Can your developers still read your raw .env file?

// Before: keys exposed in your code
const response = await fetch('https://api.stripe.com/v1/charges', {
  headers: {
    'Authorization': `Bearer ${process.env.STRIPE_KEY}`
  }
});

// After: one line change, keys are gone
const response = await fetch('https://proxy.knoxcall.com/stripe/v1/charges', {
  headers: {
    'X-Knox-Client': 'your-client-id'
  }
});
