Offline Protocol

Every machine waits for a signal. When it breaks, everything goes blind. We started Offline Protocol by keeping people connected when networks failed. Today, that same technology runs on hundreds of thousands of devices worldwide. Now we're taking it further: resilient coordination for physical systems. Machines, people and AI agents that keep working together over whatever path remains. Where we are today: → 350,000+ devices across 140+ countries → Nearly 20,000 new accounts in August alone → 11,500+ local networks active this month → 60,000+ SDK downloads → 440,000+ location proofs received in the last 30 days → Zero paid acquisition Earlier this year, we closed a new round led by @DraperVC to turn our consumer scale into a rapidly growing enterprise business. Over the past month, we've begun working with partners including a global wind-energy manufacturer, an agricultural IoT provider, a fleet telematics platform, a physical AI operating system, and a data streaming platform, alongside teams in aerospace and satellite systems, embedded silicon and consumer wearables. Our pipeline also spans maritime and industrial monitoring, equipment custody, secure device identity, airline catering and restaurant operations. Wherever machines operate, Offline Protocol coordinates. Learn more at offlineprotocol.com

Offline Protocol SDK v0.33.0 is out. Resends and delivery receipts now travel as far as the first copy did, across every hop of a phone mesh. In a simulated crowd of forty phones every delivery receipt comes back, and on a two-hop chain of phones, receipts slower than five seconds fell from 118 of 200 to 15. React Native now requests the Android Bluetooth and Wi-Fi permissions the mesh needs in one call. Development builds point out integration mistakes, such as a username passed where a device address belongs or a send before start(). Release builds stay silent. No API is removed. What's new: offlineprotocol.com/blog/sdk… npm, PyPI and every binding: github.com/Offline-Protocol/…

Group hikes split up right where the signal drops. @aditipolkam built Muster: phones in the group form a Bluetooth mesh, share live positions, and guide everyone to the leader's meeting point with a compass. No server, no account. Built on our mesh SDK: github.com/aditipolkam/muste…

Autonomous operations for robot fleets, no internet required. @mizanxali built MeshRover at @ETHGlobal Mumbai, and it keeps running when the network is gone. Every robot doubles as a relay. Camera frames travel robot to robot over an Offline Protocol mesh to a base, where a @0G_labs AI model running in a TEE makes the call, and the decision comes back over the same mesh. No towers or Wi-Fi needed. If an answer doesn't arrive in time, the robot stops safely. Entering a restricted zone needs a human to sign off with @worldnetwork ID, and every robot and operator has a role on @ensdomains v2. A full control loop running over the mesh. One of the many use cases where our stack can enable seamless operations.

Offline Protocol SDK v0.32.0 is out. Service subscriptions: a device subscribes to a service on another device and gets every update over the mesh, with no server and no internet. Updates are sealed end to end, or not sent at all. Available in the browser engine, React Native, Flutter and Python, and every binding is regenerated. Bluetooth LE links now stay up with the app in the background or the screen off, and an Android link recovers by itself when the app on the other phone restarts. New C# bindings over the C API: typed config, storage, events and transport callbacks. npm, PyPI and every binding: github.com/Offline-Protocol/…

Offline Protocol joins Zebra Technologies' PartnerConnect program. Zebra's rugged handhelds, scanners and wearables run the world's warehouses, delivery routes, yards and store floors. Those are exactly the places where Wi-Fi ends at the dock door and cellular drops behind concrete and steel. Offline Protocol gives them a network of their own. Devices sync records, message and hand off work directly over Bluetooth and Wi-Fi Direct, relay across an entire site, and reconcile with your systems the moment any device gets a link. Scans, pick lists, check-ins and proof of delivery keep moving through outages, dead zones and network failures. Through PartnerConnect we're bringing offline-first operations to Zebra's resellers, integrators and the frontline teams that run on Zebra every day.

Check out this demo for a Splitwise-style app to manage group expenses, completely offline. There are infinite ways to implement our infrastructure across any industry, all you need is some curiosity. We want to support developers building on our SDK, keep sharing your ideas!

"A bank is solvent until everyone wants their money on the same morning. A cell network works until something happens that is worth telling someone about." @sxtvik shares his thoughts on why phones stop working at crowded events, and what it says about the way we build networks.

It's been a hard few weeks for security, with breaches and leaked credentials affecting a lot of people. It's a reminder of why we keep building systems that don't depend on a single point that can fail. Our weekly newsletter by @chai_really rounds up the news, and what our team shipped this month: → Bluetooth payments for the Zcash community by @sxtvik, which complete even with both phones in airplane mode → Radius by @mizanxali: walk into a room and your phone shows who nearby is worth meeting → A smart hub by @bahdotsh that runs your home's devices with no internet Plus, we'll be at Devcon in Mumbai, and we look forward to seeing you there!

We’ve joined NVIDIA Inception, @nvidia's program for startups building with AI 🤖 At Offline Protocol, we have spent the past year experimenting and making multiple breakthroughs in on-device intelligence and federated training across heterogenous devices. We are now combining this work with our existing stack which lets phones, machines, and edge devices find each other and work together directly, with no internet or cloud in between. This unification provides a shared intelligence layer on top of our existing coordination layer to enable a brand new category of hardware and software applications. Inception has already given us access to NVIDIA’s partners who are helping us with product validation, along with developer tools, technical training and a flourishing enterprise network as we grow. Stay tuned for more news about our intelligence work.

We were named Crate of the Week! 🦀 'This Week in Rust' is the weekly newsletter of the Rust programming community, and every issue spotlights one open-source project. This week, it's ours. Our Rust engine inside the Offline Protocol SDK enables phones and other devices to find each other nearby and talk directly, with no internet needed. Thanks to everyone building on our stack! this-week-in-rust.org/blog/2…
