Advanced Open Source Vector Database

  • November 21, 2023
  • Review verified by G2

What do you like best about the product?
Setting up an AI client is a complex task. Weaviate makes it possible to try different LLMs combined with hybrid search. This way we get the best of both worlds. We can make inferences based on more traditional search and help the model churn out better results.

Weaviate can be run locally, on-premise or in the cloud. This is really useful for a large number of use-cases. It also provides a clear pathway in case we want to move away from Weaviate Cloud.
What do you dislike about the product?
So far our greatest challenge has been to create a chat like interface with Weaviate. I am sure it's possible but there are no official guides around it. Maybe something on the lines of Assistants API provided by OpenAI would be really useful.
What problems is the product solving and how is that benefiting you?
We have a large corpus of ancient Hindu scriptures. Weaviate helps us to 'see-through' this data and find interesting results, which were simply not possible before.

Out of the box solution of Vector Databases

  • November 21, 2023
  • Review verified by G2

What do you like best about the product?
I appreciate Weaviate's efficiency as a Vector Database, offering seamless integration with LLM models. Its fast computation, coupled with the capabilities for semantic search and RAGs, is admirable. Moreover, its out-of-the-box computing service is not only efficient but also reasonably priced, making it an excellent choice for various applications. It's encouraging to see its continuous development and the growing, supportive community that accompanies it, with a very competent support team.
What do you dislike about the product?
A challenge of using Weaviate is its steep learning curve, especially for those new to the field, requiring a fair amount of technical programming skills to fully utilize its features. Once you reach it, the possibilities are endless!
What problems is the product solving and how is that benefiting you?
Weaviate addresses the need for efficient data management and retrieval in large-scale applications. By utilizing vector databases, it enables rapid, semantic-based search and integrates smoothly with large language models, enhancing data interaction capabilities. This has been immensely beneficial for me in terms of time efficiency and accuracy in data handling, particularly in complex queries where context and nuance are crucial.

Great vector database

  • November 20, 2023
  • Review verified by G2

What do you like best about the product?
It's performant, easy to use, and has lots of great features. It's also a huge plus that it has cloud hosting to get started but is also open source and can be self-hosted. The cloud hosting was easy to set up and integrate with and includes various handy tools like the ability to run GraphQL queries against the data directly from the cloud console. Docs are also excellent, and aside from one issue it has been very robust and reliable.
What do you dislike about the product?
It definitely feels like a young product (which it is), especially the cloud hosting which feels a little barebones. We were also affected by one substantial bug which resulted in broken keyword search (which admittedly is a secondary feature for most Weaviate users). On the plus side, I had some fairly technical questions about how to recover from the bug and received excellent support through Slack.
What problems is the product solving and how is that benefiting you?
We use Weaviate as the database for a RAG/content generation app.

Weaviate Cloud Services is the best vector store option for both novices and advanced users.

  • November 20, 2023
  • Review verified by G2

What do you like best about the product?
As a novice only a few short months ago, I needed a way to impement embeddings which was easy and relatively inexpensive. WCS came through on both of those for me. In addition, as I began to gain more experience, I was able to appreciate more the vast array of embed and retrieval options WCS had to offer. Now, as a grizzled veteran now deploying my 3rd RAG system, I am extremely happy with the decision I made early on to go with WCS. Integrating into my code as very easy. Their support is great and timely, and they appear to spend a good amount of effort continuously improving an already superior system. In RAG, your answers are only ever going to be as good as the documents your model is given to analyze, and I have to say that WCS cosine similarity searches have consistently given me back the best documents for the best answers.
What do you dislike about the product?
I find it necessary to do queries in the WCS dashbord to both design processing code as well as troubleshoot -- and just to see what's in my vector store. The query syntax, while not terribly difficult, isn't the most intuitive. It sometimes takes a few minutes to go back and research how to construct the specific queries you need. It would be helpful if the queries you create are stored in the dashboard. Unfortunately WCS has a bad habit of deletiing them, forcing you to have to go back and re-create them every time you need them. That's actually my biggest pet peeve.
What problems is the product solving and how is that benefiting you?
The biggest problem in RAG is retrieving the documents in your vector store which are most relevant to your prompt. In my experience so far, WCS excels at this. I am working with 3 different datasets which require slightly differenc configurations, and I am able to accomodate them all with WCS. And, again, I have to point out that one of the big hurdles starting out was the cost. The next best competitor was way more expensive than I could afford, especially in the beginning. WCS pricing made this option affordable, thus making it possible to explore and build upon.

Fantastic vector database

  • November 20, 2023
  • Review provided by G2

What do you like best about the product?
It was very easy to get started with weaviate, the pricing is simple and they take care of importing models from huggingface for us and provisioning the db instances so we can concentrate on building our product.

We were able to quickly integrate weaviate with our existing stack using the python libraries.

The documentation is good and we have been impressed by the support we received for our more unusual use cases.

There is an active slack community and we've met several people from the team and they've all been very helpful.

What's more it's all open source so we feel safe choosing Weaviate for a cricical part of our tech stack.
What do you dislike about the product?
The only drawback I can think of is that recall speed can be slow with some queries (e.g. meta filters). I believe this is being worked on though.
What problems is the product solving and how is that benefiting you?
Weaviate makes it possible for us to retrieve embedded products at scale (10s of millions of items).

We moved to Weaviate from Pinecone

  • November 17, 2023
  • Review provided by G2

What do you like best about the product?
We moved to Weaviate because of the ease of integration with our core platform and the performance of indexes and the retrieval latency. And the ease of implementation using Lyzr SDKs has been a hit with enterprise customers.
What do you dislike about the product?
The Weaviate Cloud UI needs an overhaul.
What problems is the product solving and how is that benefiting you?
Index and search vectors faster and at scale.

Ease of use and reliability

  • November 17, 2023
  • Review verified by G2

What do you like best about the product?
Our team has been using Weabiate for about six months. It was very easy to implement a development and production environment and integrate into our AI application. Their customer success team reached out to us to check in but we did not have any issues to address. Weaviate DB is used in our production application daily and has not had any uptime or reliability issues.
What do you dislike about the product?
The billing system is a little bit clunky and it is not easy to see past invoices via the website.
What problems is the product solving and how is that benefiting you?
Weaviate allows us to quicky find and rank related documents that are used to answer/analyze a user's questions.
