Kubeterm vs k9s
k9s is the terminal UI most Kubernetes engineers reach for, and it is genuinely excellent at what it does. Kubeterm is a graphical client. The honest comparison is less about which is better and more about which moment you are in.
| Kubeterm | k9s | |
|---|---|---|
| Interface | Graphical, desktop and mobile | Terminal UI, keyboard driven |
| Price | Free on desktop | Free, Apache 2.0 open source |
| Works over SSH / headless | No | Yes |
| Platforms | macOS, Windows, Linux, iOS, Android | Linux, macOS, Windows |
| Mobile app | Yes | No |
| AI assistant | Built in, bring your own key | None |
| Argo CD & Flux CD | Built in | Via custom plugins |
| Helm releases | Full lifecycle + Artifact Hub | Not part of the core README |
| Logs, shell, port forward | Yes | Yes |
| CRDs | Yes | Yes |
| Extensibility | No plugin API | Plugins, skins, custom aliases |
| Startup cost | Install an app | One binary, already in your shell |
The short version
If you are comfortable in a terminal, k9s is faster for almost everything you do dozens of times a day: jumping between resources, tailing a log, shelling into a pod. It also runs where a desktop app cannot — over SSH, on a jump host, on a machine with no graphical session at all.
Kubeterm is for the other half of the job: scanning a cluster you do not know well, reading a long YAML without a pager, comparing what Argo CD thinks is deployed against what is actually running, and getting a second opinion on a failing pod. And it is on your phone when the page comes in at the weekend.
Where k9s wins
- Speed for people who live in the shell. No window switching, no mouse. Once the key bindings are muscle memory, nothing graphical keeps up.
- Remote and headless access. A single binary that runs anywhere you can open a terminal, which matters when the only route to a cluster is through a bastion.
- Extensibility. Plugins, custom aliases, and skins let you bend k9s around your own workflows. Kubeterm has no plugin API.
- Open source. Apache 2.0, with a large community and a long history.
Where Kubeterm wins
- Reading, not just navigating. Colour-coded status across every resource type including CRDs, node and pod metrics, and inline YAML editing in a real editor rather than a terminal pager.
- AI that can see the cluster. Ask why a deployment is stuck and the assistant reads the manifest, recent events, and logs before answering.
- GitOps in one place. Helm releases, Argo CD applications, and Flux CD resources appear under a single Applications section, read straight from the cluster API.
- A phone in your pocket. The same workflows on iOS and Android. k9s has no mobile story.
How to choose
Keep k9s — genuinely. It costs nothing and it is the right tool for terminal work and remote access.
Add Kubeterm when you want a graphical view of an unfamiliar cluster, AI-assisted troubleshooting, GitOps visibility without plugins, or cluster access from your phone. They are complementary far more often than they are competing.
Common questions about Kubeterm and k9s
- Is Kubeterm a replacement for k9s?
- Not exactly. k9s lives in your terminal and is unbeatable when you are already on the command line or working over SSH. Kubeterm is a graphical client for reading cluster state quickly, editing YAML comfortably, and investigating failures with AI help. Most people who use both keep k9s for fast keyboard work and open Kubeterm when they want to see the whole picture.
- Is k9s free?
- Yes. k9s is open source under the Apache 2.0 licence and free to use. Kubeterm is free on macOS, Windows, and Linux, with no account required; the iOS and Android apps are a paid subscription.
- Can k9s run on a remote server without a desktop?
- Yes, and this is the clearest reason to keep it. k9s is a single binary that runs in any terminal, including over SSH on a bastion or a headless node. Kubeterm is a desktop and mobile application and cannot do that.
- Does k9s have an AI assistant?
- No. k9s has no built-in AI features. Kubeterm includes an AI chat that reads live cluster state — manifests, events, and logs — to explain why a workload is failing. You supply your own OpenAI, Anthropic, Gemini, or DeepSeek key, and the assistant is read-only until you widen its permissions.
