Integration improves accuracy and supports token-level embedding
The best features FAISS offers for my team include seamless integration with Colbert and the ability to use FAISS via the Ragatouille framework, which is tailor-made for using the Colbert model. Feature-wise, FAISS allows for more accurate result retrieval, and retrieval speed is also good when comparing the index size. Regarding features, I also emphasize that the usability of FAISS is very seamless, particularly its integration with Colbert and Ragatouille. FAISS has positively impacted my organization by helping us increase the accuracy of retrieval documents; when we store documents in token-level embedding, the accuracy will be high. Additionally, we do not need any external server to host FAISS, allowing us to integrate it with our backend framework, making it a very flexible framework.

Semantic search has transformed client sites and drives faster projects with higher conversions
Adapting to Supabase Vector was relatively smooth, but there was definitely a moderate learning curve at the start. The SQL foundation, REST API, documentation, and integration with all the AI tools made it easier. However, understanding embeddings, index types, similarity metrics, and how SQL and vector hybrid queries work, as well as the RLS policies for vectors, required some time to learn. I do not have many things to point out, but a couple of areas for improvement come to mind. For index optimization guidance, clearer instructions on when to use IVFFlat versus HNSW indexes would be helpful. Additionally, having a built-in embedding generation capability would simplify the workflow, as currently, I use external services such as OpenAI or Hugging Face for that purpose.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product has better performance and stability compared to one of its competitors."
"I used Faiss as a basic database."
"The platform's role-level security feature is quite effective for spatial data management."
"Using Supabase Vector, I was able to set it up in a couple of days, got it validated, and started working on building up the algorithm on top of that."
"Supabase Vector positively impacts my organization by reducing the cost of the LLMs."
"Supabase Vector positively impacts my organization through major improvements in search relevance, faster development speed, a simpler architecture, and reduced engineering overhead, with better performance in real queries due to the hybrid SQL plus vector search."
"I feel Supabase Vector is doing a very great job in reaching out to companies and helping them, and I believe every new entrepreneur who wants to build their own software product should be using Supabase Vector because I think it's the best vector database out there."
"We completed what we initially estimated as a fifteen-day job in just three days, thanks to the Supabase dashboards and triggers."
"The most valuable part using Supabase Vector is how complex things I was able to build and deploy in a short period of time."
"Supabase Vector is easy to set up and cost-effective because the alternative is Firebase, which requires a credit card."

Cons

"It would be beneficial if I could set a parameter and see different query mechanisms being run."
"One of the drawbacks of Faiss is that it works only in-memory. If it could provide separate persistent storage without relying on in-memory, it would reduce the overhead."
"It could be more accessible for handling larger data sets."
"One area for the solution improvement is the inclusion of more sample code in various programming languages, particularly PHP."
"Adapting to Supabase Vector was relatively smooth, but there was definitely a moderate learning curve at the start."
"For advanced production use with millions of embeddings, it's necessary to be thoughtful about indexing such as HNSW or IVFFlat and hardware sizing to keep query times fast."
"My experience with Supabase Vector's performance at scale indicates that it operates excellently at small scales, but as we move toward larger scales, such as multi-million vectors, it requires careful engineering to maintain predictable performance, with challenges such as query plan complexity and latency variance."
"I feel Supabase Vector can be improved by venturing further into adding more backend features and maybe working with fast API frameworks like Python languages; they could improve and widen their capabilities."
"When setting up a database, a PostgreSQL instance, which is the most popular use of Supabase, instead of having to go and write and run an SQL line to create a pgvector on Supabase, it would be nice if the person creating the database for the project could just be asked with maybe a checkbox whether they want a vector database or not."
"I think the support system can be better because after Supabase Vector stopped working in India, there is no support."
"When the website goes down, the lagging part needs to be resolved. When you have attached a front-end app and your users are using it and then the back-end is not in sync or lagging at the moment, it usually affects the front end of the app because the app will not be able to function to its maximum expectation."
