Free Online MySQL Compiler

A free online MySQL editor and compiler. Write SQL, press Run — your queries execute against a real MySQL 8.0 database instantly. No signup, no install, no waiting.

Real MySQL 8.0

Not a simulation. Each session gets its own isolated database on a live MySQL 8.0 server.

Zero setup

Open the page, start writing. Your database is ready in under a second — no account needed.

Work persists locally

Your SQL tabs are saved in your browser. When you return, your queries are right where you left them.

Auto-cleanup

Sessions expire after 60 minutes and the database is dropped. No data left behind.

What you can run

Full CREATE TABLE, INSERT, SELECT, JOIN, UPDATE, DELETE, DROP, and ALTER — anything that runs inside a single scoped database. Treat it as a free online MySQL database for learning MySQL syntax, testing a query before running it in production, prototyping a schema, or working through SQL exercises.

Keyboard shortcuts

  • Ctrl + Enter — Run the query (or selected text)
  • Ctrl + T — Open a new query tab
  • Ctrl + Shift + F — Auto-format SQL
  • Ctrl + W — Close the current tab
