About licensepicker

A free open-source license chooser and dependency license-compatibility checker — all in your browser.

Picking a license freezes a lot of people: MIT or Apache? Does GPL “infect” my project? The bigger trap comes later, when a dependency you added quietly carries a license that’s incompatible with your own. licensepicker handles both ends: a four-question wizard recommends a license (with full text and the canonical SPDX id), and a checker reads your package.json or requirements.txt, resolves each dependency’s license from the public npm or PyPI registry, and flags conflicts against your chosen license.

It’s built for open-source maintainers and indie developers shipping npm and PyPI packages. The recommendation logic, license texts, and compatibility matrix run as pure functions in your browser; only the per-dependency registry lookups touch the network, and your manifest is never uploaded to us.

This is informational guidance, not legal advice. License compatibility can depend on how code is combined and distributed — confirm important decisions with a qualified professional.
