Suite: Unique IDs & Web3 · 12 Live Utilities

Unique IDs & Web3

Generate RFC 9562 UUID v7, v4, ULID, NanoID, BIP-39 mnemonic seeds and validate crypto wallet addresses. All tools run strictly inside your browser thread via the W3C Web Cryptography API with zero remote telemetry.

RFC 4122 v4 Standard

UUID v4 (Random) Generator

Generate cryptographically random UUID v4 (Universally Unique Identifiers) in your browser using window.crypto.getRandomValues. Bulk generation available.

RFC 4122 v1

UUID v1 (Timestamp-Based) Generator

Generate timestamp and MAC/node-based UUID v1 identifiers client-side. Inspect timestamp and sequence components.

RFC 4122 v5

UUID v5 (Namespace SHA-1) Generator

Generate deterministic name-based UUID v5 identifiers using SHA-1 hashing of a namespace (DNS, URL, OID) and name string in your browser.

ULID Spec Sortable 128-bit

ULID (Universally Unique Lexicographically Sortable ID) Generator

Generate 26-character Crockford Base32 ULID identifiers. 128-bit compatibility with UUIDs, 1-millisecond timestamp precision, and URL-safe characters.

ULID Parser

ULID Timestamp & Randomness Decoder

Decode 26-character ULID strings into their exact Unix millisecond timestamp, human-readable ISO date, and 80-bit randomness payload in your browser.

NanoID CSPRNG Compact & Safe

NanoID Secure Collision-Resistant ID Generator

Generate compact, URL-friendly unique IDs using the NanoID algorithm. Smaller than UUID (21 characters) with equal or higher collision resistance.

identifiers Launch Tool →
CUID2 Next-Gen ID

CUID2 Secure Next-Gen Unique ID Generator

Generate collision-resistant, horizontal-scale CUID2 identifiers designed for modern web applications and distributed databases.

identifiers Launch Tool →
Segment KSUID

KSUID (K-Sortable Unique ID) Generator

Generate Segment K-Sortable Unique Identifiers (KSUID). 27-character base62 strings sorted naturally by second-level timestamp.

identifiers Launch Tool →
64-bit Snowflake Discord / Twitter

Discord/Twitter Snowflake ID Timestamp Extractor

Extract exact creation timestamps, worker IDs, and sequence numbers from 64-bit Snowflake IDs used by Discord, Twitter (X), and Mastodon in your browser.

identifiers Launch Tool →
BIP-39 CSPRNG Web3 Wallet

BIP-39 Mnemonic Seed Phrase Generator (12/24 Words)

Generate 12-word (128-bit) and 24-word (256-bit) BIP-39 mnemonic seed phrases using browser CSPRNG. Safe offline simulation with zero secrets logged.

identifiers Launch Tool →
Base58 / EIP-55 Multi-Chain

Crypto Address Validator (BTC, ETH, SOL)

Validate public blockchain addresses for Bitcoin (Legacy, SegWit, Taproot), Ethereum (EIP-55 checksum validation), and Solana in your browser.
