Running a VM does not a sandbox company make. You need to have private networking, an incredible SDK, native agent integrations, tracing, secrets injections, and a whole host of other features. Running the VM is the easy bit.
Paul Butler@paulgb

@HeyGarrison In the future everyone will have a sandbox company for fifteen minutes.

I just read this conversation. I love your take and I think you’re completely half right. What I agree with: Agent in VM vs outside isn’t a serious debate, it’s a skill issue. The agent could be in china and the sandbox in SF and the latency would still be sandbox operations and tokens. Durable Streams are the correct architecture for agents. This is an architecturally solved problem, but existing solutions aren’t practical. Companies like electric, s2 cc @sgbalogh0 and Cloudflare are going to solve it and agents in VM will die as headless harnesses become more common. Where I think you’re wrong: Every one of those thousands of sub agents is gonna want a 64GB RAM workbench to try its ideas out. Anything less than this is wasteful. We don’t give junior engineers chromebooks, and agents are smarter than them. I think there is a false belief we have been taught that we have to build minimal systems/use less resources to make stuff work efficiently which automated intelligence breaks, the value of increasing its capabilities trumps all else. [this is also why I don’t believe in small models] I can’t speak for every sandbox company, but I think the promise of sandboxes is that the tech to actually provision the computers that go with your streams efficiently is not built yet, I’m working on it ;)

1. The world needs managed agents. Every major platform shipped one in the last six weeks — Anthropic, Cloudflare, OpenAI, Microsoft, Amazon, Google, LangChain. The demand is real and the consensus is set. 🧵

The real ones get it. Of the 500 new sandbox companies, there are ~6/7 real ones. Diptanu is a real one.
Diptanu Choudhury@diptanu

The first MVP is easy. Doing at scale is a hard software problem. After that delivering performance for snapshots, restore, file system is even harder. Assuming you have done all of the above, the next step is capital intensive - getting enough compute for on demand usage.

No argument from me that creating network namespaces takes time! But your assumption that you can’t create them all in advance tells me you haven’t seriously tried to optimize your systems yet. Trust me, you can do the whole thing much faster without losing out on performance. This is why I keep saying the sandbox providers aren’t even at the starting line yet. There’s so much left to do!

Please don’t assume what we do or do not do lmao, we’ve been running VMs long before you guys existed. We absolutely setup network namespaces and cgroups and chroots. And we do not mmap. In fact, unlike all cloud hypervisor users, when we restore from a snapshot we don’t reuse the same crypto random seed.

you: 1. have high IO local storage, atleast 100 GB to store a couple 2. store the VM memory serialized 3. mmap (preferably with an index of pages to explicitly fault/using huge pages). 4. run your command over vsock instead of gRPC/anything that hits the real network stack You don't: 1. set up a fresh network namespace/real networking: minimum 10-20 milliseconds 2. create cgroup per vm + create a chroot + mount everything in it to work + explicitly clear all environment variables given from parent process [all the things required to do a secure hardware virtualized machine] another 10-45ms.

@benswerd Not sure this is the best take. Being able to start a real Ubuntu box and have a netcat process listening and able to accept connections in 1ms requires deep research and understanding of how every part of the VM works. Being able to do this is the sign of deep understanding.

@benswerd for your deployment app: freestyle.sh/products/deplo… you say: Serverless TypeScript deploys for AI agents our customers want a fullstack deployment. Serverless deploy makes me think this is a lambda competitor. Can i host any arbitrary typescript app on your service?

Sandboxes don't do hardware virtualization Sandboxes don't support docker in docker Sandboxes don't have fast IO Sandboxes prioritize fast startup time over overall functionality Sandboxes cap out at 8GB of RAM and can't be used as real devboxes, mostly just good for run agent script Sandboxes can't run complex monorepos like Neon VMs can😜 freestyle.sh/products/vms

@ivanburazin Will be added to my future list of best tools, I’m already using it in @reproly (The AI support engineer I’m building)
Sidi jeddou@sidi_jeddou_dev

If you're a developer, trust me, this is for you. These are and gonna be the best tech in 2026: -@opencode: A coding agent that works in Terminal, IDE, and it's so good. -@tan_stack: The best ecosystem for frontend, if you hate or want an alternative to Nextjs, they have TansStack Start you can deploy it on @Netlify, @Cloudflare not a locked framework :) -@convex: One of the best and modern backend framework out there, and it's also self-hosted -@shadcn: The godfather of UI libraries, I think he doesn't need an explanation. -@autumnpricing: The fastest way ever to setup Stripe in your projects and start getting payments -@better_auth: My favorite auth library now. -@clerk or @WorkOS if you're lazy and want a fast auth with so cool features out of the box that you don't want to manage yourself -@polar_sh: Since Stripe acquired lemonsqueezy and killed it, this is the best alternative in the market now -@tembo: Your way to go for code review, the team is cooking, I've talked to @connorpaton about something and found out they are ahead -@Sentry: This is a must for every project, to catch bugs and fix them, maybe be smart and use it with @tembo -@appwrite: Another cool backend framework and ecosystem to build your full-stack apps -@firecrawl: The best and fastest scrapper out there, and I really bet o it. -@ExaAILabs: Best search API for agents and modern apps -@expo: My way to go for mobile apps, I used it and from day one, I really understood 90% of the framework, Btw, I have an app on Google play and Apple store. -@mintlify: I will never build a docs and there's mintlify. Please share yours in the comments if I missed it, I would like to learn new stuff 👇

CodeSandbox, a decade ago, was actually one of the first companies to use microVMs, snapshotting, and forking for developer environments. But the market wasn't ready. Human developers weren't going to abandon localhost, no matter how good the cloud IDE was. Now, agents don't have that attachment. They never had localhost to begin with. The same technology that was a decade too early for humans turns out to be exactly on time for agents.

@benswerd I am trying 😁 Are you using rust internally? Feel like it's really hard to use an of the shelf sandbox provider because to run things nearly you want really good CPU performance and very big fast disks.(Incremental complication) But turns out vms are a lot harder than containers
