## Two firmwares, same radio

As explained in [LoRa: what it is and how it works](/en/lora-what-is-how-it-works), LoRa radio is just the physical layer: the way bits become radio waves. Very different network protocols can be built on top of that radio. **Meshtastic** and **Meshcore** are the two most-used open-source firmwares today for turning a cheap LoRa device into a node of a decentralized mesh network, with no gateway and no central server.

They use the same radio, and often run on the exact same hardware, but they're not compatible with each other: a Meshtastic node can't exchange messages with a Meshcore one, because they speak different protocols. Choosing one or the other means choosing which network you join.

## Meshtastic: the de facto standard

[Meshtastic](https://meshtastic.org/) is the older, more mature of the two projects, with a large, active international community since 2020. Its core mechanism is **flood routing**: when a node transmits a message, every other node that receives it relays it further, up to a configurable hop limit. It's a simple, robust mechanism that works well on smaller or lower-density networks.

Strengths:

- Official apps for Android, iOS, Windows, Linux, and web, plus a wide range of third-party integrations (MQTT, Home Assistant, Telegram/Discord bots).
- Extremely broad hardware support: practically every ESP32/nRF52 board with a LoRa module (Heltec, LilyGo, RAK, Station G1/G2, and many more) has an official or community-supported Meshtastic target.
- Per-channel encryption (a pre-shared AES256 key) and public-key-encrypted direct messages between individual nodes.

The main limitation comes precisely from flood routing: on very dense or large networks, every message relayed by many nodes eats into shared bandwidth and "airtime," which on LoRa is a scarce, regulated resource (see the duty-cycle constraints covered in the intro article).

## Meshcore: built to scale better

[Meshcore](https://meshcore.co.uk/) is a newer project, explicitly designed to overcome the scalability limits of pure flood routing. Instead of relaying every packet on every node, it relies on **route discovery and optimization**: once an efficient path between two nodes is found, subsequent traffic tends to follow it instead of being re-broadcast across the whole network, reducing redundant traffic on denser networks.

Meshcore shares much of the hardware Meshtastic supports — boards like the Heltec V3, LilyGo T-Deck, and several RAK modules work with either firmware, depending on which image gets flashed — and offers dedicated multi-platform apps (Android, iOS, Windows, Linux, web). Security is also central here, with encryption designed around a model closer to point-to-point messaging between contacts.

Being younger, it has a smaller community than Meshtastic's, with less established documentation and fewer ready-made third-party integrations, but it's growing quickly among people running larger mesh networks who feel flood routing's limits.

> Meshtastic: huge community, mature tooling, simple (flood) routing. Meshcore: younger, routing
> built to scale on dense networks, growing community.

## Which one to choose

- If you want the largest community, the richest documentation, and ready-made integrations (Home Assistant, MQTT, bots), **Meshtastic** remains the safer choice, especially to get started.
- If you're building — or joining — a dense network with many nearby nodes, where flood routing starts saturating available bandwidth, it's worth evaluating **Meshcore** for its more efficient routing approach.
- Keep in mind the choice isn't locked to the hardware: many compatible boards can be reflashed with either firmware. It's locked to the **network** you join — check which firmware the local community you want to join actually uses. In Italy, for example, [Lora Italia](https://www.loraitalia.it)'s [Telegram group](https://t.me/meshtastic_italia_community) and [node map](https://map.loraitalia.it/) make it immediately clear which firmware is in use, before deciding.
