Contoweb ensures a proper crunch on the topic of data protection.

When cookies disappear, the web needs new recipes. The new solution is called CHIPS. We brought it to Symfony and Laravel so that web applications can continue to run securely. Open source for everyone.

Not cookies, CHIPS ist what the web needs

The web is changing. We are responding to it.

Starting in 2024, major browsers decided to block third-party cookies. An important statement for data protection, as they are the door opener for tracking across the entire web. But on the other hand, this becomes an issue for tools that need to run across multiple domains. Without a replacement, simple website integrations would be impossible. With CHIPS (Cookies Having Independent Partitioned State), each website gets its own cookie drawer. How does it work? Very simply: cleanly separated and compliant with data protection regulations.

It used to be like this ...

A cookie was stored for an address, for example analytics-tool.com. If website A has integrated the tool, the cookie was set. If website B integrates the same tool, it accesses the same cookie. The problem: The tool could thus track users unnoticed across different websites. Quite brazen and not at all compliant with data protection regulations.

With CHIPS, there is no more snacking on other people's food

Newly, each cookie will be bound to the website, for example with website-a.com and analytics-tool.com. This means that Website A and Website B each get their own separate cookie. The integrated tool works on both sides, but no more data can be linked. The function remains, but the tracking disappears.

Code made in Wittenbach, used worldwide

CHIPS was initiated by Google. But for the technology to reach millions of PHP applications, it needs clean integration at the framework level. Contoweb developed CHIPS support in Symfony and Laravel – two of the most widely used PHP frameworks in the world. Today, our code is part of the official releases. With our open-source contributions, we make the Internet safer.

The crunch behind it

Time pressure, coordination and precision: The countdown began in 2023, as browser manufacturers had a clear timetable for the end of cookies by 2024. Our CHIPS implementation therefore had to be quickly integrated into both frameworks. First into Symfony, then into Laravel. And this without any breaking changes, so that the millions of existing applications remain stable.
