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.
skip setup entirely. just a tab system, address bar, and security settings. you decide what comes next.
a familiar browser experience. history, bookmarks, appearance settings, and a search engine of your choice.
everything in Standard, plus tools for building and debugging. devtools, source viewer, and advanced settings.
browse the addon store during setup and hand-pick exactly what gets installed. total control from the start.
