For anyone looking at this space: ThorVG is worth checking out.

Open-source vector engine with GPU backends (WebGPU, OpenGL), runs on microcontrollers to browsers. Now a Linux Foundation project.

(Disclosure: CTO at LottieFiles, we build and maintain ThorVG in-house, with community contributions from individuals and companies like Canva)

ThorVG might be worth a look - open source (MIT), ~150KB core, GPU backends (WebGPU, OpenGL).

We are using it as official dotLottie runtimes, now a Linux Foundation project. Handles SVG, Lottie, fonts, effects.

Re:Ask HN: Any example of successful vibe-coded product? on Tuesday December 30, 2025 @07:33PM (#46439978)
I built https://screenshot2charts.com, a tool that turns screenshots or CSV/JSON into editable charts. It solves the annoying problem of re-creating messy charts for reports and presentations, especially when all you have is a blurry screenshot of either a chart or some numbers.

From my experience, the biggest difference between vibe-coded projects that go somewhere and the ones that don’t isn’t code quality, it’s whether the builder keeps talking to users after the first version. The “vibe” gets you to ship, but iteration discipline is what turns it into something real.

I built this to scratch my own itch – in companies we use different data services that produce charts in different styles, and unifying them for reports or presentations is a pain. Sometimes you have a CSV export, sometimes just a screenshot from a dashboard, and manually recreating everything is tedious.

How it works: - Paste a screenshot, drop a CSV or JSON, or describe what you want in text - AI extracts the data and generates an editable chart - For clean CSVs, it parses locally without hitting the AI - Customize colors, themes, labels, and data directly in the browser

Export formats: SVG, PNG, animated GIF, MP4, WebM, and Lottie (for web/app animations).

Built with TanStack Start, Recharts, and Gemini API. Free to use.

Would love any feedback, especially on the UX and what export formats or chart types you'd find useful.

What are the potential legal and ethical ramifications for developers and users in using such emulation methods or accessing private APIs?

Best of luck Nicolas. For occasional complex data mappings, how does Lume adapt? Can users customize for specific one-off tasks?
Add a little todo for each page perhaps?
Thank you. I was just thinking of creating one last night.
