# nodrix

> nodrix is an open-source, single-tenant IoT cloud that deploys to your own Cloudflare account. Hardware speaks plain HTTPS or WebSocket, telemetry streams to realtime drag-and-drop dashboards, automations run at the edge, and a clean read API exposes the data — with no broker, no servers, and your data never leaving your account.

## What it is
- Open-source (MIT) IoT backend for Cloudflare; first stable release (v1.0).
- Single-tenant: every deployment lives in the user's own Cloudflare account.
- One-click "Deploy to Cloudflare" — provisions Workers, Durable Objects, D1, R2, and KV.
- Devices send telemetry over plain HTTPS (POST /v1/telemetry) or a WebSocket (/v1/control/ws); variables auto-create on first sight. No MQTT broker and no SDK required — with an optional Arduino/ESP library that wraps the protocol.
- Realtime dashboards built from drag-and-drop widgets over hibernating WebSockets.
- Two-way control: toggles/sliders/buttons write values back to hardware.
- Edge automations: a visual flow builder — one or more triggers (variable thresholds, schedules, sunrise/sunset, custom events) branch through conditions into actions (set variables, call an integration over HTTP/email/chat like Slack/Telegram/Discord, or emit events).
- Clean read API: edge-cached latest state, time-series, and variable listings behind one bearer token.
- Optional MCP (Model Context Protocol) server — owner-gated, off by default. Lets Claude, Claude Code, ChatGPT, and any MCP-aware client read projects and (with an explicit toggle) drive automations. Bearer transport at /v1/mcp; OAuth at /v1/mcp/oauth.

### Comparisons & platform alternatives
- [Raspberry Pi Pico 2 W vs ESP32: which for a cloud IoT project?](https://nodrix.live/guides/raspberry-pi-pico-2-w-vs-esp32): An honest Pico 2 W vs ESP32 comparison for connected projects — where the Pico 2 W's newer silicon and clean MicroPython win, where the ESP32's wireless maturity and huge ecosystem win, and which to pick when the project reports to a cloud dashboard.
- [The best free IoT platforms for makers in 2026, ranked](https://nodrix.live/guides/best-free-iot-platforms): Every 'free' IoT platform caps something — devices, messages, retention, or all three. Here's an honest ranking of the free tiers makers actually use in 2026, what each one caps, and the one option where the free tier is Cloudflare's, not a vendor's.
- [nodrix vs Grafana + InfluxDB: the DIY IoT stack, weighed honestly](https://nodrix.live/guides/nodrix-vs-grafana-influxdb): Grafana with InfluxDB is the forum-default answer for IoT dashboards — and it's half an answer. Here's the honest comparison: what the DIY stack does better, what it quietly doesn't do at all, and what four self-hosted services really cost against one serverless deploy.
- [A Particle alternative you own — open-source, on your Cloudflare account](https://nodrix.live/guides/particle-alternative): Particle was acquired by Digi International in January 2026 and is being folded into an OEM business. For Wi-Fi makers weighing their options, nodrix is an open-source alternative you deploy to your own Cloudflare account — no subscription, no vendor cloud, plain HTTPS/WebSocket.
- [The open-source Adafruit IO alternative you host on your own Cloudflare account](https://nodrix.live/guides/adafruit-io-alternative): Looking for an Adafruit IO alternative without rate caps or data-retention limits? nodrix is open-source IoT you deploy to your own Cloudflare account — plain HTTPS/WebSocket, dashboards, automations, and a read API, with your telemetry in your own tenancy.

- [Home Assistant vs nodrix: local smart-home hub or your own cloud IoT backend?](https://nodrix.live/guides/home-assistant-vs-nodrix): Home Assistant vs nodrix — they solve different problems. HA is a local home-automation hub for off-the-shelf devices; nodrix is an open-source cloud IoT backend you deploy to your own Cloudflare for custom hardware, remote dashboards, and a read API. Here's how to choose, and how they pair.
- [A lightweight ThingsBoard alternative for makers — zero servers to run](https://nodrix.live/guides/thingsboard-alternative): ThingsBoard is powerful but heavy to self-host. nodrix is an open-source alternative that one-click deploys to your own Cloudflare account — no Java, Postgres, broker, or VM to operate, with dashboards, edge automations, and a read API.

### Hardware & board guides
- [ESP32-C3 vs ESP8266: the upgrade question, answered honestly](https://nodrix.live/guides/esp32-c3-vs-esp8266): ESP32 vs ESP8266 in 2026, at the budget end: the ESP32-C3 is the 8266's designated successor at nearly the same price, with the RAM headroom that makes TLS comfortable instead of a squeeze. When to switch, when the old board is still the right call, where the wider ESP32 family fits, and what changes in firmware.
- [ESP32-C6 for makers: what the new radios change, and what they don't](https://nodrix.live/guides/esp32-c6-for-makers): The ESP32-C6 packs Wi-Fi 6, BLE, and an 802.15.4 radio for Thread and Zigbee into a $5 board — the ESP32 line's ticket into Matter. Here's what that actually means for a maker project today, the radio fine print nobody leads with, and why your cloud firmware doesn't change at all.
- [ESP32 battery life: deep sleep + cloud telemetry that lasts months](https://nodrix.live/guides/esp32-deep-sleep-battery): Make a battery-powered ESP32 sensor run for months while still reporting to the cloud. Deep sleep structure, RTC-memory Wi-Fi caching, a real power budget, and the dev-board traps that quietly kill battery life.
- [Connect an ESP32 to the cloud over HTTPS — a complete guide (no MQTT broker)](https://nodrix.live/guides/esp32-https-cloud): Push ESP32 sensor data to the cloud and receive commands back with the nodrix Arduino library — plain HTTPS underneath, no MQTT broker. Telemetry, control writes, and months of battery life with deep sleep.
- [Receive commands on an ESP32 from the cloud (the downlink, in depth)](https://nodrix.live/guides/esp32-receive-commands): How to get data back to an ESP32: handle control writes with the nodrix Arduino library over an always-on WebSocket, or poll on each wake for battery devices. The downlink most IoT tutorials skip.
- [ESP8266 to the cloud over HTTPS — a live dashboard with no broker](https://nodrix.live/guides/esp8266-iot-dashboard): Push ESP8266 sensor data to a cloud dashboard with the nodrix Arduino library — BearSSL under the hood on the 8266's tight RAM, no MQTT broker, control writes back to the board, and the deep-sleep wiring that makes a battery sensor last.
- [Raspberry Pi Pico W to the cloud with MicroPython — a live dashboard](https://nodrix.live/guides/raspberry-pi-pico-w-iot-dashboard): Send Raspberry Pi Pico W sensor data to a cloud dashboard with MicroPython over HTTPS — no broker. Full code for telemetry with urequests, commands back to the board, the onboard temperature sensor, and an honest note on Pico W TLS.

### Concepts & how-tos
- [MQTT vs HTTP for IoT: an honest comparison for makers](https://nodrix.live/guides/mqtt-vs-http-iot): Most MQTT-vs-HTTP comparisons are written by broker vendors, and it shows. Here's the maker's version: where MQTT genuinely wins, where the famous overhead numbers mislead, why WebSocket is the missing third option, and how to actually choose for an ESP32-class project.
- [Open-source IoT dashboards in 2026: what actually works for makers](https://nodrix.live/guides/open-source-iot-dashboard): Most 'best open-source IoT platform' lists are written for factories, not makers. Here's the maker's-eye view: what an IoT dashboard actually needs to do, which open-source options genuinely deliver it, what each one costs to operate, and when a serverless deploy beats them all.
- [How to update a nodrix instance: one rebuild, nothing to migrate](https://nodrix.live/guides/update-nodrix): Updating a self-hosted nodrix deployment is one button, not a migration project: the app tells you when a release is out, one rebuild pulls it in, and schema changes apply themselves. Here's exactly how the update path works, how to check your version, and how to roll back.
- [How to deploy nodrix to Cloudflare: a free-tier setup guide](https://nodrix.live/guides/deploy-nodrix-cloudflare): Deploy nodrix into your own Cloudflare account in a few minutes. Create a free account, run the one-click deploy, and understand the one step that trips people up — why Cloudflare asks for a card even though nodrix runs entirely on the free plan.
