kubernetes vs wasm3
kubernetes has 127,843 GitHub stars, 44,692 forks, 3,072 open issues and last shipped today. wasm3 has 8,028 stars, 539 forks, 18 open issues and last shipped yesterday. kubernetes leads on adoption by 1,492% (127,843 vs 8,028 stars). kubernetes is written in Go under Apache-2.0; wasm3 is written in C under MIT. kubernetes has attracted 35% as many forks as stars, wasm3 7%. kubernetes was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (containers), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.

pick kubernetes if
- You weight community size — 128K stars and counting
- You want the Apache-2.0 license terms
- Your stack matches Go
- You value the larger contributor base for long-term maintenance
pick wasm3 if
- You want the wasm3 feature set and don't need the biggest community
- You prefer the MIT license terms
- Your stack matches C
- You evaluated both and wasm3 fits your workflow better
About kubernetes
Kubernetes (K8s) is an open source, Apache 2.0 licensed system for managing containerized applications across multiple hosts, hosted by the Cloud Native Computing Foundation and aimed at teams who deploy, maintain and scale container packaged and microservices oriented workloads in production.

About wasm3
Wasm3 is a fast, MIT licensed WebAssembly interpreter written in C that runs across x86, ARM, RISC V, MIPS, Xtensa and other architectures — from ESP8266 microcontrollers and OpenWrt routers to browsers and Linux servers — and it is aimed at developers and embedded engineers who need to execute portable Wasm or WASI code where a full size runtime will not fit.
