Contoweb packs a punch when it comes to data protection.

As cookies disappear, the web needs new recipes. The new solution? CHIPS. We’ve implemented them in Symfony and Laravel, to ensure that web applications can continue to run securely. They are open source for everyone.

The web needs CHIPS, not cookies

The web is changing. We are responding.

In 2024, major browsers began blocking third-party cookies. This was an important step for data protection, as cookies open the door to web tracking. However, doing so also creates issues for tools that need to operate across multiple domains. Without a replacement, simple website integrations are impossible. With CHIPS (Cookies Having Independent Partitioned State), each website gets its own dedicated cookie drawer. How does it work? Very simply: through separation and compliance with data protection regulations.

The way it used to be...

Previously, a cookie was stored for a specific address—for example, analytics-tool.com. If Website A embedded a tool, a cookie was set. If Website B embedded the same tool, it accessed the same cookie. The problem: The tool could be used to track users, unnoticed, across different websites. This was quite brazen, and not at all compliant with data protection regulations.

No more snacking from others with CHIPS

Now, every cookie is bound to a specific website. This means that Website A and Website B each get their own separate cookie. Integrated tools work on both sides, but data can no longer be linked between them. The functionality remains, but the potential for tracking disappears.

Code made in Wittenbach, used worldwide

CHIPS was initiated by Google, but reaching millions of PHP applications requires clean integration at the framework level. That’s why Contoweb developed CHIPS support for Symfony and Laravel—two of the most widely used PHP frameworks in the world. Today, our code ships in the official releases. Through our open-source contributions, we are making the internet more secure.

The time crunch

Time pressure, coordination, and precision: The countdown began in 2023, as browser vendors had a clear timeline to phase out cookies in 2024. Consequently, our CHIPS implementation had to be rapidly integrated into both frameworks. First in Symfony, then in Laravel—without any breaking changes, so that the millions of existing applications would remain stable.
