However, it犺 ## Choose when ### Choose VectorCode if… - VectorCode is primarily Python; caveman is JavaScript. - Tags unique to VectorCode: embeddings, mcp, mcp-server, neovim-plugin. - Also covers Vector Databases. ### Choose caveman if… - caveman is primarily JavaScript; VectorCode is Python. - 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. ## When NOT to use VectorCode - Last GitHub push was 139 days ago (slowing maintenance, Feb 23, 2026). Validate activity before betting a new project on VectorCode. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ## 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. ## Common questions ### What is the difference between VectorCode and caveman? VectorCode: A code repository indexing tool to supercharge your LLM experience.. caveman: Reduce token usage with concise 'caveman'-style prompts..
