README
¶
Crossplane is a framework for building cloud native control planes without needing to write code. It has a highly extensible backend that enables you to build a control plane that can orchestrate applications and infrastructure no matter where they run, and a highly configurable frontend that puts you in control of the schema of the declarative API it offers.
Crossplane is a Cloud Native Computing Foundation project.
Get Started
Crossplane's Get Started Docs cover install and cloud provider quickstarts.

Roadmap
The public roadmap for Crossplane is published as a GitHub project board. Issues added to the roadmap have been triaged and identified as valuable to the community, and therefore a priority for the project that we expect to invest in.
The maintainer team regularly triages requests from the community to identify features and issues of suitable scope and impact to include in this roadmap. The community is encouraged to show their support for potential roadmap issues by adding a 👍 reaction, leaving descriptive comments, and attending the regular community meetings to discuss their requirements and use cases.
The maintainer team updates the roadmap on an as needed basis, in response to demand, priority, and available resources. The public roadmap can be updated at any time.
Milestones assigned to any issues in the roadmap are intended to give a sense of overall priority and the expected order of delivery. They should be considered approximate estimations and are not a strict commitment to a specific delivery timeline.
