Comparison
Ocular vs Chrome DevTools MCP
Looking at a web page should feel like part of your AI, not a tool it has to go and fetch. Ocular is quiet, quick, and gives your AI the picture, the page layout, the styles and the images from one place.

- Pick Ocular if
- you want looking at a page to be something your AI just does. No window on your screen, nothing to babysit, and the picture, the page layout, the styles and the images all from one place.
- Pick Chrome DevTools MCP if
- you want your AI to drive a browser. Clicking the buttons, filling in the forms, and watching what happens when it does.
The best tools are the ones you stop thinking about
Your AI does not ask before it searches your files. It just searches. You never think about it.
Looking at a web page should feel the same. Usually it does not. A browser window pops up, your taskbar fills up, and you end up keeping an eye on a second program that is meant to be helping.
Ocular is built so you stop noticing it. You set it up once. After that, your AI looks at web pages the way it reads files: whenever it needs to, without asking you.
Ask for a page, get what you need back
The picture comes with a map. Every time your AI looks at a page, it gets the page the way it really looks, plus a plain list of what is on it: what you can see right away, what you would have to scroll to reach, and where each thing sits. Your AI does not have to guess where the button is. It knows.
You choose how it looks. Pick the screen size. Pick how sharp. Pick the part you can see, or the whole page top to bottom.
The styles are one ask away. The colours, fonts, spacing, corners and shadows the page really uses. Handy when you are matching a design, or working out why two things that should look the same do not.
So are the images. The icons, logos and drawings on the page, pulled out and ready to use.
All of it from one tool, set up once.
Moving things come back as one picture
Claude cannot watch video. Show it a moving image and it sees the first frame and nothing else.
So Ocular lays the frames out side by side in a single picture. Your AI sees the whole movement at once, and it costs no more than any other picture.
It stays out of your way
No window. No icon in your taskbar or dock. Nothing to close when you are done.
It gets ready the moment your AI connects, so the first look does not wait for a browser to start. When you stop using it for a while, it shuts the browser down on its own and drops to about 10 to 15 megabytes until you need it again.
Chrome DevTools MCP opens a real Chrome window on your screen unless you change a setting to hide it. That makes sense for a tool meant to drive a browser while you watch. It is a lot of screen for something you only want to look with.
It gets into sites that turn robots away
Lots of sites block anything that looks like a program instead of a person. Point an ordinary tool at them and all you get back is a “prove you are human” page.
Ocular gets through most of those. Most, not all. The bigger plan reaches further into the stubborn ones. For everyday pages, like a rival’s pricing or a guide you are building from, your AI can usually just see them.
It looks. It doesn’t touch.
There is no clicking, no typing, no jumping to another page. Not switched off. Simply not built.
So nothing can go wrong by accident, and there is nothing for you to turn off. It also means Ocular is the wrong pick if you want your AI to click through a checkout and tell you what broke. That job needs a tool that can press the buttons.
Anything that can change a page can also break one. That is just what that kind of tool is for. It does not make one safe and the other not. Whatever either tool sees goes straight to your AI.
| Ocular | Chrome DevTools MCP | |
|---|---|---|
| Picture and page map | Together, every time | Separate steps |
| Window on your screen | None | Yes, unless you change a setting |
| Can it change the page | No | Yes. Clicks, types, fills in forms |
| Price | From $2.50 a month | Free |
What it costs
A few lines in a settings file. Nothing else to install, and nothing to look after once it is going.
$2.50 a month. No limit on the site running on your own computer. On the wider web you get 40 page views a day, because that part runs on servers that cost money to keep going.
The short version
A tool you have to think about is a tool you stop using.
Ocular gives your AI eyes that feel built in. The picture and the page map together, the styles and images when it needs them, no window, and it gets into most sites that turn robots away. It looks, it does not touch. Set it up once, then forget it is there.
$2.50 a month.
If what you use today already does all of this, and you haven’t had to fix it in six months, you don’t need this.
