Overview

Reflex is a cross-platform SSH desktop client built around real server work: connect, inspect, edit, deploy, recover, and continue with the same context after switching tasks or reopening the app.

It combines a focused terminal workspace with practical infrastructure tools and an Agent that can execute visible server operations without exposing hidden reasoning. Connection profiles, preferences, provider credentials, and Agent history remain local to the application.

Great software is the sum of every thoughtfully designed detail.

Product tour

Agent
Visible tool steps, commands, results, and streaming responses.

Docker
Containers, images, ports, logs, and lifecycle actions.

Connection flow
SSH connection, terminal, file tree, and monitoring load into a ready workspace.

Agent flow
Prompt, tool timeline, terminal output, and streamed answer in one continuous run.

Appearance
Themes, accent color, radius, and fonts.

Terminal
Rendering, cursor, typography, and scrollback.

Why Reflex

• One remote workspace: terminal, files, Docker, monitoring, and Agent actions stay side by side.
• Agent-native execution: describe an outcome and follow the visible commands, progress, approvals, and results.
• Recoverable sessions: terminal state and Agent conversations survive task switching and application restarts.
• Local-first configuration: connection and provider settings are stored on the device.
• Cross-platform releases: packaged for Windows, macOS Intel/Apple Silicon, and Linux.
