Show HN: What a VM for your AI agent costs across 13 sandbox providers

https://vm-price-board.sf.tools/

I was annoyed by tracking all these new sandbox prices manually, and seeing a new one pop up on X every week.So I built a page where you describe the machine, and it shows what provider can provide it for the cheapest, free tiers included.Am I missing any providers? I can add more!page: https://vm-price-board.sf.tools, source: https://github.com/sf-tools/vm-price-board

> Odd choice for a vibecoded project.

I'm using coding agents to accelerate implementation, not to replace understanding or review. The architecture, technical decisions, testing, and final responsibility are still mine, so I don't think "vibecoded" is an accurate description here.

this is very out of date, from February. please just check the repo or even run the tests
Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Sunday July 12, 2026 @12:36PM (#48882412)
no sandbox on windows... yet!
Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Sunday July 12, 2026 @12:36PM (#48882406)
not anymore!

> How is it so much smaller than V8 while also apparently including a package manager, a web server, a TypeScript compiler and a hypervisor?

Much less complex tiers of jit, no unicode ICU, and no startup js snapshot

Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @11:05PM (#48877907)
would be cool to see!
Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @07:35PM (#48876866)
on linux its kvm, on darwin its hypervisor.framework, the memory is not upfront, by default 256mb is lazy allocated, and ~35mb are used by both ant + the vm. the kernel is https://nanos.org with patches to get ant+networking running smoothly
Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @07:19PM (#48876771)
its pretty fast tbh, though third-party benches would be great to have!
Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @07:03PM (#48876679)
this is coming soon!

I dont know a single soul who uses the Anthropic `ant` cli....
Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @05:14PM (#48875941)
yes! I will be making a roadmap like a comment here suggested, should help
Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @05:11PM (#48875920)
this was flagging code from all the way back in dec of 2025, back when this project was just some idea and not what it is today.

around feb thats when basically deleted the existing codebase and designed a much more reliable system from the ground up.

I knew the existing code was basically pure slop, and it was not the biggest issue then, now nothing goes past me unreviewed and untested

> To the author: I absolutely love what you're doing overall. Keep going! Just be careful, folks.

Thank you!

> interesting, is there any reason behind DNS/(ISP?) providers blocking .land domains?

tbh have not seen any reason behind it, just saw my ants.land get blocked a office firewall once while demoing

Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @05:05PM (#48875878)
many, the engine has basically gone through a full rewrite since feb, that was still mostly interpt and missing many jit ops.

nightly will include benchmarks soon as well

Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @04:52PM (#48875758)
thats very weird, its hosted on cloudflare workers atm. might be blocked by your isp? ive seen that happen to .land
Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @04:51PM (#48875736)
unknown, have not tried. but let me know if it does work

LATEST RELEASE REQUIRES A STATIC RELEASE HOTFIX!!

https://github.com/theMackabu/ant/actions/runs/29167621329.

im very sorry everyone who tried to install and got a libcares error :(

:D
Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @04:38PM (#48875622)
its ~8mb including the entire runtime and node-compat work. pretty simple to embed anywhere as well
Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @04:38PM (#48875615)
good idea!
Re:Show HN: Ant – A JavaScript Runtime and Ecosystem on Saturday July 11, 2026 @04:36PM (#48875597)
just got the thing for you actually! literally just finished a stable version last night, https://www.npmjs.com/package/ant-desktop. WIP still, chromium only renderer backend but webview and other backends coming soon as well. no local ant install needed as libant is bundled, when CI finishes ill have windows/linux builds too

Show HN: Ant – A JavaScript Runtime and Ecosystem

https://antjs.org

Hello HN!I'm the author of Ant, a JavaScript ecosystem built around a runtime with its own JavaScript engine. Ant also includes a package manager, the ants.land package registry, a platform for deploying and hosting applications, and Ant Desktop for building native desktop apps with web technologies, similar to Electron.The goal is for these pieces to work as one coherent platform while...

Show HN: Ant – A from-scratch JavaScript runtime in 9 MB

https://github.com/themackabu/ant

Hey HN! I have been working on Ant for a while now, would love to share around now.What is Ant? It's my JavaScript runtime, built from scratch over many hours of work. Much effort has gone into keeping the binary size small, around 9MB at the moment (6.5 MB with -Os). On my M4 Pro, the hono coldstart bench (examples/npm/hono/bench-coldstart.js) lands around 5ms, about 2.4x faster than bun, and...
