For Serverless Functions
Secrets for serverless, done right
Your Lambda function needs a Stripe key. AWS Secrets Manager charges per API call. Kevorax is $5/month flat — unlimited calls, unlimited functions.
The serverless secrets problem
Serverless is great until you need secrets. Every platform has a different approach:
- •AWS Lambda: Environment variables (baked at deploy) or Secrets Manager (charges per call)
- •Vercel Functions: Environment variables (requires redeploy to update)
- •Cloudflare Workers: Wrangler secrets (CLI overhead) or environment variables
- •Result: Same secret copy-pasted to 5 platforms, rotated manually in 5 places
Works with every serverless platform
AWS Lambda (Node.js)
exports.handler = async (event) => {
const res = await fetch(
'https://app.kevorax.com/api/runtime/secrets/STRIPE_SECRET_KEY',
{ headers: { 'Authorization': `Bearer ${process.env.KEVORAX_TOKEN}` } }
);
const { value: stripeKey } = (await res.json()).data;
// Use stripeKey...
return { statusCode: 200 };
};Cloudflare Workers
export default {
async fetch(request, env) {
const res = await fetch(
'https://app.kevorax.com/api/runtime/secrets/OPENAI_API_KEY',
{ headers: { 'Authorization': `Bearer ${env.KEVORAX_TOKEN}` } }
);
const { value: apiKey } = (await res.json()).data;
// Use apiKey...
return new Response('OK');
}
};Deno Deploy
Deno.serve(async (req) => {
const res = await fetch(
'https://app.kevorax.com/api/runtime/secrets/DATABASE_URL',
{ headers: { 'Authorization': `Bearer ${Deno.env.get('KEVORAX_TOKEN')}` } }
);
const { value: dbUrl } = (await res.json()).data;
// Connect to database...
return new Response('OK');
});Cost comparison
| Solution | Pricing Model | 100K calls/month |
|---|---|---|
| Kevorax | $5/month flat | $5 |
| AWS Secrets Manager | $0.40/secret + $0.05/10K calls | ~$0.90 per secret |
| HashiCorp Vault | $13,823/year minimum | $1,152/month |
| Doppler | $21/user/month | $21+ |
With 10 secrets across 10 Lambda functions, AWS Secrets Manager adds up fast. Kevorax stays $5.
Why serverless developers choose Kevorax
No SDK bloat
Plain HTTP fetch. No AWS SDK, no npm packages. Keep your function bundles small.
Flat pricing
$5/month no matter how many functions or API calls. Budget predictability.
Platform agnostic
Same code works on Lambda, Vercel, Cloudflare, Deno. Move platforms without changing secrets management.
Instant rotation
Update a secret in Kevorax, all functions immediately fetch the new value. No redeployment.
