Our goals

Our goal here is pretty simple: we just want to make it extremely easy to schedule a delayed or recurring job.

You should be able to enqueue a new job in seconds. Turn a schedule on or off with the flick of a switch. Edit the cadence of a schedule without redeploying anything. Persist state between jobs without adding a database.

Webhook events? We got you covered. Idempotency? Heck yeah. Logs? So many logs.

These days, it's trivial to hack together a script and deploy it as an API. With tools like Replit, Vercel, and Fly, you can have something written and deployed in minutes, all for free.

Shouldn't scheduling stuff be just as simple?

Check out some examples

Easy as 1, 2, 3

Just spin up an API endpoint, create a scheduled job, and start monitoring. All in less than 2 minutes.

Step 1: Spin up your API

replit.com/@me/healthcheck

1import express from "express";
2
3const app = express();
4const port = process.env.PORT || 3000;
5
6const notify = async () => {...};
7
8app.get("/api/run", async (req, res) => {
9  const response = await fetch(
10    'https://scheduler.booper.dev/api/ping'
11  );
12
13  if (!response.ok) {
14    await notify("API is down!")
15
16    return res.json({ ok: false });
17  }
18
19  const data = await response.json();
20
21  return res.json({ ok: true, data });
22});
23
24app.listen(port, () =>
25  console.log("Server running...")
26);

Step 2: Create a scheduled job

npx @booper/cli run \
  GET https://healthcheck.me.repl.co/api/run \
  --every "10 seconds"

Step 3: Monitor your jobs

When jobs fail they will be retried again in the future using an exponential backoff algorithm.

Webhook events

Your jobs and the HTTP requests they execute are logged and emitted as webhook events.

Idempotency support

Optionally set idempotency keys on your jobs to ensure they are never run more than once.
