Open Source First

Building in the
open.

What Hanzo is built on

The projects our platform actually runs on, each with its licence and the people who maintain it.

The language powering our ML/AI stack

PSF

Systems language for our high-performance runtimes

MIT/Apache-2.0

Powers our gateway, blockchain, and infra tooling

BSD-3-Clause

The backbone of our developer SDKs and web apps

Apache-2.0

Powering every UI we ship

MIT

Every hanzo.ai product is built on Next.js

MIT

The database underlying all our stateful services

PostgreSQL License

Fast caching and pub/sub throughout our platform

BSD-3-Clause

Foundation of our ML training and inference

BSD-3-Clause

Orchestrates every workload in production

Apache-2.0

Apache-2.0

Our Stewardship Commitments

We hold ourselves to explicit, public commitments — not vague marketing language.

We ship open source first

Every tool we build for ourselves gets published. If it's useful to us, it belongs to the community. No internal-only forks.

We contribute upstream

When we find bugs or missing features in projects we depend on, we fix them upstream — not in private patches.

We never lock in what we open

Anything published under MIT or Apache-2.0 stays that way. We will never relicense open repos to extract commercial value.

We credit our foundations

Our platform is built on hundreds of open-source projects. We acknowledge, link to, and financially support the communities and maintainers who make this possible.

We fund what we depend on

Through GitHub Sponsors, Open Collective, and direct partnerships, we invest back into the projects that power Hanzo.

We welcome all contributors

Good code can come from anywhere. We maintain a contributor-friendly CONTRIBUTING.md, respond to PRs within 48 hours on active repos, and recognize every contributor.

Open source royalty

20% to the author of the code that runs

Verify that you own a repository, and every org that deploys a project built from it pays you 20% of its metered spend, accrued each period.

What we publish

Read from GitHub by every build: the year of commits, the languages and the repositories of each ecosystem, then every organization.
