When working on web projects, you might wonder: “How long will our Next.js version be supported?” This becomes especially critical in production environments where security patches and bug fixes are essential. Today, we’ll explore Next.js version support policies in detail and help you choose the right version for your needs.
1. What is Next.js? The Essential Framework for Modern Web Development
Next.js is an open-source React-based web framework developed by Vercel. First released on October 25, 2016, it has quickly become an industry standard. Global companies like Walmart, Apple, Nike, Netflix, TikTok, Uber, Starbucks, and Spotify use Next.js in production, demonstrating its proven reliability.
Next.js’s biggest advantage is its support for Server-Side Rendering (SSR), Static Site Generation (SSG), and Client-Side Rendering (CSR). Developers can choose or mix rendering methods based on project requirements. It also provides built-in features like Automatic Code-Splitting, optimized production builds, and Fast Refresh for a superior development experience.
2. Next.js License: Freely Available Under MIT License
Understanding licensing is crucial before adopting any framework. Next.js is an open-source project distributed under the MIT License. MIT is one of the most permissive open-source licenses, allowing commercial use, modification, distribution, and private use.
The only requirement when using MIT-licensed software is including the original copyright notice and license text when distributing your software. Remember to include the license notice when deploying projects built with Next.js.
Key MIT License Features:
| Feature | Status |
|---|---|
| Commercial Use | ✅ Allowed |
| Modification & Distribution | ✅ Allowed |
| Private Use | ✅ Allowed |
| License and Copyright Notice | ⚠️ Required |
| Warranty | ❌ None (AS-IS) |
The full license text is available in the Next.js GitHub repository.
3. Understanding LTS: Active LTS vs. Maintenance LTS
Next.js officially introduced its LTS (Long-Term Support) policy in 2024. Under this policy, major versions go through two support phases.
Active LTS
When a new major version is released, it immediately enters Active LTS status and remains there until the next major version is released. During Active LTS, versions receive new features, regular bug fixes, performance improvements, and security patches. This is the most stable phase for production use while still benefiting from the latest features.
For example, Next.js 16 was released on October 21, 2025, making it the current Active LTS version.
Maintenance LTS
When a new major version is released, the previous version transitions to Maintenance LTS and remains in this phase for two years from its initial release date. During Maintenance LTS, only critical bug fixes and essential security updates are provided. No new features are added, but stability and security are maintained.
Notably, updates for Maintenance LTS versions are released as semver-minor releases, even if they include breaking changes.

Maintaining Existing Projects
Version-Specific Recommendations:
| Current Version | Status | Recommended Action | Priority |
|---|---|---|---|
| Next.js 16 | Active LTS | Maintain | – |
| Next.js 15 | Maintenance LTS | Supported until Oct 2026, plan gradual upgrade | 🟢 Medium |

| Next.js 13 or below | EOL | Immediate upgrade required (security risk) | 🔴 Critical |
Enterprise Environments
If stability is paramount, Maintenance LTS versions (Next.js 15) are also viable. However, mark EOL dates on your calendar and establish upgrade plans in advance.
6. Understanding Release Channels: Stable vs. Canary
Next.js operates two release channels.
| Channel | Purpose | Update Frequency | Production Use | Characteristics |
|---|---|---|---|---|
| Stable | Production environments | Regular | ✅ Recommended | Thoroughly tested, semantic versioning |
| Canary | Experimentation & testing | Daily | ❌ Not recommended | Preview latest features, potential bugs |
# Install Canary version (testing purposes only)
npm install next@canary
7. Version Checking and Upgrade Methods
Checking Current Version
# Method 1: Next.js CLI
npx next --version
# Method 2: npm
npm list next
# Method 3: Check package.json
cat package.json | grep "next"
Pre-Upgrade Checklist
| Step | Verification |
|---|---|
| 1 | Review official upgrade guide |
| 2 | Check breaking changes |
| 3 | Verify React and Node.js version compatibility |
| 4 | Test in development environment |
| 5 | Consider using Codemod tools |
Executing Upgrades
# Upgrade to latest version
npm install next@latest react@latest react-dom@latest
# Or use automated upgrade CLI (Next.js 15+)
npx @next/codemod@latest upgrade latest
8. If You Must Continue Using EOL Versions
Alternatives when using EOL versions is unavoidable:
