E2B is fully open-source under Apache 2.0 and runs on GCP, AWS, Azure (preview) and locally on any Linux box that has /dev/kvm (Mac works via Colima, too).
my thoughts is that Firecracker might be not the best runtime for that, as it’s very minimal on devices it wants to support (famously no PCI out of the box)
we have recently switched from httpx for the same reason but instead went with the Rust-based pyqwest (runs on Hyper) it has also a drop-in httpx-compatible transport so migration was easy and also it supports http2 trailers
