A GoJS alternative without the per-application license
GoJS has the deepest built-in editor machinery in the commercial field and famously good vendor support. Teams reach for Grafloria when $3,995–$11,950 per application, per domain doesn't fit — or when they want full source and no license tracking across deployments.
When to stay with GoJS
You need an enterprise vendor relationship, its unmatched breadth of built-in diagram types, and licensing per application is fine for your model. It has earned its reputation.
Why teams switch
| Grafloria | GoJS | |
|---|---|---|
| License / price | MIT — $0, unlimited apps, domains, developers | ≈ $3,995–$11,950, licensed per application + per domain |
| Source | Full source, no lock-in | Obfuscated distribution |
| Frameworks | React · Angular · Vue · web component, native bindings | Vanilla core; wrappers |
| Undo, routing, layouts, exports | Included | Included — this is the fair fight; GoJS is deep here |
| Collaboration | Per-property CRDT + presence + comments | DIY |
| Diagram-as-text | Mermaid-compatible import/export with lossless sidecar | — |
Where GoJS is honestly ahead: sheer breadth of prebuilt diagram classes and two decades of
edge cases. Where we compete: the editor features most apps actually use, at the price of an
npm install, with the live demo gallery as the proof — every demo doubles as a CI test:
grafloria.com/demos.
How the concepts map
| GoJS | Grafloria |
|---|---|
nodeTemplate of GraphObjects | your framework's own templates/components as nodes — HTML and CSS, not a scene-graph DSL |
Model + TwoWay bindings | plain arrays with two-way bindings ([(nodes)] in Angular, hooks in React) |
Groups + placeholder | containers with live drag-adoption — demo |
AvoidsNodes routing | obstacle-avoiding router, on by default for routed edges |
| License key per domain | MIT — no key, no watermark, no per-app fee |
