Which lightweight browser created by Jorge Arellano Cid uses the FLTK toolkit? Dillo. It is a minimalistic browser built for speed, low memory use, older computers, and embedded systems.
Chilean software engineer Jorge Arellano Cid conceived Dillo in late 1999 and released its first version in December of that year. His goal was to make the web accessible without requiring a new computer or broadband connection. Dillo was designed to run well even on an Intel 80486 processor using dial-up access.
The project originally used C and the GTK+ toolkit. Dillo 2, released in 2008, moved to the Fast Light Toolkit, better known as FLTK. That change reduced dependencies and cut the browser’s memory footprint by about 50 percent. Dillo 3 later continued using FLTK 1.3.
Its small footprint comes with trade-offs. Dillo supports HTML, XHTML, CSS, and images, but ignores scripting entirely, so many modern interactive sites do not work correctly. It is therefore not a stripped-down Chrome alternative; it is a deliberately limited browser for efficiency and simplicity.
