Pino is a very fast, low-overhead JSON logger for Node.js (and Bare/Pear runtimes), with child loggers, redaction, and worker-thread transports. Its companion pino-pretty formats log lines for human-readable development output.

Use cases

• add structured JSON logging to a Node.js service
• log with minimal performance overhead in production
• pretty-print logs during development
• attach contextual properties with child loggers
• redact sensitive fields from logs
• integrate logging with Express, Fastify, Koa, or Hapi

When to choose

• you need high-throughput, low-overhead logging in Node.js
• you want structured JSON logs for log aggregation pipelines
• you use Fastify or other Node web frameworks and want first-class logging

When to avoid

• you need human-readable logs by default without a prettifier transport
• you are not on Node.js or a compatible runtime
• you need built-in log shipping to external services without transports
