GitHub Copilot Alternative 2026: GLM Coding Plan Compared (Pricing, Quotas, Access)

Looking for a GitHub Copilot alternative in 2026? You are not alone, and the reason is unusual: GitHub itself paused new sign-ups for Copilot Pro, Pro+, and Max on April 20, 2026. Existing subscribers keep working, but the front door for new paid accounts is closed until further notice, according to GitHub's official plans documentation.

This comparison was checked against both vendors' official pricing pages today (September 9, 2026). No recycled 2024 numbers.

The Two Candidates

GitHub Copilot is the first-party AI assistant from GitHub/Microsoft: one subscription covering editor integration, models, and interface, deeply wired into VS Code and the GitHub platform.

GLM Coding Plan (from Z.ai) takes the opposite approach: you subscribe to access to the GLM model family (currently GLM-5.3), then plug it into the coding tools you already use, including Claude Code, Cline, Roo Code, OpenCode, Cursor, and Zed, through an Anthropic-compatible endpoint. Your workflow stays; the model and the bill change.

Pricing Compared

Aspect	GLM Coding Plan	GitHub Copilot
Entry tier	Lite, from ~$18/month	Free tier (limited)
Mid tier	Pro	Pro, $10/month (standard price)
Top tier	Max	Pro+ $39/month, Max higher
Overages	None, plan quota	AI credits at $0.01/credit after the allowance runs out
New sign-ups	Open	Paused for paid tiers (since April 20, 2026)

Copilot's standard prices occasionally run promotions, so check the official page at checkout.

Quotas: Credits vs Flat Windows

This difference matters more than most reviews admit.

Copilot uses AI credits. Each plan includes a monthly allowance, premium models consume credits faster, and you top up when it runs dry. Flexible, but your monthly bill can swing depending on which models you lean on.

GLM Coding Plan uses time-windowed quotas (for example, a fresh allowance every 5 hours on the Lite tier) with no surprise charges. For long debugging sessions, large refactors, or a 48-hour hackathon sprint, flat is far easier to budget. You know the maximum spend before you start.

Supported Tools and Integration Depth

Copilot's moat is integration depth: VS Code, GitHub PR summaries, Copilot CLI, and the whole GitHub ecosystem. If your team lives inside GitHub issues and pull requests all day, this remains a genuine advantage.

GLM Coding Plan is tool-agnostic. Because it exposes OpenAI- and Anthropic-compatible endpoints, it works with anything that speaks those protocols, and Z.ai maintains setup guides for 16+ tools. If you already use Claude Code or Cline and just want cheaper model access, nothing about your workflow needs to change. Our full GLM Coding Plan review walks through per-tool configuration.

Model Quality: Test It Yourself

GLM-5.3 is an open-weight model positioned in the coding-reasoning class. We will not claim it beats every proprietary model at everything; that claim would not survive contact with a real benchmark suite. What we can say from daily usage: for everyday coding tasks (refactoring, writing tests, explaining code, scaffolding), it is productive at a cost far below premium AI tool subscriptions.

The most honest way to decide: take one real bug from your own codebase, run it through both services in parallel (Copilot Free is still open for sign-up), and count the revision rounds each one needs. Ten minutes of that beats any benchmark table.

Which One Should You Pick?

Choose the GLM Coding Plan if you:

• Want to keep using Claude Code, Cline, or Cursor without expensive API bills
• Prefer flat, predictable costs for budgeting
• Do not have a paid Copilot seat and cannot get one right now
• Need OpenAI/Anthropic-compatible endpoints for your own projects and agents

Stick with GitHub Copilot if you:

• Already had a paid account before April 2026 (it continues to work normally)
• Live in GitHub PR and issue automation workflows
• Need a vendor with Microsoft's enterprise compliance stack

FAQ

Is the GLM Coding Plan made by Anthropic or GitHub? No. It is a product from Z.ai, a separate company. It provides endpoints that are compatible with those tools, including Claude Code, but it is not affiliated with either vendor.

When will Copilot paid sign-ups reopen? GitHub says "temporarily paused" with no end date. Watch the official docs page.

Is GLM-5.3 open weight? Yes, the latest GLM family is open weight, and the Coding Plan gives you API access to it without self-hosting.

Can I try before paying? Copilot has a Free tier. The GLM Coding Plan sometimes runs first-order promotions (a 10% discount with a limited claim window appeared recently); check the terms at checkout.

The Bottom Line

The 2026 comparison is not about which model is smarter. It is about access and cost structure. With paid Copilot sign-ups paused for new accounts, the GLM Coding Plan is the most practical way in for developers who want to start today, at a lower and more predictable monthly cost. Existing Copilot subscribers with heavy GitHub workflows? Stay where you are; the integration depth is real.
