Why Graxeon

Everything your knowledge base needs.
Nothing it doesn't.

Built for teams that care about structure, longevity, and true ownership of their data.

Schema-first
Define types with typed fields once in Studio. Every item is validated against the schema — no more loose, inconsistent data as collections grow.
KGL format
Plain text .kgl files — diff in git, read with any editor, parse with the open kgl-lang PyPI package. No proprietary format.
Share via Explorer
Invite teammates to browse or edit collections in Explorer. Role-based access: owners, editors, and read-only viewers.
Knowledge graph
Link items across collections. Navigate relationships visually and discover connections that a flat spreadsheet would never show.
Rich text authoring
Write Markdown with a live preview, powered by Monaco editor — the same engine as VS Code. Structured fields and prose, side by side.
Self-hosted & open source
One docker compose up and you're running. No account needed, no credit card, no phone home. Core is MIT-licensed and always will be.
How it works

Studio builds. Explorer shares. Files are yours.

Three concepts. One format connecting all of them.

Studio
01 — Design
Build your schema
Define types with typed fields. Studio validates every item — text, numbers, dates, rich text, files, and more — so structure is enforced, not hoped for.
Studio
02 — Populate
Fill your collection
Add nodes, write rich text, attach images and files, link related items. Every change writes directly to .kgl files — commit them, back them up.
Explorer
03 — Share
Invite your team
Owners and editors can update items; viewers get a clean read-only experience with full search. No Studio account needed to browse.
Always yours
04 — Own
Data in plain text
.kgl files live in MinIO or on disk. Export, migrate, open in a text editor. No lock-in. No asking permission to leave.
Data ownership

Your data. Plain text.
Yours forever.

Most knowledge tools are landlords — your data lives in their database, on their terms, until they raise prices or shut down. Graxeon is different: your knowledge lives in files that belong to you, readable without any special software.

Portable Open .kgl files with any text editor, any OS
Versionable Commit to git — full history, diffs, branching
Open spec kgl-lang parser on PyPI — write your own tools
