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.

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.
  • Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
  • LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
  • Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
