Tool StudioDecode, verify, and generate JWT & PASETO tokens
Paste a token
Drop in a JWT or PASETO token to decode.
Inspect the parts
View header/payload/signature broken out and highlighted.
Generate if needed
Build a new token with a custom payload and algorithm.
Paste a JWT or PASETO token to instantly see its decoded header, payload, and signature — or generate a new token with a custom payload and algorithm. Built for debugging auth flows.
Yes — provide the secret or key and it'll verify the signature is valid.
No, all decoding, verification, and generation happens entirely in your browser.
Interactive sorting algorithm visualizer to watch and learn how different sorting algorithms work in real-time. Visualize Bubble Sort, Selection Sort, Insertion Sort, Merge Sort, Quick Sort, and Heap Sort with step-by-step animations. Perfect for computer science students, developers preparing for interviews, and anyone learning data structures and algorithms. Features 6 different sorting algorithms with live visualizations, adjustable speed control from very slow to very fast, variable array size from 10 to 150 elements, real-time statistics showing comparisons and swaps, color-coded visualization with different colors for comparing (yellow), swapping (red), pivot (orange), and sorted (green) elements, live timer tracking execution time, responsive design that works on desktop, tablet, and mobile, dark and light theme support, and educational complexity information for each algorithm showing best, average, worst, and space complexity. Watch every comparison and swap as it happens with smooth animations. Generate new random arrays instantly. Stop and restart sorting at any time. Learn algorithm efficiency by comparing different sorting methods on the same data. Understand time complexity differences between O(n²) and O(n log n) algorithms visually. See how divide-and-conquer algorithms like Merge Sort and Quick Sort partition and solve sub-problems. Observe the heap building process in Heap Sort. All processing happens entirely in your browser with no data sent to servers. Perfect for visual learners, interview preparation, classroom teaching, algorithm comparison, and self-paced education.
Compare two texts side-by-side with color-coded highlighting for additions, deletions, and modifications. Supports line-by-line, word-level, and character-level comparison modes. Perfect for code review, document comparison, and tracking changes.
Search up to 5 words simultaneously with color-coded highlighting, occurrence counters, and easy navigation. Perfect for analyzing documents, finding patterns in large texts, and reviewing content with multiple search terms at once.
Format, validate, and beautify JSON data instantly. Minify JSON, fix formatting errors, and validate JSON syntax online. Perfect for developers working with APIs and configuration files.
