The browser wars are back.

Comet and Dia showed up out of nowhere.
Chrome and Edge are now pretending they’ve always been “AI-first.”
Brave, Arc, and twenty other indie browsers are all clawing for a piece of that sweet, sweet market share.

But last week a new one popped up. At the hype was the most.

ChatGPT Atlas entered the scene.

And it’s coming straight for Chrome’s throne (but it’s built on chromium).

Before we dive deeper, here’s what happened this week:

1. Metorial: Integration Gateway for AI Agents

Open-source framework that lets AI agents connect with 600+ tools, APIs, and data sources out of the box. Designed for developers who want to deploy agent workflows on serverless infrastructure with full observability. Includes Python and TypeScript SDKs and supports self-hosting for tighter control.

2. Velona AI: Agentic Platform for Fleet Operations

Purpose-built AI system that connects directly to telematics and OEM data feeds to predict failures, flag risk, and identify hidden costs before they appear. Built on Databricks and tuned for real-time analysis, Velona showcases how domain-specific agents are moving beyond chat to actual operational decision-making.

3. Browserbase: Headless Browsing Infrastructure for AI

Developer platform that spins up and manages real browser sessions programmatically. Enables agents to crawl, log in, extract data, and perform web tasks safely at scale. Works with Playwright and Puppeteer, giving teams a reliable backend “browser layer” for automation and agent testing.

Perplexity’s been poking at Google for a while.
First with search, now with browsers.

Comet launched quietly a few months ago, built on Chromium but wrapped in an agentic core that actually does stuff.

Then came Atlas from OpenAI. It looks sleek (i love it), ChatGPT sits right inside, and wants to handle your browsing, searching, and prompting from one place.

I spent a week using both as my daily driver.

Here’s what happened.

I was writing to a startup founder, asking for a guest session for our program.

Atlas:

It writes well.
The speed is meh.
It took forever to write a subject line.
When it did, it was like chatgpt 3…

But when I asked it to “rewrite this email in 110–130 words, tone: warm, credible, outcome-focused,” the result was pretty decent.

Minor edits, and it was ready to send.

Comet:

Slightly slower. The tone was fine, but it lacked the finesse that Atlas had.

Winner: Atlas.

Mostly for the experience. I actually said “whoa” out loud the first time it worked.

Festive season is over, but capitalism isn’t.

i wanted to see who could find me a better deal.

Both took their time.

Both found better codes than what I had available on the website.

Atlas applied one automatically, then upgraded it when I asked.

Comet skipped the warm-up and hit me with the best code right away.

Although it did what all of us probably are guilty of doing, was a nice touch.

Winner: Comet.

Faster, cleaner, less chatty.

You remember a random clip from a podcast, you’re offline in the hills, and you just want that one minute in a 1-hour podcast.

Atlas took me to Lenny’s website, found the transcript, and stopped there.

When I said “no, take me to the actual clip,” it figured it out instantly.

Comet stayed inside YouTube.

It literally scrubbed through the video like a human, jumped back and forth, and landed on the exact timestamp.

Winner: Comet.

A little slower, but way more satisfying to watch.

I was looking for engineers who worked at Razorpay and are now open to work.

Atlas took a bit longer but found good matches.


Then it told me I’d need Premium to message them and suggested sending a connection request instead.

Comet found the same person, realised I couldn’t message them, and immediately looked for a first-degree connection I could reach out to.

Then it opened the message composer automatically.

Winner: Comet.

That’s actual initiative.

Comet runs agents automatically.
You search, and it just starts thinking.

Atlas needs you to switch on “Agent Mode” every time.

Slightly annoying, but fair.

Sometimes you just want a search, not an overachieving intern taking notes.

In either case, no setup required, except maybe staying logged into the sites you regularly visit.

Here’s the scoreboard so far:

Both feel lighter than Chrome despite all the AI packed inside.

That’s the biggest surprise.

These aren’t bloated tools trying to impress you.

They just... work.

Comet feels like an assistant that reads your mind but doesn’t talk too much.

Atlas feels like an assistant that wants to talk about your feelings first.

If I had to guess how this plays out, Comet will keep its early-mover speed while Atlas catches up through sheer momentum and OpenAI executing relentlessly.

How quickly will they change how we surf the internet?
Only one way to find out.

Because once your browser starts writing your emails, fetching YouTube clips, and finding people to hire, there’s no going back.

So, which one are you switching to this week?

Until next time,
Vaibhav 🤝🏻

PS: both are free to try. Atlas is giving boosted credits if you set it as your default browser for a week. Comet’s paying a dollar for every friend you bring. Capitalism wins again.
