Push work to a queue and receive HTTP callbacks when it runs. Priorities, delays, and retries handled for you.
Task queues
Push tasks to queues with priorities, delays, and rate limits. Tasks deliver to your HTTP endpoints with automatic retries and dead-letter handling for failures.
Capabilities
Tasks process in the order they were added. Guarantee sequential processing when order matters.
Assign priorities to queues. Higher priority queues process before lower priority when both have pending tasks.
Schedule tasks to process after a delay. Send reminder emails 24 hours after signup without cron jobs.
Limit how fast tasks deliver to avoid overwhelming downstream services. Respect external API rate limits automatically.
Failed tasks retry with configurable backoff. Transient failures recover without manual intervention.
Tasks that fail all retries move to dead-letter queues. Inspect, debug, and reprocess failed tasks.
Tasks that fail all retries move to dead-letter queues. Inspect, debug, and reprocess failed tasks.
Task pickup time
No practical limit
At-least-once delivery
Why it matters
Push an image processing task. Queues calls your /process-image endpoint with the payload. Your serverless function runs, processes the image, and returns. No workers to scale or monitor.
Sync 10,000 records to an API that allows 100 requests per minute. Push all tasks to the queue with a rate limit. Queues delivers exactly 100 per minute without overwhelming the API.
A task fails because an external API is down. Retries happen at 1, 5, 15, and 60 minutes. If all fail, the task moves to dead-letter. When the API recovers, replay from dead-letter.
Built for Your Workflow
Push tasks to queues with HTTP endpoint targets. Conjoin dequeues tasks and calls your endpoints without requiring persistent worker processes.
Process background jobs on serverless platforms without worker infrastructure.
Configure rate limits per queue. Conjoin delivers tasks at the specified rate, preventing you from exceeding external API limits regardless of how fast tasks are enqueued.
Respect API rate limits without building throttling logic.
Push tasks with delay parameters. Tasks hold in the queue until the delay expires, then process normally with the same retry and delivery guarantees.
Schedule future tasks without building scheduling infrastructure.
Tasks that fail all retry attempts move to dead-letter queues. Inspect failed tasks with their error messages, fix the underlying issue, and replay them with one call.
Recover failed tasks without building failure tracking or replay logic.
