The honest comparison, with the rows we lose.
The graph visualization market divides into commercial SDKs with strong support, and open-source libraries with broad adoption and no support. We are trying to be a third thing: commercial-grade capability with a free edition you may use in commercial apps. A comparison table where one vendor wins every row is read as marketing and discarded, so the rows where the established vendors are ahead are on this page too.

Against graph visualization tools.
Capability | Tessera Viz | Commercial graph SDKs | Open-source libraries |
|---|---|---|---|
Graph rendering | SVG, Canvas, WebGL | Canvas / WebGL | Canvas / WebGL |
Layouts | 20 | 10–30 depending on vendor | 5–15 |

Timeline in the same library | Yes | Separate product | No |
Map in the same library | Yes | Separate product or add-on | No |
Data grid in the same library | Yes | No | No |
Third-party runtime dependencies | None | Varies | Several to many |
Air-gapped deployment | Documented, supported | Possible; varies by vendor | Do it yourself |
Vector basemaps | Own renderer, no dependency | Via a mapping library — a dependency | Do it yourself |
3D | Yes; WebXR on Enterprise | Some vendors | Some |
React / Vue / Svelte / Angular | All four, plus Web Components | React commonly; others vary | Community wrappers |
Accessibility: keyboard navigation | Yes | Varies | Rare |
Accessibility: screen reader | Yes, on the SVG renderer | Varies | Rare |
Maturity and references | New. No public references yet | Established, many named customers | Very large user bases |
Licensing | Free edition for commercial apps (not open source); paid tiers per application | Commercial | Open source |

Where they are ahead.
01
Maturity
The established vendors have been shipping for over a decade and have named customers in banks and government agencies. We do not, yet. If a reference customer in your exact sector is a requirement, we are not the safe choice today.
02
Professional services
Several offer consultants who will build your application with you. We do not offer that yet.
03
Specific depth
Some vendors have specialised capabilities — particular routing algorithms, particular compliance certifications — that we have not built. Ask us directly and we will tell you straight whether we have it.

Linked to a graph, map and timeline | Yes | No |
Same theme tokens as your charts | Yes | No |

Where they are ahead, on grids.
01
A decade of edge cases
A mature grid vendor has ten years of them behind it and an enormous community. If your application is primarily a grid, that matters more than anything in our column — buy the specialist.
02
Where ours is strongest
When the table is one of several linked views of connected data. That is the case we built it for: the grid scrolls to the node you clicked because it is the same selection, not a second one your code keeps aligned.

About this comparison.

Reviewed quarterly
A stale comparison is a legal and reputational problem, not merely an inaccurate one. If you are reading this more than three months after the date above, ask us and we will re-verify before you decide.

Head-to-head, one competitor at a time.

What switching really takes.
01
A straightforward graph view
Typically days. The concepts map closely: nodes and links are nodes and links, a layout is a layout, and the event you were listening for has an equivalent.
02
An application with heavy custom rendering
Typically weeks, and the custom drawing is where the time goes. The renderer is an interface, so bespoke rendering ports rather than being rewritten — but it does have to be ported.
03
A scoped assessment, free
We will look at what you have and tell you what it would take, including telling you if it is not worth doing. An honest no costs us one assessment; a bad migration costs both of us a year.
