A traceable link graph
Every observed edge records the page it came from and the anchor text, so a bridge can always be traced back to an observation.
A public, traceable index of clearnet ↔ onion links
Two webs.
One bridge.
OnionBridge maps the connections between clearnet sites and onion services. It crawls pages through Tor, records every link it observes with its source, and keeps curated clearnet ↔ onion mappings with provenance. Anyone — people or agents — can query the bridges.
What OnionBridge is
A link graph, a Tor navigator and a public API.
Curated mappings
Known clearnet ↔ onion pairs carry their source and evidence URL, so official mirrors are distinguished from incidental links.
Built for humans and agents
Browse the map or the Tor navigator in HTML, query the JSON API, or connect an AI agent to the MCP endpoint over SSE.

Ask the archive
Ask questions about the method and the material behind OnionBridge. Answers are grounded in the archive and cite their sources.
The archive chat runs as a small WebAssembly island. It answers only from the documents collected here, and always cites them.
