we've come a long way integrating sandboxes into @harborframework (15 providers now) with Modal, Daytona, and E2B being the three most popular ones.
docs aren't sexy, nevertheless @alexgshaw and i spent a lot of time rewriting these. worth a look. e.g. this env var section is the first time it's been explained clearly.
Sandboxes are no longer black boxes.
Harbor now streams the agent's trajectory (right) and files (left) as it runs.
