Getting the right combination of values to achieve subtle card shadows, dramatic drop shadows, or layered effects can require a lot of experimentation. This visual generator makes it easy to dial in exactly the shadow you want and get the CSS in seconds.

Common uses: creating card and panel shadows for UI components, building material design elevation effects, generating neumorphic shadow combinations, adding depth to buttons and inputs, and designing layered shadow systems for design tokens.

About the Flexbox Playground

Experiment with CSS Flexbox properties visually with a live preview. Adjust flex-direction, justify-content, align-items, flex-wrap, and gap, add or remove flex items, and see the layout update in real time. Copy the generated CSS output directly into your stylesheet.

Flexbox is the most widely used CSS layout mechanism, but getting the alignment and spacing exactly right can require trial and error. This interactive playground lets you explore how different property combinations affect layout without writing or reloading any code, making it an excellent learning tool and a quick practical reference.

Common uses: learning how flexbox properties interact, building navigation bars and toolbars, centering content both horizontally and vertically, creating card grids with proper alignment, and prototyping responsive layouts quickly.

About the Border Radius Generator

Generate CSS border-radius values visually with independent sliders for each corner. Control top-left, top-right, bottom-left, and bottom-right radius values separately to create everything from simple rounded corners to asymmetric shapes. See the live preview update and copy the CSS output instantly.

CSS border-radius allows you to create rounded corners, pill shapes, circles, and complex asymmetric curves. While simple equal-corner rounding is straightforward, this generator makes it easy to experiment with independent corner values and create the exact shape you need for buttons, cards, avatars, and other UI elements.

Common uses: creating rounded card components, generating pill-shaped buttons, building avatar circle styles, designing custom-shaped UI elements, and creating asymmetric organic shapes for decorative elements.

About the Text to Binary Converter

Convert any text string to its binary (base-2) representation and decode binary back to text instantly. Each character is converted to its 8-bit ASCII binary code separated by spaces. Live conversion updates both fields as you type in either direction. All processing is done locally in your browser.

Text to binary conversion is commonly used in computer science education, puzzle-making, and encoding exercises. Each ASCII character maps to an 8-bit binary pattern, making this a useful tool for understanding how text is represented at the bit level or for creating encoded messages.

Common uses: learning how ASCII text maps to binary, creating binary-encoded puzzles and ciphers, understanding character encoding for computer science courses, converting small messages for educational demonstrations, and decoding binary strings encountered in programming exercises.

About the JSONPath Tester

Query and extract specific values from JSON using dot-notation path expressions. Paste your JSON object and enter a path like store.books.0.title to navigate nested structures and extract exactly the data you need. Results are displayed instantly as you type the path.

JSONPath expressions let you navigate complex nested JSON structures without writing custom parsing code. This is particularly useful when debugging API responses, working with deeply nested configuration files, or learning how to extract specific fields from large JSON datasets. The dot-notation syntax is intuitive and easy to learn.

Common uses: extracting specific fields from API responses, navigating nested JSON configuration objects, debugging complex data structures, learning JSONPath syntax, and testing path expressions before implementing them in code.

About the Open Graph Preview

Preview how your webpage will appear as a social media card on Facebook, Twitter/X, LinkedIn, and other platforms that support Open Graph protocol. Enter a title, description, optional image URL, and site name to see an accurate mock preview of how the card will render when your URL is shared.

Open Graph tags control the appearance of your content when shared on social media — the difference between a plain URL and a rich card with image, title, and description. This preview tool lets you verify your OG configuration before deploying, so you can fix issues before they affect how your content looks to thousands of social media users.

Common uses: previewing OG tags before deploying a new page, verifying social sharing appearance after updating meta tags, designing compelling OG card layouts, checking how URLs appear when shared in messaging apps, and testing different title and description combinations for social media optimization.

About the WHOIS Lookup

Look up domain registration and ownership information including registrar, registration date, expiry date, nameservers, and registrant contact details. This free online WHOIS tool queries public domain registration records via an API so you get results without needing command-line access.

WHOIS data is useful for finding out who owns a domain, when it expires (for potential acquisition), which registrar manages it, and what nameservers it uses. It is commonly used by domain investors, security researchers, developers checking domain availability, and anyone investigating suspicious domains.

Common uses: checking domain registration and expiry dates, finding registrar information for domain transfers, investigating who owns a specific domain, verifying nameserver configuration, and checking when a domain was first registered.

About the JSON Diff

Compare two JSON objects side by side and see exactly what has changed. This tool highlights added keys in green, removed keys in red, and modified values in yellow, making it easy to spot differences at a glance. All comparison happens in your browser with no data sent to any server.

JSON diff is invaluable when reviewing API response changes, comparing configuration file versions, debugging data transformation pipelines, or reviewing test fixture changes. Instead of visually scanning two JSON blobs line by line, this tool gives you an immediate, color-coded summary of every change between the two objects.

Common uses: comparing API responses before and after a code change, reviewing changes to JSON configuration files, debugging data transformation outputs, spotting differences in test fixtures, and auditing changes to JSON-based settings files.

About the CURL to Code Converter

Convert curl commands to equivalent code in JavaScript (Fetch API), Axios, and Python requests instantly. Paste any curl command including headers, request body, authentication flags, and method specifications, and get clean, ready-to-use code in your preferred language. All conversion is done locally in your browser.

Developers frequently copy curl commands from API documentation, browser DevTools, or README files and need to translate them into code for their application. This converter handles the translation automatically, saving the time of manually mapping curl flags to the correct library methods and parameters.

Common uses: converting curl examples from API documentation to JavaScript fetch calls, translating DevTools-copied curl commands to Python requests, migrating shell scripts to programmatic HTTP clients, learning how curl options map to HTTP library parameters, and quickly testing API integrations.
