Common Questions

How is Serla different from Mixpanel?

Serla offers the same core analytics primitives (funnels, cohorts, retention) but removes the implementation complexity. We don't require heavy SDKs—just a simple API endpoint.

Do I need to use an SDK?

No. We offer optional single-file SDKs (TypeScript, JavaScript, Python) for convenience, but you can use standard fetch requests from any language. Your choice.

Can I export my data?

Yes. Data portability is a core value. You can export raw event data to CSV or JSON at any time via the API.

Is my data secure?

All data is encrypted in transit (TLS 1.3) and at rest (AES-256). We run on SOC 2 Type II compliant infrastructure.
