JSONPlaceholder

JSONPlaceholder is a free, no-auth fake REST API for prototyping, tutorials, and testing. It exposes six relational resources — posts, comments, albums, photos, todos, and users — over six standard REST routes per resource. All write operations (POST, PUT, PATCH, DELETE) are accepted and respond as if successful, but no changes are persisted. The service is built on the open-source json-server engine (also by typicode) and serves billions of requests per month with no rate limits or authentication.

JSONPlaceholder publishes 6 APIs on the APIs.io network, including Albums API, Comments API, Photos API, and 3 more. Tagged areas include Development, Testing, Prototyping, Fake API, and Open-Source.

The JSONPlaceholder catalog on APIs.io includes 2 JSON-LD contexts and 2 Spectral governance rulesets.

JSONPlaceholder’s developer surface includes getting-started guide, engineering blog, documentation, pricing, and 18 more developer resources.

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.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/jsonplaceholder: open an issue to ask a question, or submit a pull request to add artifacts.

Features 8

Notable capabilities this provider offers.

Six Relational Resources

Posts, comments, albums, photos, todos, and users with realistic relationships between them (posts belong to users, comments belong to posts, etc.).

Full REST Surface

GET, POST, PUT, PATCH, and DELETE methods are accepted on every resource — write operations simulate success without persisting changes.

Nested Routes

Single-level nested access such as /posts/1/comments, /albums/1/photos, and /users/1/todos for relational queries.

Query Filtering

Basic query-string filtering on any resource field (e.g. /comments?postId=1, /posts?userId=1).

No Authentication

Open to the public — no API keys, OAuth, or signup required. Use it in tutorials, sandboxes, and frontend demos freely.

No Rate Limits

The service does not publish or enforce documented rate limits and routinely serves about three billion requests per month.

CORS Enabled

All origins are allowed, making the service usable directly from browser-based applications without a proxy.

HTTPS Only

Served exclusively over HTTPS for safe inclusion in modern web tutorials and demos.

Use Cases 6

What developers build with this provider.

Frontend Prototyping

Wire up React, Vue, Angular, or Svelte tutorials against a real HTTP endpoint without standing up a backend.

API Client Testing

Exercise HTTP client libraries (fetch, axios, requests, OkHttp) against a stable public REST surface.

Tutorial and Courseware

Power coding tutorials, bootcamp exercises, and conference workshops that need a deterministic JSON API.

Mobile App Demos

Drive iOS and Android sample apps that demonstrate networking, list rendering, and CRUD flows.

Tooling QA

Smoke-test API generators, codegen tools, SDK builders, and OpenAPI tooling against a stable real-world API.

Workshop Sandboxes

Provide a no-signup HTTP API for hands-on workshops where participants cannot wait for credentials.

Integrations 5

Pre-built integrations with other platforms and tools.

json-server

The open-source engine that powers JSONPlaceholder — runs the same fake REST API locally with a single command.

lowdb

The tiny local JSON database that json-server uses for storage; ships from the same typicode org.

Postman

Public collections wrap JSONPlaceholder for quick HTTP exploration and learning.

Hoppscotch

Frequently used as the default example endpoint in HTTP clients including Hoppscotch and Insomnia.

MSW (Mock Service Worker)

Often paired with MSW so frontend tests can intercept and stub JSONPlaceholder traffic deterministically.

Solutions 2

Packaged solutions this provider offers.

Local Mirror via json-server

For teams that need write persistence or offline development, install json-server, point it at a local db.json, and reproduce JSONPlaceholder routes verbatim.

My JSON Server

typicode operates an additional service (My JSON Server) that turns any GitHub-hosted db.json into a personal hosted fake REST API.
