UUID Generator

Generate UUID v1, v3, v4, v5 instantly for testing, unique IDs, API tokens, and database seeding. No coding needed – just select version, hyphen format, and optionally provide name and namespace for v3/v5. Get results via Dataset, Key-value store OUTPUT, or API. Fast, scalable, free trial.

Why Use UUID Generator?

• Instant IDs: Single-click generation for dev workflows.
• Multiple versions: Random (v4), time-based (v1), deterministic (v3/v5).
• Deterministic support: Use name and namespace for repeatable v3/v5 UUID generation.
• Apify platform: Schedule runs, API access, monitoring, integrations.
• Export ready: JSON/CSV download, perfect for test data.

Features

• Generate v1 (time-based), v3 (MD5 hash), v4 (random), v5 (SHA-1 hash).
• Hyphen on/off formatting.
• Optional name, namespaceType, and namespace inputs for v3/v5.
• Free trial covers hundreds of runs.
• Run via API, schedule, or webhook.

Input Options

Click the input tab for full schema.

Field	Type	Description	Default
version	Select	UUID version: v1, v3, v4, v5	v4
hyphen	Boolean	Include hyphens (-)	true
name	String	Used for v3/v5. Same name + same namespace = same UUID	"default-name"
namespaceType	Select	Namespace type for v3/v5: DNS, URL, custom	DNS
namespace	String	Custom namespace UUID, used only when namespaceType = custom	"6ba7b810-9dad-11d1-80b4-00c04fd430c8"

Notes:

• name, namespaceType, and namespace are mainly used for v3 and v5.
• For v1 and v4, those fields are ignored.
• For v3/v5, the same name and namespace will always generate the same UUID.

Example input (v4):

{
  "version": "v4",
  "hyphen": false
}

Example input (v3 + custom namespace):

{
  "version": "v3",
  "hyphen": true,
  "name": "my-user-id",
  "namespaceType": "custom",
  "namespace": "6ba7b810-9dad-11d1-80b4-00c04fd430c8"
}

Example input (v5 + DNS namespace):

{
  "version": "v5",
  "hyphen": false,
  "name": "example.com",
  "namespaceType": "DNS"
}

Output Data

Results saved to default Dataset (export JSON/CSV) and Key-value store OUTPUT.

Output Table

Field	Type	Description	Example
uuid	String	Generated UUID	"550e8400e29b41d4a716446655440000"
version	String	Used version	"v4"
hyphen	Boolean	Hyphen setting	true
createdAt	String	ISO timestamp	"2026-03-17T05:37:00Z"
name	String	Provided name for v3/v5 only	"example.com"
namespaceType	String	Namespace type for v3/v5 only	"DNS"
namespace	String	Namespace value for v3/v5 only	"DNS"

Example output (v4):

{
  "uuid": "550e8400-e29b-41d4-a716-446655440000",
  "version": "v4",
  "hyphen": true,
  "createdAt": "2026-03-17T05:37:00.000Z"
}

Example output (v5 + DNS namespace):

{
  "uuid": "cfbff0d1-9375-5685-968c-48ce8b15ae17",
  "version": "v5",
  "hyphen": true,
  "createdAt": "2026-03-17T05:37:00.000Z",
  "name": "example.com",
  "namespaceType": "DNS",
  "namespace": "DNS"
}

How to Use UUID Generator

1. Run Actor (default generates v4 with hyphens).
2. Customize via input: select version, toggle hyphen.
3. For v3 or v5, optionally provide name, namespaceType, and namespace.
4. If using custom namespace, provide a valid namespace UUID.
5. Download Dataset (JSON/CSV) or fetch OUTPUT via API.
6. Schedule/API for automation.

💡 Quick test: Run now – get UUID in seconds!

Pricing

• Free trial: ~$5 credits = thousands of UUIDs.
• Pay-per-run: Low CU usage (minimal compute).
• Scales to millions of IDs without extra cost.

Tips

• v4: Default for random unique IDs.
• v1: Useful when you want time-based UUIDs.
• v3/v5: Deterministic – same input = same UUID.
• No hyphen: Compact 32-char format for URLs.
• API: curl or SDK for batch generation.

FAQ

Is UUID Generator free?

Free trial covers extensive testing. Production: pay-per-compute (very low).

v3 vs v5?

v3 (MD5): Legacy. v5 (SHA-1): Modern deterministic.

Why do v3 and v5 need name and namespace?

Because v3 and v5 are name-based UUIDs. The same name and namespace combination always produces the same UUID.

Legal to use?

UUIDs are standard – generate unlimited test data ethically.
