What is Rivet?
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.
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.
Rivet vs Zellij: editorial side-by-side
Rivet
7.5DEVOPS
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
◆ Current state
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.
◆ Where it's heading
Rivet keeps turning its S3-backed storage engine into features for agent workloads. Copy-on-write forking follows from the 3.0 storage design and gives agents a cheap way to branch a session, try something and discard it. The SDK and auth work of the past two months points to Rivet positioning actors as the runtime for agent backends.
◆ Prediction
Forking is likely to show up next in agentOS and the Pi integrations as a way to branch agent runs; the entries do not say when 3.0 leaves preview.
Zellij
3.8DEVOPS
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.
