thanks! we're actually a layer above sandbox companies. the closest comparison is probably Conductor Cloud.
we run our own raw Firecracker microVMs instead of building on a sandbox provider, which gives us much more control over the runtime + significantly better usage/$.
that lets us do things like:
-writer/reviewer agents that actually run the code and iterate until review passes
-proof with screenshots, demo videos + live preview links
-break large features into a DAG of stacked PRs and parallelize the work
-live dev previews for any PR, even ones not created by Aether
basically, sandboxes give agents a computer, what Aether is building is comparable to an engineer working on that computer
