About this site

toolkit is a collection of 39 free, browser-based utilities for SOC analysts, sysadmins, and developers: encoders, hash tools, network lookups, log helpers, and the small conversions you need ten times a day.

It exists because most tool sites bury a textarea under three ad units and a newsletter modal. These pages load fast, work offline where possible, and never ask you to sign up.

Privacy

Almost every tool runs entirely in your browser; your input never leaves the page. The handful of tools that need a server (DNS lookup, Whois, HTTP headers, CVE lookup, SPF/DKIM/DMARC, My IP) proxy only the query you type through a Cloudflare Worker, and nothing is stored. Tools that call a server are marked with an SSR badge on the homepage.

Who built it

Built and maintained by Luke Albertson, a security engineer. Bug reports and tool ideas are welcome; find contact info on the main site.
