Meshtastic vs Reticulum

Meshtastic is a ready-made LoRa messenger; Reticulum is a general encrypted network stack. How they differ and when to use each.

At a glance

	Meshtastic	Reticulum
What it is	LoRa mesh messaging and position firmware, designed to work with no internet or cellular	"Cryptography-based networking stack for building both local and wide-area networks with readily available hardware"
Routing	Managed flooding; next-hop for direct messages	Announces propagate via transport nodes (up to 128 hops by default); no node knows the complete path
Addressing	Node IDs; direct messages by public key	16-byte destination hashes replace IP addresses and ports
Encryption (documented)	AES-CTR channels (default key public); X25519 direct messages; header unencrypted; no forward secrecy	Ed25519, X25519, AES-256-CBC with PKCS7, HKDF; forward secrecy on links; no source addresses
Transports	LoRa, plus an MQTT bridge via an internet broker	RNode (LoRa), KISS/AX.25, TCP, UDP, AutoInterface, Backbone, I2P, serial, pipe
Slowest usable link	Presets from 0.34 kbps (Long Moderate) in EU_868	Works on media with more than 5 bits per second; MTU at least 500 bytes
Messaging apps	Official Android, iOS and web clients	Sideband, NomadNet, MeshChat; LXMF propagation nodes
Message size	About 200 bytes of text	LXMF adds 111 bytes of overhead; attachments over faster links
Hardware	Many ready-made boards	RNode firmware on common boards or ready-made; software runs on Python 3 (including a Pi Zero)
Licence	GPL-3.0 (firmware)	Reticulum License (not a standard OSI licence); protocol dedicated to public domain in 2016
Community size	See find a local mesh	No census: no central registry

Key differences

Complete system versus toolkit

Reticulum's design goal is that the network layer survives slow, unreliable or hostile media, so LoRa is one interface among many. Meshtastic is built for a single radio type and packages the radio, mesh, apps and settings together. If you want something that works from a phone five minutes after flashing, that is Meshtastic. If you want to run a service, share files or link a LoRa segment to a TCP backbone, that is what Reticulum's interfaces are for.

Routing and addressing

Meshtastic rebroadcasts packets and relies on a hop limit (default 3, maximum 7). Reticulum nodes send announces; each transport node records the most direct way to get a packet one hop closer to a destination, and the manual says no single node knows the complete path. Because destinations are hashes rather than addresses, packets carry no source address. See how mesh routing works.

Encryption

Per the project documentation, Reticulum creates ephemeral keys for each link, which gives forward secrecy, and the initiator of a link can remain anonymous. Meshtastic documents that its default channel key is public, its header is never encrypted, and it has no forward secrecy. On paper Reticulum's model is stronger, but this is each project's own documentation: we read no independent audit of either. See privacy and encryption.

Apps and store-and-forward

Reticulum's LXMF messaging layer supports propagation nodes that hold messages for offline users, and messages can travel as QR "paper messages". Sideband offers messaging, voice, telemetry and files; NomadNet is a text-based tool for pages and messaging (beta). Meshtastic's overview describes a node buffering packets for a disconnected client. We did not read the documentation for a separate Meshtastic store-and-forward module, so we do not compare them as named features. See clients and apps.

Effort and maturity

Meshtastic has the lower setup effort (flash Meshtastic). Reticulum needs command-line tools and configuration files (RNode and Reticulum setup). As of 29 October 2026, Meshtastic firmware has 8,495 GitHub stars and its latest release is v2.7.26 (24 June 2026); Reticulum has 7,642 stars and release 1.5.5 (29 September 2026). The Reticulum project describes a single lead maintainer.

What neither does

Neither carries ordinary web browsing over LoRa. See what you can actually do.

In the UK

Meshtastic uses region EU_868 in the UK. Reticulum over LoRa uses whatever radio parameters you configure on the RNode, so you are responsible for staying inside Ofcom's limits. We did not read any RNode UK-specific frequency or duty-cycle guidance, so this site gives none.

Over TCP or Wi-Fi, no radio licence question arises for Reticulum. If you carry it over amateur AX.25 packet radio, amateur licence rules apply, including limits on obscuring message content.

Which should you choose?

Local text and position messaging with the least effort: Meshtastic.
An encrypted stack that spans LoRa and the internet, with files and propagation nodes: Reticulum.
Hardware: many boards support more than one firmware, but support differs board by board. Check before you buy in the hardware buyer's guide.

Network pages: Meshtastic, Reticulum. Not sure: which mesh is right for you.

FAQ

Is Reticulum better than Meshtastic?

They do different jobs. Reticulum is a general networking stack with strong documented cryptography and several transports; Meshtastic is an easier, finished LoRa messenger with a larger hardware and app ecosystem.

Can Reticulum and Meshtastic talk to each other?

We found no documented bridge between them. They use different protocols, so treat them as separate networks.

Can Reticulum run over LoRa in the UK?

Yes, using an RNode on an 868 MHz board, with your own settings kept inside the Ofcom IR 2030 limits. See RNode and Reticulum setup.

Does Reticulum let me browse the internet over LoRa?

No. LoRa links are far too slow for web browsing. Reticulum can use TCP/IP as a carrier, but that is the internet link doing the work, not LoRa.
