Iridium Browser is based on the Chromium code base. All modifications enhance the privacy of the user and make sure that the latest and best secure technologies are used. Automatic transmission of partial queries, keywords and metrics to central services is prevented and only occurs with the approval of the user. In addition, all our builds are reproducible and modifications are auditable, setting the project ahead of other secure browser providers.

Iridium Browser - Transparency


With Iridium, the whole process is entirely transparent. The public Git repository allows a direct view on all changes made. The complete source code is therefore available.

Iridium Browser - Privacy


Iridium Browser has various enhancements where it forces strict security to provide the maximum level of security without compromising compatibility.

Iridium Browser - Deployability


We try to distribute it in ways where it allows easy installation and yet allows administrators to deploy it easily. An example is an MSI-based installation mechanism for easy deployments throughout an entire organization.

Iridium Browser - Motivation


There are many browsers out there. Chrome is fast, stable and user-friendly but does not meet many organizations’ demands for privacy. Since the tight integration with its inventor (Google) makes many things easier, it does not comply to restrictive data environments. Iridium is not another new browser from scratch. It takes the Chromium code base and enhances its security and sets certain policies by default. There are many forks of Chromium-based browsers, yet, in our opinion they failed in many other key areas important for adoption.
