- -Reviewer only: it comments and suggests but does not merge or push code itself
- -On large PRs AI review can be noisy and still needs human triage
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
