03 · Repositories
Twelve parts, twelve repositories.
04 · What isn’t open
The model stays ours.
The software is open. Lumbridge 1, the model we train and serve, is a paid service: you call it by the token, under an acceptable-use policy. You never need it to run Lumbridge; any OpenAI-compatible endpoint works, including one on your own GPU box.

Built on other people’s work.
None of this exists without the projects below. Third-party notices ship with each repository.

- We build onRustThe language most of the stack is written in.rust-lang.org
- We build onZed and GPUIThe interface library behind the App and Mail comes from the Zed editor.zed.dev
- We build onRatatuiThe terminal interface library behind the TUI and Notes.ratatui.rs
- We build onHerdrLumbridge Core, App and TUI began as forks of Herdr, an Apache-2.0 project. We have since taken them our own way and maintain them separately.herdr.dev
- We runNVIDIA Nemotron 3.5 BoltThe open model our own agents use day to day, in its official 2-bit build, served by Lumbridge Computer.huggingface.co
- We learned fromOmarchyProof that an opinionated setup on top of Linux can be a product people love. We like what they are doing and support it.omarchy.org
- We learned fromOrcaAn agent workspace we used before building our own. It showed us what running many agents at once should feel like.onorca.dev
Questions
Questions about the release.
Is this an OSI open-source license?
Yes. Apache-2.0, with nothing added or removed.
Can I see a gated repository now?
If you’re evaluating it for your team, yes. Contact us with what you’re building and we’ll add you.
Will every part stay open source?
The twelve parts on this page are the system we run, and they are what we are releasing. The model and its training data are not part of the release.
Do you accept contributions?
Yes, once a repository is open, through pull requests. Until then, tell us what you’d change.
Is there a paid version?
No paid edition of the software. We charge for Lumbridge 1 by the token, and for our time if you want us to install and run Lumbridge with you.
Does it collect telemetry?
No. Builds from source do not report usage or check in with us.
Where do I report a security problem?
Email security@lumbridgecorp.com. Please don’t open a public issue for it.
Who owns the name?
“Lumbridge” and the three-box mark are Lumbridge Corp trademarks. The license covers the code; please rename a fork you distribute.
Where do you post updates?
On the blog here and on X. X is our only social account; we don’t run a chat server.
Want in before a part opens?
Create an account, give us your GitHub username, and we add you to the repositories you need.
