Hey Devs! 👋
I built MockAPI Dog to solve a problem I constantly ran into as a developer: needing APIs that don’t exist yet - or needing to test weird edge cases and errors quickly.
MockAPI Dog lets you instantly create mock REST APIs and even mock streaming LLM endpoints (like OpenAI-style or Claude-style) without creating accounts, writing backend code, or managing keys!
It’s completely free and designed to get you unblocked fast.
Would love your feedback and feature ideas! :)
PS: I'm doing zero paid promotions and no random spamming on Reddit or Twitter. I hope people upvote if they find this tool useful.
The dog branding alone got me clicking lol. I'm building a pet tech app so totally unrelated, but as a dev this is genuinely useful — mocking LLM streaming endpoints without burning API credits is a huge time saver. Nice work and congrats on the launch!🚀
@go_sakioka Thanks a lot, Go! :D Yeah, it was nice flexing my design muscles by making the mascot in Figma :)
Trier to use it, really useful.
Do you plan add more protocols and features?
LLM API mocking is clutch. I burn way too much testing prompt variations during development - having instant mock responses would've saved me hours (and dollars) on VibeCheck. How do you handle streaming responses? Most LLM APIs stream tokens, curious if your mocks support that or just batch returns.
