What Compillo is

Compillo is a free browser platform combining an online compiler, code editor, and learning environment. It lets users write, run, and test code without installing a local compiler or configuring a development environment. Listed languages include Python, C, C++, Java, JavaScript, HTML, and CSS. Sandbox provides language switching, live HTML and CSS output, custom themes, and file-state management. The Python playground is described as Python 3.11 running in WebAssembly, with NumPy, Pandas, and Matplotlib support. Compillo Labs offers five learning tracks and more than 180 interactive modules covering Python, C and systems fundamentals, Java, relational SQL, and data structures and algorithms. An RTU Lab Suite is configured for RTU syllabus practicals. Listed database engines include Pyodide and SQL.js, while the Python course covers SQLite and introduces MySQL, PostgreSQL, and ORM basics. Lesson progress is saved in the browser.
