Deploy Smocker in one click installation.
Simple and efficient HTTP mock server and proxy with a built-in admin UI for testing and debugging APIs.
What you can build with Smocker
Smocker is an open-source HTTP mock server and proxy built for engineers who need realistic, deterministic API responses during development and testing. Developers define mock endpoints declaratively in YAML or JSON, replay scenarios, and inspect every incoming request in a live admin UI without writing any glue code.
Self-hosting Smocker on your own VPS gives teams a shared mocking environment for integration tests, contract verification, and demos, with full control over network access, recorded traffic, and uptime guarantees that public mocking services cannot match.
Key features of Smocker
Declarative mocks
Define HTTP responses in YAML or JSON with request matchers, dynamic templates, and ordered scenarios for predictable test runs.
Live admin UI
Inspect every incoming request, view matched mocks, and reset state from a browser-based dashboard built for fast feedback loops.
Proxy and record
Forward unmatched requests to a real upstream and capture the responses as reusable mocks for offline testing.
Sessions and history
Group calls into named sessions to isolate test runs, replay traffic, and compare behavior across releases.
REST API control
Manage mocks, sessions, and history programmatically from CI pipelines using a complete REST API.
Lightweight container
Single Go binary packaged as a small Docker image starts in milliseconds and runs comfortably on any VPS plan.

I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.
Everything is smooth and great with Hostinger, the AI chat bot + human chat, if AI can't resolve your question. Oh and them VPS is just fire, no ups and downs. Thank you dev team and everyone else involved. Keep it up 🚀
Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Hostinger Agent and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
