Overview
Netlify AI Gateway is a fully managed API gateway that simplifies building AI-powered applications by eliminating infrastructure complexity around authentication, billing, and credential management. Developers gain instant access to models from OpenAI, Anthropic, and Google Gemini without creating separate provider accounts or managing API keys. The gateway securely routes requests to AI providers using server-side credentials, applies automatic rate limiting to control costs, and provides unified usage analytics across all AI providers. Now generally available as of December 2025, AI Gateway enables developers to move rapidly from experimentation to production-ready AI features.
Key Features
- Unified API for Multiple Providers: Single endpoint for OpenAI (GPT-5 Pro, GPT-4o, GPT-4o mini), Anthropic (Claude 3.5 Sonnet, Claude 3 Opus, Claude 3 Haiku), and Google Gemini with instant model switching
- Automatic Credential Management: Netlify injects provider credentials server-side, eliminating manual API key setup and exposing sensitive authentication data
- Built-in Rate Limiting: Per-plan token-per-minute (TPM) limits prevent runaway costs with configurable alerts and automatic throttling
- Usage Analytics and Observability: Unified dashboard showing token consumption, cost tracking, error rates, and model usage patterns across all providers
- Caching Layer: Automatic request caching reduces redundant calls to AI providers and decreases overall token consumption
- A/B Testing Capabilities: Route requests to different models or providers based on user segments to benchmark performance and optimize costs
- Function-Level Integration: Works seamlessly with Netlify Functions and Deno-based edge functions with official SDK support
- Team Collaboration: Centralized credential and billing management for multi-team deployments with role-based access controls
How It Works
Developers deploy code to Netlify Functions or Edge Functions that call the AI Gateway endpoint instead of provider APIs directly. The gateway validates requests against configured rate limits and caching rules. For cache misses, it routes requests to the specified provider using stored credentials, then returns responses while logging usage metrics. All authentication happens server-side, preventing credential exposure to client-side code. Usage is tracked per function, per user, and in aggregate, with real-time dashboards and historical analytics available in the Netlify UI. Teams can configure per-application rate limits, failover strategies, and A/B testing rules through simple configuration files or the dashboard.
Use Cases
- Rapid AI Prototyping: Build and deploy AI features in minutes without setting up provider accounts, managing API keys, or configuring billing
- Multi-Model Experimentation: Quickly compare outputs from different models (GPT-4o vs Claude vs Gemini) by changing a configuration parameter
- Cost Control: Rate limits prevent overspending during development and scaling; unified analytics reveal which functions consume most tokens
- Team AI Development: Centralized credential and billing management enables multiple developers to build AI features without individual provider accounts
- Production AI Features: Scale AI capabilities with enterprise-grade observability, failover, and cost management built in
Pros \& Cons
Advantages
- Simplifies Security: Eliminates exposing API keys in environment variables; server-side credential injection reduces attack surface
- Easy Setup: Zero provider account setup required; start using AI models immediately after deploying to Netlify
- Cost Control: Built-in rate limiting and \$5,000/month default usage budget included with AI Gateway prevent unexpected bills
- Unified Billing: Single invoice for all AI provider usage instead of managing separate accounts and bills
- Integrated Observability: Built-in analytics dashboard eliminates need for separate monitoring tools
- No Vendor Lock-in: Bring your own API keys at any time if you prefer direct provider connections
Disadvantages
- Rate Limits Apply Per Plan: Free and lower-tier plans have TPM restrictions; higher tiers required for production workloads
- Adds Proxy Layer: All requests route through Netlify infrastructure before reaching AI providers, adding latency (typically <100ms)
- Limited Advanced Features: Lacks prompt management, A/B testing configuration flexibility, and advanced provider-specific options
- Netlify Platform Dependency: Only works within Netlify ecosystem; developers using other hosting require different solutions
- Model Latency: Proxy adds minimal but measurable latency compared to direct provider connections
How Does It Compare?

Final Thoughts
Netlify AI Gateway successfully achieves its stated goal of removing friction from building AI features within the Netlify ecosystem. The automatic credential management, unified rate limiting, and integrated analytics dramatically accelerate development velocity for teams building on Netlify. The platform’s general availability status and rapid feature additions (GPT-5 Pro support within days of release) demonstrate Netlify’s commitment to staying current with model releases.
For developers building applications exclusively on Netlify, AI Gateway represents the easiest path from experimentation to production AI features. The included \$5,000/month usage budget and transparent pricing structure remove financial uncertainty for teams ramping up AI usage. The ability to switch models via configuration without code changes enables rapid experimentation and optimization.
However, the Netlify platform dependency and proxy latency may not suit all use cases. Teams working across multiple hosting providers or requiring ultra-low latency inference should evaluate alternatives like Cloudflare AI Gateway or direct provider connections. Similarly, teams needing advanced routing logic and team collaboration features might justify Portkey’s platform subscription despite higher costs.
For startup teams, agencies, and individual developers building on Netlify, AI Gateway offers exceptional value and developer experience. The platform removes entire categories of work (account creation, API key management, cost monitoring) that slow development, allowing teams to focus on building differentiated features rather than infrastructure plumbing.
