SVG Sanitizer and Theming Pipeline
A developer tool that cleans exported SVGs, namespaces IDs and classes, prevents style collisions, and preserves dark-mode theming support. It solves a concrete integration pain for teams that know SVG is the right answer but struggle with unsafe design-tool exports in real apps.
Why this matters
You switch from raster icons to SVG because it scales better, only to discover a new class of bugs. Icons exported from design tools arrive with duplicate identifiers, embedded styles, and assumptions that break when many assets live in the same DOM. In a large app or plugin ecosystem, similar icons inherit the wrong colors or references collide in unpredictable ways. You can isolate every icon manually or scrub every export by hand, but both options slow down designers and frontend engineers. What you need is a safe pipeline that makes SVGs production-ready without sacrificing theming or forcing everyone to learn the internals of vector markup.
- · Built for Frontend platform teams, design system maintainers, and plugin ecosystems that embed many inline SVG icons from designers or third-party contributors..
- · Most likely monetization: SaaS subscription.

- Recruit 10 teams with large icon sets and measure cleanup time saved
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1A free open-source package may satisfy most developers if the core problem is narrow and technically straightforward.
- 2Teams may reduce the need by using SVG sprites, image backgrounds, or fully isolated icon components instead.
- 3Designers and engineers may not agree on a workflow change unless the tool integrates tightly with existing export paths.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Several comments described a specific integration problem after moving to SVG: duplicate IDs and class names from design exports caused icons to affect each other in the DOM. The workaround of isolating each icon was said to work well but added implementation effort, while manual cleanup was considered annoying. This is a focused, workflow-friendly pain with a clear digital fix.
