## What it is
SQLFluff is a dialect-flexible, configurable SQL linter and auto-formatter for Python. It supports many SQL dialects (BigQuery, Snowflake, Postgres, etc.), Jinja templating and dbt, and can auto-fix most linting errors.

## Use cases
- lint sql files for style and syntax errors
- auto-format sql queries consistently across a team
- lint dbt models with jinja templating
- enforce sql style rules in ci pipelines
- check sql syntax for a specific dialect like snowflake or bigquery without a database
- fix sql indentation and keyword casing automatically

## When to choose
- you need a configurable SQL linter supporting many dialects and templated code
- your team wants automated SQL formatting and style enforcement in CI
- you work with dbt or Jinja-templated SQL in ELT workflows

## When to avoid
- you need a full SQL parser or query engine rather than a linter
- you need runtime SQL validation against a live database
- your SQL dialect is unsupported or heavily non-standard
