The short version

  • Each has a real cost: Buildkite free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention; HashiCorp Boundary hashiCorp was acquired by IBM in February 2025 and Enterprise licensing now runs through IBM Passport Advantage; IBM has already retired HCP Vault Secrets, so Boundary's roadmap depends on IBM portfolio decisions rather than HashiCorp's own product strategy.

Where each one falls short

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

Buildkite

  • Free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention
  • Pro plan is $30 per active user per month, capped at 50 users, with only 10 of the up to 250 concurrent agents included before extra usage
  • Enterprise plan enforces a 30 user minimum even though pricing itself is custom
  • Hosted compute beyond included minutes is metered at $0.004 per vCPU minute on Linux and $0.02 per vCPU minute on Mac

HashiCorp Boundary

  • HashiCorp was acquired by IBM in February 2025 and Enterprise licensing now runs through IBM Passport Advantage; IBM has already retired HCP Vault Secrets, so Boundary's roadmap depends on IBM portfolio decisions rather than HashiCorp's own product strategy.
  • Enterprise pricing is not published anywhere, and the features most organisations actually need for compliance, notably session recording, are Enterprise only, so the free community edition is rarely the version you end up buying.
  • It solves access to infrastructure, not to applications; browser-based internal tools, SaaS admin consoles and APIs need a separate control, so Boundary is one component of a zero-trust programme rather than the whole thing.
  • Running it yourself means operating controllers, worker nodes and a Postgres database in a highly available configuration, and if that control plane is down nobody can reach production, which makes it a new critical dependency.
  • It is materially easier to adopt if you already run Vault and Terraform; teams without that ecosystem face a steeper learning curve than a device-based mesh product like Tailscale, for a similar access outcome.

Answered from the vendors’ own pages

Source
HashiCorp Boundary: Does it replace a VPN?

For infrastructure access, largely yes. It grants a session to a specific target rather than putting the user on a network, but it does not cover browser-based internal applications.

No, Buildkite's Pro plan is billed monthly at $30 per active user with no long-term contract required. All tiers include a 30-day all-access trial.

Source
HashiCorp Boundary: What does Boundary Enterprise cost?

HashiCorp does not publish Boundary pricing. It is quoted, and since the IBM acquisition it is transacted on IBM licensing paper.

Buildkite: What user limits apply to each Buildkite plan?

Free plan supports up to 5 users, Pro plan supports up to 50 users, and Enterprise plan provides unlimited users with a 30-user minimum.

Source
HashiCorp Boundary: Do I need Vault to use it?

No, but the just-in-time credential brokering that makes Boundary worthwhile depends on Vault or an equivalent secrets store.
