“It creates the task before it does the work, so it now files its own tickets, which is more process rigour than most teams manage.”
Spec by spec

| Runs terminal commands | Yes | No |
| Multi-file edits | Yes | Yes |
| Git operations | Yes | Yes |
| Browser control | 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). | No |
| Sandboxed execution | 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). | No |
| Multi-agent orchestration | Yes | No |
| Headless / CI mode | Yes | YesThe agent mode prepares a pull request and starts a deployment through the platform's own CI/CD. |
| Models | ||
| Backbone | Undisclosed (Cognition-managed models) | undisclosed |
| Bring your own model | 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. | No |
| Local models | NoNo base URL, gateway or local endpoint setting exists in the Devin CLI config reference (https://docs.devin.ai/cli/reference/configuration/config-file). | No |

| Free tier | Yes | No |
| Bring your own key | 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. | No |

Which one would each critic pick
| Critic | Devin | SourceCraft Code Assistant | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 5.3 | 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 | 5.3 | 4.8 | Devin — On-demand credits auto-refill, so an agent that loops spends money with nobody at the keyboard, and the meter is the risk on a tool built to run unattended. |
| El Profesor | 5.0 | 4.5 | Devin — Correct architecture, undisclosed models, and one self-reported figure from March 2024 on a quarter of the test set; the claims run two years ahead of the evidence. |
| La Inversora | 6.8 | 5.8 | Devin — Well funded, acquisitive, and repricing in public; the Windsurf purchase bought distribution, and the April 2026 plan change says the ACU math was not working. |
| La Jefa | 5.8 | 3.8 | Devin — Teams at $80 plus $40 per full seat with shared credits, and Enterprise by quote; the free flex seats are the part finance will like. |
| El Hacker | 2.5 | 2.8 | SourceCraft Code Assistant — Proprietary, browser-only, no key of mine, no protocol to speak to, no source to read, and the model is not even named. |
