Key Takeaways
- Cursor has the most mature agent mode and multi-model flexibility (GPT, Claude, Gemini) inside a VS Code fork, but usage-based credits on top of the $20/month Pro base make monthly cost variable.
- Windsurf lost its price advantage in 2026. Its Pro tier rose from $15/month to $20/month in March 2026 β the same price as Cursor Pro. Its Cascade agent flow remains a genuine differentiator if you prefer its UX.
- GitHub Copilot moved to usage-based AI-credit billing on June 1, 2026. Pro is $10/month with $15 of included AI credits; Pro+ is $39/month; a new Max tier is $100/month. It is the default choice for teams already inside GitHub or Azure DevOps.
- Cline costs $0 itself β it is an open-source VS Code/JetBrains extension. You pay only for the LLM API tokens you use (OpenAI, Anthropic, OpenRouter, and others), or nothing at all if you point it at a local model via Ollama or LM Studio.
- None of the four vendors has a standard, checkable public affiliate program as of August 2026 β see the Affiliate Program Status section for what each vendor actually offers (referral credits, technology partnerships, or nothing).
- Pricing in this category has been unusually volatile in 2026. Cursor, Windsurf, and GitHub Copilot all shifted from flatter subscriptions toward usage/credit metering during the year β treat every dollar figure here as an August 2026 snapshot, not a guarantee.
π In One Sentence
Cursor wins on agentic maturity and model flexibility, GitHub Copilot wins for GitHub/Azure-standardized teams, Windsurf now matches Cursor on price, and Cline is the only genuinely free option once you supply your own API key or a local model.
π¬ In Plain Terms
All four tools can edit multiple files and run commands for you (agent mode). The real differences are price, which AI models you can use, and whether your code has to leave your machine.
Quick Facts
Verified directly against cursor.com/pricing, windsurf.com (redirects to devin.ai/pricing following the Cognition acquisition), github.com/features/copilot/plans, and cline.bot/pricing, cross-checked against independent pricing trackers. Subscription pricing for developer tools changes with plan revisions β confirm the current rate on the vendor site before subscribing.
- Cursor: free Hobby tier; Pro, Pro+, and Ultra all share a $20/month base with escalating included-usage multipliers (Pro+ β3x, Ultra β20x), plus usage-based billing once included usage runs out; Teams from $40/user/month.
- Windsurf: free tier with a light daily/weekly quota; Pro $20/month (raised from $15 in March 2026, matching Cursor); Max $200/month; Teams $40/user/month; Enterprise custom. The credit-pool system was replaced by daily/weekly quotas in March 2026.
- GitHub Copilot: Free tier (2,000 completions/month); Pro $10/month ($15 included AI credits); Pro+ $39/month ($70 included AI credits); Max $100/month ($200 included AI credits); Business $19/user/month (1,900 AI credits); Enterprise $39/user/month (3,900 AI credits). Moved to usage-based AI-credit billing on June 1, 2026.
- Cline: the extension itself is $0, open source, MIT-licensed. Real cost is whatever LLM API you connect (OpenAI, Anthropic, Google, OpenRouter, AWS Bedrock, GCP Vertex, Groq, Cerebras, DeepSeek, and more), or $0 if you point it at a local model via Ollama or LM Studio β both work with no API key required.
- Windsurf is now under Cognition (maker of Devin). windsurf.com redirects to devin.ai's pricing page following Cognition's acquisition of Windsurf's team, product, and brand; the Windsurf editor continues to ship under its own name with Devin integration layered in.
Editor's Choice: Cursor
Cursor is the pick for most professional developers who want the most mature agent mode and the widest model choice. Composer and Cloud Agents handle multi-file, multi-step changes with less hand-holding than the alternatives, and you can switch between GPT, Claude, and Gemini models inside the same editor. The trade-off is cost predictability: the $20/month Pro base covers a set amount of usage, and heavy agentic sessions can trigger additional usage-based billing. If GitHub-native workflow integration matters more than raw agent capability, choose GitHub Copilot instead; if $0 is a hard requirement, choose Cline with a local model.

Cursor vs Windsurf vs GitHub Copilot vs Cline
Pricing is an August 2026 snapshot verified against each vendor's own pricing page β Cursor, Windsurf, and GitHub Copilot all changed their pricing structure at least once in 2026, so confirm the current rate before subscribing. "Model Access" reflects what each tool lets you choose at the model-selection level, not just what powers autocomplete.
| Tool | Best For | Pricing (Aug 2026) | Model Access | Agent Mode | IDE |
|---|---|---|---|---|---|
| Cursor | Agentic multi-file edits / polish | Free Hobby / $20+/mo ProβUltra | GPT / Claude / Gemini (multi-model) | Composer + Cloud Agents | Cursor (VS Code fork) |
| Windsurf | Cascade agent flow, price now = Cursor | Free / $20/mo Pro / $200/mo Max | Claude, GPT, SWE-1.5 (multi-model) | Cascade | Windsurf editor (VS Code fork) |
| GitHub Copilot | GitHub/Azure-standardized teams | Free / $10 Pro / $39 Pro+ / $100 Max | GPT, Claude Opus (Pro+/Max), 3rd-party agents | Coding agent + agent sessions | VS Code, JetBrains, Visual Studio, CLI |
| Cline | Bring-your-own-key / local models | Extension free / pay-per-token API | Any OpenAI-compatible incl. local (Ollama) | Plan/Act agent, full transparency | VS Code, JetBrains |
Which Tool Should You Choose?
Choose based on your workflow and privacy needs, not on which tool markets itself as most "agentic." Each tool wins a different real-world scenario below.
- Heavy multi-file agentic work, willing to pay for polish β Cursor. Composer and Cloud Agents handle large refactors with the least manual steering of the four.
- You like Cascade's agent UX specifically β Windsurf. It no longer wins on price (both are $20/month), so pick it only if you've tried both and prefer its flow.
- Team standardized on GitHub Issues, PRs, and Azure DevOps β GitHub Copilot. The coding agent reads and writes directly against your existing GitHub workflow.
- Budget is $0 and you're willing to run a local model or pay per API token β Cline. It has no subscription tier at all β you control cost directly.
- Your code is proprietary, NDA-bound, or under regulatory constraints β Cline with a local model via Ollama or LM Studio is the only one of the four that can run with zero code leaving your machine.
Cursor: Best for Agentic Multi-File Work
Cursor is a VS Code fork built around agent mode, with Composer and Cloud Agents as its flagship features for multi-file, multi-step changes. It supports GPT, Claude, and Gemini models inside the same editor, so you are not locked to one vendor's model.
As of August 2026, Cursor's Hobby tier is free with limited agent requests. Pro, Pro+, and Ultra all share a $20/month base subscription, differentiated by included-usage multipliers (Pro+ gives roughly 3x the Pro agent limit, Ultra roughly 20x) β once included usage is consumed, additional usage is billed on-demand. Teams pricing starts at $40/user/month for the Standard tier, with a Premium tier at 5x the Standard agent limit. Enterprise is custom-priced.
Cursor has a limited-rollout referral program (not a general-purpose affiliate program): eligible referrers get $25 in usage credit per referred paying customer (up to 10 per cycle), and the referred user gets 50% off their first month. This is not a public, universally available commission program β see the Affiliate Program Status section.
Windsurf: Cascade Agent, Now Under Cognition
Windsurf runs the Cascade agent flow and, as of August 2026, costs the same as Cursor Pro β its Pro tier rose from $15/month to $20/month in March 2026, ending what was previously its clearest differentiator (lower price).
Windsurf's free tier includes unlimited Tab autocomplete plus a light daily/weekly quota for Cascade agent use β enough for roughly two to three days of active agentic coding before you hit the limit. In March 2026, Windsurf replaced its old monthly credit-pool system (500 credits/month on Pro) with daily and weekly usage quotas that refresh automatically. Max is $200/month; Teams is $40/user/month; Enterprise is custom.
Windsurf is now owned by Cognition, the company behind the autonomous coding agent Devin, following Cognition's acquisition of Windsurf's team, product, and brand. windsurf.com currently redirects to devin.ai's pricing page, and Devin is being integrated directly into the Windsurf editor rather than replacing it outright.
Windsurf's referral program gives new signups 250 free flex credits via a referral link β a referral incentive, not a commission-based affiliate program.
GitHub Copilot: Best for GitHub/Azure-Standardized Teams
GitHub Copilot is the safest default for organizations already standardized on GitHub, Azure DevOps, or Microsoft's compliance stack, and its coding agent works directly against GitHub Issues and pull requests rather than as a separate editor experience.
GitHub moved Copilot to usage-based AI-credit billing on June 1, 2026, replacing flatter per-seat pricing. As of August 2026: Free tier includes 2,000 completions/month; Pro is $10/month with $15 of included AI credits; Pro+ is $39/month with $70 of included AI credits and access to premium models including Claude Opus; a new Max tier at $100/month includes $200 of AI credits and priority access to new models. For organizations, Business is $19/user/month (1,900 AI credits) and Enterprise is $39/user/month (3,900 AI credits, Enterprise Cloud only) β these two tiers did not change price when usage-based billing rolled out, only the underlying credit accounting did.
GitHub runs a Copilot Partner Program, but it is a technology-integration program for building Copilot Chat extensions, not a pay-per-referral affiliate program β hundreds of companies have joined as technology partners, which is a different relationship than an affiliate paying commission on signups.
Cline: Best Free Option (Bring Your Own Key or Local Model)
Cline is a free, open-source (MIT-licensed) VS Code and JetBrains extension with no subscription tier at all β the extension is completely free for individual developers, confirmed directly on Cline's own pricing/FAQ page.
Cline's billing model is entirely usage-based on the model side: you either purchase inference credits through Cline's own provider routing or bring your own API key from OpenAI, Anthropic, Google, OpenRouter, AWS Bedrock, GCP Vertex, Groq, Cerebras, DeepSeek, and other providers β you pay only for the tokens you use, with no markup from Cline itself.
For $0 total cost, point Cline at a local model server: it connects to Ollama (default endpoint http://localhost:11434) or LM Studio (OpenAI-compatible server on port 1234) with no API key required. Cline's own documentation recommends models like Qwen2.5 Coder, Llama 3.3, DeepSeek Coder V3, or Codestral, and at least a 32K-token context window for reliable multi-step agent behavior β many users running heavier agentic sessions push that to 64K.
Cline has no affiliate or referral program of any kind β it is a community open-source project with no monetization layer to attach one to.
Does Any of These Four Tools Have an Affiliate Program?
As of August 2026, none of the four vendors runs a standard, publicly available, pay-per-referral affiliate program. What each vendor actually offers is narrower than "affiliate program":
- Cursor: a limited-rollout referral program (not universally available) β referrers get $25 usage credit per referred paying customer, referred users get 50% off month one. This is a referral incentive, not a commission-based affiliate program open to publishers.
- Windsurf: a referral link that gives new signups 250 free flex credits. Also a referral incentive, not an affiliate/commission program.
- GitHub Copilot: a "Copilot Partner Program" for building Copilot Chat technology integrations β this is a developer/technology partnership, not a pay-per-referral affiliate arrangement.
- Cline: no referral or affiliate program of any kind; it is a community open-source project.
Frequently Asked Questions
Is Cursor better than GitHub Copilot?
For agentic multi-file work and model flexibility, Cursor is generally the stronger pick β it supports GPT, Claude, and Gemini and its Composer/Cloud Agents handle larger refactors with less manual steering. GitHub Copilot is the better choice specifically for teams already standardized on GitHub Issues, pull requests, and Azure DevOps, since its coding agent works directly against that workflow rather than as a separate editor.
Is there a free AI coding assistant with agent mode?
Yes. Cline is completely free and open source with no subscription tier β you pay only for the LLM API tokens you use, or nothing at all if you connect a local model via Ollama or LM Studio. Cursor and GitHub Copilot both have limited free tiers (Cursor's Hobby tier and Copilot's Free tier with 2,000 completions/month), but agent-mode usage is capped on both.
What is the actual difference between Windsurf and Cursor in 2026?
As of August 2026 the two are priced identically at $20/month for their Pro tiers β Windsurf raised its price from $15 to $20 in March 2026, closing what used to be its main advantage. The remaining difference is workflow: Windsurf uses the Cascade agent flow, Cursor uses Composer and Cloud Agents. Pick based on which agent UX you prefer after trying both, not on price.
Does GitHub Copilot support Claude or Gemini models?
GitHub Copilot Pro+ ($39/month) and Max ($100/month) include access to premium models such as Claude Opus. The base Free and Pro ($10/month) tiers are more limited in model choice. This is narrower than Cursor, which lets Pro-tier users switch between GPT, Claude, and Gemini models directly.
How do I set up Cline with a local model?
Install Ollama or LM Studio, pull a coding model (Cline's docs recommend Qwen2.5 Coder, Llama 3.3, DeepSeek Coder V3, or Codestral), then in Cline choose Ollama or LM Studio as the API provider β Ollama's default endpoint is http://localhost:11434, LM Studio serves an OpenAI-compatible API on port 1234. Neither requires an API key. Use at least a 32K-token context window; heavier agentic sessions often need 64K.
Can I use more than one of these tools at once?
Yes, and many developers do β for example running Cline against a local model for routine, low-sensitivity edits and switching to Cursor or GitHub Copilot for harder problems where a stronger cloud model helps. There is no technical conflict running multiple extensions in the same VS Code install, though only one is typically active as the primary agent per session.
What is the best AI coding assistant for a solo developer on a budget?
Cline paired with a local model (Ollama or LM Studio) costs $0 total. If you want occasional access to a stronger cloud model without a subscription, Cline with a pay-per-token API key (OpenAI, Anthropic, or OpenRouter) keeps cost proportional to actual usage instead of a flat monthly fee.
Do any of these four tools work fully offline?
Only Cline, and only when paired with a local model via Ollama or LM Studio β in that configuration, no code or prompt data leaves your machine. Cursor, Windsurf, and GitHub Copilot are all built around cloud-hosted models by default; Cursor supports pointing at a custom (including local) OpenAI-compatible endpoint, but its core product experience assumes a network connection.
Which tool is best for a team already standardized on GitHub or Azure DevOps?
GitHub Copilot. Its coding agent reads and writes directly against GitHub Issues and pull requests, and Business ($19/user/month) and Enterprise ($39/user/month) tiers add the organizational controls β audit logs, policy management, IP indemnity β that a Microsoft-standardized compliance stack typically requires.
Do Cursor, Windsurf, GitHub Copilot, or Cline pay a commission to writers who recommend them?
No. As of August 2026, none of the four runs a standard public affiliate/commission program. Cursor and Windsurf each offer a limited referral-credit incentive (not open to general publishers), GitHub runs a technology-integration partner program (not pay-per-referral), and Cline is a community open-source project with no monetization layer. This page carries no affiliate relationship with any of the four.
