A PokeAPI alternative for practising writes and errors
PokeAPI is a free, open, community-maintained RESTful API with comprehensive Pokémon data — species, moves, abilities, types, items, evolution chains and much more — reached with GET requests. It is the reference choice for any app that needs accurate Pokémon information, and a popular first API for learning to fetch and render JSON.

Best for
Building an app with real Pokémon data
Practising API testing with a familiar theme
Where it stops
It is read-only by design: there is nothing to create, update or delete, and so no conflicts, validation failures or authentication to practise. It also asks for fair use and recommends caching, which means it is the wrong target for load tests or for hammering in a loop while learning.
What is different here
The Pokémon API here is unofficial, fan-made and much smaller, with invented data — and it accepts writes. You can catch (POST), level up (PUT with If-Match), release (DELETE with a viewer token that gets a 403) and simulate battles, against a sandbox that is yours alone, with a full set of failure codes and interactive docs around it.
What PokeAPI does better
Accurate, comprehensive Pokémon data — the real thing, for real apps.
A large, well-known dataset with evolution chains, moves and sprites.
Widely used in tutorials and with community client libraries in many languages.
What this playground does better
Create, update and delete endpoints, with state that persists in your sandbox.
Authentication and roles, optimistic concurrency and validation errors to test.
No shared fair-use concern: your sandbox is isolated, and the engine runs in your browser.
Sits in a catalog of 39 APIs with guides and challenges built on them.
Which to use
For anything that needs true Pokémon data, use PokeAPI. For practising writes, auth and error handling with the same theme, use this — it is unofficial and its data is invented on purpose.

Other comparisons
JSONPlaceholder — JSONPlaceholder fakes its writes. If you need a POST that a later GET can find, that is the difference.
httpbin — httpbin shows you the request. This shows you an API. They answer different questions.
reqres.in — reqres is a clean, tiny user API with fake auth. The gap is everything past the happy path.
json-server — json-server turns a JSON file into a REST API in seconds. It does not push back — and that is the difference.
WireMock — WireMock reproduces the API you already know, exactly. This one gives you an API you do not control.
Mockoon — Mockoon is for designing your own mock API. This one is an API already designed, with rules you have to discover.
Beeceptor — Beeceptor gives you a hosted endpoint to inspect and mock. This gives you finished APIs that behave like real ones.
DummyJSON — DummyJSON has rich sample data and a JWT login. Its writes are simulated; here they persist.
Postman mock servers — A Postman mock server replays the examples saved in a collection. This one runs an API with state and rules.
SWAPI — SWAPI serves Star Wars data, read-only. This Star Wars API is invented practice data you can change.
