better-exceptions
Pretty and helpful exceptions, automatically
Decision gist · record as of 2026-08-14
Yes, if you do development work in Python and want better exception visibility without code changes. The low install friction, active maintenance, and zero known vulnerabilities make it a safe addition to a development environment. Not necessary for production unless you explicitly want formatted exception logging, in which case be careful to disable the environment variable in production.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires the BETTER_EXCEPTIONS environment variable to be set; without it, exceptions display normally.
- Low install friction with a single lightweight dependency (colorama).
- Actively maintained as of July 2026, though the latest release was in January 2021.

What it is and what it does
better-exceptions hooks into Python's exception system to display tracebacks with syntax highlighting and local variable values inline, making it easier to understand what went wrong at a glance. It works by setting an environment variable and is designed to be transparent—once activated, all exceptions in your Python process are automatically formatted without code changes. The package depends only on colorama for terminal color support.
You can use it in regular scripts, the Python REPL (via `python -m better_exceptions`), unittest test runners (with a monkey patch), or Django applications (via middleware). Advanced usage allows disabling value truncation. The package is intended for development and debugging; the documentation explicitly warns against leaving the environment variable set in production to avoid leaking sensitive data in logs.
Use it for
- Interactive debugging in the Python REPL to see local variables and syntax-highlighted code context.
- Development workflows where you want richer exception output without modifying application code.
- Django projects where middleware integration provides formatted exceptions across the entire request lifecycle.
- Unit test debugging to see better-formatted assertion failures and error context.
