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!🚀
