Simprint is an open-source, programmable browser workspace designed for isolated environments, automation workflows, proxy orchestration, and browser fingerprint research. It targets developers, researchers, and automation-heavy teams needing to manage multiple browser work environments locally, offering enhanced control, portability, and integration capabilities for cross-border operations, account management, and automated tasks.

How It Works

Simprint utilizes a local Chromium-based desktop runtime built with Tauri and Rust, featuring an integrated React frontend. It provides isolated browser environments with persistent profiles, robust proxy orchestration, and fine-grained fingerprint configuration. A local automation runtime enables the creation and execution of repeatable workflows. Advanced features include a 'Syncer' for coordinating multiple sessions and mirroring interactions, an RPC bridge for frontend-Rust communication, a local API for managing workspace resources, and an MCP service for AI client integration.

Quick Start & Requirements

• Prerequisites: Node.js 20+, pnpm, Rust toolchain, and Tauri system prerequisites for your platform.
• Install (Self-hosted server): curl -fsSL https://raw.githubusercontent.com/Simprint/simprint/main/deploy/install-server.sh | bash
• Run locally: pnpm install, cp src-tauri/config.example.toml src-tauri/config.development.toml, cargo tauri dev --features development.
• Links: No direct quick-start or demo links provided, but CONTRIBUTING.md is referenced for development setup.

Highlighted Details

• Isolated browser environments with separated state and operational boundaries.
• Persistent browser profiles for long-lived account context and workspace state.
• Proxy orchestration for connecting, assigning, and managing proxy resources across environments.
• Fingerprint configuration for controlling environment-level browser characteristics.
• Local automation runtime for building and running repeatable browser workflows.
• Syncer for coordinating multiple running environments and mirroring interaction flows.
• Local API exposing workspace resources like environments, proxies, and browser kernels.
• MCP service for external AI clients to connect to Simprint-managed tools.

Maintenance & Community

Simprint is undergoing an active open-source transition, seeking early contributors and future maintainers. Community discussions and updates are encouraged via their community channels. The roadmap includes expanding AI workflows, refining fingerprint research, and developing an Automation SDK. Core components like simprint-runtime and simprint-browser-kernel are being prepared for broader collaboration.

Licensing & Compatibility

This project is licensed under the GNU Affero General Public License v3.0 (AGPLv3). Use cases not complying with AGPLv3 obligations, such as distributing modified versions or providing modified versions as a closed-source service, require a commercial license.

Limitations & Caveats

Remnants of a previous commercial model, including billing-related UI and upgrade prompts, may still appear but are being phased out. Users relying on community-hosted services are responsible for assessing their own data risk, as data may be stored on community-managed servers. The project is actively seeking contributions, indicating ongoing development and potential areas needing community support.
