A mesh radio is only half the story. The other half is the software that decides what your group can actually do with it — coordinate, stay accounted for, keep private things private. Outpost starts from everything the established mesh apps already do well, then adds the layer they leave out: the human one. New to mesh entirely? Start with What is Outpost?
The established mesh apps — Meshtastic and MeshCore are the names most people know — are good tools, and Outpost doesn't pretend otherwise. Outpost firmware is built on Meshtastic's radio foundation, and it says so. Everything those apps do, Outpost does too:
Group channels and direct messages between radios, relayed hop by hop across the mesh — no towers, no internet, no subscription.
Private channels carry their own encryption keys. Strangers' radios can relay your traffic; they can't read a word of it.
Radios share their positions, and you see your group on a map — where everyone is, and how far.
Battery, signal, and device and environment readings from every node, so you know the state of the network — and of the radios people are counting on.
Every radio repeats what it hears, so the network reaches around ridges and down valleys far beyond any single radio's range.
GPS trackers ride along as full mesh members, and phone apps pair over Bluetooth to type, read, and manage it all.
Position precision is the radio's standard per-channel setting, and Outpost surfaces it per room — with one shared default for public rooms and one for private ones. Each room picks its own: exact, fuzzed to a grid cell of about a mile, three, five, or ten — or no position broadcast at all. Your convoy can see you precisely while a public room sees “about a mile away,” because where you sleep is nobody else's business.
Guided web flashing isn't ours alone — Meshtastic runs one too. Outpost's standalone Web Flasher does the same job for Outpost builds: pick your device from a picture gallery — or let the page detect the radio on the cable — choose the Stable or ProtoBox channel, back the radio up first, then flash. Every listed image is verified a true factory image before it ships.
Downloadable apps aren't unique to Outpost — MeshCore offers them too. Outpost's Expansion Apps install from a store on the device itself and run as sandboxed Lua on the deck and the phone — RF Monitor, Airtime, Mesh Surveyor, even a Breakout game — each limited to the abilities it declares: never your encryption keys, never the radio's settings, no network.
This is the layer the other apps leave to group chats, memory, and luck. Each of these is in the shipping Outpost software — the one marked “coming soon” is labeled, honestly.
Your profile — who you are, your vehicle, your party, your medical note — is stored on the radio itself, not in an app or a cloud account. Five privacy audiences (Public, Friends, Room, Ask, Off) decide who sees what, and the medical block has its own, tighter audience. Why it matters: a node on the mesh is a person with a story, not just a number — and you stay in control of it.
Rooms carry a category — Convoy, Basecamp, or Trail — and lead with the tools that activity needs: driving tools up front for a convoy, bulletins at basecamp, waypoints and navigation on the trail. Nothing is locked away; the room just knows what you're doing. Why it matters: the right tool is the first one you see, with gloves on, in the dark.
Ask the room a question — route, camp, dinner — with a deadline from 15 minutes to 24 hours, and watch the votes tally live. The result posts into the thread when the poll closes. Why it matters: group decisions get made in the conversation, not across three side chats nobody can find later.
Pin the plan where the whole camp sees it: the latest bulletin sits at the top of the room. Why it matters: “where are we meeting, and when” stops being a message that scrolled away an hour ago.
One tap says “I'm OK” — on a schedule if you like. Arm a return time, and if you haven't checked in or moved by the deadline plus a grace period, your group is alerted with your last known position. Why it matters: it's a dead-man switch for the backcountry — silence itself becomes the alarm.
A direct message is marked “✓ delivered” only when the other radio actually acknowledges it. A room message claims only “sent” — no client can prove a broadcast was carried, so Outpost never claims it was. Why it matters: in a real emergency, “sent” isn't good enough — and a receipt that overclaims is worse than none. You need to know exactly what you know.
A plain stock-firmware radio — a tracker, say — can't hold a profile of its own. An Outpost radio hosts one for it and answers on its behalf, marked honestly as “via” the host. Why it matters: every node in your fleet gets an identity, even the ones that can't speak for themselves.
The desktop console is a single HTML file: open it in Chrome or Edge, plug in a radio, and you can configure every setting, manage rooms and profiles, back everything up encrypted, and watch the live radio log. No install, no account. Why it matters: the workbench travels as easily as the radios do.
Draw a fence on the map — or a radius around any waypoint — and get an alert when your node, or a watched one, enters or leaves it, routed private, to friends, to favorites, or to chosen rooms.
Coming Soon
A mesh isn't a gadget looking for a problem. It's for the places and days where the problem is that nothing else works.
A dozen trucks strung over miles of dirt lose sight of each other by the second switchback. On the mesh, the tail can talk to the lead, a stopped truck shows up on everyone's map, and a waypoint for the turnoff reaches the whole convoy at once.
Camp staff, gate crews, and kitchen teams spread across a site that cell service barely reaches. A bulletin pins the day's plan, rooms keep each crew's chatter separate, and one radio at the high point relays for everyone.
Split up for the day, stay accounted for. Check-ins say “still fine” without a phone call, positions stay fuzzed to anyone outside the group, and if someone doesn't come back by the armed time, the overdue alert carries their last known position.
Acres of ground, dead zones everywhere, and people working alone. Sensor and tracker nodes report in, a vehicle crossing a fence line can raise an alert (coming soon), and “anyone seen the side-by-side?” becomes a look at the map.
When the power and the towers go together, a neighborhood mesh keeps working on batteries and solar: who's checked the elderly neighbor, which street has a generator and a spare can of fuel, where the chainsaw crew is needed next.
Search teams fan out beyond radio-relay range of a single repeater; a mesh of handhelds, vehicle nodes, and a relay on the ridge keeps teams, base, and found-person reports connected — with breadcrumbs showing exactly which ground has been covered.
Anchorages and desert camps where the nearest tower is a rumor. Raft-ups coordinate by room instead of shouting, dinghies carry trackers, and the group's plan for tomorrow is a bulletin, not a dock walk.
Nothing below is an argument that a mesh fixes a disaster. It's the record of what happened to communications in four of them — and a plain look at the gap a local mesh is built to fill. In each case, the failure wasn't the forecast or the warning existing. It was the last mile: getting word to people, and hearing back.
When Maria crossed Puerto Rico, the island's phone network effectively ceased to exist. In the days after landfall, roughly 95% of cell sites were out of service, according to FCC status reports — and in 48 of the island's 78 municipalities, every single site was down. A month later, about two-thirds of sites were still dark. People had no way to call for help, reach family, or learn which roads, pharmacies, and water points were open.
With a mesh in place: radios that run for days on batteries and solar don't need the grid or the towers. A relay on a rooftop or a hilltop, and a handheld in every neighborhood, could have carried the small, vital traffic — “we're safe,” “we need water at this street,” “the clinic is open” — while the towers were rebuilt around them.
Helene's flooding cut Asheville off from the outside: roads impassable, power out, and cell service and internet down for days, as the Associated Press reported at the time. Residents gathered at a fire station just to reach WiFi. Across the mountains, families who couldn't reach loved ones had no way to know whether silence meant “safe” or something worse.
With a mesh in place: a handful of radios — at fire stations, churches, and crossroads, relayed by a solar node on high ground — could have linked cut-off communities to each other: welfare checks passed street to street, supply needs collected at one point and read out at another, check-ins standing in for the phone calls that couldn't get through.
As fire drove into Lahaina, Maui County sent repeated evacuation alerts to phones — at least 14 of them, by the county's later account. Most never arrived: the county later found that all 21 cell towers serving West Maui had failed, and the island's emergency sirens were never activated. More than a hundred people died. For many residents, no warning came at all.
With a mesh in place: a radio net doesn't ask a tower's permission. An evacuation message passed radio to radio — from a fire station to handhelds, trucks, and kitchen counters across town — travels a path fire can't burn down one tower at a time, and every radio that repeats it is also a person who has heard it.
The National Weather Service issued flash flood warnings hours ahead, including a warning in the small hours of July 4. But along the Guadalupe there was no siren system — Kerr County had debated one for years and deferred it — and the county's phone-alert system wasn't activated in the critical hours. Riverside camps sat in stretches known for weak cell service, and the river rose in the dark, about 26 feet in under an hour by gauge readings, while people slept. More than a hundred people lost their lives.
With a mesh in place: radios linked camp office to camp office up and down the valley could have carried a single warning node to node in minutes — and a camp that checks in its cabins, and is expected to, turns “no answer” itself into an alarm. Local, awake, and already there: that's the layer that was missing.
A mesh is not a siren system, a weather service, or a rescue service, and it doesn't replace any of them. It's the layer a community owns outright — the one still standing when the big systems are the thing that failed.
Here's the whole argument in one breath: the alternatives give you a radio network. Outpost gives you a radio network that knows who everyone is, what room you're in, whether your message actually arrived, whether you made it back — and keeps your exact location yours. More safety systems. More features. More convenience. And it isn't five tools taped together: it's one system across your handhelds, your vehicles, your relays and trackers, your phone, your watch, and your desktop — every one of them speaking the same language, every one of them still working when the towers aren't.
Your radios are already the hard part. Choosing the software that runs them is the clutch move. Make it Outpost.
