dfa-draw

A simple JS web application where you can create and run DFAs (deterministic finite automata).

How to

Start by adding an alphabet (such as {1, 0}).
Next, click on the canvas and add your states and transitions.
The ‘console’ on the right will notify you of errors in your automata.
Create a state on the mouse position by pressing ‘Q’.
Select a state by left-clicking on it.
Move a state by left-clicking on a state and moving the cursor.
Create transitions by pressing ‘E’ once a state is selected, and then left-clicking another state.
Remove transitions or states by pressing ‘DEL’ once a state or transition is selected.
Rename the selected state by pressing ‘R’.
Set a state as Final by pressing ‘F’.
Set a state as Start by pressing ‘S’.
