“Run Claude Code 100% free” is a popular promise, and it’s mostly true — with honest caveats. There are three real routes to using Claude Code at little or no cash cost in 2026: free trial credits, free model tiers on aggregators, and local models on your own hardware. None is an unlimited free lunch, but together they cover learning, light use, and privacy-focused work.
This lays out each route, what “free” actually means, and when a cheap paid plan is the smarter move. For the paid-but-cheap options, see use cheap AI models with Claude Code.
Route 1: Free trial credits
Most providers hand out trial credits, and some run free windows for new models — GLM, Kimi, and Xiaomi MiMo have all offered free access through coding tools at launch. This gives you the best quality for free, while it lasts.
Point Claude Code at the provider’s Anthropic-compatible endpoint with your trial key:
export ANTHROPIC_BASE_URL="https://api.z.ai/api/anthropic"
export ANTHROPIC_AUTH_TOKEN="your-trial-key"
export ANTHROPIC_MODEL="glm-5-turbo"
claudeRoute 2: OpenRouter free tiers
OpenRouter exposes some models with free tiers (often rate-limited variants). Through Claude Code Router, you can route Claude Code to one of these at no cash cost:
{
"Providers": [
{
"name": "openrouter",
"api_base_url": "https://openrouter.ai/api/v1/chat/completions",
"api_key": "$OPENROUTER_API_KEY",
"models": ["a-free-tier-model"],
"transformer": { "use": ["openrouter"] }
}
],
"Router": { "default": "openrouter,a-free-tier-model" }
}Free tiers are rate-limited and can be slower or rotate availability, so they suit occasional use. See OpenRouter vs direct API.
Route 3: Local models (no API bill at all)
Running a model locally with Ollama has no per-token cost — you pay in hardware and electricity. Through Claude Code Router you can route Claude Code to a local model:
{
"Providers": [
{
"name": "ollama",
"api_base_url": "http://localhost:11434/v1/chat/completions",
"api_key": "ollama",
"models": ["qwen2.5-coder:latest"]
}
],
"Router": { "default": "ollama,qwen2.5-coder:latest" }
}This is genuinely free of API bills and fully private. The trade-off is quality and speed are capped by your machine — see run DeepSeek locally with Ollama + Claude Code.
The three free routes compared
| Free trials | Best quality; temporary; great for evaluating |
|---|---|
| OpenRouter free tiers | No cash cost; rate-limited; occasional use |
| Local (Ollama) | No API bill; private; limited by your hardware |
When to just pay (a little)
Here’s the honest part: for sustained, serious coding, fighting free limits costs you more in time than a cheap plan costs in money. A GLM Coding Plan from $18/month or DeepSeek pay-per-token at cents per session removes the rate limits and quality ceiling. Use free routes to learn and evaluate; switch to cheap-paid once you’re working daily.
Getting Claude Code running for free
- Grab provider free trials/windows for best quality
- Set up OpenRouter free tiers via Claude Code Router
- Run a local model with Ollama for zero API cost
- Use WSL for smoother setup
- Move to a cheap plan once usage gets heavy
Wrapping up
You can run Claude Code for free in 2026 via trial credits (best quality, temporary), OpenRouter free tiers (rate-limited, occasional), or local models (no API bill, hardware-limited). All three work through an Anthropic endpoint or Claude Code Router. Just be clear-eyed: free means limited, and for daily work a cheap plan beats wrestling with caps.
