Company

Line & Vertex Software Company LLC builds creative software and graphics tooling with one goal: make pro workflows feel fast, clear, and dependable.

Focus

Tools for creators and developers who care about craft and speed.

Approach

Performance-first foundations + practical UX decisions.

Philosophy

Ownership-friendly licensing and honest product direction.

What we build

Products with a clear point of view

Splineworks

Vector animation & drawing for professionals

A timeline-first workflow with precision tools and practical output — built to stay responsive on real projects.

vertexa-chart

WebGPU chart rendering + D3 overlays

An open-source charting library that uses WebGPU for high-throughput traces and D3 for axes, ticks, labels, and interaction layers.

How we build

Performance is a feature

We design around responsiveness: large projects, heavy scenes, and real datasets should stay smooth.

UX that respects attention

Tools should be discoverable and predictable — fewer traps, fewer modes, less UI noise.

Cross-platform by default

We aim for consistent behavior across macOS, Windows, and Linux — no “second-class” platform.

Open source where it makes sense

We publish libraries and components when it helps the ecosystem and keeps the core product focused.

Ownership-friendly licensing

Perpetual licensing for creative tools (with optional upgrades) keeps incentives aligned with users.

Honest roadmap

We’d rather ship fewer things well than promise everything — and we’ll tell you what’s in-progress.
