box - Simple computers for agent w/ full VMs
by•
Box offers the simplest, cheapest cloud computers for agents, thought for builders of agentic platforms & software factories.
Run 'box new' in your terminal, in 2s get a beefy ubuntu VM, with admin rights, a desktop, ssh access.
At $0.036/hr it is 10x less expensive than the likes of E2B, Daytona, Modal, so you can run more agents, or run them longer.
Run up to 1000 concurrent boxes fully self-served, or ask us for more, with same-day support from the founders.

Hello Product Hunt,
2 years ago, I worked at the European Space Agency, scaling their black holes & binary stars research efforts.
At that time, GPT 4o already helped us find many optimizations that made the code more scalable. But to test them, our agents needed a cluster of cloud compute, which we had to wait 2 months to get. AI may work fast but compute provisioning is slowing it down.
After leaving, I spent 10 months building cloud coding agents, which needed cloud computers too, so I tried many self-serve options for "computers for agents" and "AI sandboxes".
But there was no fit, they were optimized for bursty, short-lived scenarios on containers rather than full computers where anything just works...
... all while being super expensive, high multiples of what the same compute is worth in the average datacenter in Europe.
So 2 months ago, we built and launched box on X, our on-demand computers for agents, super cost-efficient and powerful.
Now our computers for agents have already run for 10 years in just 2 months, growing steadily every week.
Today, they already power many agentic platforms, software factories, cybersecurity audits platforms, with real customers in production.
Try box and let us know how it goes :) https://box.ascii.dev

@anic_dev congrats on the launch!

@marek_nalikowski thank you Marek!

@anic_dev Congrats on the launch. You guys built a great product. Happy user here!!

@pbteja1998 thanks Bhanu!

@thys_beesman we hit such low price because we designed the whole system for cost efficiency, using no dependencies and minimizing the operational costs. we have our own snapshotting system (beautiful tech built in-house), allowing you to easily stop/resume/fork your machine.

@thys_beesman Compute in European datacenters is just that cheap, its just hard to build around, we still make v good margins.
Built for Devs
Interesting. I just implemented this use case and landed on E2B. I'm running a platform that does agent evaluations of dev tools and the agents need sandbox environments to build in to validate the dev tool. How do you differ from E2B? I just built this feature a couple days ago so its quite new!

@tessak22 box.ascii.dev/compare explains well how we're positioned
tldr: if all you need is 4vCPU 8GB ram sandboxes we're 9-10x cheaper with comparable feature set

Hey guys!
im Kirill, the CTO of box.
Today, we're seeing 7 consecutive weeks of big usage growth, and compared to six months ago, our MRR is 130× higher. It's been an incredible ride, but we're still early, and we're shipping every single day.
I'd genuinely love your feedback: good or bad. If you're building coding agents, personal assistants, or any agentic product, you can find box super useful!

@luaroncrew @anic_dev LFG!

Good luck with the launch guys, amazing product!

@meta_nkt thank you Nikita!!
Very cool product. Having deployed at scale, most agent sandbox pain is re-provisioning, not compute. Curious how fast fork actually is under load. The persistent-VM + fork-from-snapshot combo is the part that actually changes how you build agent loops.

@aidan_codefox So many hard problems to solve in that space for so many different usecase.
We catter best to long running agent whose data is precious and never to be lost

Cool stuff. Where's best to DM you?

I'm a box user, been using it for (I think) a few weeks now. It's insanely fast, cheap (actually ridiculous), and good. Try them out! And congrats on the launch guys
box
@kartikskabadi Thank you so much Kartik! It's a pleasure to help you
too simple to use and spin up - been working on integrating this in my platform.
box
@arth_tyagi Hope it's going well! Lmk if I can help in any way :)

Congrats on the launch! Been using box and ascii for a few months now and couldn't be happier! Also support is really good, the founders are great. Love the CLI btw
