Why ShareURL?
Frequently Asked Questions
Direct answers — no fluff
How do I host HTML CSS JS online for free?
Open the Host Project page on ShareURL. Write or paste your HTML, CSS, and JavaScript into the editor, name your project, and click Host Project. Your live URL is ready in seconds — no account needed.
Does it support JavaScript and CSS animations?
Yes, full JavaScript and CSS including animations, transitions, canvas, Web APIs, and event listeners all work. The project runs in a sandboxed iframe.
Can I host a portfolio or landing page?
Absolutely. Many developers use ShareURL to host portfolios, landing page prototypes, UI experiments, and demo pages. Permanent links keep your work accessible long-term.
Can I update my hosted project?
Currently, each Host Project action creates a new URL. To update, host the project again with revised code — you'll get a new URL to share.
What is a sandboxed iframe?
Your HTML project runs inside a sandboxed iframe, which means it can't access the parent page's cookies or make requests outside its own scope. This keeps visitors safe while allowing full JS/CSS functionality.
