh into it.

You’ll get a prompt asking you to install Rust, and you also have to grant permissions for Dia Safe Storage. The Dia browser will automatically restart if you have it open, and you will be able to find the “Patches’ sub-menu under Dia Settings.

You get edge-to-edge webpages without default padding, square corners around webpage/sidebar boundaries, a completely hidden toolbar with optional hover-based reveal, the ability to hide individual Chat, sidebar, and recent-tabs buttons, and automatic tab grouping by domain.

Other additions include profile emojis instead of dots, translucent sidebars, compact sidebar headers, and window controls that preserve an active appearance even when unfocused. The feature list is rather long.

If you’re unhappy with any of the changes, or if the browser misbehaves, you get the option to restore the original Dia browser without any patches. That’s the final option in the sub-menu.

In other Dia news, the company accidentally revealed a revamped settings page and improvements to Air Traffic Control recently. More on that here.
