Decoy lets developers create mock services locally. No need for Docker or heavy Electron apps. I built it to test webhook requests coming from my own applications, testing my API wrappers and seeing how my app reacts to redirects, timeouts and failures. You can even mock full webpages to test your scrapers and AI agents against, without risking being rate limited or blocked. All in a beautiful native app. It weighs only 10MB and starts up super quickly and there is no tracking at all.
I was building a webhook feature into my SaaS and I wanted an easy way to see what the requests would look like on the receiving end and to test what would happen if the target system gave back errors, took too long, redirected, etc.
I found several tools to do this, but all of them were either expensive, bloated with other features, required me to create accounts and had subscriptions or were heavy Electron apps.
Why isn't there an easy to use, lightweight, native app to do this? So I decided to build Decoy. All for one lifetime price.
I kept adding features such as code highlighting, redirects and other things I liked and then I decided to share it with the world.
I hope you enjoy it and find it as useful as I do.
