Runtimes & workflows
Durabull vs Amazon SQS + Step Functions
SQS and Step Functions can replace Redis + BullMQ. They do not inspect BullMQ jobs. Estimate SQS from send, receive, and delete requests, including empty receives; add Step Functions only if you use it for orchestration. Batching can reduce request costs.
Choose SQS when you are already on AWS, want a managed broker with an AWS SLA, and will write AWS-native workers.
Choose Durabull when your Node.js workers already use BullMQ. Moving to SQS means rewriting producers and workers; Durabull connects with a Redis URL.
Capabilities
The details that change the decision
| Feature | Durabull | SQS |
|---|---|---|
| 1M jobs, 3 SQS requests each | Free to start + your infrastructure | $0.80 after free tier |
| Same + 4 Step Functions transitions | Free to start + your infrastructure | ~$100.70 + Lambda |
| Understands BullMQ | Yes | No |
Setup
How SQS connects
AWS SDKs and APIs. Workers poll SQS or are invoked by Step Functions.
Application changes. Yes to leave BullMQ.
- Queue discovery
- N/A.
- Environments
- AWS accounts and regions.
- Alerts
- CloudWatch alarms. Not BullMQ rules.
- AI & MCP
- AWS Labs publishes open-source MCP servers for SNS/SQS (manage queues, send and receive messages) and for running Step Functions state machines. None reads BullMQ.
Economics
Understand what you are paying for
- SQS pricing
- As of 2026-10-20 (AWS Price List published 2026-09-11): SQS Standard in us-east-1 is $0.40 per million requests after 1M free requests per month; FIFO is $0.50 per million. Step Functions Standard is $0.000025 per state transition after 4,000 free per month. Express is $1 per million requests plus duration.
- SQS license
- Proprietary AWS managed services.
- Durabull
- Hosted dashboard is free to start. Redis, worker compute, and infrastructure operations remain your costs. Check the pricing page for current terms. Apache License 2.0 (OSI-approved open source). Self-host on your own infrastructure.
| Volume | Runtime / product charges | Durabull hosted fee | Unit |
|---|---|---|---|
| 1M jobs (SQS only) | $0.80 | Free to start + your infrastructure | 3 API requests/job |
| 10M jobs (SQS only) | $11.60 | Free to start + your infrastructure | 3 API requests/job |
| 100M jobs (SQS only) | $119.60 | Free to start + your infrastructure | 3 API requests/job |
SQS Standard in us-east-1, pricing as of 2026-10-20: payload under 64 KB, no batching, three requests per job, no retries or empty receives, and the full 1M monthly free-request allowance available. Excludes compute, data transfer, KMS, and Step Functions. Durabull’s free-to-start hosted dashboard excludes Redis, workers, and operations.
Questions about SQS and Durabull
Is SQS cheaper than BullMQ?
It depends on workload and infrastructure. SQS charges for requests; BullMQ uses Redis and workers you provision. Include polling, payload sizes, batching, compute, and operational effort. Step Functions is an optional additional service, not a required SQS charge. Durabull adds a hosted dashboard that is free to start.
