The short version

  • Only Pants Build has a free tier, so it costs nothing to try first.
  • Each has a real cost: Pants Build smaller community compared to Bazel with fewer third-party tool integrations; 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.
  • They diverge on capability: Pants Build covers Intelligent defaults, Sumsub covers Document verification.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Pants Build

  • Smaller community compared to Bazel with fewer third-party tool integrations
  • Python plugin API steeper learning curve for custom build rules
  • Less mature ecosystem for non-Python languages
  • Fewer integration examples for enterprise CI/CD platforms

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

Pants Build: What languages does Pants support?

Pants supports Python as a first-class citizen, with production-ready support for Go, Java, Scala, Kotlin, Shell scripts, and Docker.

Source

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.

Pants Build: Do I need to write BUILD files with Pants?

Pants uses static analysis to infer dependencies and project structure, minimizing required BUILD file configuration compared to other build systems.

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.

Pants provides file-level dependency tracking, multiple dependency resolves with lockfiles, and sophisticated dependency analysis that works correctly even with circular or complex dependency graphs.

Source
Sumsub: Does it cover business verification?
