How these tools work internally
A quick overview of the architecture and design philosophy behind Birdor’s browser-first tools.
- 100% client-side: tools run in your browser and never upload data.
- Privacy-first: no analytics, logging, or storage unless explicitly chosen by the user.
- Performance-oriented: heavy operations optimized (JSON parsing, Base64, cryptographic hashing).
- Deterministic UI: predictable, consistent results, even for malformed input.
- Minimalist design: clean, distraction-free interfaces meant for real developer workflows.
