Uptime

n1n transformed our workflow. Switching between GPT-5, Claude 4.5, and open-source models with one config line is game-changing. We used to spend days refactoring adapters; now it takes seconds.

Latency reduction is tangible. Serving users in SEA and Europe, n1n's edge caching cut our TTFT by 40%. It's not just an API wrapper; it's a genuine infrastructure upgrade for our global user base.

Reliability is key. We've been running on n1n for six months with impeccable uptime. The automatic fallback mechanism saved us twice during upstream outages. Our users never noticed a thing.

Budget controls are a lifesaver. Managing API keys across 15 developers was a nightmare. With n1n, I set hard limits per project. It's saved us thousands in accidental overruns and surprise bills.

Docs are top-tier. Clear examples, typed SDKs, and a responsive community. Integrating it into our Next.js stack took less than an hour. The developer experience is unmatched in this space.

Model-agnostic is the future. We started with OpenAI, switched to Anthropic for reasoning, and now use DeepSeek for coding. All without changing core logic. It gives us true vendor independence.

The unified billing simplified our accounting significantly. Instead of managing invoices from five different AI providers, we get one clear statement. It's a small detail that saves huge administrative headaches.

I built a prototype in a weekend that would have taken weeks. The pre-built integrations and standardized error handling meant I could focus on product logic, not API quirks. Highly recommended.

Security compliance was our biggest hurdle. n1n's SOC2 readiness and data privacy features ticked all the boxes for our enterprise clients. It allowed us to go to market months earlier than planned.

Our Mission

Why We Built n1n

We believe the future of software is intelligent. We built n1n to make that future accessible, joyful, and simple for everyone.

A Universe of Possibility

The world of AI is exploding with creativity. Every day, amazing new models appear—some are poets, some are coders, some are artists.

We looked at this colorful chaos and saw potential. What if you could play with all of them, without boundaries?

The Complexity Puzzle

But connecting these dots was harder than it looked. Tangled wires, mismatched plugs, and endless manuals slowed us down.

We realized that builders shouldn't spend their time fighting with plumbing. You should be dreaming up the next big thing.

Harmony at Last

So we created n1n. Think of it as a universal translator for intelligence. It turns the noise into a symphony.

Now, you have one simple API Key to unlock the entire universe of LLM Models. It’s a powerful API Gateway, it’s effortless, and honestly? It’s pretty fun.
