JSONPlaceholder

Overview JSONPlaceholder provides a free, fake online REST API for developers who need placeholder data during testing and prototyping. It serves roughly 3 billion requests each month, powered by JSON Server and LowDB. The service helps frontend developers, tutorial authors, and open-source contributors avoid scaffolding dummy data from scratch. It offers six common resource types — posts, comments, albums, photos, todos, and users — with relationships between them. Key Benefits Supports all HTTP methods including GET, POST, PUT, PATCH, and DELETE for full CRUD operations. Includes six pre-built resources with realistic relational data: 100 posts, 500 comments, 100 albums, 5000 photos, 200 todos, and 10 users. Accepts both http and https protocols for maximum compatibility with local and production environments. Enables developers to create their own fake REST server via the Mockend sponsor tool and a simple GitHub repo. Handles approximately 3 billion requests per month, indicating reliable uptime and traffic capacity. How It Works You send standard HTTP requests to endpoints such as /posts , /posts/1/comments , or /comments?postId=1 from a browser console, a code sandbox, or any HTTP client. The API returns JSON-formatted fake data that mimics a real backend, and you can use any method — GET to read, POST to create, PUT to update, PATCH to partially update, or DELETE to remove resources. Use Cases Frontend developers testing component rendering with realistic data shapes before a real backend is ready. Tutorial and blog post authors who need sample API responses in code examples on platforms like Stack Overflow or GitHub README files. Open-source contributors setting up demo applications on CodeSandbox or similar sandbox environments. Local developers prototyping new features without running a local database server or seeding data manually. Educators teaching REST API concepts who want a live, accessible endpoint students can hit from any device. Why Choose This Product Any developer who needs quick, reliable placeholder data without setup overhead. The only limitation is that the data resets on the server — no custom data persistence is offered without the sponsor tool Mockend and a dedicated GitHub repo.
