RegSQL vs SQL Enlight

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).

SQL Enlight is a static analysis and refactoring tool for SQL Server and T-SQL. It examines code and databases for defects and supports server health monitoring, diagnosis, and performance tuning. Developers can validate syntax, run automated reviews, and apply automatic fixes to some code and database issues. Formatting, script summaries, and outlines help make large scripts easier to work with; sections can also be extracted into stored procedures or functions. Developers and database administrators can create custom analysis rules with XPath and XSLT. The tool integrates with SQL Server Management Studio and Visual Studio, and supports build workflows through Team Foundation Server check-in policies, MSBuild tasks, a command-line interface, and an Automation API. Its Azure DevOps extension supports build analysis, quality gates, reports, and pull-request checks and comments; a SonarQube plugin adds T-SQL issues, measures, rules, and quality-gate integration. SQL Enlight supports SQL Server 2005 through 2022, including Azure SQL Database. The paid product has a 14-day evaluation period. Licenses include email support, updates, and documentation access.
