## Paste a whole proxy list and deal it out across your profiles

Paste a list in any common format, or a CSV with a header row. Mosaic reads every line, says why any line was refused, and assigns the result to as many profiles as you select.

*Bulk import: every line read, new and duplicate proxies told apart, each one checked after import.*

## Bulk proxy import and assign, step by step

### Paste or drop a list

host:port:user:pass, URLs, user:pass@host, CSV, TSV and semicolon tables with a header row, and IPv6 are all read. Duplicates are dropped.

### Read the refusals

A line that cannot be read is listed with its reason, so one bad line never sinks the other 199.

### Assign

Give selected profiles one proxy, deal a list round-robin, give each a unique one (refused if there are not enough), or match by country.

## The smaller things it does

### Rotate now

For a mobile proxy with a change-IP link, Mosaic calls the link itself and checks the proxy before and after, so you see whether the address actually changed.

### Export

Proxies come back out as URLs, colon lines or CSV, in a form the importer reads again.

### Check after import

Imported proxies can be checked straight away, with a name prefix and tags to keep a batch together.

## Works with

### A profile does not open until its proxy has answered

No profile opens behind a proxy that has not answered.

### Paste one gateway line. Every profile mints its own exit.

One gateway line, a separate exit for every profile.

### Make 500 profiles in one go, then work on all of them at once

500 profiles per batch; start, edit and type into many.
