# Introduction

> The simplicity of webhooks meets the durability of event streaming.

# eldrStream

EldrStream is a managed event delivery platform that receives events from your application and reliably dispatches them to your configured webhook endpoints. It handles encryption, retry logic, ordering guarantees, failure recovery, and real-time observability — so you can focus on building your product.

## What eldrStream does

1. **Ingest** — Your application sends events to the EldrStream Edge endpoint using your API key.
2. **Secure** — Every event payload is encrypted at rest and signed before delivery.
3. **Deliver** — EldrStream routes each event to your registered webhook URL(s), automatically retrying transient failures with exponential backoff.
4. **Observe** — Query your event history, filter by delivery state, and replay events at any time from the console or API.
