Functionality

Features

Plug and play

Simply drop in Klay.php, include it, put in a few lines of config and you're good to go, whether you're developing a new site or fitting it into an existing. It's that easy.

PHP based

Will run on anything from a shared hosting webhotel to a DigitalOcean droplet or a FortRabbit app.

Flexible

Total freedom over everything from item types to fields and blocks. Build whatever you want. Use Klay to render your site with routing, controllers, views and asset render functions, or use Klay as your selfhosted headless API CMS for an app or website.

Super fast

Edit content faster than ever. Lightning fast admin panel with keyboard shortcuts.

Tiny footprint

Entire CMS lives in a single 350kb file. That's 0,04% the size of WordPress. No reason to clutter server ressources with jank.

Featured packed

Packed with everything from seeding to webhooks and live previews.

Multi-language

Multilingual built into the core. No more 3rd party plugins doing things halfway.

URL routing

Built-in. Make an API? Filter certain HTTP methods? You've got it.

Content seeding

Want to test how fast your site will behave with 10.000 news articles? With the built-in seeder you can quickly generate dummy items.

Safety first

Never lose content again. Create zipped content backups directly from the admin panel.

Snappy database

Fast and scalable SQLite database. File-based and portable with no need for separate database server. Built-in query engine.

Optimized assets

Uploaded images are automatically scaled to preferred size versions.

Testimonials

What people are saying

Headless API was too expensive for us, and Craft was okay, but forced us to do things we didn't want to do. Klay is so small, but packs a powerful punch.

Mikkel Grønvold

Backend developer

Once I saw this and tried it out I was hooked. No more WordPress. Klay can even quickly be retrofitted onto existing sites with no CMS.

Laurits Faber

Frontend developer

Klay is so much faster than other CMS systems. Both in development time and in the admin panel. It's got every functionality needed and is a joy to work with. Give it a chance!
