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…

Hi HN, I’m building Waycore, an open-source project exploring what a flexible, offline-first field computer should look like for outdoor, survival, and off-grid scenarios. The core goals are adaptability and resilience: modular hardware (external sensor/tool modules) extensible OS with support for external apps (guidelines in progress) no required internet connection — maps, models, and knowledge work offline optional LTE/Wi-Fi when available and explicitly enabled A major focus is on-device agentic AI, not just chat or image recognition. The AI is intended to: read live sensor…

A couple of months ago, I built this app to help identify people stuck under rubble. First responders have awesome tools. But in tough situations, even common folks need to help. After what happened in Myanmar, we need something like this that works properly. It has only been tested in controlled environments. It can also be improved; I know BLE is not _that_ effective under rubble. If you have any feedback or can contribute, don't hold back.

I built Signet in Go to see if an autonomous system could handle the wildfire monitoring loop that people currently run by hand - checking satellite feeds, pulling up weather, looking at terrain and fuels, deciding whether a detection is actually a fire worth tracking. All the data already exists: NASA FIRMS thermal detections, GOES-19 imagery, NWS forecasts, LANDFIRE fuel models, USGS elevation, Census population data, OpenStreetMap. The problem is it arrives from different sources on different cadences in different formats. Most of the system is deterministic plumbing - ingestion, spatial…

I've decided to open source the project I've been working on called Hyperspace. Hyperspace is a suite of software implementing a wireless mesh network for IoT devices. My main requirements are listed on my repo but I'll copy them here. 1. The mesh shall enable nodes to route packets amongst themselves. 2. The mesh shall allow nodes with limited power to participate in routing packets. 3. The mesh shall be IPv6 based. 4. The mesh shall be local. I.E. not require connection to a remote server. 5. The mesh should provide 3D location to nodes in the network. Nodes use the Decawave DW1000 UWB…

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…

I created Firezone to make it easier to host and manage your own WireGuard VPN server. While working at Cisco as a security automation engineer I experienced a lot of unnecessary pain managing secure network-level access into our cloud VPCs. I tried OpenVPN Access Server but I personally feel that security software should be open source to be validated (and improved) by the community. I discovered WireGuard and quickly fell in love with it, but soon found managing the peer configs to be a bit tedious and error-prone. So I built some convenience functionality on top, added a simple Web UI,…

Hello Everyone, I'm excited to introduce a new open-source observability platform and would love to hear your feedback. We are aware that there are lots of open-source/commercial tools out there. However, we believe that monitoring the clusters and extracting actionable insights requires deep know-how about the tools/domain. We mainly focused on this problem. - Alaz is an eBPF agent installed on your K8s cluster as DaemonSet. Thanks to eBPF, Alaz collects traces directly from Linux kernels. This means there's no need for sidecars, instrumentations, or service restarts. - The UI not…

ServiceRadar is an open-source platform for distributed, secure network management and observability, scaling to 100k+ devices. Born from frustration with complex traditional NMS tools like Zabbix, it bridges legacy (SNMP/syslog) and modern (gNMI, OTLP) protocols for cloud-native environments. We built ServiceRadar to simplify monitoring hybrid telecom networks, evolving it into a Kubernetes-native solution with Helm and Docker support. It uses mTLS with SPIFFE/SPIRE, NATS JetStream for event streaming (90M+ EPS), and SRQL for intuitive queries. Integrated with OpenTelemetry,…

Hi HN, I am shubham a 3d artist who learned coding in college as an I.T. graduate know logics but not an expert as i just wanna try my hands on to ai So i built Resilient Workflow Sentinel this is offline ai agent which classify urgency (Low,Medium and HIgh) and dispatches to the candidates based on availability Well i want an offline system like a person can trust with its sensitive data to stay completely locally Did use ai to code for speeding and cutting labor. Its works on RTX 3080 system (this is an basic affordable setup not heavy ai machinery) which i want it to make it reliable…

Your Mac can run AI that holds its own against cloud models for the everyday stuff: chatting, making images, reading documents, transcribing voice. The hardware got there a while ago. The software to actually use it locally mostly didn't, so I built Off Grid. Download a model and it all runs on your machine. Ask it something on a flight with no wifi. Summarize a confidential document that never leaves your laptop. Run a hundred image generations in a loop and pay nothing, because it's your own GPU doing the work. Swap your paid dictation app for local Whisper. Talk through a coding problem…
