*structlog* is *the* production-ready logging solution for Python:

- **Simple**: Everything is about **functions** that take and return **dictionaries** – all hidden behind **familiar APIs**.
- **Powerful**: Functions and dictionaries aren’t just simple but also powerful.
  *structlog* leaves *you* in control.
- **Fast**: *structlog* is not hamstrung by designs of yore.
  Its flexibility comes not at the price of performance.

Thanks to its flexible design, *you* choose whether you want *structlog* to take care of the **output** of your log entries or whether you prefer to **forward** them to an existing logging system like the standard library's `logging` module.

The output format is just as flexible and *structlog* comes with support for JSON, [*logfmt*](https://brandur.org/logfmt), as well as pretty console output out-of-the-box:

*structlog* has been successfully used in production at every scale since **2013**, while embracing cutting-edge technologies like *asyncio*, context variables, or type hints as they emerged.
Its paradigms proved influential enough to [help design](https://twitter.com/sirupsen/status/638330548361019392) structured logging [packages across ecosystems](https://github.com/sirupsen/logrus).

The idea of bound loggers is inspired by previous work by [Jean-Paul Calderone](https://github.com/exarkun) and [David Reid](https://github.com/dreid).

The development is kindly supported by my employer [Variomedia AG](https://www.variomedia.de/), *structlog*’s [Tidelift subscribers](https://tidelift.com/?utm_source=lifter&utm_medium=referral&utm_campaign=hynek), and all my amazing [GitHub Sponsors](https://github.com/sponsors/hynek).
