However, it犺 ## Choose when ### Choose prompttools if… - prompttools is primarily Python; caveman is JavaScript. - License: prompttools is Apache-2.0, caveman is MIT. - Pricing: PromptsTools is open-source under the Apache-2.0 license, making it free to use but with no official support available.. - Tags unique to prompttools: llms, embeddings, deep-learning, machine-learning. - Also covers Vector Databases. - Prompttools aims to support developers in the testing and experimentation of prompts for language models as well as integrating vector databases through Python utilities. ### Choose caveman if… - caveman is primarily JavaScript; prompttools is Python. - License: caveman is MIT, prompttools is Apache-2.0. - Tags unique to caveman: caveman, ai, tokens, 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 prompttools - Last GitHub push was 151 days ago (slowing maintenance, Feb 11, 2026). Validate activity before betting a new project on prompttools. - 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. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ## 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 prompttools and caveman? prompttools: Open-source tools for prompt testing and experimentation. caveman: Reduce token usage with concise 'caveman'-style prompts..
