> Our technical infrastructure is our secret weapon. We're built from the ground up on Cloudflare's global edge network using reactive systems and local-first architecture. With modern, secure network protocols, we've reduced infrastructure costs by 100x compared to Slack or Teams. Their systems were built over a decade ago on legacy infrastructure that can't be easily modernized. We started fresh—and pass those savings directly to you.
...but this doesn't pass the sniff test. Cloudflare's products are value-add on value-add, they're a long way from raw infrastructure costs. At a small scale the fact you can pay as you go might mean they're cheaper than VMs or machines to get a good UX, but at scale they're hugely expensive.
Their technical infrastructure sounds like their Achilles heel in the long run.
I appreciate the skepticism—usually 'Managed Platform' does imply a heavy markup over raw compute. But for a chat application specifically, the math leans heavily in favor of Cloudflare Workers (Isolates) over traditional VMs/Containers.
You mentioned scale: Cloudflare's free tier covers the first 100k requests/day, but the paid tier is where the economics really shine at scale. We pay roughly $0.30 per million requests
In the traditional architecture (Slack/Teams), you pay for provisioned capacity to handle peak load. That means you are paying for massive EC2 clusters and RDS instances 24/7, even when usage dips at night. You pay for the idle time.
With Cloudflare Workers, we pay strictly for execution time. Chat is incredibly bursty and text data is small. If no one is typing, our infrastructure cost is literally $0. We don't pay for idle CPU.
Even at scale, the cost of executing a Worker for a few milliseconds to route a JSON packet is significantly lower than the Total Cost of Ownership (TCO) of maintaining a global fleet of VMs, load balancers, and a DevOps team to manage Kubernetes. We trade 'raw metal' efficiency for 'operational' efficiency, which is where the real savings are
