Why Not Just Use tmux?
Explore the trade-offs between terminal multiplexers and modern IDEs. Learn why not just use tmux and when a spatial workspace like Deska fits your workflow.

For many developers, the terminal is the primary operating system. The question of why not just use tmux often arises when new productivity tools enter the market. As a rock-solid terminal multiplexer, tmux has defined how engineers manage persistent sessions and window splits for decades. However, the shift toward AI assisted development and complex frontend workflows has introduced new requirements that traditional text based multiplexers were not designed to handle. Understanding the strengths of tmux and its inherent limitations helps in deciding whether to stick with a purely CLI approach or adopt a spatial workspace.
The Case for Staying in the Terminal
The longevity of tmux is not accidental. It solves three specific problems with clinical efficiency: session persistence, window management, and resource economy. When you run a process inside a tmux session on a remote server, that process continues to execute even if your SSH connection drops. This is a fundamental requirement for backend engineers and system administrators who cannot afford to have a long running migration or build interrupted by a flicker in connectivity.
Furthermore, tmux is extremely lightweight. It runs on almost any Unix like environment with negligible overhead. For developers who prefer a keyboard centric workflow, the ability to split panes and navigate between them using prefix keys is a major advantage. It allows for a high degree of focus by removing the distractions of a graphical user interface. If your work is exclusively text based and you have mastered the complex key bindings, the speed of navigation is difficult to beat.
Where the Terminal Multiplexer Reaches Its Limit
Despite its power, tmux operates within the constraints of the terminal emulator. This creates friction in several modern development scenarios:
- Visual Context: Modern web development requires a browser. While lynx or w3m exist, they are not viable for debugging a React application. Moving between a tmux session and a Chrome window breaks the mental flow and requires constant window switching.
- Information Density: Terminal panes are grid based. You can split them vertically or horizontally, but you cannot easily overlap them or place them in a non linear arrangement. As projects grow, the "window within a window" abstraction of tmux can become cognitively taxing to track.
- Media and Rich Text: Notes, diagrams, and documentation often include images or formatted text. Forcing these into a terminal requires plugins that often feel like hacks rather than native features.
The Problem of Spatial Memory
Humans have a strong sense of spatial memory. We remember where we put things in a physical room better than we remember which numbered tab contains a specific file. In tmux, every pane is hidden behind a session name or a window index. In a spatial environment, you can use your peripheral vision to keep track of logs while you write code.
Deska as a Spatial Alternative
Deska occupies a middle ground between the minimalist terminal and the heavy IDE. It is a local-first desktop application that provides an infinite canvas. Instead of being locked into a rigid grid of terminal panes, you can place elements anywhere in a 2D space.
The workspace in Deska allows you to combine different types of tools that tmux cannot host natively. You can have a terminal running your server, a code editor based on Monaco, and a live browser window all visible at the same time. Because it uses an infinite canvas, you can zoom out to see the entire architecture of your current task or zoom in on a specific terminal.
Integrated AI Agents
One of the most significant shifts in development is the rise of AI agents. Running tools like Claude Code or OpenCode inside a standard terminal works, but the output can quickly scroll away, making it hard to reference previous instructions. Deska allows you to run these agents in dedicated panels. You can place the agent thread next to your code editor and your terminal, creating a feedback loop that does not require constant scrolling or tab switching.
Remote Access and Mobility
A common argument for tmux is the ability to attach to a session from anywhere. Deska addresses this through a mobile application. Instead of relying on raw SSH, the mobile app connects to your primary machine via a secure relay. This allows you to monitor long running tasks, check terminal output, or continue a conversation with an AI agent from your phone. The devices pair directly, meaning you do not have to expose ports or configure complex firewalls to maintain access to your terminals.
Comparing the Workflows
When choosing your primary tool, consider the following comparison of how tmux and Deska handle common developer tasks:
| Feature | tmux | Deska |
|---|---|---|
| Interface | Text-based grid | Infinite canvas |
| Persistent Sessions | Native via server/client | Native local-first storage |
| GUI Applications | Not supported | Integrated browser panels |
| AI Integration | Standard CLI output | Dedicated agent panels |
| Navigation | Keyboard shortcuts | Keyboard and spatial zooming |
| Configuration | .tmux.conf (DSL) | GUI and settings |
The choice is not necessarily binary. Many developers use tmux inside Deska panels to take advantage of session management while benefiting from the canvas layout.
The Importance of Local First Data
A major concern for developers is privacy and data sovereignty. This is why tmux remains popular; it is a local tool. Deska follows this philosophy by being local-first. Your code, your terminal logs, and your session data remain on your machine. If you choose to use AI features, you can use your own API keys, ensuring that you have full control over your development environment and its costs.
Frequently Asked Questions
Can I use my existing tmux sessions in Deska?
Yes, you can run tmux within any terminal panel in Deska. This allows you to keep your remote session persistence while taking advantage of the spatial canvas for other tasks like note taking or browsing documentation.
Is Deska a replacement for VS Code?
Deska includes a code editor based on Monaco, the same engine that powers VS Code. While it provides a robust editing experience, it is designed to be part of a broader workspace. It functions best when you need to see your editor, terminals, and browser-widgets simultaneously.
How does the mobile relay keep my data secure?
The mobile app pairs directly with your desktop. It uses a secure relay to bypass the need for port forwarding, but the data remains encrypted. Your files and sessions are not stored on external servers; the relay simply facilitates the connection between your own devices.
Getting Started with a Spatial Workspace
If you find yourself constantly switching between tabs or getting lost in a sea of terminal splits, it might be time to try a different approach. You can maintain your command line efficiency while gaining a visual overview of your entire project.
