Decentralized Connectivity Substrate

Physarum

A network layer for agentic internet, enabling permissionless peer-to-peer discovery and communication between agents and humans.

Built for|

Pipes not platforms.

Existing realtime infra was built for human-to-human video calls. Agents need a zero-config, permissionless solution for discovering those they wish to serve, and raw voice + data transport at the lowest possible cost.

Discovery

Direct peer discovery between agents and humans for scalable collaboration. Permissionless exchange of signalling for p2p connectivity.

Voice

Low-latency audio streams between agents and humans over WebRTC. A marketplace for speech-to-text and text-to-speech services.

Video

Camera, screen, and generated video. Streamed peer-to-peer with minimal latency. Scaled through mesh topology.

Data

Arbitrary structured, encrypted data channels for agent-to-agent coordination. Bidirectional, lightning fast and truly peer-to-peer.

No API keys.

Fully x402 and MPP compatible. For the agent compatible future.

How It Works

01
Discover

Peers broadcast their presence and capabilities across the mesh. Task completion, voice synthesis, robotic control, or anything else.

02
Connect

Agents and humans negotiate direct WebRTC connections through the mesh itself. No centralized broker required.

03
Stream

Voice, video, and data flow peer-to-peer with minimal latency, optionally propagating between peers in the network.

04
Relay

Decentralized relay infrastructure handles NAT traversal and fallback routing at commodity cost. No single-provider bottleneck.

05
Scale

The mesh is permissionless. Any agent, human, or device can join and contribute services, growing the network with every new node.

Why Physarum?

Infinite Scale

Mesh networks scale horizontally by default. When session requirements outgrow mesh topology, decentralized SFUs and MCUs provide on-demand vertical integration.

Decentralized Relay

TURN and relay nodes operated by independent providers. No single point of failure means traffic routes through a resilient, distributed network instead of one vendor's data centers.

Open Infrastructure

Physarum is 100% open source. No vendor lock-in. Standard WebRTC under the hood with world class implementations of the WebRTC protocol. Switch providers or self-host anytime.

A Voice For All

Bring us your voiceless agents. We connect them with speech-to-text and text-to-speech over the permissionless WebRTC mesh. All robots need to speak.

No API Keys

The age of the [API key] is over, the age of the [Machine Addressable Payment] has come. We are fully compatible with machine to machine payment protocols to unblock the future of agentic internet.

Commodity Pricing

Pay for bandwidth, not platform markup. Infrastructure cost, not perpetual rent. A competitive marketplace for connectivity means prices track real resource costs, not vendor lock-in.
