## 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.
- 2026: Kiesel 0.3.0 was released on July 17.

### Related projects

- LibJS influenced Kiesel's specification-oriented implementation style.
- Test262 is used to track Kiesel's ECMAScript conformance.

## Security Notes

No matching local secret-handling manifest was found for kiesel. Nucleus package metadata is still published here so future coverage has a stable package URL.
