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.

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
