electerm review: an SSH, SFTP, RDP and serial client for old and new desktops

What electerm is, and the machines it targets

electerm is a desktop client that puts a terminal and a file manager in the same window. The README describes it as a "terminal/ssh/sftp/ftp/telnet/serialport/RDP/VNC/Spice client" for Linux, Mac, Windows, Android, HarmonyOS and iOS. That list matters more than the word terminal. Most terminal emulators stop at a shell; electerm also speaks SFTP and FTP for file transfer, telnet and serialport for network gear and embedded boards, and RDP, VNC and Spice for graphical desktops. If your day involves jumping between a terminal, an SFTP client and a remote desktop viewer, electerm is trying to collapse those into one application.

The second differentiator is the platform matrix. The README claims Windows 7 and later on x64 and ARM64, macOS 10.15 and later, Linux on x64, arm64 and Loong64, and older Linux with glibc 2.17 or newer such as UOS, Kylin and Ubuntu 18.04. HarmonyOS and iOS are listed alongside Android. That is an unusually wide net. It is the reason the project exists in its current form: engineers maintaining equipment or working inside locked-down enterprise images often cannot run a client that requires a recent Chromium and a modern glibc. electerm's answer is to keep building for those targets.

Who it is for, then: infrastructure and network engineers who need many protocols in one tool, and anyone whose fleet includes machines that mainstream clients have dropped. It is not aimed at developers who want a fast local shell with GPU rendering; nothing in the README suggests that is the goal.

How the connection, transfer and sync layers fit together

The repository is a single Node/Electron application. package.json lists the entry point as app.js, with build scripts under build/bin and application source under src/. The npm bin entry is npm/electerm, which is how the global npm install launches the app. So the runtime model is the standard Electron one: a Node process for the main window and its integrations, and a renderer for the UI. The README does not describe an internal plugin architecture or a separate daemon.

On top of that shell, electerm layers several capabilities. Sessions are stored as bookmarks, and the README says bookmarks, themes and quick commands can be synced to a GitHub or Gitee secret gist, WebDAV, a custom server, or electerm cloud. That gives you a portable profile across machines without running your own database. Authentication supports public key plus password. SSH tunnels are supported, as are Zmodem (rz, sz) and Trzsz (trz, tsz), the latter noted as compatible with tmux. A global hotkey toggles window visibility, with ctrl + 2 as the default, which is the Guake-style workflow.

Two integration points stand out. First, deep links: the README says connections can be opened with URLs such as ssh://user@host:22 or telnet://192.168.2.31:34554, which lets another application hand a host to electerm. Second, an MCP widget, documented in the project wiki, exposes electerm to AI assistants and external tools. There is also an AI assistant integration supporting DeepSeek, OpenAI and other APIs for command suggestions and script writing. Those features are optional; the core client works without them.

Installing electerm on macOS, Windows and Linux

The README lists per-platform install paths rather than a single installer. On macOS the Homebrew cask is the documented route. Running it installs the application into /Applications like any other cask.

brew install --cask electerm

On Linux there are two options. Snap is the shortest, and the --classic flag is required because the app needs access outside the sandbox.

sudo snap install electerm --classic

For Debian and Ubuntu systems the project also publishes an apt repository; the README points to https://repos.electerm.org/deb, and there is a matching rpm repository at https://repos.electerm.org/rpm. The README warns that on some Linux distributions the rpm, deb or snap release may not work, in which case you should try the tar.gz or .AppImage release instead. That warning is worth taking literally: the AppImage is the fallback when the packaging path fails.

Windows users can install from the Microsoft Store, or from the command line with winget or scoop. The README gives both commands.

winget install electerm.electerm

scoop bucket add dorado https://github.com/chawyehsu/dorado
scoop install dorado/electerm

There is also a global npm install, which is useful if you already manage Node tooling.

npm i -g electerm

For a first session, launch the app and create a bookmark for a host you already have access to, supplying either a password or a public key. If you want to skip installation entirely, the README links an online demo at demo.electerm.org and a hosted instance at cloud.electerm.org. Upgrades follow the same channels: the README says a notification appears after you restart electerm when a new version is out, and npm users simply rerun npm i -g electerm.

Where electerm is the wrong tool

The honest limitation is the one the README implies by omission. electerm is an Electron application, and the README makes no claims about rendering performance, startup time or memory use. If your work is dominated by large log streams, wide terminal output at high refresh rates, or dozens of simultaneous sessions, an Electron renderer is not the architecture you would choose. Terminal emulators built on native GPU rendering exist precisely for that workload, and electerm does not compete there.

The protocol breadth is also a maintenance surface. SFTP, FTP, telnet, serialport, RDP, VNC and Spice are very different transports, and the README does not describe how mature each one is. RDP and VNC in particular are noted only as supported, with no statement about which features or encodings are implemented. Treat any non-SSH protocol as something to verify against your own targets rather than something the documentation guarantees.

Sync is another place where the documentation stops short. The README lists gist, WebDAV, custom server and electerm cloud as destinations, but it does not describe how conflicts are resolved when two machines edit the same bookmark set. If you sync from a laptop and a workstation, you are trusting behaviour the README does not spell out.

Finally, the platform list cuts both ways. Supporting Windows 7, Ubuntu 18.04 and glibc 2.17 constrains the Electron and Chromium versions the project can adopt. That is the cost of the reach, and it is a real one.

electerm alternatives and how they differ

The most direct alternative in search interest is Tabby, another Electron-based terminal. The difference is scope. Tabby is built around a terminal with a plugin system and a strong emphasis on shell integration and appearance; electerm's README instead emphasises protocol coverage, listing RDP, VNC, Spice, FTP and serialport alongside SSH. If you want a terminal you can extend, Tabby's plugin model is the closer fit. If you want one window that also opens a remote desktop, electerm covers ground Tabby does not advertise.

WezTerm is the opposite trade-off. It is a terminal emulator with its own configuration and multiplexing model, not a file manager or a remote desktop client, and it is not distributed for Android or HarmonyOS. Choosing WezTerm means giving up the SFTP panel and the graphical protocols in exchange for a different terminal architecture.

WindTerm and Termius appear in the same searches. Termius is a commercial cross-platform SSH client with team features; electerm is MIT-licensed and self-contained, which is the meaningful difference if licensing or data residency matters to you. WindTerm is a native-feeling terminal with SFTP and telnet support. The README does not compare electerm to any of these, so the distinction to hold onto is simply this: electerm's pitch is protocol breadth plus old-platform support, not terminal performance.

Maintenance, licence and upgrade cost

electerm is MIT-licensed, stated in both the README and package.json. That is a permissive licence: you can use, modify and redistribute the code, including in commercial settings, provided the copyright notice and permission notice are preserved. This is not legal advice, and if you plan to redistribute a modified build you should read the LICENSE file in the repository root rather than rely on the one-line label.

The project is not archived, and the last push was on 2026-08-28, the same day as the v5.3.15 release. Releases have been frequent: v5.3.0 on 2026-08-21, v5.3.5 on 2026-08-25, v5.3.15 on 2026-08-28. Note that package.json in the repository carries version 5.5.9, ahead of the listed releases, which is normal for a development branch but means the repository version and the latest published release will not always match.

Upgrade cost is low by design. The README describes an in-app upgrade notification after restart, a download-and-reinstall path, and npm i -g electerm for npm installs. Snap and other distribution systems may follow their own schedules, and the README notes this without promising anything. The hidden cost is the platform support commitment: if you depend on electerm running on Windows 7 or Ubuntu 18.04, you are depending on the project continuing to pin older toolchains, and that is a constraint the maintainers carry rather than you.

Editorial conclusion

Adopt electerm if you need one window that handles SSH, SFTP, telnet, serialport, RDP and VNC, or if you have to support Windows 7, Ubuntu 18.04, UOS or Kylin machines where newer Electron clients will not start. Do not adopt it if your work depends on a GPU-accelerated terminal, because electerm is an Electron app and the README makes no performance claims. Before rolling it out, verify that your distribution installs from the deb or rpm repository at repos.electerm.org, and test the sync target you intend to use, since the README lists several backends but does not document conflict resolution between them.
