Dillo
What Dillo is
Dillo is a free, open-source graphical web browser for Linux, macOS, and Windows desktop computers. It is designed for resource-constrained machines and slow or unreliable networks, with efficiency, security, and privacy among its stated objectives. Dillo uses its own rendering engine, supporting a subset of HTML 4.01 and CSS 2.1 together with some HTML 5 and CSS 3 elements. JavaScript is not supported. The browser handles HTTP, HTTPS, FTP, and local files; plugins can add protocols such as Gemini, Gopher, and IPFS. Tabs, bookmarks, page history, text search, zoom, configurable keyboard shortcuts, and built-in ad blocking are included. Cookies are disabled by default, and settings can block automatic requests to other domains or stop automatic image loading. Dillo cannot play audio or video directly. Plugins can translate formats, implement protocols, or provide services through standard input and output. The listed latest release is version 3.3.0, released on 2026-04-26.
