Show HN: I built a SaaS for generating mock APIs (Django and React, 2.5 months)

https://mockmydata.io
1•marcuscodes•2h ago
Hi HN! I built MockMyData.io - a tool that lets developers generate mock REST APIs.

The problem: When building frontends, I didn't want to hardcode JSON data everywhere. I wanted to build against actual API endpoints and practice the integration work, but spinning up a real backend for every prototype felt like overkill.

Tech stack: Django backend with PostgreSQL and Redis caching, React frontend, multi-tenant architecture with subdomain routing. Built the entire thing in 2.5 months as a solo developer as well

Link: https://mockmydata.io

I Would love feedback on how to improve it!
