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.

Postman

  • Free plan limited to single user as of March 1, 2026, making it unsuitable for teams without paid plans
  • Only 25 collection runs per month and 1,000 API calls/month on free tier
  • Removed local-only Scratch Pad mode in 2023, forcing cloud account creation and sync
  • Requires Postman account and internet connection for most features
  • Cloud-first architecture with mandatory syncing to Postman's cloud servers
  • No CI/CD integration or advanced security features on free plan

Answered from the vendors’ own pages

Alkami: Does Alkami replace our core?

No. It is the digital channel and account opening layer on top of a core such as Fiserv, Jack Henry or FIS.

Postman: What is the cost of Postman?

Postman has a free plan limited to 1 user, 25 collection runs/month, 1,000 API calls/month. Team plans start at $14/user/month for Basic. Professional at $29/user/month, and Enterprise at $49/user/month.

Source
Alkami: How is it priced?

Per registered user per month on multi year contracts with minimums, so model your enrolled user count rather than your active user count.

Postman: Can I use Postman offline?

Postman requires an internet connection to sync collections to the cloud. Since 2023, the Scratch Pad local-only mode was removed. Users must sign in with a Postman account, and collections sync to cloud by default. Offline work is possible but limited without cloud sync features.

Source
Alkami: What did the MANTL acquisition change?

It brought deposit account opening in house, announced February 2025 at $400 million enterprise value, so account opening and digital banking can come from one vendor.

Team collaboration is not available on the free plan (limited to 1 user). Team plans start at $14/user/month and include shared workspaces, real-time collaboration, and team management features.

Source

Source
Postman: Does Postman work with other development tools?

Postman integrates with Git repositories, offers a Node.js runner (Newman) for automation, and connects with popular CI/CD platforms. Teams using git-native workflows may prefer alternatives like Bruno.
