Shifter in Mosaic: paste the gateway, mint a session

We make Mosaic, the local-first anti-detect browser; Shifter is a proxy seller you bring your own account to. This page is the setup, not a review of Shifter's network.

You bring a Shifter account; Mosaic brings the browser. Mosaic reads Shifter's gateway line from the seller's own documentation, so the line you copy from Shifter is kept as a template, and the targeting and session tokens are read from it rather than guessed.

Connect Shifter to Mosaic

1. In Shifter's dashboard, copy the gateway line for the pool you want, with your username and password in it.
2. In Mosaic, open a profile's proxy field, or the Proxies screen, and paste the line. Mosaic detects it as Shifter and saves it as a provider you can reuse.
3. Attach the Shifter line to each profile. Mosaic checks the exit it reaches before the browser opens.
4. Press Start. Mosaic checks the proxy before every launch and will not open the browser until Shifter has answered and tunnelled, so a dead proxy never leaks your own address.

Shifter's line has no session token Mosaic reads, so profiles share its rotation unless you paste one of Shifter's own sticky endpoints. If a Shifter endpoint stops answering, the launch stops and names what failed, so you fix the line rather than browse on your own IP.

How it works: Provider minting

What Shifter carries in its line

Shifter's gateway line, as Mosaic reads it, has no country, city or session token that Mosaic recognises. So Mosaic uses the line as you paste it: whichever Shifter endpoint and country the line already names is the exit. To put a profile in a particular place, paste the Shifter endpoint for that place; to keep one exit for a profile, paste one of Shifter's sticky endpoints.

What Mosaic does with the Shifter exit

Once a Shifter proxy is checked, Mosaic reads the public address and city it comes out at and matches the profile to it: the timezone, the languages and the geolocation are set from the exit, not from the proxy's label. Mosaic also stops WebRTC from going around the Shifter proxy, so a page cannot read your real address that way. The authentication runs through a local relay, so a Shifter login works over HTTP, HTTPS and SOCKS5, including SOCKS5 with a username and password, which Chrome cannot log in to on its own.

The honest limits

Mosaic does not sell proxies or proxy traffic; the Shifter bill is between you and Shifter. Mosaic reads Shifter's format from the published documentation and has not run it against a live Shifter account, so the row shows an untested badge; the format may be out of date if Shifter has changed it. Whether to run several accounts on Shifter exits is the platform's rule, not ours: Mosaic keeps accounts you are entitled to run apart, and does not change what a site allows.

If you are still choosing a seller, the proxies worth using with an anti-detect browser sets out what to look for, and rotating against sticky sessions explains which kind each job wants. Mosaic Pro is $49 a month for any number of profiles, with the first 14 days free, and Free holds 3 profiles.
