Osmium is a Chromium-based browser stripped to it's core. no bloat, no tracking, no decisions made for you. build your browsing experience with addons, exactly how you want it.
out of the box, Osmium gives you a tab system, an address bar, and security controls. every other feature is your choice.
a simple, fast tab system with no visual noise. tabs do what tabs should do, and nothing more.
navigate to URLs directly. install a search engine addon to unlock search directly from the bar.
granular per-site and global security settings built in from day one, no addons required. Osmium itself never tracks your activity.
extend Osmium's functionality with our custom addons. every addon is placed through a thorough review process to ensure it's honest about its capabilities, permissions, and security practices, and hosts no malicious content.
a minimal built-in downloads panel with strong security. easily see progress, block, and manage your downloads without any distractions.
no sign-in, no sync, no telemetry by default. Osmium is yours and only yours from the moment you open it.
Pick an addon below and see how it changes Osmium — install only what you actually want.
on first launch, Osmium walks you through setup where you can either choose a preset or select each addon individually — you can even just skip it entirely. every choice is reversible.
a minimal setup with just the essentials. perfect for users who want a lightweight browsing experience.
a familiar browser experience. similar to other modern browsers, it's easy for new users to get started. nothing more, nothing less.
everything in Standard, with more variety and customization. endless utilities from tab windows to screen casting give you everything you could ever need.
everything in Plus, along with tools for building and debugging. perfect for web developers and power users.
