Design Finite Automata Online

Automata Lab is a powerful, free online tool for designing and simulating deterministic finite automata (DFA) and nondeterministic finite automata (NFA). Perfect for computer science students studying theory of computation, formal languages, and automata theory.

Key Features

• Visual DFA Designer - Create deterministic finite automaton with drag-and-drop interface
• NFA Editor - Build nondeterministic finite automaton with epsilon transitions
• Real-time Testing - Test strings against your automata with step-by-step execution
• NFA to DFA Conversion - Convert NFA to DFA with automatic minimization
• Regex to NFA - Convert regular expressions to finite automata
• LaTeX Export - Export automata as TikZ code for academic papers
• JSON Import/Export - Save and share your automata designs

Educational Tool for Computer Science

Whether you're learning about finite state machines, studying for exams on automata theory, or teaching computational theory, Automata Lab provides an intuitive interface for exploring DFA and NFA concepts. Visualize state transitions, test input strings, and understand the relationship between regular expressions and finite automata.

Perfect for Academic Use

Export your finite state machines to LaTeX TikZ format for inclusion in research papers, homework assignments, and presentations. Support for both deterministic and nondeterministic automata makes this tool ideal for computer science education at all levels.
