We Put Localhost on the Internet and Watched Who Turned Up
A Cloudflare quick tunnel gives you a public URL for a port on your laptop in one command and no account. We ran one in front of a server that logs everything and answers nothing, to find out how long it takes the internet to find you, and what the thing actually costs.

The design that handles that without duplicates: an outbox keyed by event, user and channel, preferences evaluated at send time, digest windows, and provider feedback wired back in.

Stop Building Webhook Retries Yourself
We pointed a webhook sender at a receiver built to fail the common ways production fails: outages, 429s, timeouts, dead endpoints, bad signatures. Then we watched the retries, the schedule, the signature checks, and the replay happen without writing any of it. Here is the run, with the code and the attempt logs.
From DNS to Delivery: Building Transactional Email with SMTPFast
Connect a domain, send a FastAPI receipt through SMTPFast, trace delivery beyond the 200 response, and verify signed webhooks end to end.
What It Actually Takes to Deliver a Webhook in Production
