AI code completion tool with a security/enterprise focus — offers a fully self-hosted/on-prem deployment where no code ever leaves the customer's infrastructure. Pricing: Dev $9/user/mo (annual, cloud), Enterprise $39/user/mo (SSO, admin controls, on-prem option), Enterprise-plus custom. Popular with regulated industries (finance, healthcare, defense) that can't use cloud AI coding tools.

What each is best for
Postman is worth it if… engineering teams (3-500 developers) that build, test, and consume APIs — particularly if you have more than 5 developers hitting the same API surface. Free covers solo learning + hobby projects (3 collaborators); Basic adds unlimited history and version control; Professional adds unlimited collaborators, SSO add-on, and 100K API calls; Enterprise adds SCIM, audit logs, and unlimited scale.
Tabnine is worth it if… regulated enterprises (banks, hospitals, defense) that need AI code completion but cannot ship code to a cloud LLM. Dev tier at $9/user/mo is competitive but the strategic sale is Enterprise at $39/user/mo where the on-prem model runs entirely inside customer infrastructure.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
