Mockaroo is a realistic mock data generator and API mocking service used by developers and QA teams to produce JSON, CSV, TXT, custom-delimited, SQL, and XML test data. The platform combines a schema designer, 150+ built-in field types (Name, Internet, Address, Business, Date, Currency, Geographic, Phone, Health, Technology, and more), named datasets used as lookup sources, hosted mock APIs, formulas, projects, AI-assisted field generation, de-identification, and a REST API for programmatic generation. Mockaroo ships in four tiers (Free, Silver, Gold, Enterprise), with the Enterprise tier available as a Docker image for self-hosted, unlimited generation.
Mockaroo publishes 4 API contracts indexed on the APIs.io network, including Datasets API, Downloads API, Generate API, and 1 more. Tagged areas include Test Data, Mock Data, API Mocking, Data Generation, and Developer Tools.
The Mockaroo catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Mockaroo’s developer surface includes authentication, documentation, signup flow, pricing, engineering blog, support, and 28 more developer resources.

Full breakdown ↓
scored 2026-11-06 · rubric v0.27.0 · Show this score on your site →
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Open Source Surface applies to this provider. This product is open source and we
read its repository directly, so Open Source Surface carries
10 points of the composite. It is scored from what the repository actually
publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the
provider rather than inferred from our own catalog pointers.
This facet adds; nothing was taken away to make room for it. An open-source project is not excused from
the commercial facets, because exemption would strip it of the points it does earn.
If we have the wrong repository, or this product is not open source, say so on your
provider repo and we
will drop the facet rather than have you publish against it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 65 points between them,
because both conditional facets apply and carry
35 points together. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 65% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
MCP Server+12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Idempotency+9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics+8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card+8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Delegated User Identity+6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
8 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
Generate realistic test records using more than 150 built-in field types spanning names, addresses, business, internet, dates, currency, geography, phone, health, and technology...
Multiple Output Formats
Export generated data as JSON, CSV, tab-separated TXT, custom delimiter, SQL INSERT statements, or XML.
Schema Designer
Design, save, and reuse schemas in the web UI, then call them by name from the REST API.
Datasets As Lookup Sources
Upload CSV or plain-text datasets and use them as lookup sources in schemas via the Dataset Column field type.
Mock APIs
Host mock REST endpoints that return generated records on demand, including configurable error conditions.
Background Generation
Submit large generation requests asynchronously and poll /api/downloads/{id} for status, progress, and the final download URL.
Formulas And Custom Functions
Transform generated values with reusable Mockaroo formula expressions and custom functions.
AI Field Generation
Generate field definitions and custom types using AI assistance in the schema editor.
De-identification
Anonymize sensitive datasets via Mockaroo's de-identification tooling.
Enterprise Docker Deployment
Run Mockaroo as a self-hosted Docker container inside a private cloud or datacenter for unlimited, organization-wide generation.
