Natural Language → SQL
Translate human-readable queries (like “show me all users whose email starts with user”) into valid SQL statements automatically.

Database Dialect Awareness
Supports multiple database clients such as MySQL, PostgreSQL, SQLite, MSSQL, etc., by integrating with Knex.js. It knows how to generate SQL that matches the specific dialect.

Multiple LLM Providers Supported
Works with Groq, OpenAI, Gemini, and potentially other LLMs. You can configure which LLM provider and model to use via your .env file.

Strong Validation & Safety
Built-in schema awareness + query validation helps ensure that the generated SQL is syntactically correct and safe for execution.

Extensible and Configurable
Easily plug into your existing stack. You define the database connection & LLM settings, and QueryCrafter handles the rest.

Execute Queries Directly
Not just for generating SQL — you can run queries directly from QueryCrafter, getting both the SQL string and the resulting data back.

Lightweight & Modern
Written in TypeScript / JavaScript and designed to be minimal yet powerful. Use it in your backend or on Node.js microservices.
