In 2026, the battleground for AI coding tools has shifted from "the tool itself" to "the subscription plan." A year ago, choosing Cursor or Tongyi Lingma was about the IDE experience; now the real dilemma is: which plan should your 20 dollars a month go to? Cursor Pro, Claude Code, Windsurf Pro, OpenAI Codex, plus Zhipu's GLM Coding Plan-which just had all user quotas fully reset on 8/11-five mainstream AI coding plans, each backed by a completely different set of models, quotas, and ecosystem logic. This review compares one thing only: what your money actually buys.
Scope first. This site has already published two related reviews: the AI Coding IDE Comparison (comparing IDE form factors and features, Cursor, Trae, Qoder, etc.) and the AI Terminal Coding Agent Comparison (comparing CLI agent autonomy, Claude Code, Codex CLI, Aider, etc.). This is the third piece, focused exclusively on subscription plans: not whether the IDE UI is pretty, not whether CLI commands are smooth, just quotas, pricing, included models, and use cases. Below is compiled from each platform's official site and public information, as of 2026-08-11. Closed-source pricing is uniformly "per official site," no invented quota numbers. This is a representative comparison, not a personal full-scale benchmark. This site also published the ZCode upgrade GLM Coding Plan quota reset hotspot (this batch's hotspot piece), the crush coding agent open-source resource (open-source piece), and the AI coding context engineering SOP (how to use after picking a plan). This piece covers the "plan selection" step.
One: Know the Difference: A Coding Plan Is Not a Tool, It's a Subscription
Three easily confused concepts, demarcated first. AI Coding IDE: you download an editor with built-in AI completion and chat; what you compare is editor experience and plugin ecosystem. This site's IDE comparison covers this. AI Coding Agent: an autonomous agent running in the terminal or background; given a task, it modifies files and runs commands itself; what you compare is autonomy and model binding. This site's CLI agent comparison covers this. AI Coding Plan: the subscription tier you pay for monthly; the core question is "for this money, how much quota do I get, which models can I call, and in which tools can I use them." What you compare is subscription value and quota logic. This piece only compares the third category.
Why pull it out separately? Because by 2026, plan pricing has gotten complex enough to be confusing. Some bill by 5-hour rolling windows, some cap by request count, some lock the strongest models behind higher tiers, some tie quotas to their own IDE. The same "20 dollars/month" buys wildly different things on different platforms. So this piece doesn't compare tool features, only the real money inside the plan.
Two: Five-Plan Side-by-Side Comparison
Five representative plans, compared across backing model or tool, subscription price, highlights, and China availability. Closed-source pricing is uniformly "per official site."
| Plan | Backing model or tool | Subscription price | Highlights | China availability |
|---|---|---|---|---|
| Zhipu GLM Coding Plan | GLM series + ZCode | Per official site | Domestic, tied to ZCode, 8/11 full quota reset, multi-tool compatible | Available (domestic) |
| Anthropic Claude Code | Claude Sonnet/Opus | Pro $20/mo, Max $100/$200/mo (per official site) | Strongest agentic depth, code quality gold standard | Restricted, needs VPN |
| Cursor Pro | Cursor IDE (multi-model) | ~$20/mo (per official site) | VS Code ecosystem, multi-model switching, complete IDE experience | Restricted (network) |
| Windsurf Pro | Windsurf IDE (Codeium) | ~$15/mo (per official site) | Value, Cascade agent flow, all-in-one IDE | Restricted (network) |
| OpenAI Codex | GPT series | With ChatGPT Plus $20/Pro $200 (per official site) | Bundled with ChatGPT, OpenAI ecosystem, CLI + cloud | Unavailable |
A few takeaways. First, the five plans represent five strategies: GLM bets on domestic availability, Claude Code bets on agentic depth, Cursor bets on IDE ecosystem, Windsurf bets on value, and Codex bets on the OpenAI ecosystem. Second, "subscription price" is just the entry ticket. What truly determines experience is the quota logic: 5-hour rolling windows, request-count caps, credit-point systems, each with different algorithms. Specific quotas are per official site; don't trust secondhand numbers. Third, China availability is a hard dividing line: GLM is the only domestically available option; the other four are all restricted or unavailable.
Three: One by One: Each Plan's Best Range
Zhipu GLM Coding Plan: the only domestic option, tied to ZCode. Zhipu's coding plan, bound to its in-house ZCode tool, backed by the GLM model series. On 8/11 all user quotas were fully reset (covered in this batch's hotspot piece, see the ZCode upgrade hotspot), making it the most-watched domestic plan. Strengths: domestic availability plus compatibility with multiple tools (Cursor, Cline, Roo Code, and other mainstream tools all work) plus MCP tool support. Developers in China need no VPN and no payment hassle. Shortcomings: GLM models still trail Claude/GPT in complex multi-step reasoning, and ZCode's ecosystem maturity lags VS Code-based tools. Best for: developers in China, compliance-friendly use, multi-tool switching. Pricing per official site. China availability: available, domestic.
Anthropic Claude Code: code quality gold standard, deepest agentic capability. Anthropic's plan is delivered via Claude Pro/Max subscriptions, backed by Claude Sonnet/Opus models. Pro tier is $20/month; Max tiers are $100/month and $200/month (per official site), with different tiers corresponding to different usage limits. Strengths: code quality and agentic depth are consensus first-tier. Long context, complex multi-step refactoring, cross-file understanding: Claude's reasoning is the current benchmark. Shortcomings: highest price, closed-source, model not swappable, and requires VPN in China. Best for: developers and teams pursuing top code quality, complex refactoring, with budget to spare. China availability: restricted, API needs VPN.
Cursor Pro: VS Code ecosystem moat, the IDE plan benchmark. Cursor's subscription tier, ~$20/month (per official site), essentially buying quota to call multiple models (Claude, GPT, etc.) inside a modified VS Code. Strengths: complete VS Code plugin ecosystem, flexible multi-model switching, smoothest IDE experience. If you're a VS Code veteran, migration cost is lowest. Shortcomings: quotas get tight under the 5-hour rolling window with heavy use, pricing is opaque, and China network is restricted. Best for: heavy VS Code users, multi-model switching, IDE-workflow developers. China availability: restricted, unstable network.
Windsurf Pro: the value tier, all-in-one IDE. Windsurf's (formerly Codeium) subscription, ~$15/month (per official site), the lowest entry price of the five. Strengths: value plus Cascade agent flow (runs multi-step tasks in one go) plus integrated IDE experience. Shortcomings: model capability and ecosystem trail Cursor and Claude Code, smaller community. Best for: budget-conscious independent developers wanting an all-in-one IDE agent experience. China availability: restricted, unstable network.
OpenAI Codex: bundled with ChatGPT, OpenAI ecosystem. OpenAI's coding capabilities come with ChatGPT Plus ($20/month) and Pro ($200/month) subscriptions (per official site), including Codex CLI and cloud Codex. Strengths: GPT series model capability plus OpenAI ecosystem integration plus dual CLI and cloud form factors. Shortcomings: unavailable in China, model locked to OpenAI, and coding isn't the only selling point of a ChatGPT subscription (quota is shared with chat). Best for: existing ChatGPT subscribers, OpenAI ecosystem users. China availability: unavailable.
Four: Pick by Need
Direct conclusions by your need.
| Your need | Top pick | Reason |
|---|---|---|
| Usable in China, no VPN or payment hassle | Zhipu GLM Coding Plan | Only domestic option, 8/11 quota reset, multi-tool compatible |
| Top code quality, complex refactoring | Anthropic Claude Code | Claude model is the code quality gold standard, deepest agentic capability |
| Heavy VS Code user, multi-model switching | Cursor Pro | Ecosystem moat, lowest migration cost |
| Budget-conscious, want all-in-one IDE agent | Windsurf Pro | Lowest entry price, Cascade agent flow |
| Already have ChatGPT subscription, OpenAI ecosystem | OpenAI Codex | Bundled with subscription, CLI + cloud dual form |
| China-available + data stays local | GLM Coding Plan | Only domestic option, no VPN needed |
Most developers' actual combo: use GLM Coding Plan as the primary in China (available plus compliant), switch to Claude Code (needs VPN) as backup for tasks it can't handle. Well-funded teams go straight to Claude Code Max. No need to subscribe to all five. Pick by region and budget.
Five: Three Pitfalls
One: Don't take "monthly fee" as the whole story; quota logic is the real cost. The same 20 dollars/month might give you hundreds of requests on one platform, throttle you with a 5-hour rolling window on another, or lock the strongest model behind a higher tier on a third. A single agent task can trigger a dozen-plus model calls; what seems "enough" can be exhausted in half a day. Before subscribing, read the quota rules on the official site. Don't trust secondhand numbers. Quota policies change fast; today's numbers may be void tomorrow.
Two: Most closed-source plans are restricted in China; don't pay first and find out you can't use it. Of the five, only GLM Coding Plan is domestically available. The other four (Claude Code, Cursor, Windsurf, Codex) all require a VPN or are outright unavailable. Developers in China should confirm network and payment work before subscribing. Don't pay for a year only to find you can't connect. This is the most common and most painful pitfall.
Three: Annual subscriptions carry risk; the market changes too fast. AI coding plan policies shifted rapidly in 2026: quota adjustments, billing-model switches, plan discontinuations have all happened. Prefer monthly billing, even if slightly pricier, to keep the freedom to leave anytime. Data in this article is as of 2026-08-11. Before purchasing, always check each platform's official site for the latest terms.
Six: FAQ
Q: What's the difference between an AI coding plan and an AI coding IDE? A: An IDE is the editor you download, compared by UI and plugin ecosystem (this site's IDE comparison covers that). A plan is the subscription tier you pay for monthly, compared by quota, models, and value (this piece covers that). Many IDEs (like Cursor, Windsurf) are free to download. What you pay for is the quota to call models inside them. That quota is the plan.
Q: Which ones can developers in China use? A: Of the five, only Zhipu GLM Coding Plan is domestically available: no VPN, no payment hassle, and quotas were just fully reset on 8/11. The other four (Claude Code, Cursor, Windsurf, Codex) all require a VPN or are outright unavailable. Developers in China should look at GLM first, then use Claude Code as backup for complex tasks.
Q: What's the difference between Claude Code Pro and Max? A: Pro is ~$20/month; Max has $100/month and $200/month tiers (per official site). The difference is mainly in usage limits. Higher tiers mean more calls within the 5-hour rolling window and access to stronger models. Specific quotas per official site. Heavy users should go Max; light users are fine with Pro.
Q: Cursor and Windsurf are both IDE plans; how do I choose? A: Cursor is ~$20/month, with the most complete VS Code ecosystem and the most flexible multi-model switching, suited for VS Code veterans. Windsurf is ~$15/month, with a lower entry price and a smooth Cascade agent flow, suited for budget-conscious independent developers. Both are closed-source with restricted China networks. For ecosystem pick Cursor; for value pick Windsurf.
Q: Can I skip the plan and configure my own API key? A: Yes. Open-source tools like Aider and OpenHands are free; you plug in any model's API key and pay per use (this site's CLI agent comparison has details). But plans offer predictable quotas, no need to calculate token costs yourself, and smoother tool integration. Heavy users find plans more cost-effective; light users save more with pay-per-use APIs.
