RegSQL vs SQLint

RegSQL is a web SQL workspace combining browser-local formatting with optional AI assistance. Formatting runs in a browser worker without an account or server round trip. It adjusts whitespace and casing while preserving query logic, aliases, and comments, and accepts multi-statement input up to 1 MB. Listed dialects are PostgreSQL, MySQL, MariaDB, SQLite, BigQuery, SQL Server, Snowflake, and Oracle PL/SQL. AI tools can generate SQL from a description, explain an existing query, or suggest a repair. Formatting may reveal parsing problems, but RegSQL does not connect to a database or verify tables, columns, permissions, data types, or runtime behavior. SQL, prompts, and schema text are sent to the AI provider only after Generate, Explain, or Repair is chosen. The Free plan is free, billed Forever, with unlimited local formatting and 20 AI requests monthly. Indie costs $8 a month or $72 billed yearly ($6/month).

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.
