S3-Compatible API Migration Tester

3.15

Derivation Chain

Step 1 Spread of object-storage queue architectures
→
Step 2 Rise of S3-compatible storage alternatives
→
Step 3 Automated S3 API compatibility testing tool

Problem

When dev teams of 5–20 people adopt S3-compatible object storage (MinIO, Cloudflare R2, Wasabi, turbopuffer), they spend 1–2 weeks manually testing which of the 200+ S3 API endpoints their existing S3 SDK code actually uses and whether each one is compatible with the target storage.

Solution

Automatically extracts S3 API call patterns from an existing codebase and generates/runs a compatibility test suite against the target storage. Delivers a per-API compatible/incompatible/partially-compatible report along with suggested migration code patches.

Target: Backend engineers at 5–20 person SaaS Startups evaluating a switch from S3 to alternative storage
Revenue Model: Per-test-run at 29,000 KRW (~$22), or monthly flat rate at 79,000 KRW (~$59) for unlimited tests + CI/CD integration
Ecosystem Role: Supplier
MVP Estimate: 2_weeks
