## The proxy bill is usually bigger than the browser bill

Past a couple of dozen profiles, the exits cost more each month than the anti-detect browser. That is why we price per month, not per profile.

![One bill grows with every profile. Ours doesn't](https://mosaicbrowser.com/covers/proxy-bill-bigger-than-browser.webp)

Once you run more than a couple of dozen profiles, the proxies cost more each month than the anti-detect browser does. The browser is one subscription. The exits are one line on an invoice per profile, and that line grows every time you add an account. So when you price a setup, the question that decides the total is which proxies you buy, not which browser.

We sell the browser half, so we have a stake in saying this, and we will show the sum rather than ask you to trust it.

## Anti-detect browser cost and proxy cost grow differently

Every profile that keeps its own account needs its own exit. Two accounts behind one address look like one household to the site, and keeping that from happening is the whole reason to run separate profiles ([forty profiles, forty exits](https://mosaicbrowser.com/blog/forty-profiles-forty-exits) is the long version). So the proxy bill is per profile by nature, whichever way your seller meters it:

- On a per-IP plan you rent one address per profile per month, used or idle.
- On a per-GB residential plan each profile costs what it downloads, and a hundred profiles download about a hundred times as much as one.
- On a per-port mobile plan you pay for a port per profile that needs its own exit.

Mosaic Pro is $49 a month, one plan, with no per-profile pricing. The software line stays flat while the proxy line climbs. At a hundred profiles Pro works out at 49 cents per profile, and at a thousand it is 4.9 cents.

## Where the proxy line crosses the browser line

We use the round figures from [what a proxy costs per profile per month](https://mosaicbrowser.com/blog/proxy-cost-per-account): $3 an address a month on a per-IP plan, and $4 a GB on a per-GB one, with a light profile moving about half a gigabyte a month. Those prices are made up so the division is easy to follow. They are nobody's real price list.

| Profiles | Exits at $3 an IP | Exits at $4 a GB, 0.5 GB each | Mosaic Pro |
| --- | --- | --- | --- |
| 5 | $15 | $10 | $49 |
| 16 | $48 | $32 | $49 |
| 25 | $75 | $50 | $49 |
| 100 | $300 | $200 | $49 |
| 500 | $1,500 | $1,000 | $49 |

With these figures, per-IP exits overtake the browser at about 16 profiles, because $49 divided by $3 is 16.3. Light per-GB profiles overtake it at about 25. Heavier traffic gets there sooner: a profile on an image feed with video moves several gigabytes a month, not half of one. To find your own line, divide $49 by what one exit costs you a month.

Below that line the browser is the bigger bill. Past it, every new account adds to the proxy invoice and nothing to ours.

## Why we will not price per profile

A browser priced per profile puts a second per-profile bill on top of the one you already have. The cost of adding an account then doubles: one more exit and one more seat. That would make sense if each profile cost us something to run. It does not. Profiles, projects and API calls run on your own computer, and Mosaic has no cloud copy of them, so giving away the thousandth costs us nothing more than the first. ([One price](https://mosaicbrowser.com/blog/one-price) has the rest of that reasoning.)

Mosaic also sells no proxy traffic, so we gain nothing from the proxy line either way. There is no bundle of gigabytes for us to push you towards.

## Spend the time on the proxies

When the exits are most of the bill, they deserve most of the decision too. Four questions move the total more than the choice of browser does:

1. Per IP or per GB. A profile that signs in and reads is cheap per GB. A busy one is cheap per IP. The break-even is the IP's monthly price divided by the price of a gigabyte.
2. One session per profile. With a provider saved from one gateway line, every profile mints its own session id, so two profiles never land on the same exit by accident ([how providers mint sessions](https://mosaicbrowser.com/features/proxy-providers)).
3. Dead sessions. A residential session that reaches nothing tends to stay dead on the same token. Mosaic mints a different session instead of retrying the old one, so a bad exit costs one rotation and not an afternoon.
4. The checks. A Mosaic profile does not open behind a proxy that has not answered and tunnelled, and an exit can be scored for reputation before you trust an account to it. An exit you are paying for and cannot use is the most expensive line on the invoice.

Sharing one exit across many profiles is the obvious way to cut the bill, and it is the one saving we would not take. It turns several accounts into one household, which is exactly what you were paying the rest of the bill to avoid.

The prices for both plans, including the free one, are on [the pricing page](https://mosaicbrowser.com/pricing).

## Questions

### How much do proxies add to the cost of an anti-detect browser?

One exit per profile, every month. Multiply your seller's monthly price for one exit by the number of profiles. With our made-up round figure of $3 an address, a hundred profiles is $300 a month in exits before any software.

### At how many profiles do proxies cost more than the browser?

Divide the browser's monthly price by what one exit costs you a month. With Mosaic Pro at $49 and an exit at a made-up $3, the line is about 16 profiles. Put your own seller's price in and it moves.

### Can several profiles share one proxy to cut the bill?

They can, and then a site sees several accounts leaving from one address, which looks like one household. That link is the thing separate profiles exist to prevent, so budget one exit per profile.

### Does Mosaic sell proxies or include traffic?

No. Mosaic sells no proxy traffic. You bring a seller, save one gateway line as a provider, and each profile mints its own session from it.
