Offline Protocol vs the alternatives
Last updated
If you are choosing how to build offline, peer-to-peer, or mesh connectivity, the honest comparison is not vendor against vendor but form factor against form factor. Offline Protocol is a software SDK that turns the phone radios people already carry into an encrypted mesh, with self-sovereign identity and serverless service discovery on top. Below is a factual, side-by-side view against Ditto, Bridgefy, Meshtastic, goTenna, Berty, Briar, Amazon Sidewalk, and Google Nearby Connections, followed by a detailed page for each.
| Capability | Offline Protocol | Ditto | Bridgefy | Meshtastic | goTenna | Berty | Briar | Amazon Sidewalk | Nearby Connections |
|---|---|---|---|---|---|---|---|---|---|
| Extra hardware required | No, uses the phone radios | No, runs on existing devices | No, uses the phone radios | Yes, LoRa radio device | Yes, mesh radio device | No, uses the phone radios | No, uses the phone radios | Yes, Amazon gateways | No, uses the phone radios |
| Transports | BLE, WiFi Direct, internet | Bluetooth, LAN, P2P WiFi, server | Bluetooth, WiFi Direct | LoRa radio | Proprietary radio | BLE and internet | Bluetooth, WiFi, Tor | BLE and 900 MHz LoRa | Bluetooth, BLE, WiFi |
| Phone-native | Yes | Yes | Yes | No, needs a paired radio | No, needs a paired radio | Yes | Yes | No, needs a gateway | Yes |
| Encryption and identity | MLS (RFC 9420), Ed25519 OfflineID | Transport and app-level encryption | App-level encryption | AES on channels, no per-user identity | Encrypted radio messaging | End-to-end, no phone number | End-to-end encrypted | Encrypted device traffic | Encrypted transport |
| Service discovery | Yes, serverless request and response | Sync-based, via replicated data | No, messaging only | No, channel broadcast | No, messaging only | Messaging focused | Messaging focused | IoT connectivity | Advertise and discover |
| Topology | Routed multi-hop mesh | Sync replication | Multi-hop mesh | Multi-hop radio mesh | Multi-hop radio mesh | Peer-to-peer | Peer-to-peer | Gateway to internet | Direct links |
| Server optional | Yes, serverless by default | Yes, server optional | Yes | Yes | Yes | Yes, no central server | Yes | No, gateway backhaul | Yes, direct links |
| Primary form factor | SDK (Rust core, React Native) | SDK (offline database and sync) | SDK (mobile mesh) | Hardware and open firmware | Hardware and companion app | Open-source app | Open-source app | Gateway network | Android platform API |
| Target buyer | Product and platform teams | App and data teams | App teams | Hobbyists and off-grid users | Field and outdoor users | Privacy-first users | Activists and journalists | IoT within the US | Android developers |
Values reflect each vendor's public documentation and product claims. Where a claim is specific, the per-vendor pages cite the source. Offline Protocol facts are drawn from production: 350,000+ devices across 80+ countries.
How to read this comparison
The clearest split is form factor. Meshtastic and goTenna are radio products: you buy and carry a device, and the phone is a companion. Berty and Briar are finished open-source messaging apps, not toolkits to build on. Amazon Sidewalk is a gateway network for low-bandwidth IoT that leans on Amazon hardware and internet backhaul. Google Nearby Connections is an Android direct-link API rather than a routed mesh. Ditto is an offline-first database and sync engine. Offline Protocol, Bridgefy, and the SDKs are software that runs on phones already in the field, and among those Offline Protocol is the transport, identity, and coordination layer with routed multi-hop mesh, self-sovereign identity, and serverless service discovery.
