Show HN: ThorVG 1.0 – Fast vector rendering with Lottie and GPU back ends
hermet Monday, February 02, 2026
Hi HN.
We’ve just released ThorVG 1.0, which marks a maturity milestone for the engine. Earlier versions focused on feature growth; this release emphasizes stability, backend parity, and consistent rendering behavior across platforms, including the web.
ThorVG is an open-source, embeddable C++ 2D vector graphics engine used for SVG-style graphics and Lottie.
[What 1.0 means]
This version is less about new features and more about engine readiness: - Improved rendering performance and engine optimizations
- Improved blending accuracy and text layout behavior
- WebGL backend now officially supported
- WebGPU backend promoted to production-ready status
- Introduced a lightweight WebCanvas path for browser environments
- Broader Lottie spec coverage for more complex animations
- New interaction support including bounding box queries and hit detection
- More predictable API behavior for integration
ThorVG is intended as a small rendering layer for engines, UI systems, embedded devices, and tools where size and deterministic performance matter.
