AltENV Proxy — API key security

You Haven't Been Breached.
Yet.

Your team has API keys in .env files. AI agents can read them. Every day you wait is another day those keys are exposed.

Why It Keeps Happening

.gitignore was supposed to fix this. It didn't. 23.8 million secrets leaked last year anyway.

AI sandboxing is supposed to fix this. It won't. Every tested AI IDE was exploitable.

The problem isn't behavior — it's architecture. As long as keys live on the machine, they can leak.

Remove the keys from the machine entirely.

AltENV Proxy is a self-hosted API proxy. Your team uses proxy URLs. The real credentials never leave your server. There's nothing to leak, nothing to sandbox, nothing to misconfigure.

# Before (dangerous)
OPENAI_API_KEY=sk-proj-abc123...real-key
STRIPE_SECRET=sk_live_xyz789...real-key

# After (with AltENV Proxy)
OPENAI_API_KEY=unused
OPENAI_BASE_URL=http://altenv.local/p/maple4521
STRIPE_SECRET=unused
STRIPE_BASE_URL=http://altenv.local/p/pine8834

How It Works

Three steps to eliminate API key exposure

1

Deploy AltENV

Run the Docker image on your internal network. Single binary, no dependencies. Under a minute.

2

Add Your API Keys

Use the dashboard to add API keys. Each gets a friendly proxy code like maple4521.

3

Use Proxy URLs

Replace base URLs in your .env. SDKs work normally. Real keys never touch developer machines.

✓

Keys Are Safe

AI agents, git commits, laptop theft — none of it matters. There are no keys to steal.

Works With Your Stack

Point your SDK's base URL to AltENV. Everything else stays the same.

# Your code stays exactly the same from openai import OpenAI client = OpenAI( api_key="unused", # AltENV injects the real key base_url="http://altenv.local/p/maple4521" ) response = client.chat.completions.create( model="gpt-4", messages=[{"role": "user", "content": "Hello!"}] )

Frequently Asked Questions

23.8 million secrets leaked last year. You haven't been caught yet.

Vault manages secrets. AltENV eliminates exposure. Different problem. Vault still puts the secret on the developer's machine at runtime. AltENV never does.

Your API calls fail gracefully. Same as if the API itself was down. No keys are exposed.

Change one line in .env. No code changes. SDKs work normally. If your team can edit an environment variable, they can adopt AltENV.

23.8 million developers thought the same thing.

No. AltENV is closed-source with tamper-resistant binaries. Your security tool shouldn't be forkable.

On YOUR server. AltENV is self-hosted. We never see your keys, your traffic, or your data.

No. AltENV Proxy is a standard reverse proxy — same architecture as nginx or HAProxy. Your app sends a normal HTTP request to AltENV, which injects the API key and forwards it. No certificate manipulation, no traffic interception. No security tool will flag this.

The server stops proxying. No keys are exposed. Renew or export your config.

Yes. Solo: 1. Starter: 3. Growth: 10. Business: unlimited.

Every day you wait is another day your keys are exposed.
