Knit vs Meshtastic
Two open-source meshes with opposite ingredients — dedicated long-range radios, or the phones already in everyone's pockets.
Last reviewed: August 2026
Meshtastic and Knit solve the same problem — messaging where there's no network — with opposite ingredients. Meshtastic is a LoRa radio project: buy small dedicated radios, flash them, and get a mesh that hops kilometres at a time. Knit is just software: the mesh is made of the phones everyone is already carrying.
The short version: if you can plan ahead and put a radio in every pocket, Meshtastic reaches distances no phone can. If the moment has already arrived — the crowd, the blackout, the venue — Knit is the mesh you can raise right now, because the hardware is already there.

| Kilometres of range per hop | No, tens of metres | Yes |
| Multi-hop mesh — messages relay beyond your own radio | Yes | Yes |
| Open room with everyone nearby1 | Yes | Yes |
| End-to-end encrypted direct & group chats | Yes | DMs yes; channels share one key |
| Forward secrecy2 | Yes | No |
| Photos, GIFs & voice notes | Yes | No, text and location |
| Live positions on a map | No | Yes |
| Store & forward for offline peers | Yes | Router nodes only |
| On-device AI moderation | Yes | No |

| iPhone app | No | Yes |
| Free, no ads, open source | Yes, GPLv3 | Yes, GPLv3 — radios cost extra |
- 1Knit's Nearby room is an open broadcast, plaintext by design — like talking out loud in a crowd. Meshtastic's default channel ships with a publicly known key, which comes to the same thing.
- 2Knit rotates keys per block of messages, not per message, and a chat with someone on an older Knit build falls back to the previous static-key scheme, which has none. Spent keys are deleted, so mesh traffic recorded today can't be decrypted later. Meshtastic's own documentation states it does not implement forward secrecy.
- 3Knit's Internet relays are opt-in and carry only conversations you already started nearby, as sealed frames the relay can't read — no accounts, no discovery, and you can run your own. The Nearby room stays radio-only.
Where Knit wins: the mesh you already have
Knit's whole pitch is that there's nothing to buy. Install it and the crowd is the infrastructure: every phone relays sealed messages for every other, and the denser the crowd, the stronger the mesh gets. A Meshtastic mesh only exists where someone prepared it — radios bought, flashed, charged and physically carried — which is exactly right for an expedition and exactly wrong for a festival, a blackout or a march that started an hour ago.
It's also a full messenger rather than a radio terminal. LoRa's packets are tiny, so Meshtastic carries text and GPS positions; Knit meshes over Wi-Fi Aware as well as Bluetooth LE, and that bandwidth buys photos, GIFs and voice notes fetched on demand, named members-only groups that are end-to-end encrypted like every direct and group chat in the app, contact verification by safety number or QR code, and an open Nearby room with an on-device AI filter screening abuse and blurring explicit images without an upload anywhere.
The definitive case is spontaneity. If you didn't know this morning that the towers would be down tonight, Knit is the mesh that can still happen.
Where Meshtastic wins: kilometres, not metres
A single LoRa hop covers kilometres on a good day, and the radios sip power for days on a charge. Put a solar repeater on a hill and a valley is covered. Add live GPS positions on a shared map, clients for iPhone, Android and the web, optional MQTT bridges to the internet, and one of the most active hobbyist communities in radio, and you have the obvious pick for trails, overlanding, event ops and preparedness kits — places where distance beats everything and planning is part of the fun.
The cost is that preparation. Every participant needs a configured, charged radio in hand before the mesh exists — fine for the group that packs ahead, useless for the crowd that didn't.
Security, side by side
Since firmware 2.5, Meshtastic encrypts direct messages with per-node public keys, while channels are sealed with a single shared key — everyone holding the channel key reads everything on it, and the default public channel's key is public knowledge. Knit's sealed side is direct and group chats — end-to-end, down to the mentions and image attachments, with per-member keys in groups and in-person verification by safety number or QR code. Its open side is the public Nearby room: an open broadcast, like talking out loud in a crowd, and Knit never pretends otherwise.
Forward secrecy is the sharpest difference. Meshtastic's own documentation says it has none — traffic captured today can be decrypted whenever a channel key or node key leaks later. Knit's direct and group chats rotate keys as the conversation runs and delete the spent ones — per block of messages, not per message, with a fallback to the old static-key scheme toward peers on older Knit builds — so recorded mesh traffic stays shut. Messages are also encrypted at rest under a hardware-backed key that stays out of cloud backups, so reading them takes unlocking the device, not stealing it.
The browser demo shows the hop-by-hop idea without installing anything: knock out a cell tower, then walk a message across a crowd.
Choose Meshtastic if…
- Your group plans ahead and can put a radio in every pocket — then kilometres of range are yours.
- You want live positions on a shared map: trails, overlanding, event ops, search parties.
- You enjoy building the network itself — solar repeaters, MQTT bridges, telemetry — not just chatting over it.
Choose Knit if…
- The mesh has to exist right now, out of the phones people already carry.
- You want a real messenger on it: photos and GIFs, named encrypted groups, reactions and history.
- Forward secrecy matters to you — radio traffic recorded today shouldn't be readable later.
- Everyone nearby should be able to join — no purchase, no flashing, no setup.
Common questions
Can Knit and Meshtastic talk to each other?
No — they can't even hear each other. Meshtastic runs on LoRa radios in the sub-GHz ISM bands; Knit uses the Bluetooth and Wi-Fi radios inside a phone. Different hardware, different bands, different protocols.
Which one has more range?
Meshtastic, by a mile — literally. One LoRa hop covers kilometres where a Knit hop covers tens of metres. Knit makes up ground in crowds, where every phone extends the chain and messages wait for a path when there isn't one, but in open country dedicated radios are the only thing that reaches.
Is Meshtastic more secure than Knit?
They differ most on groups and on forward secrecy. Both encrypt direct messages end-to-end; in Knit that extends to group chats too — direct and group conversations are sealed per member, down to mentions and image attachments — where a Meshtastic channel shares one key among everyone on it, and the default channel's key is public knowledge. And Meshtastic's own documentation states it has no forward secrecy, so captured traffic is readable if a key leaks later; Knit rotates keys per block of messages and deletes the spent ones, falling back to the old static-key scheme only toward peers on older Knit builds. Treat the open surfaces on both — Knit's Nearby room and Meshtastic's default channel — as talking out loud.
Can I run both?
Yes, and preparedness-minded people often will. They use different radios entirely, so they don't compete for anything — Meshtastic in the go-bag for range, Knit on the phone for the crowd around you.
Which one belongs in an emergency kit?
For the kit you pack in advance, Meshtastic: radios, chargers, maybe a repeater. For the emergency you didn't pack for, Knit: the mesh assembles itself out of whoever is around, on hardware nobody had to remember to bring.
