GLM Coding Plan Pricing: The $18 Alternative to Codex and Claude Code
GLM's $18, $80, and $168 coding plans explained, with trial quota details and how they stack up against pricier Codex and Claude Code tiers.
What is the GLM coding plan and what does it cost?
GLM’s coding plan comes in three standard monthly tiers: $18, $80, and $168. Discounted offers show up periodically, so it’s worth checking the billing period before comparing prices, since a lower headline number sometimes reflects an annual or promotional rate rather than the standard month-to-month cost. The plan is used through Zcode, which is free to download, and new users get a trial quota to test GLM before committing to a paid tier.
The pitch is simple: instead of paying $100 or $200 a month for a coding subscription from OpenAI or Anthropic, you get a usable coding agent for less than a fifth of that price at the entry tier.
TL;DR
- The $18 GLM plan is the standout tier, offering enough usage that one reviewer said it deserves consideration even against subscriptions costing five to ten times more.
- GLM’s three tiers ($18, $80, $168) roughly mirror the step-up structure of Codex and Claude Code, but at a fraction of the price.
- Zcode, the app used to run GLM’s coding plan, is free to download, and a trial quota lets new users test the model before paying anything.
- GLM pairs well with Claude Code’s CLI, and supports browser automation so the agent can check its own work by interacting with a live interface, not just mocked tests.
- No direct API-equivalent dollar value has been calculated for GLM the way it has for Codex and Claude Code plans, so comparisons are based on practical usage room rather than a matching cost model.
- The general advice is to start with the smallest plan that covers your workload and upgrade only when you actually hit the ceiling, rather than pre-paying for capacity you might not use.
- For budget-conscious developers, GLM is positioned as the plan to try before jumping to a $100 or $200 monthly subscription.
How does GLM’s pricing compare to Codex and Claude Code?
Codex’s paid tiers run $20 (Plus), $100 (Pro 5X), and $200 (Pro 20X) a month. Claude Code follows a similar shape: $20 (Pro), $100 (Max 5X), and $200 (Max 20X). Both providers advertise roughly five times the usage at the $100 tier and twenty times at the $200 tier relative to their base plan, so the top tier gives more allowance per dollar spent if you can actually use it.
GLM undercuts all of these. Its top tier, $168, still lands below the $200 tier from either competitor, and its entry tier at $18 is roughly half the price of Codex Plus or Claude Pro. The catch is that GLM’s quota system and underlying models are different, so the plans aren’t numerically interchangeable. You’re not getting “half the Codex allowance for less than half the price.” You’re getting a separate ecosystem with its own limits, and by most accounts those limits are generous enough that the $18 tier holds up well against options costing far more.
What do you actually get with GLM’s coding plan?
GLM works with Claude Code, meaning you can use GLM’s models inside a CLI workflow that some developers already prefer over Codex’s desktop-first approach. It also includes browser automation, letting the agent open an interface, click through it, and verify that a fix actually works rather than relying purely on unit tests run against its own mocks. That distinction matters: a model that only checks its work against local tests can report “done” on something that’s actually broken for a real user. Browser-based verification closes part of that gap.
GLM can also sustain longer tasks, working toward a goal over multiple steps rather than needing constant re-prompting. Combined with browser checks, that makes it viable for building something from scratch and then iterating on it, which is the core workflow most people want from a coding subscription in the first place.
Is the $18 plan actually enough for real coding work?
For a lot of everyday coding tasks, yes. The reasoning isn’t based on a formal API-equivalent calculation the way Codex and Claude Code plans were benchmarked (roughly $34 of API-equivalent activity measured against 3% of a weekly Codex allowance, for example). No such calculation has been run for GLM. Instead, the recommendation rests on practical experience: the usage room on the $18 tier is wide enough to build an initial version of something, request changes, and work through bugs without hitting a wall immediately.
That’s a meaningfully different way of evaluating a plan than pure cost-per-token math, but it’s arguably more useful. Running out of allowance mid-task is the actual pain point for most people on a budget, not whether the marginal token costs a fraction of a cent more or less than a competitor’s.
How does the free trial quota work?
Built like a system. Not vibe-coded.
Remy manages the project — every layer architected, not stitched together at the last second.
Zcode is free to download, and it comes with a trial quota that lets new users run GLM without paying for a plan first. This is the natural way to test whether GLM’s coding performance and usage limits fit your workflow before committing to the $18, $80, or $168 tier. Given that the paid tiers are already inexpensive relative to Codex and Claude Code, the trial functions less as a major decision point and more as a quick sanity check: does the model handle your stack, does the browser automation work reliably, and does the CLI integration (via Claude Code) feel comfortable.
Is GLM worth it compared to Codex or Claude Code?
If your primary constraint is budget, GLM is worth trying before paying $100 or $200 a month elsewhere. It’s not a like-for-like replacement for Codex’s image generation, browser and computer use, or Claude Code’s terminal-first experience with Opus and Sonnet. Those subscriptions bring their own model strengths and app-level features that GLM doesn’t attempt to match feature-for-feature.
But for developers whose main problem is running out of usage allowance rather than needing a specific flagship model, GLM’s combination of low price and generous quota makes it a reasonable first stop. The general advice holds regardless of provider: start with the smallest plan that covers your actual workload, and upgrade only once you’re consistently maxing it out. Paying for a bigger allowance you don’t use doesn’t get anything shipped faster.
Frequently Asked Questions
How much does the GLM coding plan cost?
GLM’s standard coding plan pricing has three tiers: $18, $80, and $168 per month. Discounted or promotional pricing appears at times, so check whether a quoted price reflects the standard monthly rate or a limited-time offer.
Is there a free way to try GLM’s coding plan?
Yes. Zcode, the app used to access GLM’s coding plan, is free to download, and new users receive a trial quota to test the model before subscribing to a paid tier.
How does the $18 GLM plan compare to Codex Plus or Claude Pro?
Both Codex Plus and Claude Pro cost $20 a month, slightly more than GLM’s $18 entry tier. The bigger difference is usage room: GLM’s entry tier has been described as generous enough to rival much pricier plans, though the quota systems aren’t directly comparable since the underlying models differ.
Does GLM work with Claude Code?
Yes. GLM integrates with Claude Code’s CLI, which means developers who prefer a terminal-based workflow over a desktop app can use GLM’s models through that interface.
Does GLM include browser automation for testing code?
Yes. GLM supports browser automation that lets it interact with a live interface to check whether a fix or feature actually works, rather than only validating against local unit tests or mocks.
