Details
The author built FastTool, a collection of 548 free browser-based tools, after getting frustrated with the poor experiences of using online tools that required sign-ups, ads, or data uploads. The project grew organically, with new tools added whenever the author encountered a task that lacked a satisfactory online solution. The architecture is designed to be extremely simple, with a single JavaScript file containing renderer functions for each tool, mapped by a slug. The entire site is static HTML and JavaScript, hosted on Cloudflare Pages at no cost. Privacy was a key focus, with all tools running client-side without any data leaving the user's browser. The site also supports 21 languages, including RTL layouts, using a single translation function.
