Cosmic Themes provides some of the best Astro themes out there. They are well designed, easy to customize and, most importantly, the team is very responsive concerning support and feature requests. Using their themes allows you to forget about the design and focus on content creation.



Creator of My Lift Log

My step-dad is starting a construction business and we're looking through Astro themes right now for his website and stumbled upon Cosmic Themes "Galaxy" theme. Absolutely filthy. Excellent work, man.



Freelance Web Developer

The Blogsmith Pro theme is ridiculously well put together and documented. I learned a ton about Astro engineering by studying it, and I've already used some of the components for my web design clients. Plus, it shaved hours off my dev time so I could focus on writing SEO articles instead of coding something from scratch.

It's the cleanest template standup experience ever! I've never used Astro, but looking at the demo, code, it should be fairly simple pickup on top of my existing React and NextJS experience.

I'm not a front-end dev, but I wanted to rebuild my personal site with Astro. If you're in the same shoes, I can't recommend enough Cosmic Themes. The entire process required exactly one CSS change.
