Where each one falls short

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

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

Sumsub

  • The published per-verification rate is undercut by a monthly minimum of 149 or 299 dollars, so low volume businesses pay a much higher effective rate than the headline suggests
  • You are billed per verification attempt in most configurations, meaning applicant drop-off and resubmissions cost money without producing a customer
  • Pass rates and document support vary noticeably by country, and a market that works well in Europe can produce materially worse rejection rates in parts of Africa and South East Asia
  • The AML screening tier bundles list coverage that large institutions would normally buy separately and tune, giving less control over match thresholds than a dedicated screening vendor
  • The company originated in Russia before restructuring to a UK entity, and some financial institutions still raise that history in vendor risk review, which can slow or block procurement at conservative banks

Answered from the vendors’ own pages

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
Sumsub: What does a verification actually cost?

1.35 USD on Basic and 1.85 USD on Compliance, but with 149 and 299 USD monthly minimums respectively. Below roughly 110 or 160 checks a month you are paying the minimum, not the rate.

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
Sumsub: Do failed verifications get charged?

Attempts are generally billable, so a poor onboarding funnel raises your bill. Confirm the exact resubmission policy in your contract.

Postman: Does Postman have team collaboration?

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
Sumsub: Does it cover business verification?

Yes, KYB with company registry lookups and beneficial owner resolution is part of the platform rather than a separate product.

Postman: What are the free plan limits?

Free plan allows: 1 user only, 25 collection runs per month, 1,000 API calls/month, and 1,000 mock server calls/month. No CI/CD integration or advanced security features.

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.
