A browser that keeps your business to itself.
Sreon is a small, privacy-first desktop browser. Real workspaces, a command menu, an app lock, and encrypted local storage — built to be fast, quiet, and yours. Free and open source.
Why I built this
I kept counting how many things a "normal" browser does before I've typed anything: sync accounts, telemetry pings, extension marketplaces phoning home, a new-tab page quietly profiling what I look at. None of it was there because I asked for it.
I wanted a browser that didn't need a privacy policy longer than its changelog.
Sreon started as a weekend project to see how small a real, daily-usable browser could get if it only did what I actually use: tabs, workspaces to keep Personal and Work apart, a command menu instead of hunting through settings, and storage that's encrypted by default instead of as an afterthought.
It's open source on purpose — not as a slogan, but so the privacy claims on this page are things you can go verify in the source rather than things you have to take my word for.
Everything you'd want from a browser. Nothing you didn't ask for.
Real tabs, real workspaces
Keep Personal and Work fully separate — each with its own logins, bookmarks, and history, isolated from the other.
Command menu (⌘K)
Jump to a site, switch workspace, or change a setting without leaving the keyboard.
App lock
Gate the whole app behind an optional password, salted and hashed locally. Sreon never stores it in the clear.
Ad & tracker blocking
A local domain list blocks known ad/analytics/tracker requests before they load — no network call needed to check it.
Encrypted local storage
History, saved logins, and bookmarks are AES-256-GCM encrypted on disk, with per-workspace keys derived by PBKDF2.
Make it yours
Accent colors, glass blur and opacity, corner radius, and your own photo or video as the background.
Try the interface
This is a live, interactive preview of Sreon's UI running right here in your browser — click around. Try typing in the address bar: it searches a small local index instantly, with the timing shown, because nothing here calls a server. It's a front-end demo, not the full app: download Sreon below for real browsing, encryption, and the ad blocker.

How privacy actually works here
Not a policy — a mechanism. This is the actual order of operations every time you use Sreon.
-
01
You browse normally
Pages render like they would in any browser. There's no separate collection layer sitting in front of your traffic, and no analytics SDK compiled into the app.
-
02
What you save gets encrypted immediately
History, saved logins, and bookmarks are encrypted with AES-256-GCM on your device before they ever touch disk — not batched, not deferred.
-
03
Each workspace gets its own key
Keys are derived per workspace with PBKDF2, so Personal and Work can't read each other's data even while both are unlocked.
-
04
Nothing is sent anywhere
No account, no server-side sync, no crash reporter phoning home. There's nothing to breach on our end because there's no "our end" holding your data — and the source is open, so that's checkable, not just claimed.
