Install
Add the SDK to your Node or Python project and drop in a single API key. That's the entire setup.

Everything you need to schedule a webhook — and nothing you don't
Three lines to integrate, proof over promises, and a live playground so you can watch a real webhook fire before you sign up.
How it works
Install, schedule, and fire on time
Three steps is all it takes. The rest — queuing, retries, signing, and SSRF protection — is handled for you.
Schedule
Pass the fire time and payload. Your data is encrypted with AES-256 the moment it is stored.
sendit.schedule({ fireAt, payload })Fire on time
At the scheduled moment the webhook is sent with an HMAC signature, fired slightly early to offset round-trip latency.

Proof over promises
Code and numbers in place of adjectives — a small, dependable tool built by a developer, for developers.
Developer experience
A three-line developer experience
No broker, no consumer, no ports. Install the SDK, call schedule() once, and scheduled delivery simply works.
No Docker, IAM, or port setup — zero
Predictable cost, no surprises
Even when traffic spikes, your invoice stays the same.
$19/ mo flat
vs flat plans from $180 / mo
Visual control at your fingertips
Search schedules, edit or cancel with a click. Every delivery result in one dashboard.

Spike-safe by default
Requests are queued and smoothed, then delivered in order — never dropped.
Second-level + Early Firing
We fire slightly early to offset round-trip latency.
