💡 This is your workspace. Files holds your project: add files, upload pictures, switch pages. A website shows a live Preview on the right; Python, JavaScript and C++ show a live Flowchart and run in the Terminal. Find (Ctrl+H) searches and replaces.
Commands: forward(), turnLeft(), turnRight(), wallAhead(), atGoal(). Loops and if work too.
Python code with pygame or turtle plays on the screen on the right. This is Fernbyte's own simple version: shapes, text, keys, mouse and touch work. Images, sprites and sounds don't yet.
Free is a complete way to learn and build. Pro removes the limits and unlocks everything. No account is needed: Pro works with a license key.
Pro keys aren't switched on for this copy yet. The site owner needs to add a public key to config.js (see the README).
