Deep S3 Observability
Break down billions of objects into their top prefixes directly in your account. s3lim surfaces hidden costs and optimization opportunities without your data ever leaving your VPC.
Stop S3 Bill Bloat
Actionable Storage Insights
Duplicate Detection
Identify identical files across prefixes and buckets. Surface redundant data that is silently inflating your monthly bill.
Prefix Hotspots
Instantly find which folders are growing fastest. Pinpoint 'hot' storage areas that need Lifecycle or Intelligent Tiering policies.
Ghost Versions & Incomplete Uploads
Find and remove non-current object versions, delete markers, and incomplete multipart uploads that silently add up to significant hidden storage overhead.
Zero Egress Security
Analyze your storage in-place. No data ever leaves your account, ensuring 100% compliance and zero data transfer costs.
MCP Server
Expose optimization reports directly to AI assistants. Connect tools like Claude Desktop or Amazon Q to audit S3 storage costs using natural language.
Native to AWS
Deploys directly as a Lambda function. Manage everything via the AWS Console and analyze in CloudWatch with zero infrastructure to maintain.
Simple, Volume-Based Pricing
Pay Only for What You Analyze

On the Horizon
S3 Performance & Security Auditing
We are actively building stateless, in-account analysis engines for S3 Server Access Logs to provide real-time performance troubleshooting and active threat detection.
Latency Diagnostics
Identify slow S3 operations and surface p95/p99 turnaround latency hotspots mapped directly to prefixes.
Shadow Access Audit
Detect requests coming from external AWS accounts, public IPs, or unexpected IAM principals.
Bulk Egress & Ransomware Alerts
Get notified of sudden exfiltration volume spikes or mass delete operations per client IP in near-real-time.
Sensitive Data Scanner
Identify unencrypted PII, API tokens, and secret credential patterns across bucket prefixes with zero data egress.
Compliance Drift
Continuously audit storage postures against organizational retention mandates, Object Lock immutability, and encryption policies.
