About
Opera Developer is the early access version of the Opera browser, where Opera tests new features, tools, and experiments before they reach the main release. It is recommended for developers and advanced users. Before features become part of the Opera browser, they go through several rounds of testing, and once they are ready, they are shared publicly so users can test them and provide feedback that shapes them.
Because these features are still in development, things can occasionally be unstable or crash, so the website advises testing with caution. Not every experiment will make it to the stable release. Users who want a reliable, everyday browsing experience are directed to the stable version of Opera instead.
Opera Developer is available as an offline package in 64-bit, 32-bit, and ARM versions. The website states that the download is safe and says users can follow the Desktop team's blog to stay up to date on what's new.
