Noise IKpsk2 · ChaCha20-Poly1305 · Go

Mesh Networking
for the Next
Frontier

Encrypted, decentralized peer-to-peer networking with automatic NAT traversal, mesh DNS, and zero-trust routing all written in Go.

Noise Protocol

IKpsk2 handshake with ChaCha20-Poly1305 encryption. Mutual authentication and forward secrecy built in.

Decentralized P2P

Direct peer connections with coordinator-assisted discovery. WebSocket relay fallback when NAT won't budge.

Smart Routing

Automatic NAT traversal, mesh DNS resolution, and policy-based packet filtering across all nodes.

Infrastructure

Infrastructure as Turtle.
Connectivity, Hardened.

TunnelMesh turns any collection of nodes into a fully-routed, encrypted mesh. Deploy on bare metal, cloud VMs, containers — or all three at once.

  • Automatic peer discovery via coordinator
  • CGNAT IP allocation with mesh DNS
  • TUN device for transparent kernel routing
  • UDP primary, SSH fallback, WebSocket relay
  • RBAC with admin groups and role bindings

Object Storage

S3-Compatible Storage,
Built for the Mesh

Every coordinator ships with a fully-featured object store — no separate infrastructure required. Store, version, and replicate files across the entire mesh with standard S3 semantics.

  • Content-addressable deduplication — identical chunks stored once regardless of filename or bucket
  • Automatic replication — objects sync across coordinator replicas with chunk-level diffing
  • Full version history — every write is versioned; restore any previous state on demand
  • RBAC & file sharing — bucket-scoped access control with time-limited share links

Admin Interface

A Control Plane Built for
Secure AI & ML Sandboxes

TunnelMesh's web dashboard goes beyond network ops. A built-in markdown editor and dataframe viewer let researchers document experiments and inspect results without leaving the secure mesh boundary.

  • Markdown editor

    Write and publish experiment notes, runbooks, and model cards directly inside the mesh — served from S3, never exposed externally.

  • DataFrame viewer

    Inspect Parquet and CSV files stored in S3 straight from the dashboard. Filter, sort, and share slices with RBAC-controlled links.

  • Air-gapped ML sandbox

    Route GPU cluster traffic over the mesh for fully isolated training runs. No cloud egress, no data leakage, full audit trail.

Capabilities

Everything you need,
nothing you don’t

Mutual Authentication

SSH key-based identity. Every peer cryptographically proves who they are via Noise IKpsk2 before any data flows.

NAT Traversal

UDP hole-punching with PCP, NAT-PMP, and UPnP port mapping. Automatic relay fallback over WebSocket.

Mesh DNS

Automatic DNS resolution for all mesh peers. Reach any node by name — no /etc/hosts hacks required.

Object Storage

Built-in S3-compatible store with replication, versioning, deduplication, and RBAC across the mesh.

Docker Integration

Auto port-forwarding rules when containers start. Real-time stats, container control via web UI.

Observability

Prometheus metrics, Grafana dashboards, Loki log aggregation — built in from the ground up, not bolted on.
