# label-studio vs core

label-studio and core share 4 technologies: Autoprefixer, PostCSS, postcss-selector-parser, and pixelmatch. Both are written in TypeScript.

- [HumanSignal/label-studio](https://seerepo.com/r/HumanSignal/label-studio): Label Studio is a multi-type data labeling and annotation tool with standardized output format
- [stenciljs/core](https://seerepo.com/r/stenciljs/core): A toolchain for building scalable, enterprise-ready component systems on top of TypeScript and Web Component standards. Stencil components can be distributed natively to React, Angular, Vue, (+ more) and traditional web applications from a single, framework-agnostic codebase.
