the flywheel in motion making Cloudflare OS better each day is amazing right now. see note from principal engineer below.
1) move more workloads to Cloudflare OS
2) send feedback on what needs to improve
3) product improves to the point that it "honestly changed our lives after just a few hours of work"
4) repeat

Container's new runtime again showing up in benchmarks, and we've already gotten better w/ new updates since bday week
P95 is 731ms now, down ~180ms from 2 weeks ago at bday week

Cloudflare is an infrastructure company. In 2026 that means the best place to run code and the best tools to build and ship it. Agents are writing more of the code every month. Someone still has to make it build and run.
This has been a big year of investment to make us even better.
We added @evanyou wrote Vue and Vite and @rough__sea wrote Node.js, then Deno.
Helping to make “Deploy to Region: Earth.” the agent default.

We built a new runtime and scheduler for Cloudflare Containers. It can start ~18.5k Containers per second.

We spent the last few months reworking our containers runtime and scheduler to fit the agentic sandboxing use case. Lots of fun low level systems engineering went into this one. Cold starts are much faster, you can burst way harder, and filesystem snapshots are available.
Cloudflare Containers now start 6x faster, let your agent choose each sandbox's image and instance type at runtime, and support filesystem snapshots in public beta, all controlled from a Durable Object. cfl.re/4hVasac #BirthdayWeek

Working with the team on this is my fav ship at Cloudflare. Sandboxes now scale to 100k+ starts/s, <1s cold start, dynamic image & resources, disk snapshots, and programmable egress interception.
And all of it from your Durable Object : ) Alongside Dynamic Isolates if you wish

filesystem snapshots
~650ms TTI
dynamic instance sizes
no SDK, zero dependencies
we rebuilt Cloudflare containers to use the full power of Durable Objects

biggest containers update since launch just dropped. and it's all about agents sandboxes
new scheduling policy, new runtime, 648ms median startup, runtime image selection, filesystem snapshots (!!), sandbox sdk 1.0
there's a lot in this one 1/ 🧵

We rebuilt Cloudflare Containers for agents — TTI is 6x faster with p50 at 648 ms — and we shipped Snapshots in beta

I feel very lucky to be sitting at a very exciting frontier at Cloudflare. It can be hard to discern noise and reality in Silicon Valley. But the work we're doing on agent payments is real, and we're building it together with the best partners in the industry.
We have so much work ahead of us, and I'm more excited than ever.
The logic that orchestrates your compute rarely shares the same resource requirements as the compute itself. Do you really need a giant box to do inference with a model provider? Or do you just care about the big box when you’re compiling or running tests? This pattern extends to many different use cases.
We’re working really hard behind the scenes to make durable objects and containers work seamlessly together as compute primitives. Colocating DOs and containers is just one example of this. Dehydrating and hydrating disk quickly, scaling up resources programmatically, and integrating well with all of the goodies Cloudflare’s developer platform has to offer will make agentic compute just make sense.
Computer is one of those ships that I am truly excited about - and while it looks like we just glued a Durable Object and a Container together, making this work is what we've been building towards for so long.
It lets your Agent run in an incredibly efficient, durable environment while delegating all of the heavy lifting to a container. If you've ever tried to separate your agent harness from your sandbox , you know how tricky it is to keep their states in sync especially when something crashes.
Computer lets you avoid the complexity, and why it works is the most interesting bit. We actually attach a private container to your Durable Object, allowing it to share the same underlying DO storage via a custom FUSE filesystem.
At first this looks a bit like network attached storage, and it is - but next up we're going to ensure that your Durable Objects and their container side cars are co-located on the machine, allowing shared access to be blazing fast.

Agents need more than just a container to scale. We're introducing @cloudflare/computer, an agent runtime that dynamically orchestrates between fast, efficient isolates and full Linux containers to give every agent a computer of its own. cfl.re/4w8H8AN

We are launching Workers Cache, a regionally tiered cache that sits directly in front of your Worker entrypoints. Infinitely composable, configured via standard HTTP headers. cfl.re/44IVyfI

fokosdb is probably the thing i’m most excited about in cloudflare ecosystem atm
what is it?
what if dynamodb, but cloudflare

Excited to launch Claude Managed Agents on Cloudflare today!
- Run sandboxes as microVMs or even lighter-weight isolates on CF
- Zero-trust creds injection, custom egress proxies, better observability, private services via VPC
- Agent Email + Browser Run + easy custom tool calls

built on @cloudflare sandboxes 🔥
For the past several months, our engineering team has been building a new agentic coding system designed around a simple idea: the self-driving codebase.
These aren't just agents to write code on demand. They detect triggers, spin up secure sandboxes, gather dynamic context, open PRs, verify their work, unblock the next task, and learn from every failure.
We think the future of software engineering may look more like swarms of event-driven agents, running continuously, with humans setting direction and reviewing the work.
Ramp built Inspect. Stripe built Minions. Spotify built Honk.
We call ours Horizon. 🌅

Cloudflare Sandboxes now do secure credential injection.
We use Workers as a trusted proxy, which make it really easy to customize egress policies (globally or per-instance) and update them dynamically. Let's take a look...
Inject a token without the agent ever seeing it:

Sandboxes and Containers now support secure credential injection and dynamic egress policies. Upgrade to [email protected] or [email protected] to keep secrets out of your agents and control outbound traffic.
