CloudflareOS is everything that you wish Google Workspace could do well, but can't
just went from data question to spreadsheet to pricing memo with a real-time editor in one browser tab
then sent someone on my team a link to all of it (including original prompt) — we can both keep prompting and make direct edits
all of this is possible to get done with codex/claude via computer use and integrations — but i am telling you it is night and day faster this way, and I don't worry about security/permissions at all because cfos makes the footguns impossible, in a way nothing else can
what starts out as a toy...

with products and people — always get on slope, not y-intercept
one of the superpowers of cloudflare is our ability to move fast and iterate quickly once we set our mind to solving a problem
cloudflare has been getting polished lately. just migrated 2 simple sites i've had from vercel to cloudflare and it was a breeze.
love this little motion for progressing through a flow (and it lets you go back by clicking on the previous step that's hovering up at the top too)

Is it wrong that I love being back at a job where people actually use mtr? The network geek in me is losing it.😅

"Here's the pitch for Workers, minus the marketing:
You write a function. It runs in 300+ cities. You never order a VM. You never create a subnet. You never file a ticket to yourself."

AI agents don't just reason anymore. They transact. Cloudflare's Monetization Gateway lets content owners, API providers, and MCP servers charge agents directly, per request, using x402. And today, enterprises building agents with @AWScloud AgentCore Payments can tap into that supply from day one.

Thank you for coming to my TED talk.
was very cool to see this project from the sidelines.
now runs on workers!
This was fun. We took a look at who has adopted RFC 9234 for route leak prevention. It isn't as simple as just tracking the OTC, but our global peering made it a lot easier.
We also found some networks unexpectedly stripping the OTC.
