Open workflowTrust is a feature
Local is a tested data path, not a slogan.
Every rebuilt flagship tool uses browser APIs for its primary operation. That processing boundary is implemented and tested for each tool that carries the local label.
- Defined payload boundary
- Local tool operations do not submit entered values to Laravel or place them in the page URL.
- Explicit limitations
- Lossy formats and unverified JWTs are labelled before you trust the result.
- Small, lazy-loaded modules
- Heavy parsers load only for the workflow that needs them.
- Easy corrections
- A public support route exists for factual, accessibility and security reports.
