Queue as a service, powered by HTTPS ⚡️
Zeplo (previously Ralley) launched on July 9, 2020 with 235 votes, #82 of 4,305 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 6 years on.
What it does
Zeplo is a modern infinitely scaleable managed message queue (queue as a service), which requires no setup. Ralley works like any other queue, but instead of pushing jobs, you push requests.
Add retry, delay, queue and schedule to your HTTP requests without Redis, RabbitMQ or SQS. Just prefix any URL with zeplo.to/
