What is K9s?

K9s keeps up a brisk 0.50.x patch cadence driven by community fixes.

K9s, the terminal UI for Kubernetes, is in a high-frequency patch cadence — nine point releases from 0.50.10 to 0.50.18, several shipping the same day. The notes are community-thanks boilerplate rather than itemized changelogs.

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.

K9s vs Rivet: editorial side-by-side

K
K9s
DEVOPS
0.0

K9s keeps up a brisk 0.50.x patch cadence driven by community fixes.

◆ Current state

K9s, the terminal UI for Kubernetes, is in a high-frequency patch cadence — nine point releases from 0.50.10 to 0.50.18, several shipping the same day. The notes are community-thanks boilerplate rather than itemized changelogs.

◆ Where it's heading

Steady maintenance on the 0.50 line, with rapid bug-fix turnaround driven by community issue reports rather than new feature pushes.

◆ Prediction

Expect continued 0.50.x patch releases at this cadence; no new capability direction is visible in these notes.

R
Rivet
DEVOPS
7.5

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.
