web.dev moves away from GitHub-hosted CMS
Paul Kinlan has announced that the infrastructure powering web.dev is changing. The site is moving from a custom, GitHub-hosted CMS to shared internal Google infrastructure, a shift that will alter how the community contributes content and fixes.
The original setup combined Lighthouse with 11ty to support a tool-focused vision of the site. As web.dev evolved into a content-only resource—with the /measure page relocated to pagespeed.web.dev—maintaining that bespoke stack became less of a priority. The goal now is to free up team resources for content and tooling while letting the maintenance burden be absorbed by existing internal systems. A secondary benefit is access to Google's localization pipeline, which should improve support for non-English-speaking developers.
Contribution model changes
The most immediate impact is on open contributions. Previously, fixes and new content could be proposed directly through pull requests on GitHub. That is no longer the case. Going forward, contributions must be submitted via the open issue tracker. The team still welcomes contributions, though Kinlan acknowledges the new process is "significantly more complex" for simple changes. In practice, the majority of content on the site has been created in-house or commissioned from known experts, such as the web.dev/learn courses.
Archive and licensing The prior infrastructure and its content history remain available in the repository on GitHub for those curious about the site's technical past. All material on the site, both existing and new, continues to be released under the Creative Commons Attribution 4.0 license, allowing anyone to reuse and adapt the content with proper attribution.
Kinlan calls the migration a shift so the team can "put more effort into making this site one of the best web development resources available." The transition will happen over the coming weeks, with any kinks expected to be ironed out in that period. He closed by thanking the long list of community contributors who have supported the site over the years.
