- Depot Pick
- Stripe · 8.83/10 for this job (curated estimate, high confidence)
Stripe Financial Connections links accounts with instant verification, balance and ownership checks, and feeds directly into ACH Direct Debit — one integration from link to settled payment with NSF-aware balance refresh.
- Runner-up
- Nango · 8.17/10
Scores higher than the pick on: Price / performance, Lock-in risk (higher = worse).
- When not to use the pick
- Need a generic OAuth/token vault for many non-bank SaaS APIs — Nango; enterprise SSO/directory sync around the linking flow — WorkOS; card-side (not bank-side) controls — Lithic; passwordless end-user auth before linking — Stytch. Plaid/MX/Finicity are dedicated aggregators outside the frozen catalog (architectural guidance only).
- Lock-in / migration
- Runner-up Nango has lower stored lock-in risk (3.5 vs 6, 0–10, higher = more lock-in).
- Sourced price (no comparable unit)
Pick: no sourced price in this job's unit (no_matching_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
- No failure mode plainly applies to this job (no_failure_mode_plainly_applies).
