aka Emerging Architectures for LLM Applications
This is a list of available tools, projects, and vendors at each layer of the LLM app stack.
Our original article included only the most popular options, based on user interviews. This repo is meant to be more comprehensive, covering all available options in each category. We probably still missed some important projects, so please open a PR if you see anything missing.
We also included Perplexity and Cursor.sh prompts to make searching and markdown table formatting easier.

We were able to partialy automate this - particularly finding Github and PyPI links - using this Perplexity search prompt. It worked roughly ~75% of the time and could handle ~3 projects at a time, pulling data from 20-30 sources in each iteration.
Once you have the data you would like to add, if you don't want deal with the markdown formatting here, it is easy to correctly format using a tool like Cursor.
See the prompt below that works as an inline edit, just make sure you highlight 4-5 previous examples so Cursor can infer the format itself:
