Parser vs. Analysis Comparison

The Payload Parser was created to handle raw payloads sent by devices to extract measured variables or execute simple operations. The Analysis feature is more capable: it includes access to Devices and external services, but there is a cost to run analyses. Payload Parser uses a simple JavaScript engine developed by TagoIO to be easy, lightweight, and free.

Notes

• Payload Parser is intended for lightweight parsing and basic operations directly on incoming device payloads.
• Analysis offers broader capabilities (access to devices, external services, larger code size, and more advanced error handling), suitable for more complex workflows.
• Use the Payload Parser for simple, free parsing needs and Analysis when you need external integration, advanced JavaScript features, or persistence across executions.
