Spec by spec
| Spec | Lovable | Replit Agent |
|---|---|---|
| Architecture | ||
| Category | Web app builder | Web app builder |
| Runs | cloud | cloud |
| Platforms | web | web |
| Context window | not documented | not documented |
| Protocols | ||
| MCP client | Yes | Yes |

| Capabilities | ||
| Runs terminal commands | No | Yes |
| Multi-file edits | Yes | Yes |
| Git operations | Yes | Yes |
| Browser control | YesBuild mode drives a real browser in a remote virtual environment, clicking buttons, filling forms, navigating pages, reading console logs and network requests and capturing screenshots. | Yes |
| Sandboxed execution | No | YesEvery app runs on Replit's managed cloud compute, with Reserved VM publishing inside a dedicated single-tenant GCP project fully isolated from other customers' apps (https://docs.replit.com/learn/projects-and-artifacts/replit-deployments); the isolation is real but it is Replit's to configure, not yours. |
| Multi-agent orchestration | Yes | Yes |
| Headless / CI mode | NoNo CLI or scripted run mode is documented; the Lovable API currently only builds from prefilled share links, so the hosted MCP server is the sole programmatic driver. | NoNo CLI, REST API or CI runner is documented; the hosted MCP server is the only programmatic way to drive Agent. |
| Models | ||
| Backbone | Claude | Claude, GPT, Gemini |
| Bring your own model | No | YesCore and Pro builders pick the primary model themselves (Anthropic, OpenAI or Kimi) in Agent Mode's Power and Max modes, but only from Replit's hosted list — no custom endpoint, gateway or key. |
| Local models | No | No |
| Cost | ||
| Pricing model | subscription | mixed |
| Starts at | $25/mo | $20/mo |
| Free tier | Yes | Yes |
| Bring your own key | NoNo documented way to supply your own model key or account — project Secrets hold API keys for the app you build, not for the models Lovable runs on. | No |

Which one would each critic pick
| Critic | Lovable | Replit Agent | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.3 | 6.3 | no preference |
| El Crítico | 5.5 | 5.5 | no preference |
| El Profesor | 5.8 | 5.8 | no preference |
| La Inversora | 7.5 | 7.5 | no preference |
| La Jefa | 5.8 | 5.3 | Lovable — Business at $50 buys SSO and role-based access, Enterprise adds SCIM and audit logs, and none of it changes the fact that engineers cannot open a terminal; approved with conditions for product teams. |
| El Hacker | 3.8 | 3.5 | Lovable — Closed, Claude only, no key of my own and no shell, but it exposes an MCP server at mcp.lovable.dev, which means my agent can use it as a tool while I keep the real work at home. |
