The short version

  • Only Bazel has a free tier, so it costs nothing to try first.
  • Each has a real cost: Bazel steep learning curve for developers unfamiliar with build systems; Signicat national eID scheme fees are passed through on top of Signicat's own charge, so a single-country business almost always pays less by integrating with the scheme directly.
  • They diverge on capability: Bazel covers Fast incremental builds, Signicat covers eID scheme brokering.
  • Prices and features above were last checked on 1 September 2026.

  • A public sector body needing cross-border recognition of notified eID schemes under eIDASnot Bazel

Where each one falls short

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

Bazel

  • Steep learning curve for developers unfamiliar with build systems
  • Initial setup complexity; requires BUILD files and Bazel configuration
  • Verbose error messages can be difficult to debug for new users
  • Smaller community and fewer third-party integrations vs enterprise tools

Signicat

  • National eID scheme fees are passed through on top of Signicat's own charge, so a single-country business almost always pays less by integrating with the scheme directly.
  • Value is concentrated in Northern and Western Europe, and coverage in Southern and Eastern Europe is thinner, so a pan-European rollout still hits gaps requiring document fallback.
  • Pricing is per transaction and quoted, and because scheme rates vary by country the cost per onboarded customer differs materially between markets in ways that complicate unit economics.
  • Each eID scheme connection typically carries its own setup fee and approval process, so adding a country is a project with a lead time rather than a configuration change.
  • Availability is tied to the national schemes, meaning an outage at BankID or MitID stops your onboarding entirely and there is no vendor-side mitigation for it.

Answered from the vendors’ own pages

Bazel: Does Bazel support distributed builds across CI infrastructure?

Yes, Bazel supports distributed execution and remote caching, allowing build work to be distributed across multiple machines and CI agents.

Source
Signicat: Is this an alternative to a document verification vendor?

Only where national eID exists. In markets with a mature bank ID scheme it is better; elsewhere you fall back to document checks, which Signicat also provides.

Bazel: What languages can be built with Bazel?

Bazel has built-in support for Java, C++, Go, Python, and Android/iOS development, with additional language support available through custom rules and community extensions.

Source
Signicat: Do we still pay the eID schemes?

Yes. Scheme fees are passed through in addition to Signicat charges. Ask for the split when comparing to a direct integration.

Bazel: Can I use Bazel for small projects or is it only for large monorepos?

While Bazel excels at handling large projects, it can be used for smaller codebases. However, the setup overhead may not be justified for very small or simple projects.

Source
Signicat: Are signatures legally qualified?

Signicat supports eIDAS qualified electronic signatures, which carry the highest legal standing in the EU, as well as advanced signatures.
