MeshGrid
Off-grid team mapping and messaging without internet.
What it does
Stay connected when networks fail. MeshGrid combines LoRa hardware with a robust iOS app to create an independent, off-grid coordination hub. Share real-time locations on shared maps, send encrypted messages, and manage field missions without internet or cellular signal. Perfect for Search & Rescue and disaster response, MeshGrid features MGRS/UTM support and a high-performance, memory-efficient architecture. Built for the moments when communication is a necessity, not a luxury.

- OGOff Grid – Run AI text, image gen, vision offline on your phoneFeb 2026 · github.com · ▲124
Your phone has a GPU more powerful than most 2018 laptops. Right now it sits idle while you pay monthly subscriptions to run AI on someone else's server, sending your conversations, your photos, your voice to companies whose privacy policy you've never read. Off Grid is an open-source app that puts that hardware to work. Text generation, image generation, vision AI, voice transcription — all running on your phone, all offline, nothing ever uploaded. That means you can use AI on a flight with no wifi. In a country with internet censorship. In a hospital where cloud services are a compliance…
- RGRed Grid Link – peer-to-peer team tracking over Bluetooth, no serversMar 2026 · github.com · ▲54
I go on a lot of backcountry trips where I barely get cell service. If my group splits, nobody knows knows where anyone is until you regroup at camp or at your destination. You can buy Garmin radios or try to set up an ATAK, but ATAK is Android-only and assumes you have a TAK Server running somewhere to make use of all of the functionality. Cool tools themselves, but expensive to set up correctly. I just wanted two iPhones to share their location directly over Bluetooth when cell coverage was lacking. Red Grid Link does that. Start a session, and anyone nearby running the app shows up on…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
