However, it犺 ## Choose when ### Choose caveman if… - caveman is primarily JavaScript; tome is Svelte. - License: caveman is MIT, tome is Apache-2.0. - Tags unique to caveman: ai, anthropic, caveman, claude code. - When you need to significantly cut down on token usage in AI interactions, up to 65%, without losing essential information content. ### Choose tome if… - tome is primarily Svelte; caveman is JavaScript. - License: tome is Apache-2.0, caveman is MIT. - Tags unique to tome: gemini, llm, llm-client, llms. - Also covers Inference & Serving. ## When NOT to use caveman - When requiring complex and detailed prompts that necessitate more nuanced expression beyond simple, 'caveman'-style sentences. - For situations where adherence to formal or specific linguistic structures is mandatory for the task's success. ## When NOT to use tome - Last GitHub push was 267 days ago (slowing maintenance, Oct 20, 2025). Validate activity before betting a new project on tome. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ## Common questions ### What is the difference between caveman and tome? caveman: Reduce token usage with concise 'caveman'-style prompts.. tome: a magical LLM desktop client that makes it easy for *anyone* to use LLMs and MCP.
