1. Introduction

SQL playgrounds, also known as online SQL compilers or SQL editors, are powerful tools that enable developers to test SQL queries and experiment with database management commands without the need for local database setups. These tools are especially helpful for beginners, educators, and experienced developers who need a quick and easy way to execute SQL commands.

In this article, we will compare 10 of the top SQL playground tools and online SQL compilers, highlighting their features, user experiences, and performance. Let’s dive into why RunSQL takes the top spot and how it compares to other tools available today.

2. What is an SQL Playground or Online SQL Compiler, and Why Choose One?

An SQL Playground or Online SQL Compiler is a web-based tool that allows developers to write, test, and execute SQL queries directly in their browser, without the need for setting up a local database. These tools provide a sandbox environment for experimenting with SQL commands, making them ideal for learning, testing, and debugging.

Why Choose an SQL Playground Tool?

There are several reasons why developers and learners choose SQL playgrounds over local setups:

• No Local Setup Required: You can start testing SQL queries instantly without needing to install or configure database software.
• Cross-Platform Testing: Many SQL playgrounds support multiple database engines (e.g., MySQL, PostgreSQL, SQLite), enabling users to test queries across different SQL dialects with ease.
• Ease of Collaboration: Share SQL queries and results with others through simple URLs, making debugging and teamwork more efficient.
• Immediate Feedback: Execute queries and see results in real-time, which speeds up learning and helps developers identify issues in their queries faster.
• Learning and Experimentation: Ideal for beginners, students, and those looking to refine their SQL skills without the risk of affecting production data.

SQL playgrounds provide an accessible and convenient way to practice SQL, whether you’re learning the basics or testing complex queries. They are particularly useful when you need to quickly validate SQL syntax or share SQL scripts with others.

3. Top 10 SQL Playground Tools

3.1 RunSQL

RunSQL leads the pack with its modern, user-friendly interface and cloud-based execution, ensuring fast and reliable performance. Key features include:

• Supports PostgreSQL, MySQL, and SQL Server.
• DBML schema creation, making it easier to define database structures without writing SQL for CREATE TABLE.
• Excel-like data entry to populate test data, eliminating the need for repetitive INSERT commands.
• Direct link sharing for seamless collaboration, where users can share both their queries and datasets.
• AI-generated sample data (coming soon) to speed up testing and data population.

Best for: Developers, teams, and SQL learners who want an easy-to-use, collaborative SQL testing environment.

3.2 SQL Fiddle

SQL Fiddle is one of the most popular and long-standing SQL playgrounds. While it offers multi-database support (MySQL, PostgreSQL, SQLite, and Oracle), there are some limitations:

• Manual schema and data setup.
• Inconsistent performance during heavy queries.
• Basic collaboration tools (only query sharing).

Best for: Quick syntax validation and sharing queries, though less ideal for complex testing or collaborative workflows.

3.3 DB Fiddle

DB Fiddle offers a similar feature set to SQL Fiddle but with enhanced performance for certain databases. It supports multiple dialects (MySQL, PostgreSQL, SQLite, and SQL Server) and enables users to share queries via unique links. However, the lack of an intuitive data entry system can slow down testing for users.

Best for: Developers looking for multi-database support with basic testing features.

3.4 DB-Fiddle

Another alternative, DB-Fiddle (similar to DB Fiddle), provides support for MySQL, PostgreSQL, SQLite, and SQL Server. Key features:

• Allows quick query sharing.
• Some performance issues, especially with complex queries.
• Limited schema management options.

Best for: Quick, basic queries and testing across multiple databases.

3.5 W3Schools SQL TryIt Editor

W3Schools’ SQL TryIt Editor is a great tool for beginners. It’s simple to use and doesn’t require any setup, but it only supports basic queries on a small, predefined database.

Best for: Beginner SQL learners who want to test simple queries.

3.6 Programiz SQL Online Compiler

Programiz offers a clean interface that supports basic SQL operations. It provides real-time query execution but lacks advanced features like schema management or multi-database support.

Best for: Beginner SQL learners or quick testing of basic SQL queries.

3.7 MyCompiler.io SQL Editor

MyCompiler.io is a versatile online compiler that supports multiple programming languages, including SQL. It supports MySQL, PostgreSQL, and SQLite, but lacks the dedicated SQL-focused features that some other platforms offer.

Best for: Multi-language developers who occasionally need to work with SQL.

3.8 SQLPad

SQLPad is an open-source SQL editor that supports multiple databases, including MySQL, PostgreSQL, and SQL Server. Its key features include:

• Query history and saved queries.
• Collaborative query editing for teams.
• Schema visualization tools.

Best for: Database administrators and teams working on large SQL projects.

3.9 SQLiteOnline

SQLiteOnline is an excellent tool for working with SQLite databases. It provides a web-based interface for managing SQLite databases and running queries but lacks support for other database types.

Best for: Developers working with SQLite databases.

3.10 SQLShack

SQLShack offers free online SQL editors with support for SQL Server, MySQL, and PostgreSQL. While it’s not as well-known as other tools, it’s a solid option for users seeking a simple SQL editor for quick tests.

Best for: Users testing SQL Server queries or simple cross-database testing.
