To this point, Opera was
trialware and had to be purchased after the trial period. With version 5.0, released in 2000, Opera became
ad-sponsored, displaying ads to users who had not paid for it. Subsequent versions have given users the choice of seeing

In 2016, a free virtual private network (VPN) service was implemented in the browser. Opera said that this would allow encrypted access to websites otherwise blocked, and provide security on public WiFi networks. It was later determined that the browser VPN operated as a

domain name system (DNS) which is not part of the traditional DNS directly without the need of a plugin or add-on. This was through a collaboration with a
San Francisco based startup, Unstoppable Domains.
In January 2022, Opera introduced Opera Crypto Browser into public beta, combining a non-custodial wallet with a dedicated browser for blockchain enabled services and Web3 technologies. On April 14 2022, Opera launched its Crypto Browser available on iOS devices.

E3 2019. The macOS version was released in December of the same year.
Opera GX adds features geared towards gamers on top of the regular Opera browser. The browser allows users to limit network, CPU, and memory usage to preserve system resources, with GX Cleaner, a tool that allows users to clear cache, cookies, and other junk.

Development stages
Opera Software uses a release cycle consisting of three "streams," corresponding to phases of development, that can be downloaded and installed independently of each other: "developer," "beta," and "stable." New features are first introduced in the
developer build, then, depending on user feedback, may progress to the
beta version and eventually be
released.
The developer stream allows early testing of new features, mainly targeting developers, extension creators, and early adopters. Opera developer is not intended for everyday browsing as it is unstable and is prone to failure or crashing, but it enables advanced users to try out new features that are still under development, without affecting their normal installation of the browser. New versions of the browser are released frequently, generally a few times a week.
The beta stream, formerly known as "Opera Next," is a

package, allowing stability and quality to mature before the final release. A new version is released every couple of weeks.
Both streams can be installed alongside the official release without interference. Each has a different icon to help the user distinguish between the variants.

Opera is one of the top 5 browsers used around the world.
As of April 2021, Opera's offerings had over 320 million active users.
Reception
The Opera browser has been listed as a "tried and tested direct alternative to Chrome."
It scores close to Chrome on the HTML5test, which scores browsers’ compatibility with different web standards.
Versions with the Presto layout engine have been positively reviewed, although they have been criticized for website compatibility issues. Because of this issue, Opera 8.01 and higher had included workarounds to help certain popular but problematic web sites display properly.
Versions with the Blink layout engine have been criticized by some users for missing features such as
UI customization, and for abandoning Opera Software's own Presto layout engine. Despite that, versions with the Blink layout engine have been noted for being fast and stable, for handling the latest web standards and for having a better website compatibility and a modern-style user interface.
