The short version

Each has a real cost: Fig shut down on 1 September 2024. Amazon acquired Fig in August 2023 and folded it into Amazon Q Developer, which now carries the terminal autocomplete; K3s the SQLite default is single-server only; highly available control planes need etcd or an external datastore, which removes much of the simplicity

Fig

Shut down on 1 September 2024. Amazon acquired Fig in August 2023 and folded it into Amazon Q Developer, which now carries the terminal autocomplete
The standalone desktop app is no longer available or supported
The completion specs remain open source on GitHub, but the product that consumed them is gone

K3s

The SQLite default is single-server only; highly available control planes need etcd or an external datastore, which removes much of the simplicity
Bundled components such as Traefik are opinionated defaults that larger teams often strip out and replace
Removed in-tree cloud provider integrations mean cloud-specific features need external controllers
Aimed at small and edge clusters, so very large deployments are better served by a standard distribution

Answered from the vendors’ own pages

K3s: Is K3s free?

Yes. K3s is open source with no licence fee. SUSE sells commercial support around Rancher separately.

K3s: Is K3s real Kubernetes?

Yes. It is CNCF-certified conformant, so standard manifests, kubectl and Helm charts work without modification.

K3s: Why is K3s smaller than Kubernetes?

It strips legacy, alpha and in-tree cloud provider code, packages everything as one binary, and defaults to SQLite instead of etcd.

K3s: Can K3s run in production?

Yes, and it does, particularly at the edge and for small clusters. For a highly available control plane you need to move off the SQLite default to etcd or an external datastore.
