About LUCA

The philosophy behind true software freedom

Philosophy

The LUCA Free License (Liberty Unrestricted for Creative Autonomy) was born from a simple belief: software should be truly free.

Not free as in "free beer" or free with a thousand strings attached. Free as in "do whatever the fuck you want with it."

The Problem with Existing Licenses

Modern software licensing has become unnecessarily complex

MIT/BSD

Great licenses, but require attribution in every distribution. This can be burdensome for developers.

GPL

Forces copyleft, restricting how you can use the code. Not ideal for commercial integration.

Apache 2.0

Comes with pages of legal text and complex patent clauses. Excellent but verbose.

WTFPL

Simple and radical, but legally questionable in some jurisdictions. Lacks proper disclaimers.

Each has its place, but sometimes you just want to say: "Here's my code. Use it. I don't care how. Good luck."

The LUCA Solution

1. Maximum Freedom

DO WHAT THE FUCK YOU WANT TO

The core principle. No restrictions, no limitations, no strings attached.

2. Legal Protection

No warranty - we're not responsible for your use

Clear warranty disclaimer protects developers from liability.

3. Severability

If parts fail, the rest stands

Ensures the license remains valid across different jurisdictions.

Design Principles

1. Maximum Freedom

We believe that once you release code to the world, you should release it fully. No strings, no conditions, no complex requirements. True freedom means the recipient can do anything they want with the code.

2. Legal Clarity

While keeping the spirit of simplicity, LUCA includes necessary legal protections:

  • Clear warranty disclaimer
  • Severability clause (if one part fails, the rest stands)
  • Explicit statement of permissions

3. Universal Applicability

LUCA is designed to work across jurisdictions. The severability clause ensures that even if a court strikes down part of the license, the core principle remains: do what you want.

4. Developer-Friendly

We wrote LUCA for developers, not lawyers. You shouldn't need a law degree to understand your rights and obligations.

History

LUCA was created in February 2026 as an evolution of the permissive license philosophy. Inspired by licenses like WTFPL but designed with modern legal considerations in mind, LUCA aims to be both maximally permissive and legally sound.

The Name

L - Liberty

True freedom to use, modify, and distribute

U - Unrestricted

No artificial limitations on your rights

C - Creative

Empowering developers to create without barriers

A - Autonomy

Full control over your use of the software

The name also references LUCA (Last Universal Common Ancestor) in biology - the ancestor of all life. Similarly, this license aims to be a foundation that can evolve into whatever you need it to be.

Who Should Use LUCA?

Perfect For:

Open Source Enthusiasts

Who believe in true freedom

Educators

Sharing code without licensing hassles

Hackers & Tinkerers

Releasing tools and experiments

Businesses

Wanting to donate code without obligations

Anyone

Who just wants to share code without bureaucracy

Maybe Not For:

Attribution Requirements

Projects requiring attribution for recognition

Copyleft Needs

Projects wanting to ensure modifications stay open (use GPL instead)

Regulated Industries

Projects in heavily regulated industries (might need more specific warranties)

Legal Departments

Organizations with strict legal departments (they might prefer Apache 2.0)

Legal Standing

LUCA is designed to be legally sound

Warranty Disclaimer

Clear and comprehensive disclaimer of all warranties

Severability

Ensures the license remains valid even if parts are struck down

Explicit Grant

Clear grant of permissions to use, modify, and distribute

Self-Modifiable

The license itself can be modified and redistributed

Legal Review: While we encourage you to review any license with your legal counsel, LUCA's simplicity makes it easier to understand and evaluate than many alternatives.

Inspiration

We stand on the shoulders of giants

WTFPL

For radical simplicity and the courage to say "do what you want"

MIT License

For clarity, acceptance, and establishing permissive licensing

Unlicense

For dedication to public domain and maximum freedom

BSD

For the permissive philosophy and developer-friendly approach

The Bottom Line

LUCA exists because sometimes you just want to release code into the world and say "have fun." No drama, no tracking, no requirements. Just pure, unadulterated freedom.

DO WHAT THE FUCK YOU WANT TO.
