The AI gateway built
for software development agencies
Access 200+ AI models through one API, with intelligent routing, caching, fallbacks, observability, and cost controls built in. For client applications, internal tools, and everything your team builds next.
Chosen by leading engineering teams
All your models,
all your costs, one view
AI Gateway
Give every client project access to 200+ AI models through one API. Switch between models without touching your code.
Observability
Track requests, tokens, costs, latency, and errors across projects. Drill down by client, team, user, API key, or model.
Cost attribution
Attribute spend to the project or API key that generated it. Bill each client accurately so you know exactly where every dollar goes.
Cost optimization
Route requests to the most efficient model, cache repeated prompts, and see which projects and models are driving spend.
Keep production workloads reliable
Automatic fallbacks and 99.99% uptime keep client applications running – even when a provider goes offline.
Governance and control
Control who can use which models, set budgets and usage limits, and manage permissions across your organization.
One gateway behind
every client you serve
Build AI products for clients
Connect client applications to 200+ models with routing, caching, fallbacks, and observability built in. Skip building the same infrastructure project by project.Add AI to existing products
Integrate models into client applications you're already maintaining. Provider-specific logic stays in the gateway, not the codebase.Run AI in production
Manage model availability, fallbacks, performance, usage, and costs across every application you operate for clients.Use AI across your own teams
Centralize model access and see AI usage across engineering, internal tools, coding workflows, and experiments.Keep your data secure with a European AI gateway
No training on your data
Your data stays yours. It will never be used to train AI models unless you explicitly allow it.Zero data retention
Enable Zero Data Retention (ZDR) for supported models to ensure prompts and responses aren't stored by the provider.SSO and access controls
Secured access with SSO and RBAC to protect sensitive information.Hosted in Europe
The nexos.ai platform and most of our available models are hosted in Europe. You can freely decide which LLM to use based on your preferences and compliance requirements.Fully certified and secure
SOC 2 Type 2, ISO 27001 and ISO 42001-certified. Fully compliant with the GDPR.
