Lalicat puts the proxy inside basic configuration of the browser profile. Choose the protocol in proxy settings, type the gateway host in IP address and the port in Port, then the login in Proxy Login Name and Proxy Login Password, or use Paste proxy information with the full line. Check the network tests it.
Profile List → Add Browser Profile → basic configuration → proxy settings
Paste proxy information takes IP:port:Username:Password in one line.
Open Lalicat, go to Profile List and click Add Browser Profile at the top. Set the name, group, OS and User-Agent as you like, then scroll to proxy settings in basic configuration.

In proxy settings choose HTTP for the HTTP port or SOCKS5 for the SOCKS5 port. Type the gateway host in IP address, the port in Port, the username in Proxy Login Name and the password in Proxy Login Password. Or click Paste proxy information and paste the whole line.

Click Check the network next to the protocol. A green result shows the country, region and city of the exit IP. Finish the profile and click Save in the lower-right corner.

Check the network, next to the protocol selector. A green line names the exit country, region and city.
Launch the profile from Profile List. If the check is red, verify the protocol, the port and that the plan is still active.
Copy the line from the dashboard (Proxies, your plan, the proxy generator) rather than typing it: it already carries the country, the session id and the session length in the username. The table shows what each field holds.
| Plan | Host | HTTP port | SOCKS5 port | Username shape |
|---|---|---|---|---|
| Residential Premium | residentialpremium.quantumproxies.io | 8080 | 1080 | USER-country-us-sid-k3f9a1b2-ttl-60m |
| Residential Basic | residentialboson.quantumproxies.io | 9000 | from the generator | USER-country-us |
| Mobile | mobile-us.quantumproxies.io (also -eu, -as, ww) | 8080 | 1080 | USER-country-us-type-mobile |
| Datacenter (per GB) | datacenterboson.quantumproxies.io | 9999 | 10000 | USER-type-datacenter-country-de |
| IPv6 | ipv6.quantumproxies.io | 1001 | from the generator | USER-country-us-package-ipv6 |
| ISP (dedicated IP) | the IP of your line | 8000 | on the plan page | the line's own login |
The password is the one the generator prints next to the username. Pick HTTP or SOCKS5 in the tool and use the port of that column; a port from the other column is the most common reason a check fails. USER and the session id are placeholders for your own values.
IP:port:Username:Password on one line, as the hint under the button says. The host name of a gateway works in the IP place.
HTTP with the HTTP port, SOCKS5 with the SOCKS5 port. Skip HTTPS: it expects a TLS proxy, which our gateways are not.
Creat in Bulk makes several profiles, but they would share one proxy. Create them, then edit each profile's proxy with its own sticky line.
Skip the marketing. QuantumProxies.io publishes a machine-readable site map, Markdown for every page, a free MCP server, and APIs billed from the same balance as your proxies.
