- Depot Pick
- Turbopuffer · 8.35/10 for this job (curated estimate, high confidence)
Cost architecture pick. Confidence: high for Turbopuffer object-storage thesis.
- Runner-up
- Tigris · 8.30/10
Scores higher than the pick on: Developer & agent DX, Lock-in risk (higher = worse).
- When not to use the pick
- Managed Pinecone simplicity wins, or R2/Tigris alone if you bring your own ANN.
- Lock-in / migration
- Runner-up Tigris has lower stored lock-in risk (3.2 vs 4.5, 0–10, higher = more lock-in).
- Sourced price (no comparable unit)
Pick: no sourced price in this job's unit (no_sourced_price).
No cheapest SKU (no_comparable_unit_for_job). No price was invented.
- Free option
- No free resource lists this job. A cheap paid SKU is not a free option.
- Failure modes to watch
- Context overflow: If the input exceeds the window, say so and retrieve a narrower slice. Do not answer from a truncated head as if it were the whole source.
- Stale retrieval: Store the source URL and the time it was fetched. If a newer canonical page exists, or two stored sources disagree, do not answer from the older one.

Runners-up
Tigris
R2 remains Depot object-storage / cheap-egress default (CDN+Workers gravity). Tigris when you want global…
Cloudflare R2
Depot pick when agent artifacts get downloaded a lot. S3-compatible without the egress grief.
Pinecone
Still the zero-ops vector default. If you already run Postgres, try pgvector before paying Pinecone rents.
Amazon S3
Default object store gravity well. Consider R2/Cloudflare or DO Spaces when egress dominates.
When NOT to use the top pick
Managed Pinecone simplicity wins, or R2/Tigris alone if you bring your own ANN.
