Zellij
Low Trafficzellij.dev
Overview
Zellij is a free, open-source terminal multiplexer and workspace tool written in Rust, designed as a modern alternative to tmux and screen. It bundles a rich feature set out of the box including a plugin system, floating panes, and session management. The core team also offers a paid hosted session-sharing service currently in beta.
By the Numbers
Founders
Aram Drevekenin is a software developer who created Zellij as an open-source project, building it primarily in Rust. He has led the project from its initial release to a widely adopted terminal workspace tool.
Zellij was built in Rust partly as a learning exercise in the language, and grew organically into one of the most-starred terminal multiplexer projects on GitHub.

Competitors
The de-facto standard terminal multiplexer; older, more widely known, but less beginner-friendly and lacks a built-in plugin system
One of the original terminal multiplexers; very mature but largely considered legacy with minimal active development
A GPU-accelerated terminal emulator with multiplexing built in, targeting a different layer of the stack
Adjacent developer productivity tools in the terminal space; not direct competitors but compete for developer attention and config time

How They're Doing
Zellij has a strong and growing open-source community with over 20,000 GitHub stars and consistent contributor activity. The project is in active development with frequent releases adding new features like floating panes, plugin support, and session management. The team is now exploring monetization via a hosted session-sharing beta service.
●Launched a paid hosted session-sharing service currently in beta
●Maintained active release cadence with regular feature updates throughout 2023-2024
Prognosis
Zellij is well-positioned to capture developer mindshare as Rust-native tooling becomes more mainstream and developers seek modern tmux alternatives. The hosted session-sharing service represents a nascent but promising monetization path. Long-term sustainability depends on converting open-source users to paying customers.
●Growing demand for modern, user-friendly terminal tooling among developers
●Rust ecosystem momentum attracting contributors and users
●Session sharing and remote collaboration features could appeal to enterprise teams
●Difficult to monetize open-source developer tools at scale
●Competing against deeply entrenched tools like tmux that have decades of user habit
●Small core team limits development velocity and long-term maintenance capacity

Fun Facts
- 01Zellij means 'mosaic' in Arabic and Moroccan craftsmanship tradition, reflecting its tiled pane interface
- 02Zellij was built in Rust partly as the author's way to deeply learn the language, and became one of the most prominent Rust CLI tools
- 03The project can be launched instantly with a one-liner curl script, requiring zero installation — a deliberate onboarding design choice
- 04Zellij's plugin system uses WebAssembly, meaning plugins can be written in any language that compiles to WASM
