ShailStack makes the web faster to build and easier to use: a lightweight CSS library, free private online tools, and websites built for real businesses.
ShailStack is a lightweight CSS utility library with ready-made popup modals, plus a growing set of 21 free online tools — an AI visibility checker, an exam photo and signature resizer, PDF tools, image tools and everyday developer and text utilities. We also design and build websites for businesses.
Developers who want a small, fast CSS library they can drop into any project; students and job seekers who need photos, signatures and PDFs in the exact size an online form accepts; and businesses that want a fast website that shows up in Google and AI assistants.
The tools introduce people to ShailStack, and we earn from web design work. Everything on the site is free right now — any paid extras we add later will be optional, and the everyday tools will stay free, with no sign-up and no limits on normal use.
Yes. Image, photo and PDF tools run entirely inside your browser — your files are never uploaded to our server. The only tool that contacts our server is the AI Visibility Checker, which fetches the public web page you ask it to check. See our privacy policy for details.
