About


Hi, my name is Lars and I ❤️ open source!

Over the years the open source community has helped me tremendously to grow as a developer, and I'm using this knowledge and experience in my professional work. It was only natural for me to give something back to the community. I enjoy working on open source projects, and I'm proud to say some of my projects are used by quite a few people and companies.

Selected works

- Knip — Find unused files, dependencies and exports in JS & TS projects
- remove-unused-vars — Remove more unused variables
- unbarrelify — Barrel file removal tool for JS & TS projects (ESM-only)
- unbash — Fastest 0-deps bash parser written in TypeScript
- Venz — Create charts from numbers
- ANSI.tools — Analyze & look up escape sequences, fast parser available separately

Sponsorships allow me to improve projects like Knip and help out fellow developers. I prefer sponsorships coming from companies. Monthly sponsorships of people or companies using Knip will be featured on the Knip sponsors page.

Have a wonderful day! Take care ❤️
