Run Claude Code for Free: What Viral Videos Don't Tell You

Local AI, Zero Cost — Part 4. Part 1 matched your laptop to the right open model, Part 2 built a free coding assistant in VS Code, and Part 3 added private document chat. This part tackles the claim behind a wave of viral videos: that you can run Claude Code for free.

Your feed has probably served you the video by now. A terminal, the familiar Claude Code welcome screen, and a bold title: “Claude Code is FREE now!” The claim is half true, and the half that’s false is exactly the half the videos skim past. The Claude Code CLI costs nothing to install. The Claude models behind it are never free — but the CLI will happily talk to models that are.

This guide separates the two, shows the one environment variable that makes the whole trick work, and walks through the three setups that actually deliver: a fully free local one, free cloud tiers, and the cheap coding plans that sit in between.

Is Claude Code Really Free? The Honest Answer#

Claude Code is two things wearing one name. The first is a command-line tool — an agent that reads your codebase, edits files and runs commands. That tool installs free in one line:

curl -fsSL https://claude.ai/install.sh | bash

The second is the brain behind it: Claude models served from Anthropic’s API. That part is never free. As of July 2026, Anthropic’s pricing page is explicit. The $0 Free plan covers chat on web and mobile but does not include Claude Code. The cheapest official way in is Claude Pro at $17/month billed annually ($20 monthly). Max plans start at $100/month for 5x Pro usage. Pay-per-token API access runs from $1 per million input tokens for Haiku 4.5 up to $5/$25 per million for Opus 4.8.

So when a video says “Claude Code is free,” read it as: the steering wheel is free; the engine is rented. Bottom line: no video changes Anthropic’s pricing — every “free Claude Code” method swaps the engine, not the bill.

The Trick Behind the Videos: One Environment Variable#

Claude Code talks to its model through the Anthropic Messages API — a plain HTTP format. The CLI doesn’t care who answers, only that the reply follows that format. And Claude Code reads the server address from an environment variable, ANTHROPIC_BASE_URL, which you can point anywhere.

That one setting is the entire viral trick:

export ANTHROPIC_BASE_URL=http://localhost:11434  # or any compatible server
export ANTHROPIC_AUTH_TOKEN=ollama
export ANTHROPIC_API_KEY=""

A whole ecosystem now stands on the other side of that variable. Ollama serves the Anthropic-compatible API from your own machine. DeepSeek hosts an Anthropic-compatible endpoint at https://api.deepseek.com/anthropic. Z.ai’s GLM plans and Moonshot’s Kimi plans do the same. These are official, documented integrations — the providers publish the setup guides themselves.

Bottom line: you keep Claude Code’s agent skills — file edits, subagents, permissions — while any compatible model does the thinking.

The Real Ways to Get Claude Code for Free#

Getting Claude Code for free — actually free, not trial-free — comes down to two routes: run the model yourself, or borrow someone’s free tier.

Option 1: Ollama on your own machine (free forever, private)#

This is the cleanest version of the trick, and since Ollama v0.14 it’s official: Ollama natively speaks the Anthropic API on port 11434. Newer versions collapse the whole setup into one command:

ollama launch claude

That sets the environment variables and opens Claude Code against your local model. Prefer manual control? Export the three variables above, then run claude --model qwen3.5 (or any tool-calling model you’ve pulled). Ollama’s docs recommend a 64k+ context window for real repositories — agentic coding burns context fast.

• Cost: $0, forever. No meter, no rate limit, no account.
• Privacy: total. Your code never leaves the laptop — same story as the local VS Code assistant from Part 2.
• Catch: your hardware is the ceiling. A 7B–14B model handles focused edits well but won’t match cloud models on sprawling multi-file tasks.

Option 2: Free cloud tiers (free-ish, rate-limited)#

No GPU? Two providers hand out enough free inference to matter. NVIDIA’s build.nvidia.com catalog offers hosted open models with a free developer tier. It stars in many of the viral videos for a simple reason: capable GLM and Llama variants cost nothing per request within rate limits. OpenRouter lists models with a :free suffix that cost $0 within daily caps; we covered how its routing works in our OpenRouter review.

One honest wrinkle the videos gloss over: these two speak the OpenAI-style API, not Anthropic’s. So you can’t point ANTHROPIC_BASE_URL at them directly — you run a small open-source translator proxy on localhost and point Claude Code at that. It’s a five-minute detour; Part 5 walks through the exact setup.

Cheap Beats Free: The Coding-Plan Middle Ground#

Here’s what the videos rarely admit: most creators making them don’t stay on free tiers. They land on budget coding plans — flat-rate subscriptions from model providers, built specifically to plug into Claude Code:

• DeepSeek — pay-per-token through its Anthropic-compatible endpoint; routine sessions cost cents rather than dollars.
• GLM Coding Plan (Z.ai) — the breakout of the wave, with promo pricing that started as low as a few dollars monthly; as of 2026 the tiers run roughly $10 (Lite) to $80 (Max) per month.
• Kimi Code (Moonshot) — built on the trillion-parameter K2 line with very long context, again at a fraction of a Claude subscription.

Benchmark comparisons circulating in 2026 generally place the top Chinese open-weight models at 90–95% of Claude’s coding scores. Treat vendor-adjacent numbers with healthy skepticism, but the practical consensus matches. For everyday feature work the gap is small; on the hardest agentic marathons, Claude still leads. That’s why our Cursor vs Claude Code comparison still measures everything against it.

Bottom line: if free tiers feel throttled but $20/month feels steep, a $3–10 coding plan is the honest middle ground the videos are quietly using.

What You Give Up (The Part the Videos Skip)#

Swapping the backend costs you three things, and you should choose knowing all of them.

• Model quality: you lose Anthropic’s models entirely. It’s Claude Code without Claude — the agent scaffolding stays, the frontier reasoning goes. Expect the difference on long refactors, subtle bugs and large-context work.
• Privacy: every cloud option sends your code to that provider’s servers, under that provider’s jurisdiction and data policy. For client work or anything under NDA, that’s a real decision, not a footnote. Only local Ollama (or an official Anthropic plan) keeps the data story simple.
• Support and polish: Anthropic tests Claude Code against Claude. Third-party backends occasionally stumble on tool-calling edge cases, and when they do, you’re debugging the seam yourself.

Which Setup Should You Pick?#

The viral videos aren’t lying, but they’re selling a headline. Claude Code the tool is free and open to any backend — a great deal: a frontier-grade coding agent whose engine you choose. Claude Code the experience the demos promise still costs $17 a month, or a willingness to accept a very good model instead of the best one. Now you know exactly which one you’re getting.
