01 — Vision
Every small business deserves software as good as the big companies use.
India has crores of shops, sellers and small brands. Most still run on paper, guesswork and tools that were never made for them.
Coding30 builds products that change that: simple enough for anyone, in their own language, at a fair price.
01
Simple for everyone
If a shopkeeper can't use it in five minutes, it isn't finished. Big buttons, plain words, no training needed.
02
Built for Bharat
Hindi and English, works without internet, shares on WhatsApp, and fits how Indian businesses really work.
03
Fair price, real support
Start free, pay only when it helps. Every support message is answered by the people who build the product.
Next: more tools for India's small businesses, each one built end to end.
02 — Products
Two products, two very different customers.
One sells to marketing teams and developers worldwide. The other serves shopkeepers across India, from kirana stores to medical shops. Both are live and open to the public today.
