A software site has one job: show the product and earn the signup. Hassium’s front page opens on a clear promise with the product right under the buttons, then answers a buyer’s questions in the order they come up: what it does, who uses it and what it costs.
Swap in your own screenshots, plan names and prices, and the pages are ready for launch day.
Start with Cobalt, or pick another design under Styles in the Site Editor. Each one changes the brand color and the ground, and your content stays where you put it.
The three heading presets work with any design. Serif headings sets every heading in Hedvig Letters Serif, Sans headings uses Inter, and Serif display keeps the serif for the two largest sizes. Both fonts ship with the theme.
Most software sites need the same handful of pages, and building them one section at a time eats the week before launch. Hassium includes seven full page layouts. Insert one into an empty page and change the words.
Hassium builds every pattern from WordPress core blocks, so your content stays editable if you change themes later. Only the styling follows the new theme.
You can change the header, the footer and every template in the Site Editor, and build new pages from the included patterns without a page builder.
Hassium bundles Inter and Hedvig Letters Serif, so both fonts load from your own domain.
Hassium’s stylesheets add up to about 46 KB, and block styles load only on pages that use those blocks. The theme ships no JavaScript of its own.
The gallery below shows all 59 patterns in the inserter. Select any preview to open the full-size image, or follow a group’s demo link to see the patterns in place.
Shown in the Cobalt design with example content. Company names, quotes, prices and numbers are placeholders, and the product screenshots ship with the theme, ready to swap for yours. Full pages are shown from the top.

Hassium 0.1.0 is a first release, so it is wise to try it on a staging site with your own content and plugins before you switch a live site.
The pricing tables are layouts, not a checkout. Point each button at your signup or billing page, and add a form plugin if you want a working contact form.
Everything here is quick to set up, light on your pages and built to do one real job well. I only charge for the tools that can make you money. The rest are free.
I design, build and support every product on this site myself. When you email me, the person reading it is the one who wrote the code.
I’d rather ship one tool you’d miss if it vanished than ten that sit in your plugin list doing nothing.

Switch a feature off and it loads nothing. What does load stays small. A tool that replaces a plugin shouldn’t make your pages slower.
Clear screens, sensible defaults and settings written in plain English. If you need a tutorial for the basics, that’s my design mistake, not yours.
Full keyboard support, visible focus, proper labels and text you can actually read. When more people can use your store, more people can buy from it.
My paid tools help you sell, renew, license or convert. If one just sits in your stack, I haven’t done my job.
I won’t charge for anything that can’t make you money. The free tools get the same care as the paid ones, down to the last setting.
The complete Hassium SaaS theme is free under GPL-2.0-or-later. Download it, make it yours and use it on as many sites as you need.
