What inspired you to build this?
My laptop fan. Seriously.
Postman would spin up and my CPU would spike before I even made a single request. I'm running a decent machine and an API client — something that sends HTTP requests — was eating memory like a browser with 40 tabs open. It would hang mid-session, slow down my whole system, and somehow still ask me to log in on top of all that.
I started timing it. Postman took longer to load than my actual backend server. That felt wrong.
What problem were you trying to solve?
REST clients have gotten bloated. What started as simple tools to fire HTTP requests have become cloud platforms with Electron apps that feel heavier than the services they're testing.
The core problems I kept hitting:
CPU & memory hog — Postman regularly used 500MB+ just sitting idle. On battery, it was a death sentence.
Hangs mid-session — right when you're deep in debugging, the app freezes. You lose context, you lose flow.
Forced cloud sync — everything trying to phone home, even when you don't need it to.
Login walls on basic features — collections and environments shouldn't require an account.
RestForge is built to be light, fast, and stay out of your way. It loads in under 2 seconds and stays there.
How did your approach evolve?
Performance was the non-negotiable from day one. Every feature had to earn its place without adding weight.
I kept asking — does this need the internet? Does this need to run in the background? Does this need to know who I am? If the answer was yes to any of those, I cut it or rebuilt it differently.
The VAPT tools, Git integration, terminal, 15 plugins — everything ships inside the app but only activates when you use it. Nothing runs idle in the background taxing your CPU.
The macOS build is still in progress but Ubuntu and Windows are live. Shipped early because I know developers will tell me exactly what's still slow — and I want to fix it.
Why this framing works better:
The CPU/hang pain point is visceral and universal — every Postman user has felt it. Leading with "my laptop fan" is a detail people will nod at immediately and it makes the whole answer feel genuine rather than scripted.
