Devin and Replit Agent both promise the same fantasy — describe the work, get working software — but they start from opposite ends. Devin is an autonomous software engineer that works in the cloud and hands you pull requests. Replit Agent is a browser-based builder that turns prompts into deployed full-stack apps.
The practical difference: Devin plugs into your existing repos, team, and workflow; Replit Agent wants to be your whole stack — editor, hosting, and database included. This page compares them on price, autonomy, and who actually gets value out of each, using current published pricing.
| Devin | Replit Agent | |
|---|---|---|
| Starting price (paid) | Pro $20/seat/mo | Core $20/mo (billed annually) |
| Free tier | Yes, limited daily/weekly quota | Yes, daily Agent credits |
| How you work with it | Async: assign tasks, review PRs | Conversational: prompt in the browser workspace |
| Where code runs | Cognition cloud (isolated containers) | Replit cloud workspaces |
| Model choice | Multi-model: OpenAI, Claude, Gemini, Cognition SWE models | Frontier models, billed via effort-based credits |
| Main output | Pull requests into your existing repos | Deployed full-stack apps |
| Hosting included | No — you deploy with your own infra | Yes — Replit Deployments, database, auth |
| Parallel work | Unlimited concurrency on team plans | 2 parallel agents (Core), 10 (Pro) |
| Cost predictability | Usage quotas + pay-as-you-go credits; heavy use gets expensive | Shared credit pool; agent loops can burn credits fast |
| Open source | No | No |

Try Replit Agent →Pick Devin if you already have a codebase, a team, and a review process — it slots into how professional software gets built, working asynchronously while you review PRs. The per-seat entry is cheap, but watch the usage meter: autonomous agents are hungry, and heavy use is billed on top. Pick Replit Agent if you want the shortest path from idea to a live URL — prototypes, MVPs, internal tools, side projects. The trade is control: your code lives in Replit's cloud, deployments draw from the same credit pool as the agent, and costs get unpredictable exactly when the agent gets stuck. Both are usage-metered, so the honest advice is the same for both: start small, scope tasks tightly, and check the official pricing page before you commit — both vendors repriced in 2026 and will do it again.
No. Devin edits code and opens pull requests in your repos; you deploy with your own infrastructure. Replit Agent includes deployments, databases, and hosting in the same credit pool.
Entry pricing is similar — Devin Pro starts at $20/seat/month, Replit Core at $20/month billed annually. Both are usage-metered on top of the base plan, so real cost depends on how much agent work you run. Scope tasks tightly with either.
Replit Agent is explicitly built for non-developers — it handles the full stack in the browser. Devin assumes a professional workflow: repos, branches, pull requests, code review. If you can't review a PR, Devin's output won't help you.
