Queues as a service for webhooks, AI jobs, and async work.
Publish jobs via REST API. SimpleQ queues them, retries failures, respects rate limits, and delivers to your webhook — you handle the business logic.
Built for teams shipping AI, SaaS, automation, and async-heavy products
Every team rebuilds the same fragile async infrastructure.
Async work is the duct tape of every modern app — and it breaks in the same ways everywhere. SimpleQ replaces it with managed queues and reliable webhook delivery.
Webhooks fail silently
Downstream endpoints go down, time out, or rate-limit you — and without retries, events are lost forever.
Rate limits break delivery
Bursty traffic overwhelms downstream APIs and your jobs start 429ing or dropping.
Background jobs disappear
Process restarts, deploys, or memory pressure quietly delete in-flight work.
Retry logic becomes messy
Every team rebuilds backoff, idempotency, and dead-letter queues the hard way.
No acknowledgment guarantees
You fire a webhook and hope it worked. No ack protocol, no timeout handling, no way to know if work actually completed.
Teams lack visibility
No dashboards, no per-job logs, no attempt history — debugging is grep and prayer.
SimpleQ handles delivery so your team can build product.
One REST API for queues, retries, rate limits, webhook delivery, and dead-letter queues. Drop it in, ship the next feature, sleep through the night.
Queue async jobs
Publish jobs via REST API with idempotency keys. SimpleQ queues them and POSTs to your webhook when ready.
Webhook-based delivery
You handle the business logic in your webhook. SimpleQ handles queuing, delivery, retries, and signing.
Retry failures automatically
Exponential or fixed backoff, configurable max attempts, and dead-letter queues out of the box.
Per-queue rate limiting
Control how fast jobs are delivered with per-queue rate limits — never overwhelm a downstream API.
Monitor every job execution
Per-job logs, attempt history, payloads, and one-click DLQ replay from the dashboard.
Smart backpressure handling
429, 503, and 529 responses are handled as backpressure — SimpleQ waits and retries without burning attempts. Built for AI APIs that return Retry-After headers.
Does this sound like your team?
SimpleQ is built for teams that need reliable async delivery without managing queue infrastructure.
“You're building with LLMs and tired of dropped jobs.”
Queue OpenAI, Anthropic, or Bedrock calls with per-queue rate limiting, 429/529 backpressure handling, and idempotent retries. Use ack mode for calls that run longer than 15 seconds.
“You're running SaaS webhook delivery and need retries + DLQ.”
Per-customer queues with HMAC signing, configurable exponential backoff, dead-letter queues, and bulk replay — all managed.
“You're migrating off self-hosted Redis + BullMQ.”
Drop the infra, keep the model. SimpleQ is a managed replacement with webhook delivery, built-in rate limiting, and a dashboard.
See the comparison →“You need rate-limited fan-out to a third-party API.”
Per-queue rate limiting with defer-on-backpressure so you never overwhelm a downstream — without burning retries.
One API to run reliable background work.
A single REST API call publishes a job. SimpleQ handles queuing, retries, rate limiting, and delivery to your webhook — no infrastructure to manage.
- Idempotency keys to prevent duplicate jobs
- Per-queue rate limits for downstream APIs
- Delayed jobs — process seconds, minutes, or hours later
- Dead-letter queues with one-click replay
- Ack mode with nack and defer for long-running async work
- Queue templates for AI workloads (e.g. Anthropic)
- HMAC webhook signing for security
- 429/503/529 backpressure handled without burning retries

From AI pipelines to webhook delivery, SimpleQ replaces the bespoke retry-and-rate-limit code your team keeps writing.
AI job processing
Queue LLM calls, retries on 429s and 5xxs, and deliver results to your webhook reliably.
Webhook delivery
Deliver events to customer webhooks with retries, backoff, HMAC signing, and dead-letter handling.
Bulk API operations
Fan out thousands of jobs with rate limiting so you never overwhelm downstream APIs.
Delayed jobs
Publish jobs with a delay — process them minutes, hours, or days later.
SMS and email workflows
Throttle outbound messages per queue and prevent duplicate sends with idempotency keys.
Ack-mode processing
Use ack mode for long-running work — webhook confirms receipt, your app calls /ack when done.

SimpleQ is HTTP-first today — any language that can make an HTTP request works. No self-hosting, no polling, no infrastructure to manage. SDKs for TypeScript, Python, Go, Java, PHP, and C#/.NET are coming soon.

Managed queues for every async workflow.
Every team rebuilds the same fragile queue infrastructure — retries, rate limits, dead-letter handling, webhook delivery. SimpleQ replaces all of it with a managed service. You handle the business logic, we handle the transport. One REST API, zero infrastructure to maintain.
