JSONPlaceholder is a free, online, fake REST API designed for frontend development, testing, prototyping, and learning RESTful concepts without needing a backend server. It provides realistic mock JSON data for common resources like users, posts, todos, comments, albums, and photos, with simulated CRUD operations (GET, POST, PUT, PATCH, DELETE). All write operations are non-persistent—changes are not saved, making it ideal for safe experimentation.
Key Features:
No registration or setup required.
Cross-origin (CORS) support and compatible with React, Angular, Vue, and other frameworks.
Pagination via query parameters like
?_page=1&_limit=10.Relationships between resources (e.g., posts have many comments).
Powered by JSON Server + LowDB, serving billions of requests monthly.
Common Use Cases:
Testing API calls in tutorials, demos, or GitHub READMEs.
Building UIs with placeholder data.
Learning how REST APIs work without backend implementation.
Limitations:
Not for production use—data is fixed and not persisted.
No authentication, user sessions, or data persistence.
Not suitable for CI/CD or QA automation requiring real data state.
Alternatives for Advanced Needs:
DummyJSON: More data types, sorting, and filtering.
ReqRes: Supports authentication, persistent data, and request logging.
Beeceptor: Custom mock servers with dynamic responses.
Fake Store API: E-commerce-specific data.

Placeholders in JSON - is there a better method?
What you're doing is a mix of Json but also rudimentary templating. There's libraries out there that can do the heavy lifting for you but your approach is basically the type of thing being done by those implementations - replace "$something" with "something else". More advanced/mature ones can do conditionals, loops and other sorts of things a little fancier than a basic string replacement. So, the way you're going now is fine and reasonable but if you find you need more control, smarter replacements or a giant mess of spaghetti code rolling your own solution you could look up some Python templating libraries to use for the heavy lifting instead. One thing to be careful of however is the format for your "variables" getting replaced, they should not overlap with values you might expect to show up in your data already so they they can be uniquely targeted without catching any unintended cases accidentally. Commonly the dollar sign is a popular candidate used across multiple languages/data. Also can be combined/wrapped with braces for even less chance of unintended matching. eg "Replace {$my-variable} in this sentence". More on reddit.com

JSONPlaceholder API – Free Fake REST API for Testing & Prototyping ...
What can I use instead of JSONPlaceholder?
Alternatives to JSONPlaceholder include ReqRes (adds auth, persistent data, and logs), DummyJSON (more data types), Beeceptor (custom mock servers), and Fake Store API (e-commerce data). ReqRes is the best option if you need authentication flows or data that persists between requests.

Is JSONPlaceholder good for production testing?
JSONPlaceholder is excellent for learning and quick prototyping, but it lacks features needed for production-grade testing: no auth, no persistent storage, no logs, and no per-user data isolation. For CI/CD and QA automation, a more complete API like ReqRes is better suited.

r/learnprogramming on Reddit: Placeholders in JSON - is there a better method?
March 21, 2020 -
I'm working on a Python script to generate all of the directories and base files I typically create when making a new project. I have a JSON file which stores the directories, the files in each, and the contents of those files.
Right now I have a placeholder value of "<app_name>" in the JSON object that needs to be replaced with the app name provider via user input, but I feel like this is not the right approach for JSON. Is there a standard way to have a placeholder value in JSON objects, or is there a more appropriate way of storing this information?
