Flower Labs

Open source activity

As of Nov 14, 2026

Open source is the core of Flower Labs' business rather than a side project. Its main public repository, flwrlabs/flower, holds the Flower federated-learning framework under the permissive Apache 2.0 license, which lets companies use and modify it commercially for free. With about 7,200 GitHub stars, roughly 1,200 forks and nearly 6,000 code changes, it has a sizable following for a specialist tool, and it is updated often: version 1.43 shipped on November 4, 2026, the 72nd release on the Python package index. The company says more than 180 people have contributed and that over 2,500 projects build on it.

Beyond that flagship, the GitHub footprint is thin: the flwrlabs account lists only two other small repositories, and an older Flower Labs account, adap, now shows none. Its models live on Hugging Face instead, where it publishes the open-weight Lizzy 7B along with 23 datasets. Its most commercially important model, Endeavor, is not open: Flower distributes it privately under license, so the open-source footprint shows the reach of its free framework, not the quality of the product it hopes to sell.
