Meta becomes gold member of Kotlin Foundation
Meta has joined the Kotlin Foundation as a gold member, formalizing the company's long-running investment in Kotlin across its Android organization. The move gives Meta a seat among the foundation's governing members and ties its internal Kotlin work more directly to the wider ecosystem.
The company's relationship with Kotlin is not new. Meta engineers have spent years migrating an Android codebase measured in tens of millions of lines from Java to Kotlin. That effort is driven in large part by an internal tool called Kotlinator, which automates conversion work while trying to keep the output idiomatic and compatible with Meta's internal frameworks. Meta has also participated in the enterprise Java-to-Kotlin working group, sharing lessons from that migration with other large-scale adopters.
Outside the migration itself, Meta has published Kotlin and Android build toolchain work through Buck2, its open source build system. The stated goal there is to give developers better tooling and practices for improving build speed and scalability at size.
What membership means
As part of the Kotlin Foundation, Meta will contribute to the grants program, which funds open source library authors and supports student and developer projects. The company frames the membership as part of a broader push to help Kotlin grow beyond any single platform and to keep the language's ecosystem healthy and collaborative.
Meta's open source output remains publicly available through its usual channels, including the Meta Open Source site and its social media accounts on Facebook, Instagram, Threads, X, and LinkedIn.
