How to Set Up a Proxy in Lalicat Browser
Lalicat is a special type of browser known as an anti-detect browser. It utilizes multiple isolated instances of Chrome-based browsers, each acting as a separate device with its own unique IP address, browser profile, and fingerprint.
One of the main features of Lalicat is the ability to manage multiple browser profiles simultaneously, allowing users to have individual accounts for each profile. This helps simulate the use of different devices and prevents accounts from being linked to a single user. By enhancing your privacy and uninterrupted connection, Lalicat is useful for tasks like overseas e-commerce, web scraping, and brand protection.
Lalicat needs four values: host, port, login and password. Paste them in this form, or in separate fields if the tool asks for them separately:
Below: the exact format with country targeting, the setup steps, how to confirm the exit IP, and what every error message means.
What you need before you start
A Lalicat account, a DataImpulse plan with traffic on it, and your proxy credentials from the dashboard.
| Field | Value | Notes |
|---|---|---|
| Host | gw.dataimpulse.com | one gateway for residential and mobile |
| Port | 823 for HTTP and HTTPS, 10000 for SOCKS5 | the protocol and the port must match |
| Login | your base login, with targeting appended | LOGIN__cr.us;sid.prof01 |
| Password | from the dashboard | a trailing space is the most common cause of a failed test |
Lalicat proxy format
Everything lives in one line, and targeting is appended to the login rather than set in a separate field. Two
underscores start the parameters, semicolons separate them.
If Lalicat asks for host, port, login and password in separate fields, split the same line: the host is
gw.dataimpulse.com, the port is 823, and the whole LOGIN__cr.us;sid.prof01 part goes into the username field.
Setting up a proxy in Lalicat, step by step
To install Lalicat, follow these simple steps:
- Go to the official Lalicat website.
- Download the setup file.
- Run the installation setup and follow the instructions.
To configure proxies in Lalicat, follow these steps:
- After installing Lalicat, open the application and create a new account or log in if you already have one.
- On the home screen, click on “Browser List” and then select “+ Add Browser Profile” to set up a new browser instance.
- Enter a name for the browser profile and choose a simulated operating system. Additionally, adjust any other settings that are necessary and relevant to the task you have planned.
- Under the proxy settings, choose HTTP as the proxy protocol to set up your proxy configuration.
Residential Proxies
Connection type: HTTP proxy
New address: gw.dataimpulse.com
Port: 823
- Input your DataImpulse user’s Username and Password.
- To finalize the configuration, click on the Save button. Once saved, you can open the browser and begin using it.
That’s it! You have successfully integrated your DataImpulse proxies with Lalicat.
How to check the proxy actually works
A green test button only means the credentials authenticated. It does not mean you got the country you asked for.
- Exit IP: open an IP lookup service through Lalicat and compare country and city with your targeting.
- Timezone and locale: they should follow the exit node, not your own machine.
- Stickiness: reconnect and check that the same session id returns the same address.
A wrong country on the first request or two is normal while the session settles. If it is still wrong after three
attempts, the targeting parameter is malformed.
Lalicat proxy not working: errors and fixes
| What you see | What it actually is | Fix |
|---|---|---|
| 407 Proxy Authentication Required | wrong password, or no traffic left | re-copy the password without spaces, check the balance |
| Connection failed or refused | protocol and port do not match, or a typo in the host | 823 for HTTP, 10000 for SOCKS5, host without a protocol prefix |
| Test passes, wrong country | targeting written into the wrong field | parameters belong on the login after two underscores |
| IP changes mid session | no session id, or the TTL expired | add sid and sessttl, and remember sessttl is in seconds |
| Two profiles show the same IP | the same session id reused | one profile, one sid, forever |
Rotating, sticky or mobile: which one for which job
| Job | Setup | Why |
|---|---|---|
| One account per profile, long sessions | sticky: sid plus sessttl | the platform sees one stable location |
| Registering many accounts | sticky, a new sid per profile | each account needs its own IP history |
| Scraping or checking pages at volume | rotating: no sid | a fresh IP per request spreads the load |
| Mobile first platforms | mobile pool, sticky | carrier IPs carry more trust on app centric platforms |
Mobile proxies use the same host, port and login format. Only the pool behind your login changes.
FAQ
How do I add a proxy to Lalicat?
Open the proxy settings, choose HTTP, and enter gw.dataimpulse.com as the host with port 823, then your login and password from the dashboard. If Lalicat takes one line, paste gw.dataimpulse.com:823@LOGIN:PASSWORD.
What proxy format does Lalicat use?
Host, port, login and password. Country and session parameters are appended to the login after two underscores, for example LOGIN__cr.us;sid.prof01, not entered in a separate field.
Why does the Lalicat proxy test fail?
Most often the password carries a trailing space, or the port does not match the protocol. Use 823 for HTTP and HTTPS and 10000 for SOCKS5, and copy the credentials straight from the dashboard.
Can I use mobile proxies with Lalicat?
Yes. The host, the port and the login format are identical. Only the pool your plan gives you is different.
Can two Lalicat profiles share one proxy?
Technically yes, in practice never do it. Two profiles on one IP link the accounts together. Give each profile its own session id.
The same connection line works in our other setups: Dolphin Anty, Puppeteer and Multilogin. See how residential proxies and mobile proxies differ before you pick a pool.
