Opera is a multi-platform web browser developed by a company originally known as Opera Software. It provides browsing, privacy and performance tools and has been distributed on desktop and mobile devices. The project has offered integrated utilities in some releases, including an e-mail client, a webfeed reader and IRC support in earlier builds — features documented by the project's own pages and changelogs (e-mail, webfeeds/IRC).

Key characteristics

Opera is designed to be compact and feature-rich. Over time it has included:

  • Built-in features: pop-up blocking, integrated search, Speed Dial (custom start tiles), ad blocking, and a free VPN in some editions.
  • Performance tools: a battery saver mode, data compression on mobile editions, and network optimizations.
  • Customization: themes, extensions, and configurable keyboard/mouse gestures.

Platforms and editions

Opera has been produced for many operating systems. Desktop variants have supported multiple platforms including Microsoft Windows, macOS, Solaris, FreeBSD and Linux. Mobile-focused editions include the long-running Opera Mini and Opera Mobile for feature phones and smartphones (mobile, PDAs), while custom builds have appeared on game consoles and interactive television platforms (gaming/TV).

History and engine development

Originating as a research project in the 1990s, the browser matured into a commercial product and became known for introducing several interface and usability ideas now common in other browsers. Historically Opera used its own layout engine, Presto, and later adopted widely used rendering engines to improve compatibility. The company behind the browser is associated with Norway — its early operations were in Oslo (Oslo, Norway).

Variants, use cases and notable facts

Different editions address distinct needs: Opera Mini emphasizes bandwidth savings by compressing pages on a server, Opera GX targets gamers with themed controls, and desktop Opera focuses on integrated workflows. Opera has been recognized for pioneering features such as tabbed browsing, Speed Dial and early integrated blocking tools. Users choose Opera for its combination of built-in utilities and experimental features, though its market share is smaller than the largest browser vendors.
