Introduction

SeeStack is a full-stack observability platform that gives you visibility into errors, logs, HTTP traffic, user sessions, cron jobs, and feature flags — all from a single SDK. Initialize once at application startup and the SDK handles the rest: buffering, batching, retrying, and delivering telemetry to your SeeStack instance.

All SDK calls are async and fail-safe. The SDK will never crash your application or block your main thread.
