Next-Gen Developer Utilities.
Zero Server Uploads. Instant WebAssembly.
The developer toolkit built for production engineers. Format JSON, decode JWTs, test regex, compare diffs, and generate cron expressions with 100% in-browser security.
All Developer Utilities
Showing 19 client-side developer tools
JSON Formatter & Validator
Format, validate, repair, and minify JSON with tree visualization, syntax highlighting, and 1-click JSON repair.
SQL Query Formatter
Beautify complex PostgreSQL, MySQL, SQLite, and BigQuery statements with standardized indentation and clause alignment.
JavaScript Beautifier & Minifier
Beautify messy JS bundles or compress code for production with variable preservation and syntax verification.
HTML & XML Formatter
Clean up nested HTML5 and XML markup, strip trailing spaces, and format standard tag indentations.
CSS Formatter & Minifier
Organize CSS rules, alphabetize declarations, and minify stylesheet bundles for maximum web performance.
JWT (JSON Web Token) Inspector
Decode header, payload, and signature claims of JWTs locally. Verify expiration dates without leaking sensitive credentials.
Base64 Encoder & Decoder
Encode UTF-8 strings and binary files into Base64 format or decode data URI payloads with zero server latency.
URL Encoder & Decoder
Encode query parameter strings into percent-encoding or safely decode nested URI components.
Cryptographic Hash Generator (SHA-256 / MD5)
Compute cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512) directly inside browser memory via Web Crypto API.
Secure UUID / GUID Generator
Generate RFC 4122 compliant UUID v4 tokens in bulk using browser-native cryptographically secure random values.
HTML Entity Escape & Unescape
Escape special characters (&, <, >, ", ') for safe embedding in HTML templates and prevent XSS injection bugs.
Code Diff & Side-by-Side Checker
Compare two code snippets or configuration files line-by-line with inline difference highlights and character diffs.
Regex Tester & Pattern Explainer
Test regular expressions against sample text with live match group inspection, substitution, and syntax breakdowns.
Cron Expression Schedule Builder
Build and validate cron job schedules visually with human-readable English descriptions and upcoming trigger dates.
Unix / Epoch Timestamp Converter
Convert between Unix timestamps in seconds/milliseconds and human-readable UTC/local ISO 8601 date strings.
Mock Data & JSON Schema Generator
Generate realistic mock datasets (users, addresses, UUIDs, dates) in JSON, CSV, and SQL format for testing APIs.
Punycode / IDN Domain Converter
Convert internationalized Unicode domain names (IDN) to ASCII punycode (xn--) and vice-versa.
IPv4 Integer, Hex & Radix Matrix
Convert IPv4 dotted-quad addresses to 32-bit Integer, Hexadecimal, Binary, and reverse in-addr.arpa format.
Markdown to HTML Live Previewer
Render GitHub Flavored Markdown (GFM) with live preview, syntax highlighting, and clean HTML export.
Your API Keys & Production Payloads Never Touch Remote Servers
Legacy cloud converters send your confidential JSON payloads, API tokens, and JWT claims to third-party PHP backend servers. Ubify executes all parsers, linters, and cryptographic hashes in an isolated local browser sandbox.
Developer Studio Frequently Asked Questions
Is it safe to paste confidential production JWTs or JSON?
Yes, 100%. All formatting, JWT decoding, and regex evaluation happen locally on your client machine using JavaScript and WebAssembly. No data is ever transmitted over network sockets or stored in server databases.
How fast does the Code Diff tool handle massive files?
Because diff calculation runs in your local CPU thread, it computes differences between thousands of lines of code in milliseconds without network upload throttling or queue delays.
