Blynk

Blynk is a low-code / no-code IoT software platform that helps companies prototype, deploy, and remotely manage connected devices and applications across consumer and commercial markets. The platform combines four components — Blynk.Console (web dashboard), Blynk.Apps (white-labeled iOS and Android apps), Blynk.Edgent (device-side connection library), and Blynk.Cloud (managed backend) — into a full-stack offering that removes the need to build custom IoT infrastructure. Developers can build interactive mobile and web dashboards with a drag-and-drop builder, connect hardware over Wi-Fi, Cellular, LoRaWAN, Ethernet, or satellite, and operate fleets with provisioning, OTA firmware updates, multi-tenancy, automations, webhooks, and SOC 2 cloud infrastructure. Commercial customers use Blynk for branded consumer products, industrial monitoring, agriculture, energy and HVAC, smart cities, and smart buildings, with more than 5,000 companies and 1M+ developers on the platform. Blynk exposes two HTTPS REST APIs — the Device HTTPS API for telemetry and command exchange from individual hardware units, and the Platform HTTPS API (Enterprise plan) for full programmatic CRUD over devices, users, organizations, templates, automations, webhooks, and tags using OAuth2 client-credential authentication.

Blynk publishes 3 APIs on the APIs.io network. Tagged areas include IoT, Internet of Things, No-Code, Low-Code, and Connected Devices.

Blynk’s developer surface includes developer portal, documentation, getting-started guide, signup flow, developer console, pricing, engineering blog, and 35 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 75 points between them, because both conditional facets apply and carry 25 points together. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/blynk: open an issue to ask a question, or submit a pull request to add artifacts.
