Opera for developers
Whether it’s promoting open standards, showing off some of our most novel pet projects with shiny demos or even inventing new tools, Opera has always been a tech company by, for and about people who are passionate when it comes to the web.
Updated a few times per week, Opera Developer gives you a sneak peek of upcoming features and experiments that might make their way into future products.
