Meshtastic vs MeshCore

As decentralized communication gains traction across hobbyist and professional communities alike, two names have risen to prominence in the open-source mesh networking scene: MeshCore and Meshtastic. Both are focused on enabling off-grid, low-power communication—but they take slightly different routes in terms of architecture, usability, and ecosystem.

Ropes and netting are tangled in an intricate arrangement.

🔧 Routing & Messaging Architecture

Meshtastic uses a custom LoRa-based mesh protocol that relies on managed flooding with a per‑packet hop limit (typically seven hops), and does not support dynamic path routing or deduplication.
MeshCore implements configurable multi‑hop routing with flood-then-memory behavior (learns paths and avoids unnecessary flooding), TTL limits, deduplication, and more efficient routing suited to pre‑planned or static mesh deployments.

📡 Transport & Hardware Flexibility

Meshtastic is tightly LoRa‑only, officially supporting ESP32-based boards with SX127x/SX126x radios.
MeshCore supports multiple transports (LoRa, BLE, Wi‑Fi, serial, UDP) and a much broader array of devices including Heltec V3, T-Deck/T‑Deck Plus, RAK4631, Xiao S3/C3, Seeed Studio T1000‑E, among others.

🔐 Encryption & Security

Meshtastic uses AES‑256 encryption with a shared channel key; admin messages now have enhanced encryption features. End-to-end per-connection encryption is optional.
MeshCore supports optional AES‑256‑GCM or ChaCha20‑Poly1305 encryption with identity attestation and control over keys, offering stronger end-to-end security.

🧩 Modularity & Extensibility

Meshtastic provides a firmware package for supported devices but offers limited customisation. It’s not designed for protocol extension or deep integration.
MeshCore is highly modular: users can flash specific firmware roles (Companion, Repeater, Room Server), use Python or JavaScript APIs, customize packet types, integrate custom sensors, and build structured mesh topologies.

🌐 Community & Ecosystem

Meshtastic has a large, engaged user base with active Discord, Reddit, GitHub, Telegram bots, MQTT gateways, and community-built extensions.
MeshCore has a smaller, more specialized community of developers and embedded systems engineers, with official CLI tools, Python/JS libraries, and firmware workflows.

🧭 Core Use‑Case Orientation

Meshtastic is tailored for spontaneous, dynamic LoRa mesh messaging—ideal for outdoor use, event communication, and simple off-grid chat.
MeshCore is geared toward planned or semi-static networks requiring structured roles, message persistence (via Room Server), telemetry, and efficient routing.
