The reference for licenses that say who, not just how

Where does your project sit?

Open source is one corner of a much bigger map. Here's the rest of it — read left to right for who may use it, bottom to top for how soon it opens up.

Grid lines are guidance, not data: the four bands name the territory, the three rows say already open · opens on a date · never opens. A dot's exact position is an argument, not a measurement.

Four bands, four questions

01

Open source

Can anyone use it, forever, no conditions?

MIT License, Apache License 2.0, GNU General Public License v3.0

02

Delayed open

Free today — on whose timeline does it open up?

Business Source License 1.1, Functional Source License 1.1 (MIT Future License)

03

Restricted

Free for almost everyone — except whom?

Elastic License 2.0, PolyForm Small Business License 1.0.0, Prosperity Public License 3.0.0

04

Proprietary

Is there a public grant at all?

All-rights-reserved / EULA — no public grant. Nothing to chart here; this is where "ask a lawyer" starts.
