Picking an open-source license is a one-line decision with multi-year consequences. MIT and ISC are permissive (do anything, just keep the notice). Apache 2.0 adds an explicit patent grant. GPL-3 is copyleft (derivatives must stay open). MPL 2.0 is file-level copyleft (changes to MPL files must stay open, but you can mix with closed code). The OSS License Picker shows all 8 popular licenses side-by-side with permissions / conditions / limitations (from the choosealicense.com vocabulary) and produces a ready-to-commit LICENSE file with your name and year substituted. Pure JavaScript, runs in your browser — no upload, no signup, no tracking. Licenses themselves are public domain text.
I want maximum adoption (MIT/Apache pattern): → MIT or Apache-2.0 I want patent protection (Apache 2.0 grants this): → Apache-2.0 I want copyleft (derivatives must stay open): → GPL-3.0 I want file-level copyleft (mix with proprietary OK): → MPL-2.0 I want the shortest license (older but valid): → ISC or BSD-2-Clause I want the BSD with no-endorsement clause: → BSD-3-Clause I want to release into the public domain: → Unlicense
