Battle of the AI Coding Agents: Claude Code vs OpenAI Codex vs Qwen Coder (February 2026)

#ai #opensource #github #coding

The AI coding wars just got interesting. February 2026 has seen three major players launch or expand their autonomous coding agents: Claude Code's web interface (claude.ai/code), OpenAI's brand new Codex macOS app, and the game-changing arrival of Qwen Coder (coder.qwen.ai) — an open-source, completely free alternative that does everything Claude Code does, but without the subscription fee.

Let's break down what just happened and why Qwen Coder might be the most disruptive launch of 2026.

Table of Contents

What Changed in February 2026

February 2, 2026: OpenAI launches the Codex macOS app — a native desktop application for managing multiple coding agents in parallel.

February 2026: Qwen launches coder.qwen.ai — a web-based coding agent that directly competes with Claude Code Web, but it's completely free and open-source.

This isn't incremental improvement. This is disruption.

The Three Contenders

Claude Code Web (claude.ai/code)

What It Is:
Anthropic's web-based coding agent. Connect your GitHub, point it at a repo, give it a task, and watch it create branches, write code, run tests, and submit PRs — all whilst you're away from your desk.

Launch: October 2025

Cost: Paid

Platform: Web browser, CLI

OpenAI Codex App

What It Is:
A native macOS desktop application that serves as a "command center" for multiple parallel AI coding agents. Each agent gets its own isolated worktree, allowing simultaneous work on different features.

Launch: February 2, 2026

Cost: Paid

Platform: macOS only (Windows/Linux coming)

Qwen Coder (coder.qwen.ai)

What It Is:
Here's where it gets interesting. Qwen Coder is a web-based coding agent that works exactly like Claude Code Web — connects to GitHub, creates branches, writes code, submits PRs — but it's completely free and open-source.

Launch: February 2026

Cost: FREE (with generous usage limits)

Platform: Web browser, CLI

The Qwen Coder Bombshell

Let me be crystal clear about what just happened: Alibaba's Qwen team just open-sourced the entire Claude Code Web experience.

What Qwen Coder Does

✅ Web-based interface at coder.qwen.ai (no installation required)
✅ Direct GitHub integration via OAuth
✅ Autonomous coding — give it a task, it creates branches automatically
✅ Pull request generation — writes code, commits, and opens PRs
✅ Repository understanding — 256K token context window (extendable to 1M)
✅ Asynchronous work — runs tasks whilst you're offline
✅ MCP support — connect to external tools
✅ Skills & subagents — reusable workflows

The Kicker

All of this is:

  • FREE (2,000 requests per day with OAuth)
  • Open-source (Apache 2.0 licence)
  • Self-hostable (run your own instance)
  • No vendor lock-in (you control everything)

This is the equivalent of GitHub releasing a free, open-source alternative to GitHub Copilot that works just as well. It's that significant.

Pricing Reality Check

Claude Code Web

  • Pro Plan: ~£15-17/month (approximately $20 USD)
  • Max 5x: ~£70-85/month (approximately $100 USD)
  • Max 20x: ~£140-170/month (approximately $200 USD)
  • Weekly usage limits apply

Annual Cost: £180-2,040 (approximately $240-2,880 USD)

OpenAI Codex App

  • ChatGPT Plus: ~£17/month (approximately $20 USD)
  • Temporary free access (promotional period)
  • 5-hour rolling limit (doubled during promo)
  • macOS only (major limitation)

Annual Cost: £204 (approximately $240 USD) + macOS requirement

Qwen Coder

  • FREE tier: 2,000 requests per day
  • Self-hosting: FREE (run your own)
  • DashScope API (if you exceed free tier): ~£0.25-0.50 per 1M tokens (approximately $0.35-0.60 USD)

Annual Cost: £0 (approximately $0 USD)

The Math

For a solo developer using Claude Code Pro:

  • Claude Code: £180/year (approximately $240 USD)
  • Codex App: £204/year (approximately $240 USD) + must buy a Mac
  • Qwen Coder: £0/year (approximately $0 USD)

For a team of 5 developers:

  • Claude Code: £900-10,200/year (approximately $1,200-14,400 USD)
  • Codex App: £1,020/year (approximately $1,200 USD) + 5 Macs
  • Qwen Coder: £0/year (approximately $0 USD)

This isn't a small difference. This is game-changing.

Performance Benchmarks

SWE-Bench Verified (Real GitHub Issues)

Model Score Notes
Claude Opus 4.5 80.9% Industry leader
GPT-5.2-Codex 80.0% Close second
Qwen3-Coder-480B 69.6% Best open-source model

Qwen trails by ~11 percentage points compared to Claude, but it's completely free and open-source. For many workflows, that trade-off is absolutely worth it.

Context & Efficiency

Context Windows:

  • Claude Code: 200K tokens (1M extended)
  • Codex App: 400K tokens
  • Qwen Coder: 256K tokens (1M extended)

Token Efficiency:

  • Claude Code: More verbose (thorough reasoning)
  • Codex App: Most efficient
  • Qwen Coder: Efficient with context caching (80% cost reduction on repeated content)

Real-World Performance

What Developers Are Saying:

From early testers (February 2026):

  • "Qwen Coder handles 80-90% of tasks as well as Claude Code"
  • "For refactoring and bug fixes, it's indistinguishable"
  • "Complex architectural decisions might need more guidance"
  • "But it's FREE, so who cares?"

Reality Check:
Qwen3-Coder performs comparably to Claude Sonnet 4.0 or GPT-4 Turbo — very capable, but may need more iteration on highly complex tasks compared to Claude Opus 4.5.

For most real-world development work (bug fixes, feature implementation, refactoring, test generation), the performance difference is negligible.

Real-World Use Cases

When to Choose Claude Code Web

Best For:

  • Mission-critical production code requiring highest accuracy
  • Teams with budget for subscriptions
  • Enterprises needing support contracts
  • Complex architectural refactoring

The Business Case for Qwen Coder

For Startups

Scenario: 3-person startup building MVP

Claude Code:

  • Cost: £45-51/month (approximately $60-72 USD)
  • Annual: £540-612 (approximately $720-864 USD)

Codex App:

  • Cost: £51/month (approximately $60 USD) + 3 Macs (£3,000+ or approximately $4,000+ USD)
  • Annual: £612 + hardware (approximately $720 USD + hardware)

Qwen Coder:

  • Cost: £0 (approximately $0 USD)
  • Annual: £0 (approximately $0 USD)

Savings: £612+ per year (approximately $720+ USD per year)

That's a few months of runway extended. For a startup, that's huge.

For Agencies

Scenario: 15-person dev agency

Claude Code:

  • Cost: £225-2,550/month (approximately $300-3,600 USD/month)
  • Annual: £2,700-30,600 (approximately $3,600-43,200 USD)

Codex App:

  • Cost: £255/month (approximately $300 USD/month) + 15 Macs
  • Annual: £3,060 + hardware (approximately $3,600 USD + hardware)

Qwen Coder:

  • Cost: £0 for most usage, or self-host for unlimited
  • Annual: £0 (approximately $0 USD)

Savings: £2,700-30,600 per year (approximately $3,600-43,200 USD per year)

That's an entire junior developer's salary saved.

For Enterprises

Scenario: 200-person engineering org

Claude Code Enterprise: Custom pricing (likely £20,000-100,000+/year or approximately $28,000-140,000+ USD/year)

Qwen Coder Self-Hosted:

  • Infrastructure costs: £2,000-10,000/year (approximately $2,800-14,000 USD/year)
  • Complete data sovereignty
  • Unlimited usage
  • Full customisation

Savings: Tens of thousands to hundreds of thousands per year

The Catch (There's Always a Catch)

What Qwen Coder Trades Off

1. Slightly Lower Performance

  • 69.6% vs 80.9% on SWE-Bench
  • May require more iteration on complex tasks
  • Not quite Opus 4.5 level (more like Sonnet 4.0)

2. Newer Platform

  • Launched February 2026 (brand new)
  • Smaller community (for now)
  • Fewer tutorials and examples (for now)

3. No Enterprise Support Contracts

  • Open-source means community support
  • No SLAs (unless you pay for support)
  • You're responsible for self-hosting

4. Less Polished (Maybe)

  • Claude Code has 6 months of polish
  • Codex has OpenAI's resources
  • Qwen Coder is newer (but fast-improving)

Is It Worth It?

For 90% of developers: Absolutely yes.

Unless you're:

  • Building mission-critical infrastructure for Netflix
  • Have unlimited budget
  • Need guaranteed enterprise support
  • Require the absolute highest model performance

...then Qwen Coder is the obvious choice.

My Personal Recommendation

Default Choice: Start with Qwen Coder

Seriously. It's free. It's open-source. It works on any device. For 90% of coding tasks, it's indistinguishable from Claude Code.

Try this workflow:

  1. Use Qwen Coder for:

    • Bug fixes
    • Feature implementation
    • Refactoring
    • Test generation
    • Documentation
    • Daily development work

  2. Upgrade to Claude Code for:

    • Critical architecture decisions
    • Complex system refactoring
    • When you need the absolute best

  3. Use Codex App for:

    • Parallel feature development on Mac
    • When managing multiple agents simultaneously

Most developers will spend 90% of their time in Qwen Coder and occasionally upgrade to Claude for the hardest 10%.

This gives you the best of both worlds:

  • Save money on routine work (Qwen is free)
  • Pay for premium quality only when you need it (Claude)

The Bigger Picture

What Qwen Coder Means for AI Development

This is bigger than just a free tool.

Qwen Coder proves that:

  1. Open-source can compete with proprietary AI
  2. Performance gaps are narrowing (69.6% vs 80.9% is close)
  3. Free tiers can be generous (2,000 requests/day!)
  4. Self-hosting is viable (enterprises can own their infrastructure)
  5. Vendor lock-in is avoidable (Apache 2.0 means freedom)

The Pressure on Claude & OpenAI

With Qwen offering 85-90% of the functionality for free, Claude and OpenAI must now justify their subscriptions through:

  • Highest model performance
  • Enterprise features
  • Support contracts
  • Additional integrations

They can't compete on price. So they'll compete on quality and service.

This is healthy competition. Everyone improves.

Closing Thoughts

February 2026 will be remembered as the month AI coding agents went mainstream:

  • OpenAI launched the Codex desktop app (February 2)
  • Qwen dropped the bombshell of free, open-source web coding (February 2026)
  • Claude continues refining its premium experience

We've moved from "Can AI write code?" to "Which free AI coding agent should I use?"

The answer for most developers is clear: Qwen Coder.

It's free. It's open-source. It connects to GitHub. It creates branches and PRs. It works on any device. And it's good enough for 90% of coding tasks.

Start there. Upgrade to Claude only when you need the extra 10-15% performance. Use Codex if you're all-in on Mac.

The future of coding is agentic, asynchronous, and now it's also free.

Welcome to 2026.
