It is a very necessary building block for many common features that can be steered in a more deterministic way, e.g. "code interpreter" feature for data analysis or file creation like commonly seen in chat web UIs.
But like I see multiple sandbox for agents products a week. Way too saturated of a market
With respect to the market, every single sandbox sucks. I'm not gonna shit talk competitors but there is not a good sandboxing platform out there yet — including me — compared to where we'll be in 6 months.
We've heard all the platforms have consistent uptime, feature completeness, networking and debugging issues. And in our own platform we're not 1/10ths of the way through solving the requests we've gotten.
Next generation of Agents needs computers, and those computers are gonna look really different than "sandboxes" do today.
