The short version
- Each has a real cost: esbuild deliberately does not type-check TypeScript, only strips types, so tsc still runs separately; Vault vault 1.15.0 and later is licensed under the Business Source License 1.1, not an OSI open source licence, with IBM Corporation as licensor
- They diverge on capability: esbuild covers Very fast builds, Vault covers Secrets management.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
esbuild
- Deliberately does not type-check TypeScript, only strips types, so tsc still runs separately
- Plugin API is far narrower than webpack or Rollup, and complex builds hit its limits
- Code splitting support has historically lagged the more established bundlers
- Frequently used indirectly through Vite, so direct use is a narrower need than the download numbers suggest
Vault
- Vault 1.15.0 and later is licensed under the Business Source License 1.1, not an OSI open source licence, with IBM Corporation as licensor
- The Additional Use Grant forbids offering Vault to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Vault
- Each version only converts to MPL 2.0 four years after that version is published, and the Change Date is tracked per version
- Replication, HSM support, namespaces, performance standby nodes, FIPS builds, control group authorisation, multi-factor authentication, secrets sync and lease count quotas all require a Vault Enterprise licence
- A Vault Enterprise licence must be applied to the cluster before any Enterprise feature can be used
