Devin vs Windsurf: Same Company, Two Very Different Jobs
Windsurf is not Devin’s rival — it is Devin now. Cognition rebranded Windsurf as Devin Desktop on June 2, 2026 (windsurf.com redirects to devin.ai/desktop) and retired the Cascade agent on July 1. What you are actually choosing between is a cloud agent billed by usage (Devin, from $20/mo plus ACU) and an IDE with a free tier that also manages your cloud agents. Most developers end up wanting both, and the pricing models are so different that comparing headline numbers is meaningless.
Buy this when you have a queue of well-scoped tasks you want off your plate and reviewed as pull requests.
Buy this for daily work in an editor — and because it is the console that manages cloud Devin too.
First, the Part Search Results Get Wrong
Almost every “Devin vs Windsurf” result is comparing a product with its own former self. Windsurf was renamed Devin Desktop on June 2, 2026, delivered to users as an ordinary over-the-air update, and Cascade — the agent most Windsurf tutorials are built around — was retired on July 1, 2026 in favour of Devin Local. So this is not a two-vendor bake-off. It is one company selling an autonomous cloud engineer billed by the ACU and an IDE sold per seat, with a shared brand and a shared control surface. Decide which job you are buying, not which logo you prefer.
Key Differences
| Devin (cloud) | Devin Desktop | |
|---|---|---|
| What it is | Autonomous coding agent in a cloud sandbox | AI-native IDE (VS Code based), formerly Windsurf |
| Who does the work | Devin plans, codes, tests and opens the PR | You work in the editor; local and cloud agents assist |
| Where it runs | Cognition's cloud — cloud-only, no local mode | A local desktop app you install |
| Billing model | Seat + metered ACU (Agent Compute Unit) | Seat plans with daily/weekly usage quotas |
| Entry price | $20/mo Core, plus ACU usage | Free ($0) |
| Free tier | None | Yes — light agent quota + unlimited Tab autocomplete |
| Team pricing | $500/mo Team, includes 250 ACUs | From $80/mo base + $40/seat |
| Heavy-use ceiling | Top up ACUs at ~$2.00-2.25 each | Max plan at $200/mo |
| Model story | Cognition's own SWE model line | Multi-model, plus any ACP-compatible agent |
| Best at | Whole scoped tasks you want delegated | Daily flow, local edits, agent management |
| Main weakness | Vague specs burn ACUs; small edits are slow | You still drive — it will not finish a feature for you |
| Signature agent | Devin itself | Devin Local (Cascade was retired on July 1, 2026) |
What Each One Really Costs
| Scenario | Devin (cloud) | Devin Desktop | What to watch |
|---|---|---|---|
| Trying it out | $20/mo minimum — no free plan | Free plan, unlimited Tab autocomplete | The biggest difference for individuals: one side costs money to evaluate, the other does not. |
| One small, well-scoped task | Under 1 ACU — roughly $2 | Comes out of your quota | Cloud Devin is genuinely cheap per task. The risk is tasks that do not stay small. |
| A full day of delegating | ~5-10 ACUs ≈ $10-22 at Core top-up rates | Covered until your quota resets; Max $200/mo for heavy use | Derived from 1 ACU ≈ 15 min of active work × ~$2.00-2.25 per ACU. Estimates, not invoices. |
| Individual, heavy daily use | Can exceed $200-300/mo | $20/mo Pro, or $200/mo Max | Desktop pricing is predictable. Cloud Devin scales with how much you hand over. |
| A 5-person team | $20 Core seats + ACUs, or $500/mo Team (250 ACUs) | Free seats; Teams ≈ $80/mo base + $40/seat | The Team bundle is the only way cloud ACUs get cheaper (~$2.00 vs ~$2.25). |
| The hidden line item | Vague specs: Devin iterates the wrong way and keeps billing | Frontier models burn quota faster, and quota resets rather than rolls over | Both punish weak scoping — one in dollars, the other in waiting. |
* Devin ACU estimates use Cognition's own definition (1 ACU ≈ 15 minutes of active autonomous work) plus published rates ($2.25/ACU Core top-up; ~$2.00/ACU effective on the Team plan). Day-level and team-level rows are derived estimates, not invoices. Devin Desktop figures are published list prices; your region and seat count determine the actual quote. Verified September 12, 2026.
Which One Should You Pick?
Pick Devin (cloud) if…
- You want whole tasks off your plate: a written spec in, a reviewed pull request out — not a faster editor.
- The work is modular and batchable: test coverage, dependency upgrades, framework migrations, small bug-fix queues.
- You are willing to write tight, unambiguous specs. Scope discipline is the single biggest lever on your ACU bill.
- Your team runs enough volume to justify Team pricing — 250 bundled ACUs work out cheaper per unit than Core top-ups.
- You already have an editor you like. Cloud Devin does not ask you to switch tools.
Devin Desktop if…
- You want to try before paying: the free plan includes unlimited Tab autocomplete plus a light agent quota.
- Most of your work starts locally and keeps you in the loop — refactors, debugging, reviewing generated code.
- You want to manage several agents, local and cloud, from one board instead of juggling browser tabs.
- Predictable billing matters more than theoretical autonomy: $20 Pro or $200 Max instead of a meter.
- You want model choice — including agents from other vendors, via the Agent Client Protocol.
Where Each One Falls Short
Devin (cloud)
- No free tier: evaluating Devin costs $20, and ACU spend starts immediately.
- Small changes are slow. Cloud warm-up and sandbox start-up make quick edits frustrating.
- No plugin ecosystem and no mid-task intervention — you review after Devin has finished.
- Cloud-only: your code and context live in Cognition's environment, with no air-gapped option.
- A large or vaguely specified task can consume 5-10+ ACUs and still not produce a mergeable pull request.
Devin Desktop
- You still drive. It is a faster editor, not a delegate — it will not finish a feature while you are away.
- Cascade is gone (EOL July 1, 2026): the agent you may have learned has been replaced, and old workflows need re-checking.
- Quotas reset instead of rolling over, and frontier models consume them faster than most people expect.
- The rebrand broke the documentation trail — search results still mix Windsurf-era advice with Devin-era behaviour.
- It cannot match cloud Devin's autonomous depth on large end-to-end tasks; you are still the one closing the loop.
The Honest Answer: Most Teams Want Both
The “vs” framing hides the actual product design. Cognition positions Devin Desktop as the control plane for agents — local ones and cloud ones — which means cloud Devin is not the alternative you pick instead of Desktop; it is one of the agents Desktop manages. Buy Desktop seats for your developers, then add cloud Devin only when you can point at a specific queue of well-scoped tasks worth delegating. If you truly must pick one: start with Desktop, because it has a free tier and no metered billing.
- Typical setup: Desktop seats for daily work (free to start, $20 Pro), cloud Devin only for the delegation backlog.
- Spaces shares context between agents, so a Desktop session and a cloud task can work the same problem.
- ACP support means agents from other vendors can run alongside Devin inside the same interface — you are not locked to Cognition.
- Budget check: one heavily used cloud Devin seat can cost more than two Max seats on Desktop.
Already on Windsurf? What Actually Changed
Nothing breaks (officially)
Cognition states Devin Desktop remains fully backwards-compatible with Windsurf: editor, extensions, keybindings, LSP, terminal and your existing workflow all carry over. It arrived as a normal over-the-air update, not a reinstall.
Your agent changed
Cascade reached end-of-life on July 1, 2026 and was replaced by Devin Local. Re-verify any Cascade-specific rules, custom prompts or saved flows instead of assuming identical behaviour.
The default surface moved
The Agent Command Center is now the default interface — a board for local and cloud agents, PRs and shared context. Expect a re-learning period where your old panel used to be.
Links and documentation moved
windsurf.com redirects to devin.ai/desktop. Tutorials, comparison posts and pricing pages from the Windsurf era may describe plans or a credit system that no longer exist.
Re-check your plan and billing
Credit-based billing was replaced by daily/weekly usage quotas in March 2026, and plans were restructured again in June. Confirm what your renewal actually includes before assuming the old price still applies.
FAQ
Is Windsurf the same as Devin?
Windsurf was rebranded as Devin Desktop on June 2, 2026 — the same editor, now under Cognition's Devin brand. But "Devin" on its own usually means the autonomous cloud agent at devin.ai, which is a different product with a completely different price list. Devin Desktop is the IDE; cloud Devin is the agent you delegate to.
Did Windsurf shut down?
No. The editor still exists — it was renamed Devin Desktop and delivered as an over-the-air update. Cognition states it is fully backwards-compatible with Windsurf. What did shut down is the Cascade agent, which reached end-of-life on July 1, 2026 and was replaced by Devin Local.
What happened to Cascade?
Cascade, Windsurf's signature agent, reached end-of-life on July 1, 2026 and was replaced by Devin Local. If you built custom rules, saved prompts or workflows around Cascade, re-verify them rather than assuming identical behaviour.
Which is cheaper, Devin or Devin Desktop?
For individuals, Devin Desktop by a wide margin: it has a free plan, and Pro is $20/month with usage quotas. Cloud Devin starts at $20/month too, but charges ACU usage on top — about $2.25 per ACU on Core and around $2.00 on Team — so heavy delegation can push a solo developer past $200-300/month. Desktop wins on predictability; cloud Devin wins on work you never have to do yourself.
Does Devin Desktop have a free plan?
Yes — a free tier with a light agent quota plus unlimited Tab autocomplete. Cloud Devin does not: it starts at $20/month Core with metered ACU usage on top, and complex tasks consume 5-10+ ACUs.
Can I use cloud Devin without Devin Desktop?
Yes. Cloud Devin is a browser-based product: you connect a repository, describe a task, and review the pull request it opens. Devin Desktop is optional — it simply gives you one interface for managing both cloud and local agents.
Can I use Devin Desktop without cloud Devin?
Yes, and that is the common case. Devin Desktop is a full IDE with its own local agent (Devin Local), plus a free plan. Plenty of individual developers use it and never buy cloud Devin at all.
Is Devin the same as Devin Desktop?
No — this is the most common mix-up. Devin is the autonomous cloud engineer billed by ACU. Devin Desktop is the IDE formerly called Windsurf, billed per seat with usage quotas. They share a brand, a company and a control interface, but not a price list.
What is one ACU worth?
Roughly 15 minutes of Devin's active autonomous work — planning, coding, running tests. Time spent idle waiting for your reply is not billed. A small, well-scoped task usually costs under 1 ACU (about $2); a medium feature runs $5-15; a large or vaguely specified task can burn 5-10+ ACUs and still fail to produce a mergeable pull request.
Will my Windsurf subscription and extensions keep working?
Officially yes — Devin Desktop is backwards-compatible with Windsurf, and existing plans, settings and extensions carried over at the rebrand. But the billing model changed: credit-based billing was replaced by daily/weekly usage quotas in March 2026, and plans were restructured again in June. Confirm your renewal terms rather than assuming your old price.
