Dillo is a lightweight, minimal graphical web browser, designed for speed, low resource usage, and privacy. It is written in C and C++ using the FLTK (Fast Light Toolkit) GUI library. Its goals include enabling web access on old or constrained hardware, using slow or unreliable network connections, minimizing dependencies, and avoiding many of the complexities and overheads of modern full-featured browsers. It omits many modern features (notably JavaScript), instead focusing on rendering HTML (mostly older/standardized subsets), images, and some CSS, while keeping the codebase small. It is free/open source under GPL-3.0.

Features

  • Very small binary size and low memory footprint, aiming to run even on ancient hardware or embedded systems
  • Support for standard protocols: HTTP, HTTPS, FTP, and local files; plugins extend support to protocols like Gopher, Gemini, IPFS etc.
  • Renders HTML 4.01 (and XHTML), CSS 2.1, some HTML5 / CSS3 components; but does not support JavaScript or complex scripting or active elements (Flash, Java)
  • Built-in “bug meter” to show validation problems (unclosed tags, etc.), helping ensure pages are standards-compliant or at least inform users/developers of errors
  • Customization via configuration files (appearance, default fonts, color, downloads folder, home page etc.), options for enabling/disabling image formats, zoom, scrollbar behavior etc.
  • Plugins support: Dillo supports external plugin modules/extensions (written in any language, interacting via standard I/O) for extra protocols or features

PRTG Catches Network Issues Before They Cause Downtime

Threshold-based alerts flag problems early, so your team can act before users notice, not after.

Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.
