Building in the
open.
We publish what we build, fix the bugs we find upstream instead of patching them in private, and pay the projects we depend on. The commitments below are specific enough to hold us to.
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
PSFSystems language for our high-performance runtimes
MIT/Apache-2.0Powers our gateway, blockchain, and infra tooling
BSD-3-ClauseThe backbone of our developer SDKs and web apps
Apache-2.0Powering every UI we ship
MITEvery hanzo.ai product is built on Next.js
MITThe database underlying all our stateful services
PostgreSQL LicenseFast caching and pub/sub throughout our platform
BSD-3-ClauseFoundation of our ML training and inference
BSD-3-ClauseOrchestrates every workload in production
Apache-2.0Containers make our MCP tools portable
Apache-2.0Observability across every service
Apache-2.0Our 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.
Earn from Open Source
We dedicate up to 5% of all compute costs to open source — distributed transparently based on verified Software Bills of Materials (SBOMs).
Connect Your Git
Sign in with GitHub or GitLab to verify your contributions across Hanzo repos and the upstream projects we depend on.
Connect Your Wallet
Link a wallet on any major chain (Ethereum, Solana, Polygon, etc.) or choose direct USD payout.
SBOM Verification
We trace every OSS dependency running in production and match it to contributors via Software Bills of Materials.
Transparent Payouts
Earn proportional to your code's actual usage. All distributions are public and auditable on-chain.
If your code powers Hanzo infrastructure, we want to pay you. Connect your git credentials to claim your share.
Up to 5% of compute goes back to the OSS authors
who made it possible
Every Hanzo deployment tracks software dependencies via SBOM. When your code powers compute on Hanzo, the authors get paid — automatically. Connect your GitHub, verify your contributions, pick a wallet.

Payouts based on SBOM attribution, contribution weight, and compute hours
Fully transparent payouts
All payouts are public. Every project, every contributor, every amount. Communities can vote to customize their split — for example, 10% to founder, 5% to maintainers, 85% to all contributors.

Contribute & Earn
We welcome contributions of all kinds — code, documentation, bug reports, and feature requests. Every contribution earns a share of compute revenue through our OSS Revenue Sharing program.
