Agentic harness comparison
Claude Code vs Devin Desktop (formerly Windsurf)
Compared on where each one runs, which editors it supports, how autonomous it is, and how it bills — the four things that actually decide Claude Code vs Devin Desktop (formerly Windsurf). Rankings reflect fit and trade-offs, not a single universal winner; partner links, when present, do not replace that methodology.

Benchmark scores carry the month they were measured. Values we could not confirm are shown as “Not verified” rather than estimated.
Claude Code
Runs in the terminal rather than an IDE, so it sits alongside whatever editor the team already uses. Primary consumer access is via Claude Pro/Max/Team/Enterprise; Console/API is the alternate path.
Best for
- Multi-file refactors
- Migrations
- Delegated engineering tasks
Watch out
From 2026-08-14, new Pro/Max/Team sessions default to Auto (classifier-gated; classifier overhead free on those plans — Enterprise/API still opt-in). +50% weekly usage boost ends 2026-08-19 23:59 PT — don't size Pro/Max recommendations on temporary headroom. Included usage still shares allowance with Claude chat; an ANTHROPIC_API_KEY can bill API credits instead. Free Claude.ai does not include Claude Code. BAA + Claude Code requires ZDR, which blocks Covered Models (e.g. Fable 5) — plan HIPAA stacks accordingly.
Devin Desktop (formerly Windsurf)
Devin Desktop, formerly Windsurf, combines in-editor assistance with more autonomous edit flows — a separate product from Devin Cloud.
Best for
- Teams evaluating the current Devin Desktop surface
- Teams migrating from Windsurf
Watch out
Not Devin Cloud. Cascade reached EOL through July 2026 — Desktop’s current local agent is Devin Local. Quota can be shared with cloud sessions; confirm which surface you are buying.
Common questions
Claude Code vs Devin Desktop (formerly Windsurf)
Answered from the verified figures on this page rather than general guidance.
Do I have to change editor to use Claude Code or Devin Desktop (formerly Windsurf)?
Devin Desktop (formerly Windsurf) requires moving to its own environment, while Claude Code runs in the terminal alongside any editor. For a team that has not standardised on one editor, that difference usually outweighs any capability gap.
How are Claude Code and Devin Desktop (formerly Windsurf) priced?
Both are hybrid. The headline seat or plan price is not the heavy-agent bill — included credits, shared pools, and overages dominate once you loop agents hard. Estimate cost per successful task and set spend caps.
Is Claude Code or Devin Desktop (formerly Windsurf) better for large refactors?
Claude Code is the more autonomous of the two — agentic against hybrid — so it is the better fit for work you hand over whole. Devin Desktop (formerly Windsurf) is stronger for constant in-editor assistance. Those are different jobs, and many teams run one of each.
Should I run Claude Code and Devin Desktop (formerly Windsurf) together?
Often yes as a hybrid stack rather than forcing one winner. Keep the stronger in-editor assistant for daily tab/chat work and the more autonomous surface for longer delegated tasks, then standardise on a portable repo rules file so project memory survives switching. Pilot both on the same practice repository before consolidating seats.
Will my project rules transfer between Claude Code and Devin Desktop (formerly Windsurf)?
Usually not automatically. Cursor rules, CLAUDE.md, AGENTS.md, and extension-specific configs are different conventions. Keep one source of truth in the repository (commonly AGENTS.md) and copy or link into each tool’s native format so switching does not wipe months of project teaching.
Does Claude Code require a Max plan?
No. Claude Pro includes Claude Code with a shared usage pool alongside Claude chat. Max raises limits; Free Claude.ai chat does not include Claude Code. An ANTHROPIC_API_KEY can bill Console/API instead of the subscription pool.
Is Devin Desktop the same product as Devin Cloud?
No. Devin Desktop (formerly Windsurf) is a local IDE with Devin Local after Cascade EOL. Devin Cloud is the browser agent at app.devin.ai. Self-serve quotas can be shared, but they are different surfaces — do not buy one expecting the other.
Do coding agents replace code review?
No. Agents can draft patches faster, but they do not remove the need for human review of plans, tool calls, permissions, diffs, tests, and rollback paths. Treat autonomy as a reason for stronger review, not less — see the coding assistant rollout guide at /ai-harnesses/guides/coding-assistant-rollout-guide.
Should we harden MCP before rolling out a coding agent?
Yes for any agent that can install MCP servers or run tools. Maintain a short allowlist, review each server’s folder and network access before install, fail closed on unknown tools, and log tool calls. .cursorignore and similar rules do not block MCP or shell access once a command is approved.

Which one fits
Autonomy and editor constraints decide this far more reliably than a benchmark score.
If most of your week is small, frequent edits, an assistive workflow beats delegation and an agentic harness sits idle while billing. If you regularly hand over work spanning many files, the reverse is true.
Where one tool requires changing editor and the other does not, that difference usually outweighs any capability gap across a team — rollouts fail on adoption, not capability.
