The managed job queue for AI and API-heavy backends.
Production-grade background jobs without building or running a queue. Publish over REST or the TypeScript SDK; SimpleQ delivers each job to your webhook — with retries, ack mode for long-running work, and backpressure that defers on 429s instead of burning your retry budget. No polling workers, no broker — your worker is a plain HTTP endpoint.
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 the bespoke retry, rate-limit, and dead-letter code your team keeps rebuilding with one managed queue.
Delivery fails silently
Your downstream LLM or third-party API times out, 429s, or goes down — and without retries, the job is lost with no record it ever ran.
Rate limits break delivery
Bursty traffic overwhelms a downstream API — OpenAI, Stripe, an internal service — 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 publish a job and hope it ran. No ack protocol, no timeout handling, no way to know if the 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 (or the TypeScript SDK) for queuing, retries, per-queue rate limiting, ack mode, and dead-letter replay. Drop it in, ship the next feature, sleep through the night.
Drop in — no new infrastructure
Publish over REST or the official TypeScript SDK. SimpleQ POSTs each job to a route in the app you already run — no polling workers, no broker, no framework to adopt.
Backpressure that never burns a retry
429, 503, and 529 with Retry-After auto-defer — a rate-limited job rides out the limit and still completes, without spending an attempt. Built for AI APIs.
Ack mode for long-running work
Return 200 fast, then report the real outcome with ack, nack, or defer — for LLM calls, video, and slow APIs that outlast a synchronous response.
Retries + dead-letter queue
Exponential or fixed backoff, configurable max attempts, and a DLQ with one-click replay — single or bulk, from the dashboard or API.
Per-queue rate limiting
One shared rate budget per queue controls delivery speed across every worker — never overwhelm a downstream API.
Observability + HMAC signing
Per-job logs, full attempt history, and payloads — plus HMAC-SHA256 signing and idempotency keys so every delivery is verifiable and safe to retry.
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 need a flaky downstream to degrade gracefully, not cascade.”
defer rides out 429/503/529 on the downstream's Retry-After — no attempt burned — so a rate-limited API can't blow through your retry budget or stall the queue.
See the comparison →“You're migrating off self-hosted Redis + BullMQ.”
Drop the infra, keep the model. SimpleQ is a managed replacement with push delivery to your endpoint, 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 up to 24h (one-shot)
- Dead-letter queues with one-click replay
- Ack mode with nack and defer for long-running async work
- Queue templates for AI workloads (Anthropic + OpenAI)
- HMAC webhook signing for security
- 429/503/529 backpressure handled without burning retries

From AI pipelines to bulk API sync, 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.
AI agent pipelines
Run multi-step agent and LLM pipelines where a dropped step can't break the chain — durable acceptance and idempotent retries keep every step alive.
Bulk API operations
Fan out thousands of jobs with rate limiting so you never overwhelm downstream APIs.
Backpressure handling
429/503/529 responses auto-defer with Retry-After — jobs ride out rate limits without burning attempts.
Delayed jobs
Publish a job with a delay and SimpleQ fires it later — up to 24 hours out, one-shot.
Ack-mode processing
Use ack mode for long-running work — webhook confirms receipt, your app calls /ack when done.
Coming from another queue?
SimpleQ is HTTP-first — any language that can make an HTTP request works, and the official TypeScript SDK (@simpleq/sdk) is available today. No self-hosting, no polling, no infrastructure to manage. More language SDKs are coming.
