| Multi-file edits | Yes | Yes |
| Git operations | Yes | Yes |
| Browser control | No | YesCloud sessions ship a first-party interactive Browser tool alongside the shell and IDE, with saved browser profiles for authenticated sites (https://docs.devin.ai/work-with-devin/browser-auth). |
| Sandboxed execution | No | YesCloud sessions run on a dedicated Devin machine built from environment blueprints and snapshots, and the Devin CLI adds OS-level isolation locally (https://docs.devin.ai/cli/sandbox). |
| Multi-agent orchestration | YesAWS describes specialised agents per domain (mainframe, .NET, VMware, discovery and planning) working across the phases of a transformation. | Yes |
| Headless / CI mode | No | Yes |
| Models | ||
| Backbone | Amazon Bedrock | Undisclosed (Cognition-managed models) |
| Bring your own model | No | NoA cross-provider model picker (`--model` / `/model` / config `agent.model`) selects between Anthropic, OpenAI, Google, Cognition and open-source models, but every one of them is served by Cognition: the CLI model reference documents no API key, base URL, gateway, Bedrock, Vertex or Azure deployment of your own, matching pricing.byok = false. |
| Local models | No | NoNo base URL, gateway or local endpoint setting exists in the Devin CLI config reference (https://docs.devin.ai/cli/reference/configuration/config-file). |

| Pricing model | usage | mixed |
| Starts at | n/a | $20/mo |
| Free tier | No | Yes |
| Bring your own key | No | NoUsage is billed in Cognition ACUs and no LLM provider key can be supplied; Devin Outposts (https://docs.devin.ai/cloud/outposts/overview) only moves session compute onto your own machines. |

Which one would each critic pick
| Critic | AWS Transform | Devin | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.0 | 6.3 | Devin — The most complete autonomous stack here, with a cloud VM, browser and pull requests; pay for it if you can hand off whole tickets, not if you want a pair. |
| El Crítico | 5.8 | 5.3 | AWS Transform — A migration fails quietly through changed behaviour, not a stack trace, and the service documentation describes no verification step that would catch it. |
| El Profesor | 6.0 | 5.0 | AWS Transform — Specialised agents are assigned per domain across discovery, wave planning, landing zones and network migration, and the models behind them are never named. |
| La Inversora | 8.0 | 6.8 | AWS Transform — Billed straight through the AWS account, and the pricing page did not render a readable rate card at listing, which is a strong position and a weak disclosure. |
| La Jefa | 6.8 | 5.8 | AWS Transform — Seats are the wrong unit here; this is a programme billed to an account we already hold, with identity and audit inherited from the cloud contract legal signed. |
| El Hacker | 3.5 | 2.5 | AWS Transform — Proprietary, cloud only, no bring-your-own-key, no local option, no tool protocol, and the entry point is a button in a web console. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
