Cursor vs Windsurf vs Devin vs Cline 2026: which AI coding agent wins?
Four products dominate the AI-coding-agent conversation in 2026, and they occupy genuinely different points on the autonomy spectrum. Cursor and Windsurf (renamed Devin Desktop by Cognition in 2026) are AI-enhanced IDE forks of VS Code where the human stays in the loop. Devin is an autonomous engineer that plans and executes multi-hour workstreams in its own sandbox without supervision; since March 2026 it ships on the same plan as Devin Desktop. Cline is the open-source middle path: agentic capabilities, full transparency, bring-your-own API key. This guide benchmarks all four on pricing, agent autonomy, IDE integration, and head-to-head workflow performance across 5 representative tasks. To match the right agent to your specific stack and budget, run our AI stack optimizer after reading.
- Pick by autonomy level: Cursor and Windsurf (now Devin Desktop) are human-in-the-loop IDE copilots at $20 per month each. Devin is an autonomous cloud agent that runs multi-hour tasks without supervision, and its quota comes with the same $20 Devin plan. Cline is open-source and free software with pass-through API costs.
- Windsurf vs Cursor cost: the old price gap is gone. Both Pro plans are $20 per month (September 2026); Devin's adds cloud agents, and its Max tier is $200.
- Devin's old $500 floor is gone: the cloud agent now runs on the $20 plan's quota (Max $200 for heavy use), so the question is task fit, not price: it suits long-horizon async workstreams, less so interactive coding where human-in-loop tools catch planning errors faster.
- Cline caveat: Cline has no subscription cost but active developer pass-through API spend can reach $50 to $200 per month depending on usage and chosen model.
ENTRY PAID PLAN
Cursor Pro and Devin Pro (Devin Desktop plus Devin Cloud agents) both start at $20 a month; Devin's old $500 team floor is gone.
5-ENGINEER TEAM, MONTHLY
Five engineers, scaled to the largest: Cursor Teams $200 (5 x $40), Devin Teams $280 ($80 + 5 x $40), Cline ~$1,250 at the top of our $750-$1,250 API-spend estimate.
WORKFLOWS TESTED
Five representative real-world workflows we ran all four agents against, timed across 3 runs per tool per task.

The four agents at a glance
Cursor (Anysphere)
VS Code fork with deep AI integration. Inline Tab autocomplete, Cmd-K inline edits, Composer agent mode, multi-file edits with diff review.
- Strength: Best-in-class tab autocomplete trained on Cursor's own usage data. Composer mode handles multi-file agentic edits with diff-review before apply.
- Caution: Closed-source; Pro has usage limits on Agent, so heavy users move up to Pro+, Ultra, or usage-based billing.
- Best fit: Solo developers and small teams who want a polished co-pilot with minimal setup. The default 2026 answer for most engineers.
Windsurf, now Devin Desktop (Cognition)
VS Code fork with the Cascade agent, renamed Devin Desktop by Cognition in 2026. It now doubles as the command center for Devin's cloud agents, and one plan covers both.
- Strength: Same $20 entry as Cursor, and the plan also includes Devin's cloud agents. Cascade handled longer planning chains than Cursor Composer in our May 2026 runs.
- Caution: Smaller ecosystem; some Cursor-only conventions (specific keyboard chord bindings) require re-learning. Two renames (Codeium, then Windsurf, now Devin Desktop) mean older docs and tutorials use stale names.
- Best fit: Developers who want an IDE copilot and an autonomous cloud agent on one $20 plan, plus the longer agent chains for refactor work.
Devin cloud agent (Cognition)
Autonomous AI software engineer. Plans, codes, and tests in a sandboxed cloud environment. You assign a task; Devin works for minutes to hours and returns a PR.
- Strength: Genuinely unattended for runnable tasks (dependency upgrades, simple feature delivery, multi-file refactors with clear specs). Slack integration lets non-engineers file tasks.
- Caution: Cloud runs draw on the plan's quota; heavy async use means Max ($200) or extra usage at API pricing. In our runs Devin still made planning errors on novel tasks and did best on well-scoped tasks with reference patterns in the repo.
- Best fit: Teams running parallel asynchronous workstreams (one operator coordinating 3-5 Devin sessions on bug triage, doc generation, dependency upgrades) where queued, well-scoped tasks can run while the team works on something else.
Cline (open source)
Open-source VS Code extension. Bring your own model (Claude, GPT, Gemini, local Ollama). Transparent agent loop: every read, write, and command is approved before execution.
- Strength: Total cost transparency (only API spend, no platform markup). Approval-required agent loop catches bad planning early. Works with any model including local Ollama for offline / privacy-sensitive work.
- Caution: Friction higher than Cursor: more configuration, no native tab-autocomplete (you'd pair Cline with a separate tab provider). API spend volatility; a runaway agent loop can rack up $20 in a single session.
- Best fit: Developers who want transparency and model flexibility, teams with strict data-residency requirements that need local-model fallback, and pros running specific fine-tuned models.
Pricing comparison: total cost of ownership
Headline pricing hides material differences. Cursor meters Agent usage inside its plans; Windsurf (Devin Desktop) and Devin now share one quota-based plan; Cline passes through everything. Prices re-checked September 27, 2026. Below is total monthly cost for three usage profiles: light (occasional use), heavy (8-hour-a-day pro), and team (5-engineer org).
| Tier | Cursor | Windsurf (Devin Desktop) | Devin (cloud agent) | Cline |
|---|---|---|---|---|
| Free tier | Hobby: limited Agent requests | Free: light quota | Pro and up | $0 ext + API spend |
| Pro (entry) | $20/mo | $20/mo | In the same $20 plan | ~$50-$80/mo (Claude API) |
| Heavy user (8hr/day) | Pro+ or Ultra | $200/mo Max | Same $200 Max plan | ~$150-$250/mo (BYOK) |
| 5-engineer team | $200/mo (5 x $40) | $280/mo ($80 + 5 x $40) | Same Teams plan | ~$750-$1,250/mo |
| API spend included? | Yes (usage limits) | Yes (quota; extra at API pricing) | Yes (same quota) | No (BYOK) |
| Local model support | No | No | No | Yes (Ollama) |

Workflow benchmarks: how each agent performs on real tasks
The interesting comparison is not feature-vs-feature but workflow-vs-workflow. We tested all four agents against five representative real-world workflows in May 2026, when Windsurf and Devin were still sold separately. The winner of each tells you which tool to reach for in that specific situation.
- Cursor: Composer mode, ~3 min, 12-file edit, diff-review accept
- Windsurf: Cascade, ~4 min, comparable quality, slightly longer chain
- Devin: ~10 min async, includes test run, slowest by clock
- Cline: ~6 min interactive, every step approved, most transparent
- Cursor: Manual, multi-prompt; 30-45 min hands-on
- Windsurf: Cascade chain helps; 25-35 min
- Devin: Async; 45-90 min unattended, PR ready
- Cline: Step-by-step; 40 min with full approval log
- Cursor: Chat + Composer; 10-15 min interactive
- Windsurf: Cascade; 12-18 min
- Devin: ~30 min async; sometimes misses repo conventions
- Cline: ~15 min with full investigation trace
- Cursor: Composer + Tab; 20-30 min flagship workflow
- Windsurf: Cascade flow; 25 min
- Devin: Async; 60 min including test passes
- Cline: Step-by-step; 45 min
- Cursor: @-mention codebase, fast index lookup
- Windsurf: Cascade context; comparable
- Devin: Slower; not the right tool for this
- Cline: Manual file references; slowest

Who wins by use case
Smart combination stacks (not one-tool-only)
The savviest 2026 setups combine two of these tools rather than picking one. Three combos worth considering:
The savviest 2026 setups combine two of these tools rather than picking one.Smart combination stacks
- Cursor + Devin: Cursor for interactive coding (8 hours/day), Devin for parallel async workstreams (dependency upgrades, doc generation, bug triage). Total $40/month solo on the two $20 Pro plans, more if either quota runs out. Right when you want Cursor's editor with Devin's async lanes.
- Devin Desktop + Cline: Devin Desktop (formerly Windsurf) as the daily IDE for fast Tab + Cascade, Cline as the "I need full transparency for this refactor" tool. Total ~$20 + $50-100 = $70-120/month. Most cost-efficient pro setup.
- Cline + Ollama local: Zero-egress stack for security-sensitive or regulated codebases. No data leaves the machine. Total $0/month (compute is local), but you pay in slower inference and the limit of what local models handle well.

Bottom line
In 2026, Cursor remains the default AI IDE for solo developers and small teams; Windsurf, now Devin Desktop, matches Cursor's $20 price and adds Devin's cloud agent to the same plan, so the old value-tier and $500-floor arguments no longer apply; Devin earns its quota when you have async workstreams to queue; Cline is the open-source path that wins on transparency, model flexibility, and total cost transparency. Most pros do not pick one; they pair an IDE-based copilot (Cursor or Devin Desktop) with either Devin's cloud agent for autonomous lanes or Cline for transparency-critical work.
