Self-hosted, tailnet-native peer-to-peer file transfer between your own machines — no cloud, no size limits, folders keep structure. Runs on any Linux box with Docker + Tailscale; first-class on ZimaOS/CasaOS.

https://www.youtube.com/watch?v=1Qy5gYrb8q4 — live mesh console, a machine-to-machine transfer, the storage picker, and public share links.
Pull the image (multi-arch: amd64 + arm64, cosign-signed)
docker pull ghcr.io/chicohaager/dropbridge:0.2.0
Highlights
- Living mesh console — every node's online-state, WireGuard link, telemetry, real latency
- Drag-and-drop, machine-to-machine transfer (peer-to-peer, no relay)
- Storage picker — choose which data disk received files land on (never eMMC/foreign fs)
- Public one-click funnel share links (path-scoped; the rest stays tailnet-only)
- Host networking so it sees your real tailnet identity (works with the ZimaOS App-Store Tailscale too)
Security
Full multi-perspective code + security audit passed: tailnet-only control plane (LAN-spoof-proof serve header), fail-closed ingest, SSRF-safe peer URLs, internal-metadata never shareable, free-space guard, loud errors (no "delivered" on a failed transfer). Image ships with SLSA provenance + SBOM and is keyless cosign-signed.
