Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Alkami

  • Pricing is per registered user with contractual minimums, so institutions with many enrolled but dormant users pay for accounts that never log in.
  • Alkami is a channel layer, not a core, so functionality is bounded by what the core exposes, and a poor core integration produces a slow product no amount of channel work fixes.
  • Implementation typically runs six to twelve months and requires institution staff time, which small credit unions consistently underestimate.
  • The MANTL acquisition adds account opening but also another integration programme, and consolidating on one vendor removes leverage to swap a weak module for a best of breed alternative.
  • Buying digital banking separately from the core vendor means you own the integration risk between two suppliers who will each blame the other when something breaks.

Supabase

  • Free tier projects auto-pause after 1 week of inactivity
  • Free tier hard caps: 500 MB database, 1 GB file storage, 5 GB egress/month, 50,000 monthly active users, max 2 active free projects per organization
  • Pro plan charges usage overages beyond included quotas, e.g. $0.00325 per MAU above 100,000 and $0.125/GB disk above 8 GB
  • SOC2/ISO 27001 certification and HIPAA (add-on) compliance require the $599/month Team plan; not available on the $25/month Pro plan
