Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Pgvector – vector similarity search for Postgres
I’ve done something similar (heh) in pure Postgres: https://github.com/turbo/pg-costop

Pinecone raises $100M Series B
Why do you use pgvector instead of pgANN? My understanding is pgANN is built with FAISS. When I compared pgvector with FAISS, pgvector was 3-5x slower.

Pgvector – vector similarity search for Postgres
Love it! Need better ANNs approaches in databases, using external servers such as Milvus, faiss is a pita

What are some alternatives?
When comparing pg-costop and pgANN you can also consider the following projects:
Milvus - A cloud-native vector database, storage for next generation AI applications
ann-benchmarks - Benchmarks of approximate nearest neighbor libraries in Python
smlar - PostgreSQL extension for an effective similarity search || mirror of git://sigaev.ru/smlar.git || see https://www.pgcon.org/2012/schedule/track/Hacking/443.en.html
