The Linux Foundation Projects
Skip to main content


Stages – Definitions & Expectations

Every Foundation project has an associated maturity level, as voted on under the approved Project Lifecycle Document (PLD) process. Proposed Foundation projects should state their preferred maturity level. Projects of all maturities have access to Foundation resources.

All Foundation projects may attend TAC meetings and contribute work regardless of their stage.

Impact Stage

The Impact Stage is for projects on a self-sustaining cycle of development, maintenance, and long-term support. Impact Stage projects are widely used in production environments with a significant number of public use cases. Moreover they have broad, well-established communities with a number of diverse contributors.

Growth Stage

The Growth Stage is for projects that are interested in reaching the Impact Stage, and have identified a growth plan for doing so. The Growth Stage is meant to harbor projects still working on their product or service and are working towards supporting adopters at scale using the product or service (examples: releasing a bug fix, having to provide guidance on upgrades, addressing a security issue, etc.).

At Large Stage

At Large projects are open-source efforts which the TAC believes are, or have the potential to be, important to the edge ecosystem as a whole. They are typically early-stage efforts looking to add capabilities to the LF Edge open edge platform as a whole in exchange for community support.
