The Free Public-URL Mockoon Alternative

Mockoon desktop is excellent, free, and open source — but it runs on your machine. Getting a Mockoon-hosted public URL means Mockoon Cloud, from $100/month. When you just need one endpoint a teammate, a phone, or a CI job can reach, MockBolt gives you a public HTTPS URL free, with nothing to install.

Frequently asked questions

What is the cheapest Mockoon alternative with a public URL?

MockBolt. The Mockoon desktop app is free and open source but runs only on your machine. Getting a Mockoon-hosted public URL means Mockoon Cloud, whose Team plan starts at $100/month. MockBolt gives you a public HTTPS URL free, and $2 once makes an endpoint permanent.

Does Mockoon have cloud hosting now?

Yes — Mockoon Cloud offers cloud-deployed mocks with team collaboration, and its Team plan is $100/month billed annually with 3 cloud-deployed mocks and 100,000 monthly calls. It is aimed at teams. If you just need one public endpoint quickly, that is a large step up in cost and setup.

Why would I use MockBolt instead of Mockoon?

Because the mock needs to be reachable by something other than your laptop — a teammate, a deployed preview build, a mobile device, or a CI job — and you do not want a tunnel or a team subscription for it.

When is Mockoon still the better choice?

When you are defining a complex API with many routes and want full control offline. Mockoon is open source, supports a real templating engine, detailed route rules, proxy mode, and runs as a CLI server in pipelines.

Do I need to keep an app running for MockBolt?

No. There is no local process and nothing to install. Once you create an endpoint it stays live on MockBolt servers — free for 7 days, auto-renewing while it receives traffic, or permanently for a one-time $2.

Can I create many endpoints at once, like a Mockoon environment?

Yes. Paste an OpenAPI 3.x or Swagger 2.0 spec and MockBolt creates one mock per operation, up to 50 per import.
