As answered by people managing LeetCode and SqlInt.
SqlInt's answer:
SQLint is primarily built for students, aspiring developers, developers improving their SQL skills, and anyone preparing for technical interviews that involve SQL.
SqlInt's answer:
No major customers yet- SQLint is currently open to individual learners and developers.
SqlInt's answer:
SQLint focuses on learning by doing. Users can practice SQL queries, prepare for interviews, and solve interactive puzzles in one place, making SQL practice more hands-on and engaging than simply following tutorials or reading documentation.
SqlInt's answer:
SQLint combines practical SQL practice with interactive puzzles, giving learners a more engaging way to build real query-writing and problem-solving skills. Instead of only learning SQL concepts, users learn by writing, experimenting, and solving challenges.
SqlInt's answer:
SQLint started with a simple idea: SQL is best learned by actually writing and solving queries. Instead of making learning purely theoretical, the goal was to create a practical and interactive place where people can practice SQL, make mistakes, solve problems, and improve their skills.
SqlInt's answer:
Only list technologies you're actually using. If your stack is: Next.js, React, TypeScript, and Supabase
