Our verdict on IoTPlotter

IoTPlotter is a free web-based service for collecting, storing, and graphing data from internet-connected devices. It is aimed at makers and other users who need to compare current measurements with older readings over time. The service combines responsive graphs, public feeds, historical datapoints with timestamps, and APIs for sending and reading numerical data. Its web and API access make it suitable for IoT projects that need a straightforward place to retain and visualize measurements.

The product’s main strength is its focus on long-term IoT data. A Free plan includes long-term data history, responsive graphs, API access, and public feeds. The JSON HTTP API supports writing and reading data, while the CSV HTTP API provides the same broad data movement options in a tabular format. Feed-specific API keys help separate access between feeds, and timestamped datapoints support historical comparisons. This combination fits device telemetry projects that need durable records and programmatic access without a paid tier.

IoTPlotter is narrower than general-purpose data visualization software. It centers on IoT feeds and measurement charts rather than dashboards, integrations, embedding, or a wider set of visualization features. The service is also presented as a beta product, which may matter to teams seeking a more established platform for critical reporting. Choose IoTPlotter when free, web-based IoT graphing, public feeds, and JSON or CSV access are the priority. Choose an alternative when your project requires dashboard composition, broader integrations, embedded visualizations, or visualization beyond device measurements.
