Fast, zero config web endpoint change monitor

Overview

web monitor

fast, zero config web endpoint change monitor. for comparing responses, a selected list of http headers and the full response body is stored on a local key/value store file. no configuration needed.

  • to increase network throughput, a --worker flag allows to set the concurrency when monitoring.
  • endpoints returning a javascript content type will be beautified by default.
  • using --headersOnly when adding a URL allows to only monitor response headers.
