Desktop workspace for browser environments, proxy resources, and automation workflows.
English | 简体中文
Simprint is a desktop workspace for browser-driven operations, designed to organize browser profiles, proxy resources, automation flows, and local runtime capabilities in one place.
It is intended for individuals and teams that need to maintain multiple browser work environments over time, including scenarios such as cross-border operations, account management, automated task execution, and shared resource coordination. With a unified desktop entry point, Simprint helps manage environment lifecycles more consistently, connect external resources, and build reusable workflows around daily operations.
Most browser automation and browser workspace products are still shaped by a few recurring limitations:
- Closed-source products that hide implementation details and reduce long-term trust.
- Cloud-only products that force operational workflows and sensitive data into third-party infrastructure.
- Anti-user product decisions that restrict ownership, portability, and control over browser environments.
- Rigid systems that are difficult to extend, automate, or integrate into custom workflows.
Simprint is being built to take a different direction: an open, programmable browser workspace for developers, researchers, operators, and automation-heavy teams. The goal is to make browser environments easier to control locally, easier to integrate with surrounding tools, and easier to evolve as workflows become more technical and more AI-assisted.
- Isolated browser environments: Run multiple browser workspaces with separated state and operational boundaries.
- Persistent browser profiles: Keep long-lived browser profiles, account context, and workspace state organized over time.
- Proxy orchestration: Connect, assign, and manage proxy resources across environments and workflow scenarios.
- Fingerprint configuration: Control environment-level browser characteristics and continue refining fingerprint-related behavior.
- Local automation runtime: Build and run repeatable browser workflows for daily operations and task execution.
- Chromium-based desktop runtime: Run the workspace through a local Chromium-oriented Tauri + Rust desktop runtime with integrated frontend and system-level services.
- Syncer: Coordinate multiple running environments, choose a master session, and mirror interaction flows across selected windows.
- RPC bridge: Use the built-in Tauri command bridge between the React frontend and Rust services for desktop-native operations and orchestration.
- Local API: Expose workspace resources such as environments, proxies, tags, groups, and browser kernels through a local runtime API.
- MCP: Run a local Model Context Protocol service so external AI clients can connect to Simprint-managed tools and workspace resources.

cargo tauri dev --features developmentBuild a production package:
cargo tauri build --features productionSimprint was originally developed as a commercial product. It is now being transitioned into an open-source project, and the current open-source edition is intended to provide all core functionality without feature gating.
Some billing-related UI, upgrade prompts, or commercial entry points may still appear in the product as remnants of the previous commercial model. These interfaces are being phased out and will be removed over time, while the related functionality will remain openly available in the community edition.
- AI workflows: Expand AI-assisted operational flows and agent-oriented task orchestration.
- Private deployment: Improve support for self-hosted and enterprise-controlled deployments.
- Fingerprint research: Continue refining browser environment controls, compatibility, and research depth.
- Automation SDK: Provide a more reusable interface for building and integrating automation capabilities.
Most users of the open-source edition will rely on community-hosted services, and related data may therefore be stored on community-managed servers. The community does not proactively disclose user data to third parties, but each user remains responsible for assessing their own data risk and should avoid submitting sensitive information whenever possible.
