Tessera Viz vs KeyLines.
KeyLines is a good product. If a graph is all you need and you want a decade of production history behind it, buy KeyLines — we will say so on a call. This page is for the team that needs a graph and a timeline and a dashboard and a table.

Who this page is for.
01
You already bought a graph SDK
And it works. Then the timeline arrived as a second product, the dashboard needed a charting library and the table needed a grid vendor.
02
Four of everything
Four licences, four theming systems, four renewal dates — and a file in your codebase whose only job is keeping four selections in step. That file has bugs. It always has bugs.

Where KeyLines is ahead.
01
Maturity
Over a decade of production use, with named customers in banks and government agencies. We have none, publicly. If a reference in your sector is a requirement, we are not the safe choice today.
02
Professional services
They have consultants who will build your application with you. We do not offer that.
03
Specific depth
Particular routing algorithms, particular certifications. Ask us directly and we will tell you straight whether we have it.

Keeping this current, and what switching takes.
01
Verified, and dated
Checked against the vendor's published information on 25 September 2026. This page is re-verified quarterly; if you are reading it more than three months after that date, ask us and we will check before you decide.
02
Migration
The concepts map closely: nodes are nodes, a layout is a layout, and the event you listen for has an equivalent. A straightforward graph view is typically days. Heavy custom rendering is weeks, and the custom drawing is where the time goes.
03
A free assessment
We will look at your case and tell you what it would take, including telling you not to bother. An honest no costs us one assessment; a bad migration costs us both a year.
