Devin vs Cursor Background Agents: Which to Use?

Two approaches to async AI coding

Both Devin and Cursor Background Agents solve the same user problem: "I want to assign a coding task and come back to a finished pull request." The execution models are different enough that the right choice depends on what you're building and how much you're willing to spend.

Devin is a standalone platform. You dispatch tasks from Slack or a web UI. Devin works inside a full cloud VM with a browser, terminal, and code editor. It can navigate web UIs, read documentation sites, run end-to-end tests in a real browser, and interact with deployed applications. When it finishes, you get a PR with a full session recording. The Team plan starts at $500/month with ACU-based billing on top.

Cursor Background Agents are an extension of your IDE. You dispatch from within Cursor. The agent clones your repo into an Ubuntu VM, creates an agent/ branch, writes code, and opens a PR. It has access to your Cursor project context but no browser. Pricing is $4-5 per task on top of a $20/month Cursor Pro subscription.

The 10x price difference is the headline. But capability, workflow integration, and task complexity determine whether that difference is justified.

Feature Comparison

Devin: Full Autonomy at a Premium

Devin's cloud VM architecture is its differentiator. Each session gets an isolated environment with Chromium, a full Linux terminal, and a code editor. This means Devin can do things that no IDE-coupled agent can: open a staging URL, click through a UI flow, verify that a frontend change renders correctly, read API documentation from a web page, and interact with third-party services that require a browser.

The Slack dispatch model is the other differentiator. A product manager can type "Build the user settings page based on the Figma link in this ticket" into a Slack channel and Devin treats it as a work order. This opens AI engineering to non-developers in a way that Cursor Background Agents (which require the Cursor IDE) cannot.

Session recordings are valuable for teams that need auditability. Every action Devin takes is recorded: files opened, commands run, browser pages visited, decisions made. You can scrub through a 90-minute session and understand exactly what the agent did. This matters for regulated industries and for debugging when Devin's output isn't quite right.

The cost structure is the barrier. The $500/month Team plan includes an ACU allotment, but complex tasks burn through it quickly. Teams with heavy usage report monthly bills between $800 and $3,000. The unpredictability is the most common complaint: you can't reliably budget for Devin the way you can for a per-seat or per-task tool.

Cursor Background Agents: IDE-Native Simplicity

Cursor Background Agents take a simpler approach. You're already in Cursor, working on code. You describe a task, hit dispatch, and the agent starts working in the background. Your local Cursor session stays free for other work. When the agent finishes, you get a notification and can review the PR directly in your editor.

The agent/ branch convention is a clean workflow choice. Each background agent creates a branch prefixed with agent/, making it easy to identify AI-generated work in your git history. You review the diff, test locally, and merge or reject. The separation between human branches and agent branches keeps the codebase history readable.

Pricing is the strongest argument. At $4-5 per task, you can run 100 tasks per month for $400-500, which is comparable to Devin's base plan before ACU charges. For a team of five developers each running 5 background tasks per week, the monthly cost is around $500 total. The same volume on Devin would likely cost $1,500-2,000.

The limitations are real. No browser access means Cursor BG Agents can't test frontend changes, navigate web UIs, or read documentation that isn't in the repo. The IDE coupling means only Cursor users can dispatch tasks. And the Ubuntu VM environment, while functional, has less customization than Devin's full cloud VM.

Pricing Breakdown

The cost comparison is stark when you run the numbers on real workloads.

• 10 tasks/month: Cursor BG Agents: $60-70 ($20 sub + $40-50 tasks). Devin: $500+ (base plan, ACUs likely covered).
• 50 tasks/month: Cursor BG Agents: $220-270 ($20 sub + $200-250 tasks). Devin: $700-1,200 (base + ACU overages on complex tasks).
• 200 tasks/month: Cursor BG Agents: $820-1,020. Devin: $1,500-3,000+.

Devin becomes cost-competitive only when tasks are complex enough that its browser access and deeper autonomy reduce the number of iterations. If a task that takes Cursor BG Agents three attempts (3x $5 = $15) succeeds on Devin's first try, the per-task economics shift. But for routine work (bug fixes, test writing, small features), Cursor's predictable pricing wins every time.

Choose Devin if... / Choose Cursor BG Agents if...

Our take

For most development teams, Cursor Background Agents are the right starting point. The pricing is predictable. The workflow is native to where you already code. The agent/ branch pattern is clean and reviewable. You can run dozens of tasks per month without the bill becoming a line item that needs executive approval.

Devin makes sense in two specific scenarios. First: when tasks require browser access (frontend testing, web interaction, documentation lookup). Second: when non-developers need to dispatch engineering work from Slack. These are legitimate requirements, and no other tool matches Devin's capability in these areas.

A hybrid approach is practical: Cursor BG Agents for the routine backlog (80% of tasks), Devin for the complex work that needs full autonomy and browser access (20% of tasks). This keeps costs controlled while preserving access to Devin when you genuinely need it.

How do Cursor Background Agents actually work?

When you dispatch a background agent from Cursor, it clones your repository into a fresh Ubuntu VM, creates an agent/ branch, and starts working on your task. The agent has access to your project context from Cursor (file structure, recent edits, conversation history). When it finishes, it creates a pull request from the agent/ branch. You review the PR in Cursor or GitHub and merge if the work is acceptable.

Can Devin do everything a Cursor Background Agent can do?

Yes, and more. Devin has a full cloud VM with browser access, which Cursor BG Agents lack. Devin can navigate web UIs, interact with deployed applications, read documentation sites, and run browser-based tests. For tasks that require only code changes in a repository, both tools produce comparable results. The question is whether the additional capabilities justify Devin's higher price.

Which is cheaper for a team running 50 tasks per month?

Cursor Background Agents, by a wide margin. At $4-5 per task, 50 tasks costs $200-250 plus the $20/mo Cursor Pro subscription. Devin's Team plan starts at $500/mo with ACU charges on top. Even if Devin's ACU allotment covers 50 simple tasks, the base cost alone is double what Cursor charges for the same volume. The gap narrows only when tasks are complex enough that Devin's browser access and deeper autonomy reduce iteration cycles.

Can I use both Devin and Cursor Background Agents?

There's no technical barrier, but most teams pick one for cost reasons. A hybrid approach that works: use Cursor BG Agents for routine tasks (bug fixes, test writing, small features) where the $4-5 per-task cost is efficient, and reserve Devin for complex tasks that need browser access, multi-system interaction, or non-developer dispatch from Slack. This keeps costs down while preserving access to Devin's unique capabilities.
