Introducing the cli.dev Ecosystem

Over the last few months, I have been working on several projects that share a common thread but have lived across different repositories and domains. Today, I am giving them a shared home: cli.dev.

The domain has a little history. cli.dev was the second-choice domain for Hydra. Facebook obtained it before it managed to obtain hydra.cc; once it did, Hydra moved and cli.dev spent the following years as a derelict redirect. I am now giving it a new role.

The cli.dev ecosystem brings together tools, products, and experiments for building, deploying, and operating software. It currently includes Hydra, OmegaConf, Arbiter, Reploy, and OmegaFlow.

This is the launch of the ecosystem, not a simultaneous launch of all its projects. Several are still under active development, and not all are ready for general use yet.

This is an umbrella, not a monorepo or a new name imposed on every project. Each project keeps its own identity, website, documentation, repository, and release lifecycle. cli.dev provides a directory and a little shared context for understanding how the projects relate.

Some of them are mature and widely used. Hydra and OmegaConf have been around for years. Others are newer and still taking shape:

• Arbiter is a capability firewall between AI agents and external services.
• Reploy is a deployment lifecycle tool for staging, testing, installing, and operating services from portable blueprints.
• OmegaFlow turns scripted terminal workflows into repeatable videos.

The umbrella is intentionally broader than open source. Many of these projects are open source, and open source remains important to me, but cli.dev is not a license category. It is a home for related work. Future additions may be open source tools, hosted products, or experiments that do not fit neatly into either category.

For me, cli.dev is a way to make the larger body of work visible without pretending that every project is the same kind of thing. I expect the directory to evolve as the projects mature and as new ones become ready to share.
