Uisual is free and plain HTML/CSS landing page templates for startups. No JS. You can use them to launch your app, ebook, extension, etc. I'm planning to add more designs, a design a week. There will be pricing section, testimonial section, etc. But for now, only 3 templates.
Let me know what you think.
I just found your site and it is the perfect match for a sideproject of mine.
Your designs are super clean, easy to adapt and your CSS is a dream to look at. Great work! :)
