Introduction

Simprint is a professional anti-detect browser designed for secure multi-account management. It creates isolated browser environments with unique fingerprints, preventing platforms from detecting account associations.

Whether you're managing e-commerce stores, advertising accounts, or social media profiles, Simprint provides the security and isolation you need to operate at scale.

Key Features

Unique browser fingerprints for each profile (Canvas, WebGL, Audio, Fonts)
Complete environment isolation with separate cookies, cache, and storage
Built-in proxy management with support for HTTP, SOCKS5, and residential proxies
Team collaboration with role-based access control
Cloud sync for seamless profile sharing across devices

Installation

Simprint is currently available for Windows. Download the installer from our official website and follow the installation wizard.

System Requirements

Component	Minimum	Recommended
Operating System	Windows 10 64-bit	Windows 11 64-bit
RAM	8 GB	16 GB+
Storage	500 MB	2 GB+ SSD
CPU	Dual-core 2.0 GHz	Quad-core 3.0 GHz+

For optimal performance when running multiple browser profiles simultaneously, we recommend using an SSD and at least 16GB of RAM.

Quick Start

Get up and running with Simprint in just a few minutes. Follow these steps to create your first browser profile.

Step 1: Create a New Profile

Click the "New Profile" button in the main dashboard. Give your profile a descriptive name and select the operating system and browser type to emulate.

Step 2: Configure Fingerprint

Simprint automatically generates a unique fingerprint for each profile. You can customize specific parameters or use the "Randomize" button for a completely new identity.

// Example fingerprint configuration
{
  "userAgent": "Mozilla/5.0...",
  "screenResolution": [1920, 1080],
  "timezone": "America/New_York",
}

Step 3: Add Proxy (Optional)

For enhanced anonymity, add a proxy to your profile. Simprint supports HTTP, HTTPS, SOCKS4, and SOCKS5 proxies.

Step 4: Launch Browser

Click "Start" to launch the browser with your configured profile. Each profile runs in complete isolation from others.

Always use a unique proxy IP for each profile to maximize anonymity and prevent correlation.

Browser Profiles

Browser profiles are the core of Simprint. Each profile represents a completely isolated browser environment with its own fingerprint, cookies, local storage, and cache.

Profile Management

Create unlimited profiles with unique identities
Clone existing profiles to quickly duplicate settings
Organize profiles into folders and groups
Add tags for easy filtering and search
Export and import profiles for backup or migration

Simprint provides comprehensive fingerprint customization to ensure each browser profile has a unique, consistent identity that passes all major detection platforms.

API Reference

Simprint exposes a local HTTP API after you enable API access in the client. The API is designed for local automation and tool integration.

Base URL

The local API listens on the port configured in the client. By default it binds to 127.0.0.1 unless remote access is enabled.

http://127.0.0.1:{port}/api/local

Authentication

Every request must include the local API key in the sp-api-key header. The key can be generated and rotated from the API & AI page.

sp-api-key: YOUR_LOCAL_API_KEY

Frequently Asked Questions

How many profiles can I create?

There is no limit to the number of profiles you can create. However, running multiple profiles simultaneously will consume more system resources.

Does Simprint pass all detection tests?

Simprint is designed to pass all major browser fingerprint detection platforms including CreepJS, FingerprintJS, and Pixelscan. We continuously update our fingerprint engine to stay ahead of new detection methods.

Can I use my own proxies?

Yes, Simprint supports any HTTP, HTTPS, SOCKS4, or SOCKS5 proxy. You can also integrate with popular proxy providers through our API.
