Bolt.new
- +Full dev environment runs in the browser via WebContainers, with the AI controlling filesystem, terminal, and server
- +Generates true full-stack apps (not just UI) and can deploy via Bolt Cloud
- +No local setup; fast for prototyping and iterating by chatting
- -Token-based usage cost can rise quickly on complex or long-running builds
- -Output needs human review and iteration; it is not a hands-off autonomous engineer
E2B
- +Fast, secure isolated execution purpose-built for AI agents
- +Open-source SDK and self-hostable runtime, with a managed cloud option
- +Model-agnostic: runs whatever code any model produces
- -Infrastructure only; you bring the agent logic and orchestration
- -Hosted usage costs scale with sandbox runtime
