Launch HN: Agent37 (YC F26) – Low-cost agent sandboxes for running agents
Hey HN, I’m Vishnu from Agent37 (https://agent37.com). We build sandboxes for running AI agents at under 10% of the cost of most sandbox providers. Our customers spend an average of $0.37/month per sandbox.
You can view a video walkthrough of the product here: https://youtu.be/DK5ISR2tbNo
We started as one of those OpenClaw wrapper companies back in February (yup.. judge me). In time we added more and more harnesses.
One of the goals I had at the time was to offer a free plan to users, so as to gain more market share. But it was too cost prohibitive to do it right away. Especially since we were bootstrapped and servers were running on my savings.
Today we’re actually able to offer the free plan thanks to the optimizations we’ve made since. Over 90% of the new signups we have are just free plan users and they host their personal Hermes/Openclaw/Claude Code etc on our cloud. Our infrastructure cost for the free sandboxes averages around $0.05 to $0.10 per user per month.
Here are some techniques that have worked for lowering cost:
* When you look at agent harnesses, they have certain patterns in the way they consume CPU and RAM. They need CPU in bursts when they’re initializing or performing certain tasks, but beyond that, they’re often not peaking. They need more RAM for things like browser and computer-use tasks. Once the task is done, usage often comes back down. This is a key insight in lowering cost, so by efficiently managing the CPU/RAM utilization we could lower the cost.
* Secondly, you have to skip the hyperscalers when renting the Hosts. I worked at Amazon before and they have 80-90% margins on VMs. So it was an obvious choice once I looked at the prices to go one layer down to vendors like Hetzner and OVH. This alone was probably one of the biggest cost levers in reducing the cost.
* Thirdly, you also want to pick a technology stack that lets you efficiently cache and share resources across the host. We use gVisor for better utilization and fast boot times. It lets us use available host memory across sandboxes without reserving a full VM’s memory for each one. There are tradeoffs: our gVisor sandboxes don’t support workloads like Docker-in-Docker or Android emulators.
* And finally the size and shape of the hosts you buy also makes a big difference. RAM is typically the bottleneck when it comes to cost and not the CPU. This is specifically true for agent harness workloads, so when buying servers, we optimize for packing more RAM into a given host.
We also host full VM sandboxes for workloads that need them, including running Docker at a slightly higher price, but they are still pretty low cost given the rest of the techniques.
Overall, my learning has been that just by focusing on a niche of sandbox usecases, and optimizing for it you can give a much better cost/performance tradeoff.
I was previously a Senior Software Engineer at Amazon and an Engineering Manager at Quantcast. I built Amazon's internal AI chatbot, Diya, and their internal coding harness, Ziya.
If you’re someone who’s looking to run agents on sandbox and are exploring a sandbox vendor, come check us out. We’re particularly looking for developers building messaging agents to try their workloads and challenge the limits and economics of our platform.
Thanks!

Googlebook OS review: A post-smartphone PC, if Google can keep it
All attempts to bring the lessons and benefits of the touch era to PCs have failed, from Windows 8 to the era after the iPad when the Mac gained fullscreen apps. From an experience perspective, the iPad came closest because it was built on iOS, but it still failed due to the locked-down limitations at its core.
After using Googlebook OS for over a week, I think Google has the beginnings of a desktop OS for the Android smartphone generation, but the inherent strategy reset makes for a rough first take.

Fire destroys Marché des Enfants Rouges, ‘coolest market in Paris’
submitted by Powderhorn to news
9 points | 0 comments
https://www.theguardian.com/world/2026/oct/12/fire-destroys-marche-des-enfants-rouges-coolest-market-in-parisFire has ravaged Paris’s oldest surviving covered food market, a popular street food venue dating back to the 17th century in the Marais district of the French capital that drew thousands of locals and tourists daily.
Ariel Weil, the central Paris mayor, said the Marché des Enfants Rouges had been “totally destroyed” in the blaze, which broke out soon after 3am. “The worst was avoided: the fire did not spread to the surrounding buildings,” he said. “But there is a lot of emotion. A lot of sadness.”
The market was established in 1615 during the reign of Louis XIII and took its name from a nearby orphanage, the Hospice des Enfants Rouges – founded in 1536 by King Francis I and his sister Marguerite de Navarre – whose child residents were habitually dressed in red.
The structure was listed as a historic monument in 1982 but narrowly escaped demolition shortly afterwards when Paris city hall, led by the then mayor, Jacques Chirac, approved radical redevelopment plans that would have replaced it with an underground car park, a council daycare facility and community centre.
