A product name that fires a shot.

I wonder if the folks at Cursor feel called out, or just glad that they're big enough to be perceived to be a threat.

Not sure, but I struggle with skepticism for anyone who blocks archive.today, which cloudflare does, along with nextdns and others. Being blocked by such a large... apologies in advance for 'lack of better word' vernacular, cartel, is a near death sentence.

Not a fan

Cool product launch, though it feels a little weird to me that Cloudflare sells agentic products alongside this new service that seems designed to block agentic usage of the web?

I expect there's much more going on than just mouse path detection but I can imagine that this is already tricky for touchscreens and for people using non-traditional mouse inputs (the thinkpad nub comes to mind - but it would also be bad optics to accidentally block people using accessibility mouse tools as bot users, though then this becomes a loophole for agentic browsing!)

In general though I think this is almost definitely a good thing to reduce agentic bot abuse & spam.

skybrian•16m ago
It’s less weird if you think there’s a difference between good bots and bad bots. They can provide services for good bots to use while helping people keep out the bad ones.

If a bot is simulating mouse movement but doing it badly then that’s a strong signal of shenanigans. A good bot will obey robots.txt and do nothing to hide that it’s a bot.

Who gets to decide what is a good bot?

Feels a little bit like the mob selling "protection" to shop keepers.

What prevents bots/agents from just adding "jitter" to their movements that mimics how humans move their cursor?

I know there are other signals being used but this one in particular seems like it wouldn't be hard to beat with a small amount of sophistication from the bot.

stogot•15m ago
In 2027 how many tokens will we spend to create the jitter, pre-jitter planning, post-jitter verification, and then cloudflare’s inevtiable counter-jitter

Someone needs to vibecode a "virtual mouse" tool for the agents to steer instead (semi /s)
kypro•13m ago
There's always been an arms race in anti-bot technology and more sophisticated bots.

I'm sure, they can add a jitter, but then you just change how you detect / weight detection.

fwlr•12m ago
The jitter you add has to specifically be “jitter that mimics human cursor movement”, which is extraordinarily non-trivial to synthesise.

how does this interact with keyboard navigation & accessibility tools?
Havoc•17m ago
It’s a bit alarming how cloudflare is establishing itself as arbiter of all things bots…both on blocking and allowing.

Doesn’t seem healthy for the internet as a whole

jppope•16m ago
Agreed, but we should be honest, the internet today is far from healthy
ianm218•10m ago
For any one of their product there is a good opportunity to build an open source alternative or something like it! Can be hard to work around they have the benefit of being able to have negative unit economics on lots of infra products... But people succesfully built tons of alternatives to google analytics and similar.

Yes, but it’s up to their competitors to build competing services.

I can’t wait for cloudflare to sell data on how well my wrist is working to my insurance company. What a wonderful hell we’ve created for ourselves.
freedomben•12m ago
As a real user who uses an Ultimate Hacking Keyboard with the mouse layer, this frustrates me immensely. Yes I'm a corner case, but this is likely to make certain website not work for me because my lines are perfectly straight and my arcs zig-zag much like a bot might.

Considering the keyboard/mouse layer feels like an advancement to me, this feels like tech that will lock in the "old" way of doing things.

I really detest how adversarial the web is getting. I'm not a cloudflare hater but please, please consider people like me when rolling out stuff that affects millions or maybe even hundreds of millions or billions of people.

akersten•12m ago
control+F accessibility no results

Yeah so this mouse movement astrology is going to completely lock non-sighted/keyboard only users out of large swaths of the Internet isn't it.

sudb•5m ago
I'd imagine that mouse movement is just one signal among many that's weighted appropriately, but I hope we get feedback from these users
abirch•5m ago
I'm guessing it's going to lock the non-sighted//keyboard only users out of the anonymous Internet. I'm guessing if you log in and give up your anonymity they'll consider you not a bot.

Apart from handling of abuse reports. Yeah we're acting as CDN for this phishing site - we'll just inform the upstream about it and do nothing.
