PavithrarajShetty - PeerSpot reviewer
Offers simplicity and is cheaply priced
I haven't gone through the scalability aspect since I was using MySQL Server. I haven't worked to a high level in PostgreSQL, but with MySQL Server, I have managed clustering and partitioning. I think I haven't put much focus on PostgreSQL, so I am not sure how it behaves or how it works.
Kaustubh Sule - PeerSpot reviewer
Easy to use, and there is no need to get involved in any tedious deployment process
If you are a business building a social media app, there will be thousands of users for every such app. Each user will have a post or something. When multiple users try to hit the like button on your post or try to comment on your post, each of them would be an API request, and Supabase Vector does not charge for them like. The API requests are kind of unlimited. If you compare Supabase Vector to any of the other services like Firebase, AWS, or Azure, all the tools charge per request. From a scalability standpoint, if you are a small-scale startup and you have around 1,00,000 or 2,00,000 users, then Supabase Vector is a perfect choice for you. I have never heard about any scalability issues in the product. Scalability-wise, I rate the solution a ten of ten.

Quotes from Members

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

Pros

"The product is quite flexible."
"This is an open-source solution, operates at a high speed, and supports more than one SQL language."
"Postgres has some functions called JSONB aggregators or other aggregators, which are quite useful."
"We managed to reduce the storage space needed to 10% of the original size, without affecting data integrity, and we significantly improved the performance."
"The solution provides complete support in terms of the SQL dialect and behaves nicely when it comes to transactions."
"It is very scalable and comes with a bonus: no licensing issues as you scale with your databases."
"Scalable, stable, and easy to manage database system, with a straightforward installation."
"The system can perform faster analysis by providing it with a lot of memory. Speed is crucial for analytics. Currently, the main reason we haven't adopted Elasticsearch is that we lack the necessary expertise to manage it."
"The tool is easy to use."
"Supabase enables us to lower the skill floor while keeping the ceiling high."
"Supabase enables us to lower the skill floor while keeping the ceiling high."
"The platform's role-level security feature is quite effective for spatial data management."
 

Cons

"The scalability is limited."
"The search option is not very good."
"PostgreSQL’s performance could be improved."
"There are several features I would like to improve that aren't working as expected. It's likely that the latest version is doing something that was missed in the previous versions. For example, the output parameters — the stored procedures — is something new in PostgreSQL that Firebird has already had for a long time."
"PostgreSQL is a stable system, but from a security point of view, it still needs improvement."
"It could be more secure."
"The performance of PostgreSQL could improve."
"The user interface could be a bit better."
"I think there are still many Postgres features that can be developed further by the Supabase team."
"The support for React Native CLI is an area with certain shortcomings where improvements are required."
"I think there are still many Postgres features that can be developed further by the Supabase team."
"One area for the solution improvement is the inclusion of more sample code in various programming languages, particularly PHP."
 

Pricing and Cost Advice

"It is also open-source so it is free."
"The community version of Postgre is basically free."
"The solution requires a license."
"It is free, but if you need support, you can go for the commercial version called EnterpriseDB. They provide paid support, and they can even do hosting for you if you want standby and support."
"It is open source. There is no licensing."
"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."
"This solution can offer a cheaper choice for customers since it is open-source."
"It is free. There is no license on it."
"The solution's cost is reasonable compared to other solutions."
"As per the product's regular pricing plans, the tools are available to users for 20 to 25 USD per month."
