Engineering & SDK deep-dives

How Pug is built: the SDKs, event delivery, and the design decisions behind them. For concept guides and benchmarks, see Learn.

Inside the Pug Web SDK

Autocapture, identity, consent, and reliable delivery: the developer story end to end.

Batching, a durable queue, sendBeacon on unload, and permanent-vs-transient retry classification.

How standard, typed event names keep your data clean, portable, and useful.

SDKs, autocapture, a typed API, and self-hosting, analytics built for engineers.

The HMAC construction, why deletion beats rotation, and the type that caught a silent bug.

Pug ships Web, Flutter, and Node SDKs over a typed, reliable pipeline. Self-host under AGPL-3.0, or use the free cloud beta.
