Cloudflare R2
Depot pick when agent artifacts get downloaded a lot. S3-compatible without the egress grief. Strengths: S3 API without egress tax; Works with Workers; Simple global story.
Strengths
- S3 API without egress tax
- Works with Workers
- Simple global story
Weaknesses
- Feature parity gaps vs S3 occasionally
- Vendor coupling to CF ecosystem
- Consistency model nuances
Backblaze B2
Best cheap always-hot archive for datasets/checkpoints. R2 still wins agent artifact serving with unbounded free egress; Tigris for global $0 egress S3. Strengths: Dirt-cheap always-hot S3-compat; 3× free egress + partner zero-egress paths; Overdrive SKU aimed at training pipelines.
Strengths
- Dirt-cheap always-hot S3-compat
- 3× free egress + partner zero-egress paths
- Overdrive SKU aimed at training pipelines
Weaknesses
- Not $0 egress in the general case (R2/Tigris win that JTBD)
- Fewer edge/compute hooks than R2+Workers
- Overdrive is a serious commit
