Amazon SQS vs Zeplo
SEPT 2026 auditA comparison of Amazon SQS and Zeplo built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
Choose Amazon SQS if…
AWS-resident systems that want a queue with a permanent free million requests a month and no capacity to plan — SQS scales without a throughput setting to choose.
Editorial · Palash Bagchi · approved
Choose Zeplo if…
Turning an HTTP endpoint into a queued, retried job without running a consumer — and keeping a month of logs while doing it, which nothing else here offers on a free plan.
Editorial · Palash Bagchi · approved
Consider something else if…
- Amazon SQS: Billing is per request rather than per message, and a 1 MiB payload counts as sixteen, so chatty polling or large messages cost far more than the message count suggests.
- Zeplo: The free tier's overage is $20 per 100,000 requests, twenty times the Company plan's rate, so staying free past 500 requests is the most expensive way to use it.

At a glance.
| Criterion | Amazon SQS | Zeplo |
|---|---|---|
| Pricing | ||
| Free tier | Yes | Yes |
| Kind of free offer | Free tier | Free tier |
| Entry paid plan | No paid plan or minimum fee; billed per request after the free 1 million requests a month. | $39/month for Company, including 1,000,000 requests and three team members. Additional members are $15 each. |
| Pricing model | Per request, not per message: every API action counts, and a 1 MiB payload is billed as 16 requests. FIFO queues cost $0.50 per million against standard's $0.40 in us-east-1, and fair queue requests add $0.10 per million on top of the standard rate. | Per HTTP request rather than per message or per execution, with unlimited jobs on every tier and team size as a separate axis — three members included on Company, $15 for each beyond. |
| Infrastructure | ||
| Regions | 34 commercial AWS Regions plus 2 AWS GovCloud (US) Regions listed in the SQS service endpoints table. | Hosted on Google Cloud Platform; no selectable region is offered and data may be transferred between countries. |
| Queues | ||
| Included per month | 1,000,000 requests a month free, permanently and across all regions. Beyond that, standard queues are $0.40 per million in us-east-1, falling to $0.30 above 100 billion and $0.24 above 200 billion. | 500 requests free, then $20 per 100,000. The Company plan includes 1,000,000 requests and charges $10 per million beyond — five times cheaper per request than the free plan's overage rate. |
| Maximum message size | 256 KB per message. A single request carries 1 to 10 messages up to 1 MiB total, and each 64 KB chunk of payload is billed as one request. | 256 KB inline request body (unlimited via S3 offload); plan payload caps are 64 KB on Developer and 1 MB on Company. |
| Message retention | 4 days by default; configurable from 60 seconds up to 14 days per queue. | 30 days of log retention on every plan — free, Company and Enterprise alike. The longest window in this category by a wide margin. |
| Maximum delay | 15 minutes maximum per-message delay (message timer) or per-queue delay; default is 0 seconds. | 30 days (2,592,000 seconds) maximum delay_seconds per request. |
| Concurrency | Approximately 120,000 in-flight messages per standard queue (received but not yet deleted); API call rate on standard queues is nearly unlimited. | API rate limit rather than a concurrency figure: 100 requests/min on Developer (Free) and 2,000 requests/min on Company ($39/mo). |
| Dead letter queue | Supported | Limited — Dead-letter handling is a webhook fired on permanently failed requests, not a separate queue you consume. |
| Compliance | ||
| GDPR / data residency | AWS customers can process personal data on all AWS services in compliance with GDPR, and choose the storage type and geographic region for their data. | Privacy policy permits storage, processing and transfer of personal information between any of the countries in which Zeplo operates. zeplo.io policy, last updated February 7, 2022; the newer v2.zeplo.io policy is silent on transfers. |
| Encryption at rest | Server-side encryption of queue contents with SQS-managed keys (SSE-SQS) or AWS KMS keys (SSE-KMS). | Privacy policy states industry-standard measures including encryption in transit (TLS), encryption at rest, and access controls. v2.zeplo.io policy, last updated February 21, 2026; no cipher or key-management detail published. |
| Role-based access control | IAM identity-based policies on users, groups and roles plus resource-based queue policies control access to queues and actions. | Workspaces support multiple members with role-based access; roles are admin, member and viewer. Team invites are managed in the dashboard under Settings, Team; the API invite endpoint takes the same three roles. |

When these numbers change, hear about it. Sources are re-checked monthly; a repricing goes out as a short note.
Documented by only one.
These criteria are published by one provider and not the other. An absence here means we have not found a source, not that the feature is missing — except where we say we read the other provider's own page on a given date and it does not state it. Those rows lean, and the provider can correct them with a link.
Questions this comparison answers.
