Offline Protocol vs Meshtastic
Meshtastic is an open-source LoRa hardware mesh: it reaches long distances off-grid, but every user needs a dedicated LoRa radio device paired to a phone. Offline Protocol is a phone-native software mesh: it uses the Bluetooth LE and Wi-Fi radios already in phones, so there is no hardware to buy or carry, and it adds MLS encryption, Ed25519 identity, and serverless service discovery. If you want long-range, low-bandwidth off-grid links and do not mind carrying a radio, Meshtastic fits. If you want a Meshtastic alternative for phones without hardware, and higher bandwidth, Offline Protocol fits.

What is Meshtastic?
Meshtastic is a community-driven, open-source project that turns inexpensive LoRa radios into a long-range, off-grid text messaging mesh, with every radio rebroadcasting the messages it receives. Each radio pairs with one phone over Bluetooth, Wi-Fi or USB, so the phone is the screen and keyboard while the radios carry the messages. What is Meshtastic? in the Learning Center explains its routing, hardware and security.
How do Offline Protocol and Meshtastic compare?
Meshtastic trades bandwidth for long range on dedicated LoRa radios. Offline Protocol uses the radios already in phones, with shorter hops and more bandwidth.
| Capability | Offline Protocol | Meshtastic |
|---|---|---|
| Extra hardware | None, uses the phone radios | Yes, a dedicated LoRa radio device |
| Radios | BLE, WiFi Direct, internet | LoRa |
| Range per hop | Shorter, coverage grows with density | Long range, low bandwidth |
| Bandwidth | Higher, chunked transfer up to 100 MiB | Low, short text-scale messages |
| Routing | 8-hop relay with ack, retry, dedupe | Managed flood |
| Encryption and identity | MLS (RFC 9420), Ed25519 OfflineID | AES channel keys; per-node public-key DMs since firmware 2.5 |
| Service discovery | Serverless request and response | Channel broadcast |
| Form factor and buyer | SDK for product teams | Open hardware for hobbyists and off-grid |
| Licensing and cost | Mesh SDK free under AGPL-3.0, including in production. Closed-source and App Store apps need the commercial license; contact us for pricing. Hosted services from $0 (Free), $99 a month (Pro), $499 a month (Scale). Local mesh traffic is never metered. Pricing | Open source, GPL-3.0 firmware, free; each user needs a LoRa radio.

How is Meshtastic different from Offline Protocol?
Meshtastic is radio hardware each person carries; Offline Protocol is software on the phone they already have. Meshtastic is an open-source project that builds a LoRa mesh using managed flood routing. Its strength is range: LoRa radios trade bandwidth for distance, so a handful of nodes can cover kilometers of open terrain with no infrastructure. The tradeoff is that every participant needs a compatible LoRa radio device, which pairs to a phone over Bluetooth to send and read messages. It is consumer and hobbyist-leaning, popular for off-grid hiking, events, and experimentation.
Offline Protocol takes the opposite starting point: no extra hardware. It meshes the phones people already carry over Bluetooth LE and Wi-Fi, so coverage grows with the density of devices rather than the range of one radio. That means shorter hops but far more bandwidth, including chunked transfer up to 100 MiB, and it adds what a broadcast channel does not have: Ed25519 identity per device and serverless service discovery for invoking capabilities, all under MLS (RFC 9420) encryption.
The practical divide is who carries what. Meshtastic asks each user to own a radio. Offline Protocol asks each user to install an app. For a team shipping a product to people who will not buy hardware, that difference decides the project.
When should you choose Meshtastic or Offline Protocol?
Choose Meshtastic if you need kilometer-scale links across open terrain and your users can carry a LoRa radio. Choose Offline Protocol if you cannot ship hardware to every user and need a phone mesh with MLS encryption, device identity, and service discovery inside your own app.
When should you choose Meshtastic?
You need long-range, low-bandwidth links across sparse, open terrain, users are willing to carry a LoRa radio, and an open-source, community-driven, hobbyist-friendly stack fits the project.
When should you choose Offline Protocol?
You want a phone-native mesh with no hardware to ship, higher bandwidth, MLS encryption, device identity, and service discovery, delivered as an SDK your team builds a product on.

Offline Protocol vs Meshtastic FAQ
Is there a Meshtastic alternative that works on phones without hardware?
Yes. Offline Protocol is a phone-native mesh that uses the Bluetooth LE and Wi-Fi radios already in phones (WiFi Direct on Android, peer-to-peer Wi-Fi on iPhone), so there is no LoRa device to buy or carry. It relays up to 8 hops with MLS (RFC 9420) encryption and Ed25519 identity, and ships as an SDK you build products on. Meshtastic, by contrast, requires a dedicated LoRa radio.
What is the difference between Meshtastic and Offline Protocol?
Meshtastic is an open-source LoRa hardware mesh that uses managed flood routing and needs a dedicated LoRa radio device paired to a phone. Offline Protocol is a software SDK that meshes phones directly over Bluetooth LE and Wi-Fi with no extra hardware, adds MLS encryption, Ed25519 identity, and serverless service discovery, and is aimed at teams building products rather than hobbyist off-grid setups.
Can Offline Protocol reach the long ranges Meshtastic does?
No, and it is not trying to. LoRa is a long-range, low-bandwidth radio, so Meshtastic excels at sparse, off-grid, kilometer-scale links. Offline Protocol uses phone radios, so its reach per hop is shorter but coverage grows with device density, and it carries far more bandwidth, including chunked transfer up to 100 MiB. They suit different range and density profiles.
Which is better for building a commercial product?
If you cannot ship a radio to every user, a phone-native SDK is the practical path, and Offline Protocol is designed for that: a Rust core with a React Native binding, MLS encryption, and identity built in. Meshtastic is open-source and consumer or hobbyist-leaning, and depends on users owning compatible LoRa hardware.
How do licensing and cost compare with Meshtastic?
The Offline Protocol mesh SDK is free under AGPL-3.0-only, including in production, and local mesh traffic is never metered on any plan. Closed-source apps and apps distributed through the Apple App Store need the commercial license, which has no published price, so contact us for pricing. Hosted services are optional and run on Free ($0), Pro ($99 a month), Scale ($499 a month), and Enterprise plans. Meshtastic is free, open-source firmware under GPL-3.0, so its cost is the LoRa radio each user carries. See the Meshtastic introduction.
