UUID Generator

UUID Generator produces cryptographically strong UUID v4 identifiers using the browser's crypto API. Generate a single UUID or a bulk list (up to 100 at a time). One-click copy individual UUIDs or the whole batch, and download the list as a text file.

Unique identifiers are everywhere in modern applications: database primary keys, correlation IDs, session tokens, request IDs, API keys, and resource identifiers. UUID v4 is the most common format because it's globally unique, doesn't require coordination, and can be generated client-side without a database round-trip. This tool generates UUIDs using crypto.randomUUID() — the browser's cryptographically strong random number generator — so the output is suitable for security-sensitive uses. Generate one at a time or in bulk (useful for seeding test data, populating migration fixtures, or generating a batch of resource IDs). One-click copy grabs a single UUID or the entire batch; download the full list as a .txt file for import into your tools.

Ключевые особенности

UUID v4 Generation

Produces standard UUID v4 format (xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx) following RFC 4122. Every UUID is unique across the planet.

Bulk Generation

Generate up to 100 UUIDs at once. Useful for seeding test data, generating a batch of resource IDs, or building import fixtures.

One-Click Copy

Copy a single UUID or the entire batch with one click. Paste directly into your code, database seeds, or documentation.

Cryptographically Strong

Uses crypto.randomUUID() under the hood — the browser's secure random number generator. Safe for security-sensitive use cases.

Instant Generation

All UUIDs generate in under a millisecond — no server round-trip, no waiting. Click the button and the list is ready.

Download as Text File

Export the whole batch as a .txt file with one UUID per line — easy to import into databases, scripts, or CSV tools.

Типичные сценарии использования

Seeding Test Data

Generate 50 UUIDs to populate a test database with realistic primary keys. No bespoke generation script needed.

Creating Correlation IDs

Generate a single UUID to use as a correlation ID when debugging distributed systems — trace a single request across services.

Populating Fixture Files

Download a batch of UUIDs as a text file to import into your fixture loader for realistic test scenarios.

API Key Generation

Generate UUIDs to use as API keys or tokens — simple, globally unique, and cryptographically strong.

Naming Unique Resources

When building a resource (file, asset, temp directory) that needs a unique name, generate a UUID instead of using timestamps.
