It's a bit like symfony/thanks, but it tries to tackle a bigger problem! The climate crisis.

Open Source can have positive impact on it. With Treeware every donation is a motivation to work on Open Source code.

The Treeware idea is great, but it's not very visible. This package tries to solve it.


Add this package as dependency to your package:

$ composer require treeware/plant

Add an extra attribute to your package composer.json that contains at least an empty treeware object:

    "extra": {
        "treeware": {}

Or use this handy shortcut:

composer config extra.treeware --json {}

To change the default output, add your own teaser and priceGroup properties:

    "extra": {
        "treeware": {
            "teaser": [
              "Your message to the consumers of your package to convince them.",
              "Multiple lines are possible, but not more than 3 lines and 200 characters."
            "priceGroups": {
              "useful": 100,
              "important": 250,
              "critical": 500
