Modern software development requires constant micro-transformations: inspecting JWT payloads, formatting minified JSON logs from CloudWatch, checking regex patterns, and comparing code diffs.
Installing bulky native apps or firing up heavyweight IDE plugins for a 5-second task interrupts flow state. Having a suite of instant, zero-latency browser utilities eliminates friction while keeping sensitive code local.
1. Client-Side JSON Formatter & Validator
Never paste proprietary database dumps or production API responses into third-party cloud scratchpads. Elixuvo's [JSON Formatter](/tools/text/json-formatter) validates syntax, highlights keys, and formats payloads entirely in your browser with zero data retention.
2. Base64 Encoder & Decoder
Quickly convert strings, authentication headers, and asset snippets between plain text and Base64 representations using [Base64 Converter](/tools/developer/base64-converter) without exposing tokens to external endpoints.
3. Interactive Regex Tester & Visualizer
Debugging regular expressions is much faster with real-time feedback. [Regex Tester](/tools/developer/regex-tester) highlights matches as you type, supports all standard ECMAScript flags, and details captured groups instantly.
4. Cryptographic Hash & Checksum Generator
Compute SHA-256, SHA-512, and MD5 hashes in your browser using the native Web Crypto API via [Checksum Generator](/tools/developer/checksum-generator) to verify package integrity or generate database keys.
5. Code & Text Diff Checker
Compare configuration files, pull request snippets, or API schemas side-by-side using [Code Diff](/tools/developer/code-diff) with line-by-line visual diff markers.
6. SQL Query Formatter & Beautifier
Transform messy, minified raw SQL queries from application logs into cleanly indented, keyword-capitalized statements using [SQL Formatter](/tools/developer/sql-formatter).
7. UUID v4 & v5 Generator
Generate single or batch RFC 4122 compliant UUIDs for database seeding and testing with true browser cryptographic entropy via [UUID Generator](/tools/developer/uuid-generator).
8. CSS Box Shadow Generator
Design multi-layered, smooth box shadows visually and copy clean cross-browser CSS code using [Box Shadow Generator](/tools/developer/box-shadow-generator).
9. URL Parser & Query String Inspector
Break down complex URLs into protocol, hostname, path, and decoded key-value query parameters with [URL Parser](/tools/developer/url-parser).
10. HTML Entity Encoder & Decoder
Safely escape and unescape reserved HTML characters (`<`, `>`, `&`, `"`) to prevent XSS vulnerabilities when displaying user input via [HTML Entity Codec](/tools/developer/html-entity-codec).
