Text Processing

Slug Generator

Generate clean URL slugs from any text, with built-in Chinese-to-Pinyin conversion. Collapse separators, lowercase, and optional max-length word-aware truncation.

Development

SQL Query Formatter & Minifier

Beautify or minify SQL with full control over dialect (PostgreSQL, MySQL, SQLite, SQL Server/T-SQL, BigQuery, Snowflake, and more), keyword / identifier / function casing, indent style (standard, tabular-left, tabular-right), and spacing between statements. Produces a syntax-highlighted, copy-ready result with live size and statement stats.

Text Processing

Glitch Text

Create a glitchy / corrupted look by replacing each letter with neighbouring broken Unicode glyphs — Cyrillic/Greek look-alikes, block elements (█▓▒░), geometric shapes — for a flat smashed data-corruption aesthetic. Intensity slider + optional seed for reproducible results.

Text Processing

Text Repeater

Repeat text N times with a chosen separator — inline, new line, or a numbered countdown. The quick tool for chat spam, dramatic build-ups, and social-media effect.

Cryptography

Hash Algorithm Comparator

Hash the same input with MD5, SHA-1, SHA-256, SHA-512, BLAKE2b, and BLAKE3 at the same time and compare them side by side: output length, hex/Base64 digest, security status (broken / modern), and a relative speed benchmark. Great for teaching, choosing a hashing algorithm, or sanity-checking checksums.

Text Processing

Small Caps Converter

Convert text to Unicode small capitals (ʜᴇʟʟᴏ). Uses Phonetic Extensions small-cap glyphs; letters without a dedicated glyph fall back to lowercase.

Text Processing

Zalgo Text Generator

Apply the "zalgo" corruption effect — stack random combining marks onto each character for a haunted/glitchy look. Adjustable intensity + optional seed.

Security

Secure Random Generator

Generate cryptographically secure random key material driven by entropy budget — request N bits of entropy, get hex/base64/base64url output. Also supports custom-alphabet strings via crypto.randomInt (rejection-sampled, no modulo bias). Use this instead of Math.random()-based tools for any secret/key/token.

Security

Security Headers Checker

Audit HTTP response headers for security compliance — parses the raw headers you paste (no network) and grades them against the OWASP secure-header set with value-level checks: HSTS max-age, CSP unsafe-inline/eval, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP/COEP/CORP and more. Outputs a letter grade (A+ to F) plus per-header findings with copy-ready fix recommendations.

Security

Shamir Secret Sharing

Split a secret into n shares where any k (the threshold) are required to reconstruct it — Shamir's k-of-n scheme over GF(256). Pure in-process cryptography (crypto.randomBytes for polynomial coefficients), no network. Split a password/key/passphrase into shares held by separate people, then combine any k of them to recover it. Confidentiality only — no authenticity.

Development

JSONPath REPL Playground

An interactive JSONPath REPL that runs multi-step query pipelines against any JSON. Write one JSONPath expression per line (e.g. $..book[?(@.price<10)] then $[0:5]) and see each step's matches with counts, paths, and values — plus a shareable URL that encodes your data and pipeline. Supports recursive descent ($..), wildcards ([*]), filters ([?(@.price<10)]), slices ([0:5:2]), and negative indices.

Security

SSH Key Pair Generator

Generate an SSH key pair (Ed25519 recommended, RSA 4096, or ECDSA P-256) with an OpenSSH-format public key ready for ~/.ssh/authorized_keys, a SHA256 fingerprint, and a PEM private key. Optional passphrase encryption. Runs locally.
