Trystero is a TypeScript library (2,761 stars, just updated today) for building multiplayer webapps where browsers discover and communicate with each other peer-to-peer via WebRTC, with peer discovery handled by one of seven “strategies”: BitTorrent, Nostr, MQTT, IPFS, Supabase, Firebase, or a self-hosted WebSocket relay. It’s the kind of elegant abstraction that makes conference talks about decentralization sing — drop a line of code, get a room, add video, boom, you’ve built Figma on top of a DHT swarm and nobody deployed anything. Trending right now because P2P is having another cultural moment and because, genuinely, the engineering is clean.
But here’s the thing about Trystero: it solves a problem for people building multiplayer webapps. Jordan’s stack solves a problem for people automating a house. These are not the same problem, and Trystero has exactly zero contact points with anything running on nova-core or a Aqara sensor or the Hue bridge.
Let me walk you through where this doesn’t fit. Trystero is built for browsers talking to browsers. That’s the core value prop: open a web app in two browser windows, you’re immediately in a p2p room with end-to-end encryption, no server, no account, no deploy. Fine! For collaborative whiteboards, real-time multiplayer drawing apps, shared gaming experiences where you don’t want to pay for a server — it’s genuinely elegant. The API is nice. The chunking and throttling abstractions are useful. React hooks are built in. I’d recommend it to someone building that exact thing.
Jordan is not building that exact thing. She’s running Home Assistant on a Mac Studio, coordinating 100+ Zigbee/Z-Wave/Matter devices through local-only protocols, serving Grafana dashboards with real-time energy data pulled from PostgreSQL, and making sure 15 cameras feed presence detection to automations that turn lights on before she walks through the door. The last time I checked, she wasn’t trying to build a collaborative real-time whiteboard for her bedroom switches. She wants the switches to turn on when she walks in the room. We’ve already got that solved.
Now, zoom into Trystero’s seven strategies and pretend for a second that the use case made sense. Start from the top: Firebase and Supabase are cloud services. They require accounts, authentication, they phone home by design, they lock you into managed infrastructure. For a home-automation context where local-first and cloud-optional are non-negotiable? Hard pass. Docked. Moving on. Nostr is a decentralized social protocol that runs on public relays. It’s not local. Privacy implications are spicy. Not a vehicle for home-automation state. BitTorrent and IPFS use public DHTs for peer discovery by default (you can configure private DHTs, but the repo examples don’t, and Trystero’s abstractions don’t make it easy). Broadcasting your home-automation state across the public BitTorrent DHT so strangers can theoretically discover your room ID? That’s not even a bug, that’s a feature of the library, and it’s a hard no for anything touching your house. Self-hosted WebSocket relay — okay, this one is local-first and makes sense. But now you’re just running a WebSocket relay and using Trystero’s P2P layer on top of it, which means you’re paying the cost of Trystero’s complexity and gaining… what? A JavaScript library for multi-browser real-time state sync? You already have that: Home Assistant’s WebSocket API, Grafana, or a simple SSE feed. MQTT is the one strategy that actually fits the local-first mandate, but Trystero’s MQTT support is for browsers discovering each other and then talking peer-to-peer; it’s not a drop-in replacement for the MQTT ecosystem already handling Zigbee gateways and sensor ingestion.
The deeper point: Trystero solves peer discovery for browsers. Your home doesn’t need peer discovery between browsers; it needs a coordinator. Home Assistant is the coordinator. It’s sitting on 192.168.1.6 right now, listening for Zigbee events, running automations, holding entity state, serving the UI. You don’t want the Hue bridge and a Z-Wave stick and an ESPHome device discovering each other and sharing state via WebRTC. You want them reporting to Home Assistant, which is authoritative, consistent, and local-only. Add Trystero and you’re asking: why? Do you need multiple HA instances coordinating? No. Do you need browsers collaboratively editing your living room state? No. Do you need P2P video chat? You can use Janus or grab a video conferencing app like literally any human on Earth.
There’s a possible STEAL angle here — the chunking and throttling abstractions Trystero uses for large binary data transfers could theoretically inspire smarter camera stream handling in a local dashboard, or the encryption layer could be useful for securing edge-to-edge telemetry. But you don’t need the library for that; you just grep the source and steal the algorithm. The library itself brings no value to the stack.
Here’s the roast: Trystero is what you build when you want to give decentralization a try and you’re building FOR the web. Jordan already has decentralization where it matters — Zigbee mesh, Z-Wave mesh, cameras reporting locally — and centralization where it matters — Home Assistant as the single point of automation truth. Layering a P2P browser framework on top of that is like adding a second kitchen to a house and asking both kitchens to run different dinner plans: technically possible, functionally insane, someone’s going to get hungry.
Pass. It’s smart infrastructure for the wrong problem. Keep shipping and let Little Mister keep his house coordinator running without inventing new failure modes.
Trystero is not for this house. It’s for people who want to build Figma. Move on.
