Deno Sandbox

Deno just dropped Deno Sandbox, a safe “mini-computer in the cloud” where risky, user‑made or AI‑generated code can run without raiding your secrets or blasting the internet. The headline feature? Secrets never touch the app directly—only a harmless placeholder—and the real key appears only when the code calls approved websites. Think of it as putting mischievous AI code in a timeout, with a nanny cam on its internet access. The crowd went loud. Security‑minded folks cheered—emschwartz declared, “That seems clever,”—while skeptics asked if this cleverness breaks real‑world use. ttoinou fretted about rotating IPs getting them “banned from Anthropic,” and side‑eyed the 30‑minute lifetime cap like it’s training wheels that won’t come off. Meanwhile, pragmatists showed up with DIY energy: e12e asked for a self‑hosted version, and another deadpanned, “Firecrackervm with proxy?” as if the magic trick is just Linux sparks and a fancy lock. The community vibe is peak tech soap opera: some want this built into Deno itself, others just want it to run on their own hardware, and everyone’s replaying johnspurlock’s core fear—LLM‑made code wielding real API keys without a human in the loop. Memes branded it “code jail” and “baby monitor for APIs,” but the takeaway is clear: Sandbox might finally let platforms run wild user code without waking up to a crime scene. Watch the announcement and bring popcorn.
