How to choose between Docker and Fly
Both Docker and Fly sit in Hosting & Infra, so running both usually means paying twice for the same job. The better question isn't which tool wins in the abstract — it's which one fits the stack you already run. Newtools keeps a live picture of your stack, spend, and decisions, then recommends the tool that fits and flags the spend you could cut.
