LLM Gateway Reviews

Our main use case for LLM Gateway is that our company has partnerships with multiple LLM providers including OpenAI, Claude, and Gemini. LLM Gateway acts as an interface between all three providers. I would describe it as a router that functions as middleware between our application and the AI providers so that we do not need to give or share API keys to each team.

Our team calls LLM Gateway from their application, and all the keys and routing configurations are present in LLM Gateway. Its responsibility is to connect with Claude, OpenAI, or Gemini based on the request we receive.

We have an application in which users can ask anything. For example, if a user is asking a general question, we call LLM Gateway and pass the model name as ChatGPT. It internally uses ChatGPT itself. If the question is related to the application we created, it internally uses RAG and goes to Claude. LLM Gateway is responsible for redirecting the request based on context.

LLM Gateway also has an additional feature where if one of the models is unavailable at a time, it automatically redirects the request to another model, so there is no downtime in the application. The automatic failover feature ensures that if one model is not available, LLM Gateway redirects the request to another model.

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.

Regarding improvements, I think the pricing can be more competitive. LLM Gateway takes 5% of the token usage, which feels a bit high. While they do have a free tier, the costs for the enterprise edition are somewhat high. As a new product in the market, it should charge less compared to competitors. However, I think the cost is comparable or slightly higher.

I have been using LLM Gateway for around 1.5 years. It is a new product in the market.

LLM Gateway is stable. It is a new product, but it is heading in the right direction.

Currently, we are using around 20 models, and it works fine. LLM Gateway claims integration with around 200 models, but we have only utilized 20 in our organization so far.

The customer support and documentation for LLM Gateway are pretty good. Although the community is a bit sparse because of its newness, the available support is very effective. I rate the customer support a perfect 10.

I previously used Portkey in a different organization but have not switched from Portkey to LLM Gateway within the same organization.

I usually start with the free tier, which is very good. For the enterprise version, LLM Gateway charges as other products do, but the setup time is quick, under a minute, with no cost for the free tier. After using LLM Gateway, we see that our security risks have reduced. In my organization, we do not only look at ROI; we also consider security threats. Since adopting LLM Gateway, the complexity of our projects has decreased, and the security concerns have lessened. I estimate it has saved us around 20-30% of our time, and around 30% sounds reasonable.

I have not evaluated other options. The setup cost, time, and the free tier availability made LLM Gateway an easy choice for us.

The accuracy of LLM Gateway's output is quite good. If one model is down, it automatically redirects requests to another model, which is a very beneficial feature. My advice for others looking into using LLM Gateway is to start with it. It takes very little time to set up and has a user-friendly dashboard that displays model usage. You can also set thresholds, specifying the number of tokens or costs for each model, which is very convenient. Depending on the product size, since it is new in the market, our usage has been satisfactory. I have given this review a rating of 9 out of 10.

My main use case for LLM Gateway is that as new AI use cases emerge, such as a new internal agent or a customer-facing assistant, teams do not start from scratch; they simply plug into the gateway.

One clear example of how my team has used LLM Gateway for one of those use cases is our internal AI assistant that helps operations and support teams get quick answers about orders, inventory, and internal processes. Every time that assistant makes a call to a language model, the request goes through the gateway, so we automatically capture which model was used, how long it took, how many tokens were consumed, and whether there were any errors. If a provider slows down, we can route traffic to a fallback model without changing application code, which saved us from scrambling during a couple of peak load situations.

LLM Gateway quietly becomes part of the default developer workflow; new AI services start with the gateway by default, which means we do not have to relitigate logging, monitoring, or provider switching every single time. It lowers the friction to experiment but keeps things observable and manageable as we scale.

For us, the best features LLM Gateway offers are centralized observability, multi-provider routing, and resilience. Centralized logs and metrics make debugging and cost tracking far easier. Routing lets us switch or test models without touching application code, and retries plus fallback strategies add resilience when providers experience issues. Additionally, it is valuable having a single place for policy concerns such as rate limits and consistent authentication.

The feature that has had the biggest impact on my day-to-day work is centralized observability; that is the feature we feel every day. When something is off, latency spikes, cost jumps, or a prompt misbehaves, we check one dashboard and trace it. That beats digging through five services' logs, and it also helps during rollouts because we can see real usage and cost almost immediately. Routing and fallbacks matter, but observability saves us time every single week.

The features work best as a bundle. Observability tells you what is happening, routing lets you act on it quickly, and resilience keeps user impact low while you fix root cause. It is that combination that makes it feel like infrastructure you can rely on, rather than a loose set of SDK calls.

LLM Gateway has impacted our organization positively by making us faster and calmer. We are faster because spinning up new AI features does not mean reinventing provider plumbing, and we are calmer because when something goes wrong, we know where to look and we have levers to pull, which reduces fire drills. It also builds confidence to experiment because rollbacks and provider changes feel safer.

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. I also think richer audit trails and policy controls for larger organizations would be valuable to have as we scale.

More prescriptive examples or reference architectures for common patterns such as RAG, agent workflows, and evaluation pipelines would help teams avoid reinventing patterns and speed up onboarding even more.

I have been using LLM Gateway for about one year.

LLM Gateway is stable for us; it has been steady with solid uptime, and there have been no major outages attributable to the gateway. Most issues we have seen have come from upstream model providers, and the retry fallback policies help smooth those. Operationally, it has been low maintenance, which is the point; you do not want the gateway to become something you have to monitor constantly.

LLM Gateway scales well for us so far; we have ramped from a couple of internal tools to multiple production workloads without major re-architecture. Performance has been predictable under higher request volumes, and we have not experienced rate limiting or throughput bottlenecks attributable to the gateway. If anything, the choke points tend to be provider-side or in our application logic, not the gateway itself. As we grow, more predictive performance analytics and proactive alerts would help us stay ahead of spikes rather than just react.

Customer support for LLM Gateway has been responsive and technical; when we had implementation questions early on, responses were quick and specific, not generic replies. Most issues did not require escalations because the documentation covered the basics, but when we did reach out, turnaround was solid. Ongoing, we have not needed much hand-holding, which is a good sign.

We did not previously use a different solution; we did not have a formal gateway before. It was direct SDK integrations in each service, which meant duplicated retry logic, scattered logging, and painful provider comparisons. We considered building a thin in-house layer but chose a dedicated gateway to avoid ongoing maintenance and get observability and routing out of the box. We switched centralized concerns we were solving poorly in ten places into one place we can manage and trust.

I can share specific outcomes or metrics that show the positive impact; we have seen a measurable return, though I would frame these as solid internal estimates rather than formally tracked KPIs. We see roughly thirty to forty percent less development effort on new AI features because teams integrate once with the gateway instead of building custom provider logic each time. Model evaluations are about fifty percent faster since we can switch or compare providers through configuration rather than code changes. On the cost side, centralized observability has helped trim unnecessary LLM spend by around fifteen to twenty percent by surfacing inefficient prompts and duplicate requests. Troubleshooting is also about thirty to forty percent faster because all the signal is 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. The return has come more from developer velocity and operational clarity than from direct license savings.

We have seen a return on investment; I would call these relevant metrics internal estimates more than audited KPIs. We are seeing roughly thirty to forty percent less development effort on new AI features, about fifty percent faster model evaluation cycles, fifteen to twenty percent lower LLM spend from spotting inefficient prompts and shifting to better-fit models, and thirty to forty percent faster troubleshooting thanks to centralized logs. All told, that shows up as maybe a twenty to twenty-five percent productivity lift for engineers working on AI features. We have not reduced headcount because of the gateway, but we have avoided adding operational overhead as AI usage grew, which is where the return feels strongest.

My experience with pricing, setup costs, and licensing for LLM Gateway is that it is reasonable and predictable for us. The setup was light, mostly involving integration and configuration rather than heavy infrastructure work. Pricing felt aligned with infrastructure value and more like a shared platform cost than per-seat overhead. The real ROI shows up in reduced engineering time and consolidation of tooling, rather than deep license arbitrage.

I evaluated other options before choosing LLM Gateway; I looked at a couple of other commercial gateways and debated rolling our own. Direct integrations were the baseline but became hard to manage as use cases multiplied. Building in-house looked flexible, but it would have pulled engineers into long-term platform maintenance. I chose this gateway for the balance of multi-provider support, centralized observability, and ease of integration with our existing AWS stack. It let us standardize quickly without becoming a platform team, which kept our focus on shipping product features rather than running gateway infrastructure.

My advice for others looking into using LLM Gateway is to start with a clear use case and onboard one or two services first. It is important to get logging, cost views, and fallbacks wired in early, then bake it into your default service template so teams do not bypass it. Do not over-rotate on exotic routing on day one; establish visibility first and treat it as an enabling layer, not a silver bullet. Keep prompt quality, evaluations, and data governance as first-class concerns alongside the gateway, not after.

If you are scaling AI features across teams, centralization pays off. Start simple, instrument early, and allow the gateway to reduce toil while you focus on product value. I would rate my overall experience with LLM Gateway as an eight out of ten.

I use LLM Gateway primarily for key tracking. Since we have agents, I need to know which agent is using which key and how much cost it is consuming per each message. LLM Gateway helps me manage the keys, store the keys, and save them, and it also provides an analytical dashboard with spend logs showing how much each agent is costing, what model it is using, and everything related to it.

What I appreciate most about LLM Gateway is that there is no need to maintain multiple keys. It provides one virtual key that I can use to access everything. The spend logs feature has been particularly helpful for my organization to understand the total spending on AI keys from OpenAI, Anthropic, and similar providers. I could also build a comprehensive dashboard to demonstrate to my management.

A better interface and improved logs would enhance my experience with LLM Gateway. A more user-friendly interface would be beneficial.

The logs could be improved by providing better error messages. When issues arise, I usually check the logs to identify what went wrong. Currently, this can be difficult, but better error messages would make it easier for me to debug problems.

I have been using LLM Gateway for the past one and a half years in my career.

Regarding stability, I have observed that it gets stuck a couple of times, which required me to restart it. For a couple of minutes it would get stuck and cause issues. However, in recent days, the stability has improved significantly. When I first started using it one and a half years ago, it used to be somewhat laggy and would get stuck intermittently, but now it performs well.

Regarding scalability, I have not faced any issues. My application has a very small number of users, so LLM Gateway works well for my current needs. I may potentially face scalability issues in the future, but I am not aware of any concerns currently because my application and user base are minimal.

I have not contacted any technical support or customer support from LLM Gateway.

I have not used anything similar to LLM Gateway before. When I decided to use LLM Gateway, I explored a couple of other options, but I proceeded with this one because I felt it was the best choice among all the alternatives and it was less expensive.

The initial deployment was straightforward. I was able to set it up within a few days and begin using it.

LLM Gateway does not require any maintenance on my end.

I would advise new users that LLM Gateway provides better traceability of the models being used while maintaining security. It is secure, cost-efficient, and offers superior traceability. I would rate my overall experience with this product an 8 out of 10.

My main use case for LLM Gateway is building an agentic system, a harness wherein we can build multiple use cases that will be supported mainly for PDLC and SDLC automation.

Whenever we want to use LLM Gateway for PDLC or SDLC automation, we want to create spec-to-code or code-to-spec, and we want to convert ideas into specifications.

Whenever we want to create any documentation or any features or epics from converting from code to spec-to-code using LLM Gateway, we need to call multiple LLMs, and we want some intermediate gateway wherein it will handle our authentication, authorization, as well as the cost optimizations can be seen. For that purpose, we have used LLM Gateway. Some of the use cases need multi-modal calls wherein we can use multiple models at the same time, so LLM Gateway is a valuable gateway to work with.

The best features LLM Gateway offers include cost optimization, multi-modal support, and authentication and authorization all in one place. The way the API gateway handles requests is a major advantage.

The integration capabilities are very simple, and it can be integrated with any open-source tools. We were using Temporal and OpenHands, and integration was quite straightforward. You can create an instance of LLM Gateway on a local machine as well, which is very helpful for developers to work with it, and you can have analytics drawn with the activities.

LLM Gateway has positively impacted my organization because costs have increased with AI, and as a Solution Architect, I need to consider the cost optimization part. I need to understand how many tokens are being consumed and where we are heading. LLM Gateway gives us analytics on the cost optimization and cost expense, so as an architect, we can understand and perform our cost optimization part based on that information.

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.

I have been using LLM Gateway for the last eight months, and we are using it for one of our AI-led frameworks.

The advice I can give to others looking into using LLM Gateway is that it is very simple to use, but at the same time, you need to be very sure while creating the API keys that you are not sharing these API keys with any external applications. I find this process quite interesting, fast, and responsive. I rated this review a seven out of ten.
