Swapping Agent Sandbox Providers With Effect Layers: One-Line Switch Between e2b and Daytona
samgoodwin89 · x · 2026-11-15
A practical pattern for avoiding vendor lock-in across agent sandbox providers: since e2b, Daytona and similar services all follow the same template-snapshot-fork flow, wrap them behind your own Context.Service interface with one Effect Layer per provider. The shared code shows a Runner interface with run(cmd), E2BRunner and DaytonaRunner implementations, and a one-line change of Effect.provide(E2BRunner) → Effect.provide(DaytonaRunner) to switch providers with zero business-code changes.
