About a0a

A collection of small, trustworthy web utilities.

a0a.uk is an independent project. Every tool on this site runs entirely in your browser. The site is static HTML — there is no backend to send your input to, and there is no analytics script watching what you do.

The goal is a set of utilities you'd trust to paste a production secret into. That means:

• No third-party scripts, no CDNs for JS or CSS.
• Strict content-security-policy that blocks external network calls.
• Tools each live on their own page; view-source is readable.
