[Baseline](https://web-platform-dx.github.io/web-features/)
gives you clear information about which web platform
features are safe to use in your projects today. When reading an article, or
choosing a library for your project, if the features used are all part of
Baseline, you can trust the level of browser compatibility. By aligning with
Baseline, there should be no surprises when testing your site.

## Baseline and Google Chrome

Baseline is a project originated by a team at Chrome.
Through our research we'd learned that many developers found changes to the web
platform confusing. In particular, you told us it was a challenge
understanding which features were supported in all browsers.

When talking to developers we realized that until fairly recently many of you
used Internet Explorer as a baseline for browser support. The site needed to
work in IE11, therefore you would only use features supported in IE11.
With Internet Explorer going away, and browsers on ever-faster release cycles
aligning to particular browser versions became much harder.

Therefore Baseline was designed to be a line showing when features could be
deemed ready to use, based on being available across all browsers. The line
wouldn't be tied to any particular browser version, but instead based on
interoperability.

> **Note:** For more about the ideas behind Baseline, [watch the launch video](https://web.dev/blog/introducing-baseline) from Google I/O 2023. The original launch of Baseline had a slightly different definition. Read about the reason behind the changes in [A definition update for Baseline](https://web.dev/blog/baseline-definition-update).

## A collaboration with other browsers and the community

For Baseline to become the way we talk about availability, we knew it couldn't
just be a Chrome project. It needed input and alignment from other browsers
and the community.
Therefore we quickly moved the project to the ownership of the
W3C WebDX Community Group. This group decided on the definition of Baseline,
and also hosts the work to define the web platform as a set of features.

Anyone is welcome to join the WebDX Community Group and
contribute to discussions about Baseline, the web features work, and other
issues relating to developer experience.

We're excited to continue to drive this project, in collaboration with the
community. On [web.dev](https://web.dev/baseline), expect to find information about how to use
Baseline in your workflow, and information about the features becoming part
of Baseline each month.
