Cut your CloudWatch Logs bill 70-90%: multi-account drain to zstd S3, WORM/Object Lock compliance, and a cost dashboard.
Overview
S4 Logs Commercial cuts the two big lines on a CloudWatch Logs bill: ingest and storage. Mode A drains existing log groups to S3 as standard zstd, cutting the storage line by 50-70% on S3 Standard and around 90% with Glacier Instant Retrieval. Mode B is a PutLogEvents-compatible gateway that writes straight to the archive, bypassing ingest - the dominant cost for most accounts and the source of the headline 70-90% reduction.
Archives are deliberately lock-in-free: every object is standard zstd, readable with plain zstd -dc, the open-source s4logs CLI, or Amazon Athena. Cancel the subscription and your data stays fully usable.
The commercial layer adds what enterprises need on top of the open-source core:
-
AWS Organizations multi-account drain: discover member accounts (all, by OU, or explicit), assume a drain role deployed via the included StackSet template, and drain every account into one aggregate bucket with per-account partitions. Retention gates are fail-closed.
-
WORM retention: S3 Object Lock in Governance or Compliance mode (SEC 17a-4). Every object is integrity-verified against its manifest before locking; a verification failure leaves the object mutable instead of locking a diverging copy. A per-object audit JSON is emitted for evidence.
-
Cost-savings dashboard and restore-search web UI: a single token-gated binary showing estimated monthly savings, per-group breakdowns, and a search-then-restore workflow that reads only manifest-pruned ranges from S3.
Deployment is one-click: the included CloudFormation quickstart creates an Object-Lock-enabled archive bucket, an instance role, and the dashboard instance. The AMI ships both the open-source s4logs CLI and the commercial s4logs-pro binary. No license keys - running the AMI is the entitlement. Billed hourly with an annual option.
Highlights
- AWS Organizations multi-account drain into one lock-in-free archive
- WORM / S3 Object Lock (Governance + Compliance), verified before locking
- Cost-savings dashboard + restore-search UI (single binary)

Dimensions summary
You pay an hourly software fee that varies by the EC2 instance type you run S4 Logs on. The 13 dimensions map to different instance families and sizes, including general-purpose (t3, t3a, m5, m6i, m7i) and compute-optimized (c6i, c7i) options. Larger sizes carry a higher hourly rate and suit higher log ingest rates. You choose one instance type based on your workload. This software fee is billed separately from the underlying EC2 compute charge, and an annual option is available.
Top-of-mind questions for buyers
The hourly fee covers only the S4 Logs software license, metered per running instance. You also pay the underlying EC2 compute for the instance you launch, plus S3 storage and data transfer. These appear separately on your AWS invoice. The software runs in your own account and VPC.
You match the instance size to your log ingest rate. Higher ingest rates need a larger instance carrying a higher hourly rate. You run one instance type at a time. Your software fee stays constant per hour for that instance, so heavier logging means choosing a bigger instance, not per-gigabyte charges.
The software fee meters per running instance-hour. A fully stopped instance does not accrue the hourly software charge. Stopped instances may still incur underlying AWS storage costs for the attached volume, but the S4 Logs license bills only while the instance runs.

Vendor refund policy
Hourly usage is billed as incurred and is non-refundable. For annual (upfront) subscriptions, contact support@abyo.net within 14 days of purchase to request a refund; approved refunds are issued through AWS Marketplace. AWS infrastructure charges are set and billed by AWS and are not refundable by the seller. The open-source S4 Logs core (Apache-2.0) remains free to self-host.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Tracks open-source s4-logs v1.2.0. The bundled s4logs CLI adds 'drain --follow' (a continuous-archiver daemon that drains complete windows on an interval and runs a periodic late-arrival reconcile sweep) and 'serve --auth-keyring' (multi-key SigV4 verification with operator-issued session tokens). Hardening across the shared S3, TLS, EMF and observability layers, verified by an expanded fuzz and mutation suite. No on-disk format change; archives written by earlier versions remain readable.
Additional details
Usage instructions
Launch via the deploy/cloudformation/s4logs-quickstart.yaml stack (creates the Object-Lock archive bucket + instance role + dashboard). Dashboard on port 8088 with the S4LOGS_WEB_TOKEN bearer token. For AWS Organizations fan-out also deploy s4logs-org-stackset.yaml.
