Devin vs Jules: the short answer
Devin and Jules both let developers delegate tasks to cloud agents. Devin is Cognition's product with Free, Pro, Max and Teams plans and quotas; Jules is Google's asynchronous agent bundled with Google AI plans and limited by daily and concurrent task counts.
Devin also includes an editor and review tools, while Jules is a focused background agent that proposes pull requests. Both are classified here as autonomous agents whose output still needs review. We compare what documentation supports and mark everything else Unknown. We declare no overall winner, because the better choice depends on workflow, model preferences, oversight needs and budget.

Devin
Strengths and limitations from the profile
- Offers a free plan that includes Devin Review and DeepWiki, so teams can try parts of the product before paying.
- A single allowance covers cloud sessions, the CLI and Devin Desktop.
- Documents both self-serve tiers and ACU-billed Enterprise contracts.
- Clear individual ladder: Free, Pro $20 and Max $200.
- Pro and Max are single-user plans, so shared use requires the Teams plan.
- The product and plan names have changed repeatedly in 2025 and 2026, so older guides and prices are unreliable.
- Human-approval and permission controls were not reviewed in the sources used here.
- Usage quotas are not published as fixed numbers, so monthly spend can be hard to forecast.
Jules

- Works asynchronously in the cloud, so developers can keep working while tasks run.
- Includes a free introductory plan with 15 tasks a day.
- Task-based limits make usage easier to forecast than token billing.
- Bundled with Google AI Pro and Ultra, with 5x and 20x higher limits.
- Task caps and concurrency limits apply on every plan.
- Reports on the price of Google AI Ultra conflict.
- Uses Gemini models only.
- Approval and permission controls were not reviewed in the sources used here.
