Launched Numbo – A Free Tool to Extract & Save WhatsApp Contacts Without Extensions or Apps
Hey Indie Hackers 👋
I'm Ameer, and I just launched a small tool called Numbo to solve a frustrating problem I kept facing while running WhatsApp-based lead campaigns.
If you’ve ever run Facebook or Instagram ads where people DM you on WhatsApp — you probably know the struggle of saving unknown numbers one by one.
I tried browser extensions and mobile apps to fix this, but:
They asked for too many permissions
Some slowed down my browser
A few even triggered warnings from WhatsApp
Most were either filled with ads or just unreliable
So I built Numbo, a lightweight web tool where you can:
✅ Upload a screenshot from WhatsApp Web
✅ Extract all unknown numbers instantly
✅ No logins, no installations, 100% browser-based
✅ Works on mobile and desktop
✅ Completely free
I made it for myself first, and then a few agency friends tried it and loved it — so now I’m opening it up for others too.
Would love your feedback — feature ideas, bugs, UX suggestions — anything helps.

Hey webtoolsbyai
Just came across your product Numbo have to say absolutely loved the idea and execution. I'm a designer who’s worked on [Logo/UI/Landing page etc] For multiple brands.
Had a couple of small ideas that could instantly improve your [branding - i.e. Logo Design].
Would it be cool if I shared them with you?
No pressure at all — I just want to add some value.
It's very nice, congratulations
