Tools Documentation
Explore all 107 tools across eight focused categories. Every entry below is generated from the live catalogue, so the documentation and available routes stay in sync.
The default privacy model is local browser processing. In practice, this means:
- Text, code and uploaded files are processed locally unless a network tool explicitly needs to contact an endpoint
- API, DNS, latency and WebSocket tools send only the request you initiate to the displayed destination
- Some tools save preferences or history in your browser storage so they can be restored later
- Page-level analytics may record visits, but tool input and generated output are not included
Each network-capable tool explains its boundary in the interface. Review the destination before sending credentials or private data to a third-party service.
