SessionBox One pricing explained

We make Mosaic, the local-first anti-detect browser. We tried to be fair about the prices below; corrections to hello@mosaicbrowser.com.

SessionBox One prices by how many profiles you keep. Read on 2 November 2026, the plans were these.

SessionBox One's plans

Figures are USD, billed monthly, from SessionBox One's own pricing page on 2 November 2026. The free plan is no free plan. SessionBox One runs inside your own browser as an extension, not as its own anti-detect Chromium, so its fingerprint protection is not the same job.

The last row is Mosaic, for a reference point: one plan, $49 a month, any number of profiles. We put it there because the question behind "what does SessionBox One cost" is usually "what should I pay to run this many accounts", and the answer changes with the count.

How it works: Provider minting

What to watch on a SessionBox One bill

The plan price is rarely the whole bill. Proxies are the first thing it leaves out: every account wants its own exit, and residential proxy traffic often costs more a month than the browser does. The jump between SessionBox One's Hobby and Teams is where the per-profile math bites, so price the tier for the count you will reach in a few months, not the one you need today. The free plan (no free plan) is a fair way to try SessionBox One before any of that.

What the price buys

SessionBox One is good at running inside your existing browser as an extension, rather than a separate Chromium build. Those are real reasons to pay for it. What the per-profile price does not tell you is the rest of the bill: proxies, which every account needs, and seats if more than one person works in it.

How Mosaic prices the same work

Mosaic keeps profiles on your computer, so a profile costs us nothing to give away and Pro does not meter them. Pro is $49 a month, everything unlimited, and the first 14 days are free. Free holds 3 profiles and 10 profile creations, with the same engine as Pro. A provider saved from one gateway line mints its own session per profile, so one proxy plan serves a whole library without two accounts sharing an exit.

For the whole field at four sizes, see what a cheap anti-detect browser costs; for the plans that do not count profiles at all, the browsers with unlimited profiles. Mosaic Pro is $49 a month for any number of profiles, with the first 14 days free; Free holds 3 profiles and 10 profile creations.
