About:
fblog is a command-line utility designed to parse and colorize JSON-formatted log streams, making them human-readable. It transforms verbose, single-line JSON logs into a structured, multi-line format, highlighting key fields like timestamps, log levels, and messages. This tool significantly improves the debugging and monitoring experience for developers working with JSON-based logging systems.
Key Features:
  • Automatic colorization of log levels and key fields
  • Support for custom log format patterns
  • Efficient streaming of large log files
  • Handles both pretty-printed and minified JSON input
Use Cases:
  • Parsing JSON logs from cloud services or containerized applications
  • Real-time log monitoring during development or debugging
  • Filtering and formatting log files for better readability in terminals
Alternatives:
  • jq – jq is a powerful general-purpose JSON processor, while fblog is specialized for log viewing with built-in formatting and coloring.
  • gron – gron converts JSON into discrete JavaScript assignments, useful for scripting, whereas fblog focuses on human-readable log output.
