MIT License
The most permissive open source license. Use the code for anything as long as you preserve the copyright notice.
The MIT License is the simplest and most permissive widely-used open source license. It permits commercial use, modification, distribution, sublicensing, and private use — with two requirements: include the copyright notice and the permission notice in copies. There's no warranty.
It's about 200 words long. If you want maximum adoption with minimum friction, MIT is the default choice. JavaScript ecosystem heavily favors MIT — React, Vue, Express, Next.js are all MIT.
Practical implications: anyone can take MIT code, modify it, and ship it inside a closed-source product without releasing their changes. This trade-off (max freedom for users, max risk of "extraction" by cloud providers) is why some projects prefer copyleft (AGPL) or source-available (BSL).
