Will give these a try. These are exciting times, it's never been a better time to build side projects :)
Just an idea…
Even if this was true, "everyone building X independently" is evidence that one company should definitely build X and sell it to everyone
It's really useful to just turn a computer on, use a disk, and then plop its url in the browser.
I currently do one computer per project. I don't even put them in git anymore. I have an MDM server running to manage my kids' phones, a "help me reply to all the people" computer that reads everything I'm supposed to read, a dumb game I play with my son, a family todo list no one uses but me, etc, etc.
Immediate computers have made side projects a lot more fun again. And the nice thing is, they cost nothing when I forget about them.
Everything I want to pay attention to gets a token, the server goes and looks for stuff in the api, and seeds local sqlites. If possible, it listens for webhooks to stay fresh.
Mostly the interface is Claude code. I have a web view that gives me some idea of volume, and then I just chat at Claude code to have it see what's going on. It does this by querying and cross referencing sqlite dbs.
I will have claude code send/post a response for me, but I still write them like a meatsack.
It's effectively: long lived HTTP server, sqlite, and then Claude skills for scripts that help it consistently do things based on my awful typing.
The short answer is no. And more so, I think that "Everyone I know in my milieu already built this for themselves, but the wider industry isn't talking about it" is actually an excellent idea generator for a new product.
Here's my list of code execution sandboxing agents launched in the last year alone: E2B, AIO Sandbox, Sandboxer, AgentSphere, Yolobox, Exe.dev, yolo-cage, SkillFS, ERA Jazzberry Computer, Vibekit, Daytona, Modal, Cognitora, YepCode, Run Compute, CLI Fence, Landrun, Sprites, pctx-sandbox, pctx Sandbox, Agent SDK, Lima-devbox, OpenServ, Browser Agent Playground, Flintlock Agent, Quickstart, Bouvet Sandbox, Arrakis, Cellmate (ceLLMate), AgentFence, Tasker, DenoSandbox, Capsule (WASM-based), Volant, Nono, NetFence
disclaimer: i work at E2B
the value we sell with our cloud is scale, while our Sandboxes are a commodity that we have proudly open-sourced
High scalability and VM isolation is what the Cloud (GCP/AWS, that E2B runs on) offers.
A quick search this popped up:

If we can spin up microVM so quickly, why bother with Docker or other containers at all?
Looks like the main innovation here is linking outbound traffic to a host with dynamic variables - could that be added to deno itself?
That website does exist. It may hurt your eyes.
It uses web workers on a web browser. So is this Deno Sandbox like that, but for server? I think Node has worker threads.
