Top Web Browsers Collaborate to Improve Interoperability


The major technology companies that develop the best web browsers (Google, Microsoft, Apple, Mozilla, Bocoup and Igalia) and other supporters have announced that they have – for the very first time – have come together to improve interoperability and thus make things much easier for web developers. It’s all part of a new benchmark called Interop 2022, which aims to “improve the web development experience in 15 key areas“.

This project started in 2019 when these companies started this effort in order to understand developer frustrations with cross-browser compatibility issues and establish how improvements and new technologies could be implemented in the same way. The result was this new benchmark that establishes a common dashboard that will track progress in key areas that have been agreed upon with developer input. These key areas include cascading layers, CSS color functions, window units and browser scrolling, among others. They will also focus on the four main browsers involved, namely Chrome, Edge, Safari and Firefox.


The idea is that for each of these areas, each browser is graded throughout the year against a set of tests, and receives a score on how well they have implemented it. This will give them a chance to collaborate on how best to implement them in a way that benefits everyone.

Essentially, the goal is to make the web platform more usable and reliable for developers, so they can spend more time building great web experiences instead of working around browser inconsistencies.

Through last year’s Compat 2021 effort, it became clear that there is still room for improvement, so it is very encouraging that these major players can come together and work on a solution. Hopefully this effort will reduce frustrations with the web developer community and also result in a better experience for us users.
