Browser tooling, taken seriously.

BrowserRoster is a product of OARN Services, an Ontario-based technology company building serious tooling for marketing, QA, and research teams.

Most multi-profile browsers in the market are JavaScript-layer wrappers that inject overrides into pages after they load. We took a different approach: a forked Chromium build with native C++ patches at the rendering engine. Canvas, audio, WebGL, fonts, navigator surfaces, and screen geometry are all consistent and isolated per profile before any page script executes. That gives our customers profile integrity that survives serious scrutiny, and it gives platforms confidence that legitimate use cases are handled cleanly.

We are deliberately narrow about what we will and will not support. The technology underlying multi-profile browsers can be misused; we have a written Acceptable Use Policy that excludes the misuses and an enforcement posture that takes it seriously.

If you're building something legitimate and want to see how BrowserRoster fits, the fastest path is getting in touch.
