Type any URL above. A peer in your network will fetch it, sign the bytes, and stream them back. Rendered in a sandbox. Verified by CID.

Relay mode

When on, this page listens for fetch requests from connected peers, fetches the URL from your network, signs the response bundle with your local Ed25519 key, and streams it back. Rate limits + size caps below.

Act as a relay

Off by default. Only turn on if you're happy to relay for trusted peers.

Max request rate req/min

Throttles incoming fetch requests per peer.

Max response size MB

Refuses to relay responses larger than this.

Timeout ms

Blocklist

Domains this relay will refuse to fetch (one per line). Adult, malicious, and known-bad domains recommended.

Fetch log

Everything this page has fetched or relayed. Kept in localStorage. Clear anytime.

Settings

Your peer identity

Ed25519 keypair generated on first load. Kept in localStorage.

Cache

FallStore-backed content-addressed cache. Repeat views are instant and independently verifiable.

Peer transport

FallLink WebRTC data channels + manual signaling. Paste an offer to connect.

Prefer LAN peers

Race N peers

Send fetch request to top N peers, use first verified response.

Signal / offer

Copy your offer to share with a peer, or paste theirs to connect.

FallLens

A sovereign browsing primitive. Type a URL. A peer in your trusted network fetches it, signs the bytes with their Ed25519 key, and streams them back to you. Your local page verifies the CID, then renders inside a sandboxed iframe.

Why

Sometimes your direct network can't reach a URL — blocked at the coffee shop, throttled, geo-region mismatch, or your friend just has a faster pipe. FallLens lets your peers help each other read the open web. When your network can't, a friend's can.

The primitives

FallLink — WebRTC data-channel peer transport
FallStore — content-addressed local cache (CID = SHA-256 of bytes)
FallSignature — Ed25519 peer signatures on every relay bundle

The trust model

Peers are not trusted with content authenticity — only with delivery. Every response bundle includes the peer's DID + signature + CID. Your local page verifies the CID before rendering. If the relayer swaps the bytes, the CID won't match, and the render is aborted.

Not a circumvention tool

FallLens is a general peer-assisted browsing primitive. Relayers set their own blocklist. Rate limits and size caps protect relays from abuse. Users are responsible for what they fetch. Content is rendered in a strictly sandboxed iframe.

A lens, not a browser. It sees what a friend sees.
