Caveman is a one-line installable Claude Code skill by Julius Brussee that instructs Claude to respond in ultra-compressed telegraphic language — short imperative verbs, no filler words, minimal articles — while preserving technical accuracy. The conceit is absurd: make Claude sound like a caveman. The result is practical: roughly 75% fewer output tokens per response. This matters because Claude's usage limits are token-based. Power users and teams hitting rate limits on Claude Code subscriptions have found that caveman-style output dramatically extends how many interactions they can run per session. The Hacker News thread hit 333 points the day it launched, with developers sharing variations and reporting measurable drops in token consumption for coding workflows. The project also spawned a fork (Caveman-Claude by om-patel5) that packages it as a higher-performance optimization layer with additional context-compression techniques. What started as a joke about caveman grammar is becoming a serious prompt-engineering pattern for token efficiency.

free-claude-code is a lightweight proxy that intercepts Claude Code's Anthropic Messages API calls and reroutes them to six alternative backends: NVIDIA NIM, OpenRouter, DeepSeek, LM Studio, llama.cpp, and Ollama. From Claude Code's perspective nothing changes — the UX, tool calls, streaming, and reasoning blocks all work identically. Under the hood, you're spending almost nothing. The project supports per-model routing, so you can send Opus traffic to OpenRouter while Haiku goes to a local Ollama instance. It handles the full protocol stack: streaming completions, multi-turn tool use, thinking block pass-through, and request optimization for local hardware. An optional Discord or Telegram bot wrapper lets you trigger remote coding sessions from your phone. With 17K+ GitHub stars and still climbing, this is clearly scratching a real itch. The Anthropic gating of Claude Code behind Pro subscriptions created exactly the market condition this project was built for. Whether it stays ahead of API changes is the open question — but right now it's the fastest path to a near-free Claude Code experience.
Reviewer scorecard
“I tested this against my normal Claude Code sessions and the token reduction is real — closer to 60-70% in practice, but that's still significant. For long refactoring sessions where I'm hitting usage walls, this is now a permanent part of my setup. One-line install is the right distribution model.”
“This is exactly what the indie dev community needed after Anthropic tightened Pro limits. The per-model routing is clever — I can push heavy reasoning to DeepSeek and let fast autocomplete hit a local 8B model. Setup took about 15 minutes.”
“This is a workaround for Anthropic's pricing model, not a solution. The caveman syntax makes outputs harder to read and copy-paste — you'll spend cognitive overhead parsing the response. And if Anthropic changes how usage limits work, this approach becomes irrelevant overnight. It's a clever hack, not a durable tool.”
“This is a proxy built around undocumented client behavior — any Claude Code update could break it silently. Running your codebase through third-party provider APIs also introduces real IP and data risk. For solo projects it's probably fine; for anything professional, think twice.”
“This is a data point in the larger story about prompt efficiency becoming a discipline. As token costs dominate AI budgets, compressing output without losing semantics will be a genuine engineering skill. Caveman is silly — but the underlying insight about output verbosity being a lever is serious.”
“The fact that 17K people starred this in days is a signal: developers want Claude Code's UX without the lock-in. This kind of proxy layer is how model pluralism actually happens in practice — not through official integrations but through community shims.”
“For any creative workflow — writing, design iteration, content generation — caveman output is actively counterproductive. The compressed style strips the nuance and polish from responses that make AI useful for creative work. This is a developer tool with a very specific use case.”
“If you're not deep in CLI-land, the setup friction is real. But for technical creators who've been priced out of Claude Code Pro, this is a legitimate workaround while the pricing landscape settles.”
