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 46 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/adafruit-io: open an issue to ask a question, or submit a pull request to add artifacts.

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.
