Adafruit IO

Adafruit IO is a cloud Internet of Things platform from Adafruit Industries built for makers, hobbyists, students, and STEM educators. It provides feed-based time-series storage, drag-and-drop dashboards with 20+ visualization block types, actions/triggers for SMS/voice/email/webhook notifications, built-in services (time, weather, randomizer, air quality), and a complete REST + MQTT API surface for Adafruit Feather and Metro boards, ESP32 / ESP8266 / Pico microcontrollers, Raspberry Pi, and any other HTTP- or MQTT-capable hardware. First-class Arduino, CircuitPython, and Python client libraries plus the no-code Wippersnapper firmware make it the easiest way for hobbyists to get their projects onto the Internet of Things.

Adafruit IO publishes 11 APIs on the APIs.io network, including Activities API, Blocks API, Dashboards API, and 8 more. Tagged areas include IoT, Internet of Things, MQTT, Maker, and Hobbyist.

The Adafruit IO catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Adafruit IO’s developer surface includes authentication, developer portal, documentation, getting-started guide, engineering blog, changelog, signup flow, and 45 more developer resources.

    QoS 0 and QoS 1 (QoS 2 not supported); MQTT retain flag is not honored — use the /get topic modifier to fetch the last
    value of a feed instead. Topic structure includes feed topics ({username}/feeds/{key}), compact aliases ({username}/f/{key}),
    JSON/CSV suffixes, group topics ({username}/groups/{key}), throttle ({username}/throttle), and errors ({username}/errors).
    Wildcard subscriptions with `+` and `#` are supported for feed discovery.

  - Feed-centric time-series datastore for IoT sensor and actuator values
  - Drag-and-drop dashboards with 20+ block types (gauges, charts, toggles, sliders, maps, color pickers, image, indicators,
    text, number pad, selector, etc.)
  - Feed groups for organizing related feeds and batch group writes
  - Actions/Triggers — reactive triggers (threshold, equal, change) and scheduled actions (every N minutes, hours, daily,
    weekly)
  - Webhook-in endpoints (standard, raw, notify) for ingesting data without an API key

  - Adafruit IO Wippersnapper firmware — no-code MQTT firmware for ESP32, ESP8266, and Pico
  - First-class Arduino and CircuitPython client libraries
  - Public feed sharing and embeddable dashboards
  - Permission/ACL primitive for fine-grained sharing of feeds, dashboards, and groups
  - Personal access tokens for scoped, revocable credentials separate from the main API key
  - Account activities log with type filtering
  - Throttle topic to monitor rate-limit pressure programmatically
  - Single comprehensive Swagger 2.0 / OpenAPI spec published in adafruit/io-api on GitHub
  - IFTTT and Zapier integrations for cross-service automation
  - Optimized for makers, hobbyists, and STEM education with Adafruit Feather, Metro, and Raspberry Pi hardware

description: Adafruit IO is a cloud Internet of Things platform from Adafruit Industries built for makers, hobbyists, students,
  and STEM educators. It provides feed-based time-series storage, drag-and-drop dashboards with 20+ visualization block types,
  actions/triggers for SMS/voice/email/webhook notifications, built-in services (time, weather, randomizer, air quality),
  and a complete REST + MQTT API surface for Adafruit Feather and Metro boards, ESP32 / ESP8266 / Pico microcontrollers, Raspberry
  Pi, and any other HTTP- or MQTT-capable hardware. First-class Arduino, CircuitPython, and Python client libraries plus the
  no-code Wippersnapper firmware make it the easiest way for hobbyists to get their projects onto the Internet of Things.
