Boya Uday Kumar

AI Solutions Lead at ADP

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.

Ganaraj Amakrishna

Lead Technical Architect at Zoro UK

Vector search has improved e‑commerce relevance but setup and learning curve still need work

Vespa definitely had its own set of challenges. It was really hard to get into initially, especially when I started implementing it in 2024 along with one junior employee, and the lack of documentation made it difficult. I aimed for an implementation with ColBERT, a sparse embedding mechanism, which I believed would fit well for e-commerce. We went through iterations during A/B testing because the initial set did not work as expected, which extended the process to about one and a half years. Vespa has a considerable learning curve, making it challenging for most people to get into, and it is also expensive, which can deter startups or those with smaller budgets from using it. Community support was decent, and we turned to it for clarifications. However, substantial improvements in documentation are necessary, especially more examples for handling DSL effectively. Having a runtime testing feature would greatly facilitate quick iterations.

Quotes from Members

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

Pros

"Supabase Vector is easy to set up and cost-effective because the alternative is Firebase, which requires a credit card."

"Supabase Vector rapidly increases the speed and efficiency with which I search through a database, helping with my data analysis tasks."

"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."

"Supabase Vector positively impacts my organization by reducing the cost of the LLMs."

"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 has positively impacted our organization as it is very convenient since our business databases are already hosted in Supabase, making integration easy."

"We completed what we initially estimated as a fifteen-day job in just three days, thanks to the Supabase dashboards and triggers."

"Supabase Vector has made my work a lot easier, especially since we already use PostgreSQL instances on Supabase for our relational database."

More Supabase pros

"Vespa is very good and it improves our product, and we got more clients."

"The best feature to me is the LTR feature, the ranking feature to be specific."

"While conducting A/B testing, Vespa seemed to be performing slightly better than Elasticsearch, especially in search relevancy within live production systems, and its performance was decent."

Cons

"I think there are still many Postgres features that can be developed further by the Supabase team."

"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."

"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 notice that the schema visualizer can be improved. Additionally, the internal AI assistant powered by GPT can also be improved."

"Adapting to Supabase Vector was relatively smooth, but there was definitely a moderate learning curve at the start."

"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."

"I think the support system can be better because after Supabase Vector stopped working in India, there is no support."

More Supabase cons

"The integration is actually a pain."

"Vespa has a considerable learning curve, making it challenging for most people to get into, and it is also expensive, which can deter startups or those with smaller budgets from using it."

"We want Vespa to implement some UI features so that we can visualize how our data goes and what embeddings it stores."

Pricing and Cost Advice

"The solution's cost is reasonable compared to other solutions."
