LemmaBase
A public registry for rules
LemmaBase is where teams write rule specs, publish snapshots, and make work discoverable when they are ready to share. A repository holds your files; a publication is the version you put live.
Repositories can be public or private. Public ones show up in search so anyone can find your handle, open the repository, and read what you have published.
Write and publish
Create a repository under your personal handle or an organization. Edit rule files in the browser, then publish when a version is ready. Each new publication supersedes the previous one for that repository, so there is always a clear current snapshot for readers and for your own team.
People with access can browse publication history in the editor and see how a repository evolved over time.
Try before you publish
The editor includes a Consult view to run specs against sample input while you are still drafting. Check outcomes before anything goes live, without leaving the repository.
Discover what is public
Registry search covers public users, public repositories, and published spec names. Open a repository in the browser to read its current published workspace. Search matches names and metadata—not full-text inside every rule.
Who can see your work
Repositories can be private, visible to an organization, or public. Only public repositories appear in search. Private and organization-scoped repos stay off the public index; access follows your account and membership.
Built for shared rule logic
LemmaBase suits teams that want rules written down, reviewed, and found again: policy, pricing, eligibility, operations, compliance—logic that should not live only inside application code or informal documents.
Users get stable handles; readers get one registry to search and open specs in the browser. When a repository is public, its published workspace can be referenced from other specs in the wider Lemma ecosystem without copying files by hand.
