Line-by-line comparison
Strengths and weaknesses
Devin
- True end-to-end autonomy: give it a Linear ticket or Slack message and it plans, codes, runs tests and opens a PR from its own cloud VM, in parallel sessions
- Entry price collapsed from $500/mo at launch to $20/mo (Pro), making the strongest autonomous agent accessible to individuals
- Devin Desktop (the former Windsurf IDE, rebranded 2026-06-02) bundles a local agent with subagents plus Tab completions, so one subscription covers IDE work and cloud tasks
- SWE-1.5 in-house model serves fast local edits at roughly 950 tokens/second, reportedly far faster than routing everything through frontier APIs
- Pro plan includes access to OpenAI, Claude and Gemini frontier models, not just Cognition's own
- Teams report reliable wins on well-scoped work: internal dashboards, migration scripts and test suites that save hours of boilerplate per task
- Usage costs are the trap: quotas refresh daily/weekly and complex tasks burn through them fast; under the legacy ACU system ($2.25 per ~15 min of work) a medium task ran $22-56, and heavy users report real spend drifting toward $300-500/mo
- The 2024 launch demos were partly debunked (Upwork tasks simpler than portrayed), and it still overreaches: on vague or novel problems it can iterate expensively toward a wrong solution
- No long-term memory across sessions; its grasp of your codebase is bounded by what fits in one session's context
- Pricing structure has churned repeatedly (Core, Team, ACUs, now Free/Pro/Max/Teams), making cost forecasting genuinely hard
- Closed source and cloud-first: your code runs in Cognition's VMs, a non-starter for some compliance regimes
Cline
- Genuinely free and Apache 2.0 licensed: 58.2K GitHub stars, 5.8K forks, 297 contributors as of Feb 2026, forkable if the company ever disappears
- Total model freedom (BYOK): Anthropic, OpenAI, Google, AWS Bedrock, GCP Vertex, Groq, DeepSeek, or free local models via Ollama, with inference sold at cost when you use Cline credits
- Near-zero switching cost: uninstall the extension and VS Code is untouched, .clinerules are plain text files in your repo
- Full agentic loop with approval gates: multi-step execution, terminal automation, headless browser testing of UI changes, and MCP marketplace for external tools
- Real-time cost transparency with per-operation token counts, unlike opaque credit systems of hosted builders
- Power-user favorite combo: runs as an extension inside Cursor, adding model freedom and MCP on top of Cursor's completions
- No inline tab autocomplete: it is a task-based agent, not a line-completion tool, so most users pair it with Copilot or Cursor
- BYOK costs are on you and can run away: heavy users report $10-20/day on Opus-tier models, roughly $30-80/month for typical professional use
- Slower than integrated rivals on comparable tasks (one 2026 benchmark measured 90s vs 45s for Cursor) and no background agents or codebase-wide predictive indexing
- Setup requires developer literacy: API keys, model selection and cost monitoring are your job, nothing is one-click
- JetBrains support and fine-grained permissioning are gated behind the Enterprise plan (custom pricing)
Cast your verdict
One recommendation per tool per gladiator. It reshapes the crowd score everyone sees.
The arena’s verdict on Devin
Buy Devin if you have a backlog of well-scoped, verifiable tasks and want them done in the background while you work: at $20/mo entry it is the most complete autonomous engineer you can hire, and the Windsurf-derived Devin Desktop makes the package genuinely daily-drivable. Budget realistically though: the sticker price is not the real price, and heavy delegation can push spend toward $300-500/mo. Avoid it if you mainly want interactive pair programming, where Claude Code or Cursor give more control per dollar, or if code leaving your infrastructure is a dealbreaker. Skip the Free tier for anything serious; its quota is demo-sized.
The arena’s verdict on Cline
Cline is the default recommendation for developers who want a serious agentic coder without vendor lock-in: the software costs nothing, every token is billed at provider cost, and you can swap models per task, down to free local Ollama for grunt work. Expect to pay $30-80/month in inference for typical professional use with frontier models, which often beats a $200 IDE subscription while staying fully under your control. Skip it if you want tab autocomplete, background agents or a zero-setup experience: Cursor is faster and more polished for that, and many power users simply run Cline inside Cursor to get both. Non-developers should start with Bolt.new or v0 instead, as Cline assumes you can read the code it writes.
What the crowd says
On Devin
“Watch your usage dashboard like a hawk. One gnarly refactor ate my whole weekly quota and it STILL got the edge cases wrong. Great for boilerplate, do not trust it with anything novel.”
“The Windsurf merge actually made this good. Local agent for quick edits, cloud Devin for the long tasks, one bill. Did not expect Cognition to pull that off.”
“Fed it our Jira backlog of small bugs and it cleared 9 of 12 with mergeable PRs in a weekend. The 3 failures were tickets a junior would have botched too. Worth the $20 easily.”
On Cline
“No tab autocomplete hurts at first, but for multi-file refactors it's the most trustworthy agent I've used. Apache 2.0 means no rug pull.”
“The MCP marketplace plus Plan/Act gates is the right model for agentic coding. I run it inside Cursor and get the best of both.”
“Switched from a $200/mo IDE plan to Cline with my own Anthropic key. Spending about $50/mo in tokens and I can see exactly where every cent goes.”
