DEV Community: Gimli

I built a TailwindCSS extension tool that got 10k+ users. I'm making it a commercial product to survive the tech market.

Gimli — Mon, 01 Jun 2026 19:17:50 +0000

The biggest change in this release is undoubtedly that Gimli Tailwind is no longer free (currently $49). On the pricing page, I gave the following reason for making this shift:

"Up until now, Gimli Tailwind has been completely free. It’s a tool I built because I needed it, and seeing over 10,000 installs has been incredible.

But the truth is, development has slowed down because I haven’t been able to justify the time away from paid work…"

To be completely honest, another big reason is the current tech job market. I’m currently employed as an IT consultant but am on parental leave until August, without a client to go back to. It’s a strange time to be away from work right now, especially when all you hear about from the tech world is AI and mass layoffs. I just don’t know what to expect when my leave ends.

Now, I don’t realistically believe I can make a full living selling Gimli Tailwind licenses. It is a pretty niche product, after all. But having some sort of side income would offer a safety net if things go sideways with my day job. Beyond that, it would simply be nice to be able to take some time away from “real work” to focus on a project I am genuinely passionate about.

I do understand the frustration of expecting a free tool and suddenly being met with a purchase screen. I actually just got my first review after going commercial:

"Superb extension, unfortunately now a paid one. (Translated from French)"

1/5 Stars.

It does feel a little unfair. Like solo developers aren’t allowed to make any kind of money, only big corporations! But hey, they did call it a “superb extension” so I can’t be that mad about it.

What’s New in 5.1?

Anyway, enough about that. You might be wondering: does this new paid version actually come with any new features?

Yes! Gimli Tailwind 5.1 now supports arbitrary values (like mt-[10px]) and custom fraction values (like w-7/13) directly via the UI.

This was actually quite a bit trickier to implement than I first anticipated. So the focus for this release was on getting everything to work “under the hood” rather than polishing the interface. For the upcoming 5.2 release, I plan to focus more on the UI/UX side, which I think still has plenty of room for improvement.

Watch this video to see the new arbitrary values in action

One More Thing…
A while back, I released Gimli Mouse Tracker.

It is a single-file, no-dependency Web Component that tracks the user’s mouse movements with tunable physics parameters, then outputs the results as CSS custom properties. I never actually made a proper post about it for whatever reason, so I thought I’d just mention it here instead.

Gimli Bootstrap: The smart DevTools extension for Bootstrap developers

Gimli — Wed, 03 Apr 2024 19:12:32 +0000

Hello! 👋

I've made a Chrome extension for Bootstrap developers which I hope you find useful.

Here is a short introduction video.

The extension is a fork of Gimli Tailwind. But it was it was modified for Bootstrap development.

It’s been a while since I last worked with Bootstrap on a project, and I would greatly appreciate feedback from anyone using Bootstrap. 😊

Gimli Tailwind now features a sleek dark UI theme!

Gimli — Wed, 20 Mar 2024 10:48:41 +0000

In Version 4.1 and 4.2, I’ve primarily focused on addressing bugs and optimizing code. However, I’ve also made some subtle yet valuable improvements!

Gimli Tailwind 4 is out - the most popular DevTools extension for Tailwind CSS developers

Gimli — Mon, 22 Jan 2024 07:08:03 +0000

It’s been almost a year since 3.0 was released. Today I’m happy to announce that Gimli Tailwind 4.0 is finally released.

If you are a Tailwind CSS user and haven’t used Gimli Tailwind yet, get it here. You may also want to look at this short introduction:

What’s new
Autocompletion — with CSS property name support!

I personally really like this feature. It’s nice to be able to use the keyboard and not be completely reliant on the UI.

Values within the same utility group will automatically be replaced. For example, if you have the classes: “grid m-10 pt-2”, then add “m-2” using the autocomplete input. The result will be: “grid m-2 pt-2”.

Another useful feature is that the autocomplete does not only work for utility classes. Let’s say you want to change the line-height. But you are new to Tailwind and do not know what those values are called. Then you can search for the CSS property name: “line-height”, and press enter, and now all line-height utilities are shown (leading-1,leading-2, and so on)

Quickly Copy all class names -button.

This was the first feature request I got. I just wasn’t sure where to put it in the UI until now.

New utilities

Tailwind 3.4 added many new utilities which are now also added in Gimli Tailwind. The size-* utilities are not shown in the UI but adding them using the new autocomplete feature works!

Updated UI

Devtools itself changed its colors a while back. Gimli Tailwind has been updated to use the same colors.

The 2xl variant has been added.

Bug fixes and other minor improvements.

As always, many minor bugs have been fixed and I’m sure some have been added too. If you find any bugs or have any other feedback. Please let me know.

DevTools Extension for Tailwind CSS

Gimli — Mon, 01 Aug 2022 10:11:29 +0000

Tailwind CSS is amazing but it's not always easy to remember all the different utilities. Therefor, I created Tailwind DX (the name will change due to legal reasons).

Here's a short video of it:

Tailwind DX let's developers debug and work with Tailwind CSS in a more intuitive way.

Here are some feature highlights:

Instant feedback
Building complex layouts takes a lot of trial and error. Tailwind DX lets the developer preview changes just by hovering on different values. We also let developers:

Ctrl+Click to toggle values on/off
Ctrl+Hold-and-drag to use inputs as sliders

By focusing on instant feedback, we enable developers to Build better websites faster.
