PromptStacks is a web-based platform that provides a growing collection of curated prompts, organized by categories, use cases, and performance. Its goal is to help AI developers, designers, and researchers quickly find and adapt high-performing prompts for use in their own LLM applications.
The platform features a community-centered design where users can browse, search, and contribute prompt templates for different tasks—ranging from copywriting and summarization to coding, tutoring, and data extraction. Each prompt is evaluated, rated, and categorized to ensure usability and relevance.

Drawbacks
Limited Workflow Features: PromptStacks does not support chaining, testing, or deploying prompts like PromptMixer or LangChain.

Early-Stage Development: As a newer platform, the prompt library is still growing and lacks advanced curation tools.
Comparison with Other Tools
PromptStacks vs. PromptBase
PromptBase is a marketplace where prompt creators can sell their templates. In contrast, PromptStacks is fully free and open-source, focusing on community sharing rather than monetization.
PromptStacks vs. FlowGPT
FlowGPT also offers community-generated prompts but focuses more on direct use with OpenAI’s interface. PromptStacks emphasizes curation, simplicity, and a clean, distraction-free UI.
PromptStacks vs. PromptHero
PromptHero is tailored for image generation prompts (like Midjourney and Stable Diffusion), whereas PromptStacks is more general-purpose and text-focused, making it ideal for GPT-4 or Claude users.
