Most Chrome extensions die as “someday projects”. Kromio wants them shipped.
You’ve had the idea.
A little widget. A scraper. A page tweak that saves you ten clicks a day. Then you open the docs, stare at Manifest V3, fight permissions, and the thing never leaves your notes app.
Here’s the deal: Kromio (kromio.ai) turns a sentence into a Chrome extension you can run in minutes. No setup marathon. No boilerplate grind.
What you actually get
Kromio.ai generates the full extension package: the manifest, popup UI, scripts, and the wiring that makes Chrome accept it.
You download a ZIP.
Load it in Chrome dev mode.
Test it on the page you care about.
That’s the loop. Fast.
Built for iteration, not perfection theater
Most builders spit out code once, then leave you holding the bag.
Kromio.ai bakes in a revision flow so you can say “change the layout”. “add a toggle”. or “only run on these domains”. and keep moving.
It gets worse if you do this by hand: each tweak can break permissions, content scripts, or the popup.
Kromio aims to keep the structure sane while you poke it.
Why founders and indie hackers care
Extensions work like tiny products.
They sit inside someone’s day. They solve one sharp pain. They can become a lead magnet, a paid utility, or a wedge into a bigger SaaS.
Kromio.ai leans into that reality:
- Prototype speed: minutes instead of “next weekend”.
- Store-ready structure: manifests, icons, and the stuff Chrome Web Store expects.
- Compliance-minded defaults: Manifest V3 and basic security hygiene so you don’t ship a privacy nightmare.
What people build with it
The site calls out the usual winners:
- Productivity helpers (notes, timers, quick actions)
- Web scrapers (research, monitoring, extraction)
- Page modifiers (hide junk, restyle, filter)
- API tie-ins (dashboards, CRM glue, analytics views)
But there’s a catch: the best extensions don’t try to do everything.
They do one job.
They do it well.
The real pitch
If you can explain the extension in plain English, you can test it today.
And if it works, you didn’t just “learn Chrome extensions”. You shipped.
That’s the point.
