Head-to-Head Comparison
STRG vs Cloudflare R2 Pricing (2026)
Both charge $0 for outbound traffic. The difference is the other two meters: STRG bills a flat $6.80/TB with $0 standard S3 requests, while Cloudflare R2 bills $15.00/TB and charges $4.50 per million Class-A writes beyond its free allowance. At 5 TB stored and 5 TB served the engine prices STRG at $33.93 and R2 at $74.85. On a read-heavy workload the flat rate decides it; on a write-heavy one R2's request meter does.

Cost profile: where each provider wins
What STRG is good for 🏆 Gold Standard
- ✓ Flat $6.80/TB per month with all egress and standard S3 requests included
- ✓ No minimum storage duration and no retrieval fees
- ✓ Object Lock for immutable retention
- ✓ MCP server for AI agents at mcp.strg.com/mcp
Constraints to plan around:
- ! Two regions only (EU-Central Amsterdam, US-East Reston)
- ! No published availability SLA figure: the vendor states service levels are agreed per contract
- ! Versioning is always on and every stored version is billed as stored data, so overwriting or deleting an object keeps billing its older versions until a lifecycle policy removes them
What R2 is good for
- ✓ Largest edge network of the two, with native Cloudflare Workers bindings
- ✓ 10 GB free storage plus monthly Class-A and Class-B free allowances
- ✓ Instant cache and CDN integration on the same account
Constraints to plan around:
- ! Class-A writes cost $4.50 per million once the free allowance is used
- ! Egress is free but request volume is not, which matters for chatty small-object workloads
- ! Storage rate is more than double the STRG flat rate
