QStash: Messaging for the Serverless | Upstash Blog
July 18, 2022 - Formally, QStash is a message queue and task scheduler designed for serverless runtimes.
How are the messages priced? Are retries free?
The only thing you are charged for are messages whereas retries are free. Below are some message examples: Publish to single API endpoint. Here you would be charged for 1 message.

How is the Max Message Size Limit applied?
If the body send to QStash is larger than the limit, the endpoint returns http 412 error stating that quota is exceeded. When /v2/batch endpoint is used, each request body is subjected to the quota on its own. When the response of called endpoint is larger than the limit, the message is trimmed after the limit. And stored in the DLQ/Events as trimmed.

r/dartlang on Reddit: QStash - HTTP based messaging and scheduling solution for serverless apps
October 18, 2022 -
I just released Qstash, A message broker between your serverless apps. You send an HTTP request to QStash, that includes a destination, a payload and optional settings. We durably store your message and will deliver it to the destination API via HTTP. In case the destination is not ready to receive the message, we will retry the message later, to guarentee at-least-once delivery.
Features:
100% serverless, no stateful connections required. Messages are pushed to your API.
At-least-once delivery guaranteed to any public API
Pubsub via topics
Delay message delivery
Message deduplication
Scheduling via CRON

what about the situation when i just want to simply push the message to the code, not waiting for the callback and response

We stumbled across this as we were researching setting up our own solution. In our case, we are receiving third-party webhooks which we want to queue. We could point them to Qstash, but really can't do anything else with them before sending to Qstash. Is this a viable use case?

Parallelism and Rate Limit for Workflow And QStash | Upstash Blog
February 20, 2025 - Rate Limit: This defines the maximum number of calls per second. Calls within the same FlowControl key contribute to the rate count. Instead of rejecting excess calls, QStash delays them for execution in later seconds, respecting the limit.

r/django on Reddit: What's your take on Celery vs django-qstash for background tasks
July 5, 2025 -
Hello guys, I'm currently working on a personal project and would like to know your thoughts and advice on handling background tasks in django.
My use cases includes:
Sending transactional emails in the background
Some few periodic tasks
Celery is super powerful and flexible, but it requires running a persistent worker which can get tricky or expensive on some platforms like Render. On the other hand, QStash lets you queue tasks and have them POST to your app without a worker — great for simpler or cost-sensitive deployments.
Have you tried both? What are the treadoffs of adopting django-Qstash.

Celery is super powerful and flexible, but it requires running a persistent worker which can get tricky or expensive on some platforms like Render. I've never used this platform, but I just spent a minute looking at their docs for deploying Celery, and ... this seems fine? I'm not sure what you mean by it being expensive or complex. Have you tried both? What are the treadoffs of adopting django-Qstash. Celery is going to be significantly more popular, and most issues that you run into with Celery will have documentation or StackOverflow posts that explain how to work around it. There is something to be said for using the solution that has been tried and tested a thousand times. Many fewer unknown unknowns. My gut reaction is that if you build your application on a common set of abstractions (e.g. redis, any celery-compatible queue) you will have significantly more freedom to switch providers than if you implement a library that is tied to a single cloud provider. Vendor lock in = $$$

Gonna glob onto this one - I’ve been using crontab for my automations and have noticed some slowdown when one of my /3 min scripts runs. Would celery help reduce memory & cpu consumption, or is the real benefit being able to programmatically schedule?
