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.
Produces standard UUID v4 format (xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx) following RFC 4122. Every UUID is unique across the planet.
Generate up to 100 UUIDs at once. Useful for seeding test data, generating a batch of resource IDs, or building import fixtures.
Copy a single UUID or the entire batch with one click. Paste directly into your code, database seeds, or documentation.
Uses crypto.randomUUID() under the hood — the browser's secure random number generator. Safe for security-sensitive use cases.
All UUIDs generate in under a millisecond — no server round-trip, no waiting. Click the button and the list is ready.
Export the whole batch as a .txt file with one UUID per line — easy to import into databases, scripts, or CSV tools.
Generate 50 UUIDs to populate a test database with realistic primary keys. No bespoke generation script needed.
Generate a single UUID to use as a correlation ID when debugging distributed systems — trace a single request across services.
Download a batch of UUIDs as a text file to import into your fixture loader for realistic test scenarios.
Generate UUIDs to use as API keys or tokens — simple, globally unique, and cryptographically strong.
When building a resource (file, asset, temp directory) that needs a unique name, generate a UUID instead of using timestamps.
Click the UUID icon in the DevSuite Pro dock. A panel opens showing a count input and a Generate button.
Enter how many UUIDs you need — 1 for a single ID, or up to 100 for bulk. Default is 10.
Press the Generate button. The full list appears instantly — each UUID on its own line with a per-row Copy button.
Click Copy on any single row for one UUID, or use Copy All to grab the entire batch at once.
For large batches, click Download .txt to save the whole list as a file — easy to import into scripts or databases.
