Most devs handle software licensing wrong — here is the right way

Most devs selling software handle licensing like this:

Store a key in a database
Check it manually
Hope nobody shares it

It works until it doesn't. One shared key, one angry customer,
one manual reset too many — and you realize you needed a real
system from day one.

KeyPort handles all of it properly.

Generate license keys from your dashboard. Validate them in
one API call from inside your app. Set activation limits so
one key cannot be used on 50 machines. Add expiry dates.
Block specific IPs. Let your customers manage their own keys
through a self-serve portal so they stop emailing you.

Everything you should have had from the start.

Free tier: 10 products, 200 licenses, 10,000 API calls per day.
No credit card. No time limit.

I built a license key API for developers who sell software

If you sell a plugin, desktop app, theme, or any software —
you know the moment.

Someone buys your product, switches machines, and emails you
asking to reset their license. You dig through a spreadsheet
or a database you hacked together and fix it manually. You
tell yourself you will sort it properly later.

Later never comes.

I built KeyPort because that problem deserves a real solution.

KeyPort lets you generate license keys, validate them in a
single API call, set activation limits, expiry dates, and IP
controls. Your customers get a self-serve portal to manage
their own keys — so they stop emailing you.

Free tier: 10 products, 200 licenses, 10,000 API calls per day.
No credit card. No trial period.

SDKs available for Node.js, Python, NestJS, Express, and Java.

Just launched today. If you have dealt with license management
before and have feedback — I genuinely want to hear it.
