Question 1

What is the cheapest way to add LLM Gateway functionality?

Accepted Answer

LiteLLM and Cloudflare AI Gateway both offer free tiers with no per-request gateway fees, making them the lowest-cost entry points. LiteLLM is open-source and self-hosted, so you pay only for the LLM providers themselves, while Cloudflare AI Gateway is free for small projects if you are already using Cloudflare's services. Both require you to pay LLM providers separately for actual model usage.

Question 2

Can I self-host an LLM Gateway alternative?

Accepted Answer

Yes. LiteLLM is open-source and designed for self-hosting, giving you full control over deployment and data. Kong AI Gateway also supports self-hosted deployment for teams with existing Kong infrastructure. Self-hosted options eliminate vendor lock-in and per-request gateway fees but require you to manage infrastructure, updates, and operational support yourself.

Question 3

Which alternative is best for observability and cost tracking?

Accepted Answer

Portkey is purpose-built for LLM observability, offering request-level tracing, user tracking, cost forecasting, and real-time alerts as core features. Its observability capabilities are comprehensive and designed specifically for LLM workloads rather than generic API monitoring. If you need detailed visibility into LLM spending and performance across multiple models and providers, Portkey is the strongest choice among the alternatives.

Question 4

Is Cloudflare AI Gateway better than LLM Gateway for edge performance?

Accepted Answer

Cloudflare AI Gateway runs on Cloudflare's global edge network, which can provide lower latency and built-in caching if you are already using Cloudflare. LLM Gateway is a general-purpose routing layer without edge deployment. If edge performance and zero additional infrastructure are priorities and you use Cloudflare, Cloudflare AI Gateway is the better fit; otherwise, the difference depends on your specific deployment and latency requirements.

Question 5

Which alternative works best for multi-team governance and enterprise use?

Accepted Answer

Kong AI Gateway is positioned for enterprise teams and API management organizations that need standardized governance, quotas, and policy enforcement across multiple teams. It builds on Kong's mature API gateway infrastructure and supports enterprise-grade features like role-based access control and federated governance. Portkey also supports multi-team setups but is typically better suited for smaller teams moving into early production rather than large enterprises.

Question 6

Can these alternatives handle the same core job as LLM Gateway?

Accepted Answer

Yes. All listed alternatives support multi-provider LLM routing through a unified API interface, which is the core function of LLM Gateway. Most offer OpenAI-compatible APIs for easy integration. The differences lie in deployment model, observability depth, governance features, and integration with existing infrastructure rather than fundamental routing capability. Your choice should depend on which secondary features and deployment constraints matter most to your team.

Question 7

How do I migrate from LLM Gateway to an alternative?

Accepted Answer

Most alternatives use OpenAI-compatible APIs, so migration typically involves changing your API endpoint URL and updating authentication credentials. Export any routing rules, model configurations, or usage data from LLM Gateway before switching. Test the new gateway in a staging environment to verify that model responses and latency meet your requirements. If you have custom integrations or observability dashboards, plan time to rebuild or reconfigure them in the new platform.

Question 8

Which alternative is best for solo developers or small teams?

Accepted Answer

LiteLLM and Cloudflare AI Gateway are both strong choices for small teams and solo developers. LiteLLM offers simplicity and open-source flexibility with no per-request fees, while Cloudflare AI Gateway provides managed convenience if you already use Cloudflare. Portkey is also suitable for small teams moving into early production and offers more built-in observability than the other two, though it is a paid service.
