SQLFluff vs SQLint

SQLFluff is an open-source, dialect-flexible SQL linter designed for ELT applications. It reports style and syntax issues, parses SQL without database access and can automatically fix many violations with one command. Documentation describes support for more than 25 dialects, including T-SQL, PostgreSQL, BigQuery and Snowflake, alongside more than 70 rules for style, structure and best practices. Jinja templating and dbt are supported, and CI/CD integration includes GitHub Actions output for pull-request annotations. SQLFluff is free under the MIT License and installs from PyPI with pip or another Python package manager. It does not execute SQL itself, but templating macros such as dbt's run_query may execute arbitrary SQL. The Jinja templater uses Jinja2 SandboxedEnvironment to limit unsafe code execution. The dbt templater requires the relevant adapter and sqlfluff-templater-dbt package; models accessing a database during compilation require database access. Community support includes documentation, GitHub, Slack and Stack Overflow.

SQLint is a free, MIT-licensed Python parser and linter for Standard SQL (BigQuery), intended for developers on Linux. It checks indentation, repeated spaces and blank lines, keyword casing, comma placement, bracket spacing, operator spacing, and join formatting. The `-f` option formats SQL, and automatic fixes are supported. Command-line use and Python imports for `parse`, `check`, and `format` are documented. The project also describes a configuration file, CI/CD integration, and Docker instructions for building and running the tool. Installation uses `pip install sqlint` or a repository clone. PyPI lists version 0.2.4, released October 22, 2019, with a source distribution and a platform-independent `py3-none-any` wheel. The package is classified as Alpha, and no free trial is listed because the package itself is free. The repository provides an Issues tracker for questions and reports. The documented SQL dialect is Standard SQL (BigQuery), with no third-party integrations listed on the opened page.
