- Depot Pick
- Redis · 8.24/10 for this job (curated estimate, high confidence)
reliability + latency capability.
- Runner-up
- Supabase (pgvector) · 8.66/10
Scores higher than the pick on: Capability fit, Price / performance, Developer & agent DX, Privacy / data retention, Lock-in risk (higher = worse).
- When not to use the pick
- Durable relational memory — Postgres. Edge-only light state — Durable Objects.
- Lock-in / migration
- Runner-up Supabase (pgvector) has lower stored lock-in risk (3 vs 4, 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.

Redis
reliability + latency capability.
Pricing (directional): Redis OSS + Redis Cloud; vector search via Redis Query Engine; pay for memory-centric hosting.
Lock-in risk: higher = more lock-in (worse). Overall already inverts this dimension.
Use as agent hot memory/cache, not as your only 100M-vector archive.

Runners-up
Supabase (pgvector)
Depot default for most agent apps under ~25–50M vectors. Don't add Pinecone until Postgres actually hurts.
Cloudflare Workers
Best edge runtime for lightweight agent gateways and tools. Heavy LLM loops still belong on Modal/Fly/GPU…
Upstash Redis
Default serverless-edge-redis. Use classic Redis Cloud when you need always-on fat memory / Redis modules…
When NOT to use the top pick
Durable relational memory — Postgres. Edge-only light state — Durable Objects.
