Centralized AI routing has strengthened data security and simplified multi-model workflows
The best features LLM Gateway offers include multi-provider AI access and the ability to access around 200 plus models available in the market. We just need to pass our key and set up this one, and it can access all the available models. Apart from this, it automatically routes the request based on context if we set it in LLM Gateway. Another feature is the automatic failover functionality where if something goes wrong, it redirects the request to another model. LLM Gateway also provides usage analytics with a dashboard where we can check the current usage of each model and see how many requests are going to each model. It persists data for around 30 days, so we can review usage over the last month. LLM Gateway can be self-hosted as well, which is beneficial for large companies with security concerns. I find multi-provider access and failover to be the most valuable features day-to-day. Multi-provider access integrates all available models, acting as a router between the application and LLM Gateway. If my application is using four different models, I only need to call LLM Gateway, which manages everything. We also do not need to share sensitive API keys, as the developer can directly call LLM Gateway, which handles everything seamlessly. The failover feature automatically redirects requests if something goes wrong in one model, and it is incredibly easy to configure. It does not take more than a minute to set up. One positive impact of LLM Gateway on my organization is reducing security risk. If we give API keys to everyone, they can misuse them outside the organization. However, we no longer share API keys, as users just need to call our LLM Gateway, and the API keys remain secret and contained within our on-premises setup. Security-wise, it has significantly reduced our organization's risk.

Centralized networking has secured multi-cloud data pipelines and improves analytics reliability
VNS3 could improve in terms of ease of setup, as while it is powerful, initial configuration for complex multi-cloud topologies can still feel quite technical and requires strong networking knowledge. Another potential improvement would be to tighten native integration with modern data stack tools; Airflow, dbt, and cloud data warehouses can benefit from more out-of-the-box connectivity templates. Additionally, the user interface and observability experience could be more modern and intuitive, especially for quickly diagnosing network flows without diving deep into logs. A pain point regarding needed improvements is that troubleshooting can still feel quite network engineering heavy. For data teams in my organization, we often want more pipeline-level visibility, such as directly seeing which ETL jobs or data flows are impacted when a tunnel or route changes. I would also appreciate more automation around policy setup, such as having auto-generated secure network templates for common data architectures such as AWS to Snowflake or on-premises to BigQuery, which would significantly reduce setup time.

Quotes from Members

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

Pros

"What I appreciate most about LLM Gateway is that there is no need to maintain multiple keys."
"We have seen a positive return on investment, reducing the time required to integrate new AI models by around 40 to 50 percent, cutting troubleshooting time by about 30 percent through centralized logging and monitoring, and improving service availability with automatic failover, which has reduced operational overhead and allowed the team to focus more on delivering new features rather than maintaining integrations, resulting in a clear ROI."
"Since adopting LLM Gateway, the complexity of our projects has decreased, the security concerns have lessened, and I estimate it has saved us around 20-30% of our time."
"LLM Gateway is a very efficient solution for what it proposes and I believe it is a solid option if you want to use something that is self-hosted and you can customize extensively."
"The best features LLM Gateway offers include cost optimization, multi-modal support, and authentication and authorization all in one place."
"Together, we would estimate a twenty to twenty-five percent lift in engineering productivity on AI work, and from a business angle, new AI capabilities reach production about twenty-five to thirty percent faster because the plumbing is already in place."
"VNS3 has positively impacted my organization by centralizing management and reducing operations overhead in terms of manpower and cost."
"People should try VNS3 as we have not faced any issues with this product and I recommend it to others."
 

Cons

"If LLM Gateway could give us a facility or capability to create our own dashboards depending on our requirements, it would be helpful as an improvement."
"The single sign-on functionality being locked out for the enterprise plan is a significant downside, but it is something that can be worked around since LLM Gateway is an open-source project."
"I see a few areas where LLM Gateway can be improved, including clearer cost guardrails and budget alerts that are more proactive, smoother project and workspace organization as the number of services grows, and more first-class support for prompt versioning and experiment tracking so that product teams can self-serve comparisons more easily."
"Regarding improvements, I think the pricing can be more competitive."
"A better interface and improved logs would enhance my experience with LLM Gateway."
"LLM Gateway is a strong platform, but there are a few areas where it could improve."
"VNS3 could benefit from additional features such as the ability to share files through a pre-signed URL, which would be useful for team members to collaborate."
"VNS3 could improve in terms of ease of setup, as while it is powerful, initial configuration for complex multi-cloud topologies can still feel quite technical and requires strong networking knowledge."
