The record

Purpose: sql-tools is a free, browser-based toolkit for engineers working with Snowflake, BigQuery, Databricks, PostgreSQL, MySQL, and SQL Server.
SQL formatting: The formatter supports six SQL dialects, configurable indentation and keyword case, and runs in the browser.
Other tools: The site lists SQL escaping and unescaping, SQL minification, and an AI-powered SQL dialect translator among its tools.
Translation limit: The translator allows 30 translations per IP per hour, and cached repeat translations do not count against the limit.
Translation provider: SQL translations are handled via OpenRouter.
Translation retention: Identical translator queries are cached for 24 hours using a SHA-256 hash of normalized input; the page says query logs are not kept.
Client-side processing: The maker says every tool except the AI dialect translator runs in the browser, with no accounts, uploads, or tracking of queries.
Privacy policy: The privacy policy says information entered is used to provide the requested feature and advises against submitting confidential, sensitive, or proprietary information unless comfortable with that processing.
Security: The privacy policy says the service uses reasonable safeguards but cannot guarantee complete security.
Support: The About page provides [email protected] for feedback.
Translation caveat: The maker says translations may be partial for complex stored procedures and warehouse-specific UDFs, and advises reviewing and testing output before production use.
Planned features: The ERD generator and AI query optimizer are marked coming soon on the homepage.
