electerm is a cross-platform terminal and remote connection client built with Electron and JavaScript, supporting a wide range of protocols including SSH, SFTP, FTP, Telnet, serial ports, RDP, VNC, and Spice. It aims to be a versatile alternative to commercial clients like Termius or MobaXterm, running on Linux, macOS, and Windows with native packaging for both x64 and ARM64 architectures.
What electerm does and how it’s built
At its core, electerm is an Electron desktop application that combines terminal emulation with remote file transfer and desktop protocols. It supports typical terminal connections like SSH and Telnet, but also extends to graphical remote desktops via RDP and VNC, plus Spice for virtualization consoles. File transfer protocols like SFTP and FTP are integrated, alongside serial port communication.
The codebase is written in JavaScript using Vite as the development server and build tool, wrapped inside Electron for the desktop environment. Packaging is handled by electron-builder, targeting multiple OSes and CPU architectures. This means electerm bundles its UI and backend logic into a single app that works across platforms.
An interesting architectural aspect is the dual-process development environment. When developing, you run the Vite dev server in one terminal and the Electron app in another. This separation allows hot module reloading and faster frontend iteration but also brings complexity in dependency management and build orchestration.
The app supports syncing bookmarks via external services like GitHub or Gitee gists and WebDAV. It also integrates AI assistants (DeepSeek, OpenAI) through MCP widgets, showing an ambition beyond basic terminal functions.
Managing complexity: the dual-process dev setup and dependency tradeoffs
What distinguishes electerm technically is the way it manages a large Electron app with many native protocol bindings and third-party integrations, all in JavaScript. Electron apps tend to accumulate dependencies, especially when dealing with native modules like serial port communication or complex protocols.
The dev setup requires Node.js version 24.x and running npm with the --legacy-peer-deps flag. This flag is a workaround for dependency conflicts that arise in large projects with many interdependent packages. It hints at the challenges of maintaining up-to-date dependencies in an Electron environment where native bindings often lag behind.
The parallel running of Vite and Electron processes is a tradeoff between developer experience (fast frontend refresh) and complexity (multiple terminal windows, manual orchestration). While this setup improves UI development speed, it can be cumbersome to newcomers.
Code quality appears solid for an open-source project of this size (14k stars), with a clear structure separating frontend and backend logic and well-organized protocol handlers. However, the reliance on legacy peer dependencies and the need for a specific Node.js version indicate a maintenance burden.
File transfer support with Zmodem and Trzsz protocols adds practical value for users needing robust terminal file uploads/downloads. The support for multiple remote desktop protocols alongside terminal sessions is a notable feature that sets electerm apart from many simpler terminal clients.
Install and quick start commands
- For Mac user:
brew install --cask electerm - With snap:
sudo snap install electerm --classic - For some Linux distributions, electerm can be found in the OS default app store (Ubuntu, Deepin, Mint, etc.).
- If the rpm, deb, or snap releases don’t work on your Linux OS, try the tar.gz or .appImage releases.
- For Windows users, electerm is available through the Windows Store, and command-line installers like winget and scoop are recommended.
The repo recommends using Node.js 24.x with --legacy-peer-deps to manage dependencies properly when running the app in development mode.
why electerm is worth exploring
electerm is a solid open-source alternative for developers and sysadmins who need a multi-protocol terminal client beyond plain SSH. Its support for remote desktop protocols, serial ports, and integrated AI widgets makes it a versatile tool for complex workflows.
The dual-process development setup reveals the inherent complexity of maintaining a large Electron app with many native dependencies. This is a practical example of the tradeoffs involved in building cross-platform desktop apps with modern JavaScript tooling.
While the requirement for legacy peer dependency flags and specific Node.js versions can be frustrating, it’s understandable given the native bindings and protocol complexity.
If you’re looking for a free, cross-platform terminal client with robust protocol support and don’t mind navigating the occasional Node.js dependency quirks, electerm is worth a look. It’s especially relevant for users who want more than just SSH — including SFTP file transfers, remote desktop access, and serial port management — all in one app.
For developers interested in Electron apps that push the boundaries of protocol integration, electerm’s codebase provides useful insights into dependency management and dev workflow tradeoffs in a mature open-source project.
