Security, observability and control.

Key security, DeviceCheck and cert-pinning.

AIProxy uses a combination of split key encryption, DeviceCheck and certificate pinning to prevent your key and endpoint from being stolen or abused.

Device Check

Monitor usage on our dashboard.

Our dashboard helps you keep an eye on your usage and get a deeper understanding of how users are interacting with AI in your app.

Usage metrics

Model overrides and rate limits.

Want to change your API calls from gpt-3.5-turbo to gpt-4o? No problem! You can change models and rate limits right from the dashboard without updating your app.

Option to switch models

Test API calls with live console.

Use the live console to test your OpenAI calls from your app. Find errors and get a better understanding of performance.

Live console

Notifications to keep you alert.

Get alerts when there's suspicious activity so you can take quick action. We'll keep you informed so that you can stay protected.

Alert notifications

Built to scale.

Built on AWS, our service horizontally scales to meet demands. You can be confident that your proxy will continue to run no matter what.

What customers are saying

Juanjo Valiño
"I see developers on Twitter every day struggling with how to secure their API keys. AIProxy makes it simple, so you no longer have to waste time overthinking a backend."
Hidde van der Ploeg
"AIProxy lets us enable pro users to use AI without using their own OpenAI key. This creates a smoother user experience that aligns with our product."
James Rochabrun
"AIProxy is an amazing contribution to the @OpenAI Swift library, thanks @louzell_ and @toddham for the great job! Open source ❤️."
Sam McGarry
"The set up was a breeze. What could have been a confusing multi-step process felt simple. I was able to get back to building immediately, while knowing my API key was safe."
Tirupati Balan
Amigo Finance
"AIProxy has significantly improved our backend operations at Amigo AI, ensuring our GPT key and all OpenAI requests are securely managed. This security gives us peace of mind and lets us focus on delivering excellent financial management AI. The founders have been incredibly supportive and responsive throughout. We're very pleased with their service."
Luca Lupo
"I thought I was safe as IIRC is small but that didn't matter; somehow they targeted my app and were able to spoof the API key by looking at network traffic (I was sending it over a Firebase remote config). I then decided to migrate to AI Proxy, it took literally 10 minutes and the new API key has been safe ever since."
"With AIProxy you just need to know Swift and SwiftUI, no need to learn other languages or frameworks. Additionally, users will benefit as we can eliminate the need to authenticate them. Perfect for developers and users."
Shihab Mehboob
"I’ve been using AI Proxy for the past few months and have been loving the tool. It does exactly what it says on the tin, and without any complications. I appreciate the simplicity and great customer support that I’ve received. Any questions I had have been answered immediately, and any suggestions I’ve made have been added with lightning fast speed."

No, we don't actually store any customer OpenAI keys. Instead, we encrypt your key and store one part of that encrypted result in our database. On its own, this message can't be reversed into your secret key. The other part of the encrypted message is sent up with requests from your app. When the two pieces are married, we derive your secret key and fulfill the request to OpenAI.

The key we provide you is useless on its own and can be hardcoded in your client. When you add an OpenAI key in our dashboard we don't store it on our backend. We encrypt your key and store only half, and give you the other half which you use in your client. We combine these two pieces and decrypt when a request gets made.

We have multiple mechanisms in place to restrict endpoint abuse:
1. Your AIProxy project comes with proxy rules that you configure. You can enable only endpoints that your app depends on in the proxy rules section. For example, if your app depends on /v1/chat/completions, then you would permit the proxying of requests to that endpoint and block all others. This makes your enpdoint less desireable to attackers.

2. We use Apple's DeviceCheck service to ensure that requests to AIProxy originated from your app running on legitimate Apple hardware.

3. We guarantee that DeviceCheck tokens are only used once, which prevents an attacker from replaying a token that they sniffed from the network.

The proxy is deployed on AWS Lambda, meaning we can effortlessly scale horizontally behind a load balancer.

Upon configuring your project in the developer dashboard, you'll receive initialization code to drop into the SwiftOpenAI client. Alternatively, you can use a bootstrap product like WrapFast.
