## About Cascadehook

Cascadehook is a service for sending webhook events from your product to your customers' endpoints without building the delivery infrastructure yourself. Your application publishes an event through an API call with a project API key, and Cascadehook delivers it to every endpoint subscribed to that event type.

Each outgoing webhook is signed with HMAC, so the receiving system can verify that the request came from you before it parses the body. When an endpoint responds with a temporary failure, such as a timeout or a retryable error, Cascadehook reschedules the delivery automatically with backoff and jitter, and it respects Retry-After headers when they are sent. Every attempt is recorded with its status and duration, so you can inspect what happened and replay a delivery once the endpoint is ready.

The product suits development teams that need to notify customers or internal systems of events such as invoice payments, and that would rather not maintain their own queues, retry logic, signing and delivery logs. An Idempotency-Key header can be supplied with each event request, and the site includes a quickstart and a receiver guide for connecting an endpoint.

## About SignUpSpark

SignUpSpark is an online signup sheet tool. An organizer sets up an event, adds the slots they need, such as dishes to bring, volunteer shifts or snacks, and shares a single link by text, email or post. Guests claim a slot with just a name and email, without creating an account or password. The organizer gets a real-time dashboard showing who is bringing what, who has paid and who is on the waitlist, and can export signups to CSV at any time.

The product sends 24-hour and 1-hour reminders to attendees automatically, and the free plan includes one active event with up to 100 signups. Pro adds unlimited events and signups, a Create With AI event builder that turns a plain-English description into a signup page, collection of payments through Venmo or PayPal, and custom branding. Teams adds five organizer seats, organization branding and removal of SignUpSpark branding from event pages.

It is aimed at room parents, team parents, volunteer coordinators and people running school events, sports teams, nonprofits and community groups who need a simple way to organize who brings or does what.
