Will Codespaces Replace Your Laptop?

The no-BS guide to cloud dev environments vs local machines in 2025.

Cloud dev vs local machines: speed, cost, security, and the day-to-day developer experience — plus practical playbooks to choose wisely.

If your laptop disappeared mid-sprint, could you still ship?

Where cloud dev absolutely wins

Instant, identical environments

Spin up a repo-defined devcontainer and you get the same toolchain, OS, and versions as your teammates — no more “install these 14 things.” New…
