history
Project history and usage
Kiesel is an experimental JavaScript engine written in Zig. It provides a custom bytecode virtual machine and runtime, plus a command-line REPL and file interpreter.
Project history
Linus Groh began Kiesel as a from-scratch project for learning Zig, with the longer-term aim of following current ECMAScript standards. The official repository was created on Codeberg in July 2023.
The implementation draws stylistic influence from SerenityOS and Ladybird's LibJS, particularly its close-to-spec approach. The project describes itself as early-stage and combines mostly Zig code with selected components for garbage collection, regular expressions, internationalization, and Temporal.
Adoption history
Kiesel publishes versioned releases and main-branch builds, tracks conformance through Test262, and is packaged by Alpine Linux, Homebrew, and Nix according to the supplied package metadata. Official releases 0.2.0 and 0.3.0 were published in 2026.
How it is used
The `kiesel` executable opens a REPL when run interactively, evaluates JavaScript files, or executes source passed with `--command`. Diagnostic options can print the parsed AST, bytecode, or intermediate representation, while embedding in other projects remains an explicit goal.
Why package nerds care
Kiesel is of interest as a young ECMAScript implementation built around Zig and a custom bytecode VM rather than an established browser engine. Its Test262 tracking, embeddability goal, and availability in several system package collections make implementation progress easy to follow and test.
Timeline
- 2023: The official Codeberg repository was created on July 2.
- 2026: Kiesel 0.2.0 was released on May 11.
