Build a small paid plugin for software you use daily

How it works

Every big platform with a plugin ecosystem has thousands of users hitting the same small annoyance. If you're already a user and a programmer, you notice it first. You build the smallest thing that fixes it, list it in the marketplace with a clear name and a thirty-second video, and price it at what a professional would pay to stop being annoyed. Marketplaces bring the search traffic; reviews and updates keep it selling.

What it actually takes

• Programming ability in the platform's language and familiarity with its plugin API.
• Being a daily user, so you know which annoyance is real and shared.
• A support habit: answer every message, fix every bug, publish a changelog.
• A name people would search for. "Bulk rename layers" outsells anything clever.

Where it goes wrong

• Building something big. The first plugin should do one thing, take a few weeks, and ship.
• The platform ships your feature natively. It happens. Ship fast, price fairly, move on.
• Ignoring support. Marketplaces rank by reviews; unanswered reviews kill listings.
• Free-only ecosystems. Some platforms' users won't pay. Check whether paid plugins actually sell there before you start.
