I left Comet running while I was in a meeting last Tuesday and it renegotiated my internet bill. Not perfectly, not fast, and there's a screenshot of it typing into the wrong Xfinity chat window for eleven minutes at 2:14 PM that I will treasure forever. But it did the thing. And that is roughly the state of agentic browsing in July 2026: it works, it's expensive, most people you know don't use it, and it just drove almost half of all agent traffic on the web.
Which brings the question every founder in my DMs is asking. Should our SaaS site be doing something about Comet? Real talk though, the honest answer is smaller than the number in the headline. Let me walk through what actually shipped, what's about to shift on August 9, and the five cheap moves worth doing this week even if you agree with me that panic optimization is not it.
The Number That Sounds Bigger Than It Is
HUMAN Security's June 2026 agentic traffic report put Comet at 47.6% of all agentic web traffic. That's the headline. Cloudflare's July 2026 bot report confirmed the other headline: automated traffic crossed the 50% line this year, so the majority visitor to your site is now a machine of some kind.
But the small print is where founder decisions actually live. Only about 9% of sites are blocking agentic requests today, up from 8.2% in April, so the blocking curve is real but slow. And more importantly, SaaS accounts for under 1% of the destinations that agentic browsers actually visit. Most of Comet's work is happening on airline sites, insurance portals, government grant listings, and apartment rental portals. Places without APIs. Places a human would rather never look at again. The r/ClaudeCowork thread on browser-agent use cases reads like a support-group survey of what web apps did to us since 2010:
What do you actually use browser agents for?
I've been experimenting with AI agents that can control the browser (clicking, filling forms, navigating sites, pulling info, etc.) and I'm curious what people are genuinely using them for day to day. A few things I'm wondering: What task m...
Grants scraping every other Monday. YouTube video scheduling at 100 clips a day. Insurance quotes across ten carriers. Apartment listings, negotiated ISP bills, timesheet entry inside enterprise tools whose SSO is old enough to vote. This is what agentic browsing actually is right now, and almost none of it lands on a modern SaaS marketing page.
Built by the team that got cited in 48 hours.
Content generation, backlink building, AI visibility tracking, and lead capture. One platform, zero guesswork.
The August 9 Detail Everyone's Sleeping On
Here's the thing nobody's writing about yet. OpenAI is folding Atlas back into ChatGPT and shutting the standalone Atlas browser down on August 9. Atlas was Comet's only real competitor at consumer scale. When it goes, Comet becomes the dominant standalone agentic browser essentially by default, with only BrowserOS's open-source project sitting next to it for the self-hosting crowd. So the 47.6% share is going to concentrate further, not disperse.
Which does not mean Comet has won. Ask the users:
Comet is the best agentic browser I've tried, but the usage limits are a dealbreaker, any alternatives?
I've been using Perplexity Comet for a while now and it genuinely feels like a different league compared to everything else I've tried — the ability to autonomously browse, click, fill forms, and reason across multiple steps without constan...
The title of that post is basically the whole community consensus in one line: best agentic browser they've tried, and the flat-rate usage limits are a dealbreaker. Nobody wants to pay Perplexity's $200-a-month Max tier for unlimited agent runs. And @aakashgupta made the sharper strategic point back in February, which reads even better now that Atlassian just paid a billion for Dia:
Atlassian paid $1B for Dia. That acquisition price tells you everything about where enterprise software value is migrating. The browser that can do your job while you sleep is worth more than the browser that helps you do your job faster. Atlas and Comet are research
Aakash Gupta@aakashguptaFeb 2, 2026Browsers that do your job while you sleep are worth more than browsers that help you do it faster. That's the whole arc of this year's agentic browser wars in one tweet, and it's also why the enterprise pricing pages are the ones actually printing money for these companies.
The Measurement Problem Nobody Warned You About
OK so I skipped over something important. Even if you decided today that you wanted to know how much of your traffic is Comet, you can't. Comet does not declare its own user-agent. It runs on Chromium, and to Google Analytics 4 it looks exactly like any other Chrome session. There's no Perplexity-Comet/1.0 string to filter on the way you'd filter Perplexity's declared crawlers (PerplexityBot for indexing, Perplexity-User for live fetches).
To catch Comet server-side, you're looking at fingerprints: Darwin/CFNetwork user-agents on macOS, missing text-to-speech voice lists, extension manifests that don't match a normal Chrome install, near-zero dwell paired with no scroll depth. It's honest bot fingerprinting work, not a dashboard toggle. If your growth team's measuring "AI traffic" today, they are almost certainly under-counting Comet by looking at it. Not gonna lie, that's how we started tracking AI visibility too, watching it show up as "direct" in every customer dashboard until we realized nobody could see who was actually reading them.
Do You Even Want Comet Agents On Your Site?
Before you optimize, decide the policy question. In November, Amazon sued Perplexity, alleging Comet was logging into Amazon with user credentials to place orders while impersonating a human. The suit is unresolved but the pattern is set: agentic browsers act as the user, not as a crawler, and your terms of service probably didn't anticipate that.
There are three postures now, and every SaaS founder needs to pick one this quarter:
- Allow. Publish clean action-oriented pages, make your pricing table an easy read, add machine-legible content. The upside is being where agents shop.
- Meter. Cloudflare's Pay Per Crawl went into private beta on July 1 and charges via HTTP 402. It's the first serious infrastructure for making agents pay for reads. Cloudflare has also announced a default policy change starting September 15 where mixed-use crawlers get blocked from ad-bearing pages unless the site opts in.
- Block. For SaaS whose value is behind auth or whose ToS forbids agent access on principle, robots.txt for PerplexityBot and Perplexity-User plus fingerprint-based challenges at the edge.
There's no wrong answer here, but there's a wrong non-answer, which is defaulting to whatever your CDN happens to do on September 15.

Five Cheap Moves Worth Doing This Month
Look, the SaaS-founder-should-optimize-for-Comet article you've been dreading is not this one. Here's what I'd actually do this month, in about a workday total:
- Pick your posture on the three above and write it down. It's a slide in a Notion doc. It becomes an org policy the next time legal asks.
- Publish llms.txt and OKF bundles, in that order. Both are cheap markdown overlays, both are speculative, both have zero downside. If Comet or the next four agents that follow it decide to read them, you'll be ready. If they don't, you spent an afternoon.
- Audit your action pages. Pricing, sign-up, calculators, comparison pages. Can an agent complete a task in five steps without a JavaScript modal ambushing it? Because the SaaS that dies to agents is the one with the world's tenth-best onboarding flow that only makes sense to a human clicking through a browser.
- Add server-side fingerprinting for Comet-style traffic. Chromium plus CFNetwork plus zero-scroll. You don't need it perfect. You need enough to see the shape of the trend before the numbers matter.
- Watch the agentic engine optimization space carefully but don't buy the packaged offerings yet. The vendors selling "AEO for AI browsers" today are shipping frameworks for a channel that's under 1% of destinations.
Manual version: two to four hours in week one, an hour a month watching the numbers move. Or the content engine ships answer-shaped pages that already read cleanly to agents, and our tracking watches AI-referral shape shifts weekly, so the day SaaS becomes 2% of destinations you know before your quarterly review.
Your competitors are building backlinks while you read this.
Organic outreach, social mentions, exchanges, and done-for-you link building. Four ways to grow your domain authority on autopilot.
The honest read on Comet is that it works, its user-agent doesn't work, its pricing doesn't work, and it's about to be the last man standing. That's a lot of "working" pointed at a channel that hasn't come for you yet. Cheap prep, no panic, and go negotiate your own ISP bill by hand this month. Get in one last human win before the agents get faster than eleven minutes.
