Zellij vs Aiven
A side-by-side editorial comparison of Zellij and Aiven — release velocity, themes, recent moves, and the top alternatives to consider.
Zellij vs Aiven: at a glance
What is Zellij?
Zellij is now a desktop terminal too, not just a multiplexer inside one.
Zellij 0.46.0 adds a desktop terminal app: `zellij terminal` opens Zellij as its own window on Linux, macOS and Windows, and those sessions are the same as the multiplexer's and can be shared. The multiplexer still runs inside other terminals unchanged. The release follows 0.45's nested sessions, Kitty graphics and prompt-aware scrollback, and 0.44's native Windows support. The single maintainer says venture-funded firms are moving into the space and asks for recurring donations.
What is Aiven?
Aiven moves Grafana to 13 and gives Runtime apps custom domains.
Aiven's November releases mix pricing changes with plumbing between its own services. The MySQL free tier stops on 21 December, bring-your-own-key encryption is included at no extra cost, and a change-data-capture integration now copies PostgreSQL tables into ClickHouse in limited availability. On 12 November Grafana 13.2 became available alongside 12.4, without Git Sync or the Synthetic Monitoring app, and Aiven Runtime applications gained custom domains and readable URLs.

Zellij

Zellij is now a desktop terminal too, not just a multiplexer inside one.
◆ Current state
Zellij 0.46.0 adds a desktop terminal app: `zellij terminal` opens Zellij as its own window on Linux, macOS and Windows, and those sessions are the same as the multiplexer's and can be shared. The multiplexer still runs inside other terminals unchanged. The release follows 0.45's nested sessions, Kitty graphics and prompt-aware scrollback, and 0.44's native Windows support. The single maintainer says venture-funded firms are moving into the space and asks for recurring donations.
◆ Where it's heading
Each release has widened where Zellij runs: a browser client in 0.43, Windows in 0.44, and now its own window. Owning the terminal window means it no longer depends on the host terminal for graphics, notifications and escape-sequence support.
◆ Prediction
Expect patch releases fixing desktop-terminal issues on specific platforms, as 0.45.1 did for 0.45.0; the entry flags breaking changes for plugin developers, so plugin updates are likely to follow.
Aiven
6.3DEVOPS
Aiven moves Grafana to 13 and gives Runtime apps custom domains.
◆ Current state
Aiven's November releases mix pricing changes with plumbing between its own services. The MySQL free tier stops on 21 December, bring-your-own-key encryption is included at no extra cost, and a change-data-capture integration now copies PostgreSQL tables into ClickHouse in limited availability. On 12 November Grafana 13.2 became available alongside 12.4, without Git Sync or the Synthetic Monitoring app, and Aiven Runtime applications gained custom domains and readable URLs.
◆ Where it's heading
Aiven is filling out the layer around its databases: logs, access control, encryption, dashboards and now an application runtime with its own domains. Each release is small, but together they make it easier to keep both data and the apps that use it on Aiven.
◆ Prediction
Expect more Aiven Runtime features that connect apps to Aiven's own databases, and a default-version switch to Grafana 13 once 12.4 nears end of support.
