The Hosted json-server Alternative

Love the idea of json-server but tired of npm install, a db.json file, and a terminal running on localhost? Paste your JSON into MockBolt and get a live, public HTTPS endpoint in seconds — reachable from any app, teammate, or CI job. No Node, no local process, no signup.

Frequently asked questions

What is the best json-server alternative that needs no install?
MockBolt. Instead of running npm install -g json-server and maintaining a db.json on your machine, you paste JSON in the browser and get a live public HTTPS endpoint in seconds. No Node, no local process, no signup.
Why would I switch from json-server to a hosted mock?
json-server is great for local-only development, but it stops being convenient the moment you need the mock somewhere other than your laptop — a deployed preview, a teammate's machine, a mobile app, or a CI pipeline. A hosted endpoint is reachable from anywhere with no tunnel or extra hosting.
Is MockBolt a drop-in replacement for json-server?
For serving mock responses, yes — paste the same JSON you would put in db.json and you get an endpoint. The difference: json-server gives you full REST CRUD backed by a file, so POST actually persists. MockBolt returns a fixed response per endpoint and simulates writes, plus adds custom status codes, response delay, error simulation, and a live request inspector.
When is json-server still the better choice?
When you specifically need stateful CRUD during local development — creating, updating, and deleting records that persist across requests against a local file. That is json-server's core strength. If you just need a reliable endpoint that returns known responses, a hosted mock is faster and shareable.
Do I need to keep a terminal open for MockBolt like I do for json-server?
No. There is no local process. Once you create an endpoint it stays live on MockBolt's servers — free for 7 days, auto-renewing while it gets traffic, or permanently for a one-time $2.
Can I try it without pasting my own data?
Yes — MockBolt hosts ready-to-use sample endpoints for users, posts, todos, and products, similar to JSONPlaceholder. Hit them immediately, or paste your own JSON for a custom endpoint.
