DeepSeek-Reasonix System Requirements: Cross-Platform Installation Guide

DeepSeek-Reasonix runs as a statically linked single binary on macOS, Linux, and Windows supporting both amd64 and arm64 architectures, requiring no external runtime dependencies beyond outbound HTTPS access to DeepSeek's API.

DeepSeek-Reasonix is a cross-platform CLI tool developed in the esengine/DeepSeek-Reasonix repository. It delivers reasoning capabilities through a self-contained Go binary that eliminates the need for language-specific runtimes like Python or Node.js. Whether you download a pre-built release or compile from source, understanding the system requirements ensures smooth deployment across development and production environments.

Platform and Architecture Support

DeepSeek-Reasonix targets the three major desktop operating systems with native binaries for both Intel and ARM processors.

Supported Operating Systems

The application officially supports macOS, Linux, and Windows. According to the repository's README.md, pre-built release archives contain platform-specific binaries organized under darwin, linux, and windows directories. The official installer (npm i -g reasonix) automatically selects the correct binary for your operating system by detecting the platform at install time.

CPU Architecture Compatibility

The binary supports 64-bit architectures exclusively:

• amd64 (also known as x86_64)
• arm64 (also known as aarch64)

Each release archive contains all four combinations of OS and architecture, allowing the tool to run on both Intel-based Macs and Apple Silicon devices, as well as ARM-based Linux servers and Windows machines.

Runtime Dependencies and Environment

One of the primary advantages of DeepSeek-Reasonix is its minimal runtime footprint compared to interpreter-based tools.

Zero External Runtime Requirements

The binary is statically linked with CGO_ENABLED=0 during the build process, as defined in the Makefile. This means you do not need Go, Python, Node.js, or any C libraries installed on the target machine. The binary ships with everything it needs, including a tiny TOML parser for configuration files. At runtime, it only requires read access to a reasonix.toml config file (or creation of one via the setup wizard) and optional access to a global .env file for API keys.

Network Requirements

The application requires outbound HTTPS access to DeepSeek's API endpoints, specifically https://api.deepseek.com. No inbound ports need to be opened, and the tool operates entirely as a client-side application.

Storage and Configuration Paths

DeepSeek-Reasonix requires a user-writable directory referred to as the "Reasonix home" for storing configuration, credentials, caches, and session data. As documented in docs/CONFIG_PATHS.md, the default locations are:

• macOS/Linux: ~/.reasonix
• Windows: %APPDATA%\reasonix

The directory is created automatically when you run reasonix setup for the first time.

Build Requirements (From Source)

If you choose to compile the binary yourself rather than using a pre-built release, you will need specific build tools.

Go Version and Build Flags

The go.mod file in the repository root pins the Go version to 1.22 or higher. The build process explicitly disables CGO (CGO_ENABLED=0), eliminating the need for GCC or system-specific C libraries during compilation. This ensures the resulting binary is truly portable across different Linux distributions and macOS versions.

Cross-Compilation Makefile Targets

The Makefile provides standardized build commands:

• make build – Compiles a static binary for the current platform
• make cross – Generates binaries for all supported OS/architecture combinations

These targets handle the GOOS and GOARCH environment variables automatically, producing optimized binaries without external dependencies.

Optional Development and UI Dependencies

While the core CLI requires no additional components, certain optional features have specific dependencies.

Desktop UI WebView Requirements

The desktop interface mode (documented in desktop/README.md) requires a native webview runtime:

• macOS: Uses the native WebKit framework (included in the OS)
• Windows: Requires Edge WebView2 runtime (usually present on modern Windows 10/11 systems)
• Linux: Requires WebKit/GTK libraries (libwebkit2gtk-4.0)

These are only necessary if you intend to use the graphical interface rather than the command-line tools.

Installation and Verification

To verify your system meets the requirements and install the tool:

# Check your architecture (should return x86_64 or aarch64/arm64)

uname -m

# Install via npm (downloads appropriate pre-built binary)

npm i -g reasonix

# Verify installation and show version

reasonix --version

# Run interactive setup to create config directory

reasonix setup

Create a minimal configuration file at ~/.reasonix/config.toml (or %APPDATA%\reasonix\config.toml on Windows):

default_model = "deepseek-flash"

[[providers]]
name = "deepseek-flash"
kind = "openai"
base_url = "https://api.deepseek.com"
model = "deepseek-v4-flash"
api_key_env = "DEEPSEEK_API_KEY"

Export your API key and test the installation:

export DEEPSEEK_API_KEY=sk-your-key-here
reasonix run "write a Go hello world program"

Summary

• DeepSeek-Reasonix operates as a single static binary with no runtime dependencies.
• Supports macOS, Linux, and Windows on both amd64 and arm64 architectures.
• Requires Go 1.22+ only if building from source; end-users need only a supported OS.
• Needs outbound HTTPS to api.deepseek.com and a writable directory for configuration storage.
• Optional desktop UI requires platform-specific WebView components (WebKit on macOS/Linux, Edge WebView2 on Windows).

Frequently Asked Questions

Do I need to install Go to use DeepSeek-Reasonix?

No. If you install via npm i -g reasonix or download a pre-built binary from the GitHub releases page, you do not need Go installed. The binary is statically linked and self-contained. You only need Go 1.22+ if you are compiling the source code yourself using the Makefile targets.

Can I run DeepSeek-Reasonix on ARM-based Macs or Raspberry Pi?

Yes. The release archives include arm64 (or aarch64) binaries that support Apple Silicon Macs and ARM64 Linux devices like the Raspberry Pi 4/5. The uname -m command will output arm64 or aarch64 on compatible systems, and the installer automatically selects the correct architecture.

What network access does DeepSeek-Reasonix require?

The application requires outbound HTTPS access to https://api.deepseek.com to communicate with the DeepSeek API. No inbound network ports are required, and the tool functions correctly behind standard corporate firewalls provided HTTPS traffic is permitted. All API keys are read from local environment variables or the .env file, never transmitted elsewhere.

Where are configuration files stored on different platforms?

According to docs/CONFIG_PATHS.md, the default configuration directory is ~/.reasonix on macOS and Linux, and %APPDATA%\reasonix on Windows. This directory stores your reasonix.toml configuration, API credentials, session caches, and temporary data. You can customize this path by setting the REASONIX_HOME environment variable before running the application.
