Editorial take
Why it stands out
Terraform should be positioned as the ecosystem-default IaC reference point, but the copy needs to distinguish clearly between the free OSS tool and HashiCorp's commercial platform layers.

Tool profile
Open-source infrastructure-as-code standard with an enormous ecosystem and optional HashiCorp platform layers for managed workflows.
Declarative infrastructure provisioning across clouds and services
Terraform still deserves inclusion because it remains one of the defining infrastructure-as-code tools in modern cloud stacks. Its core value is familiar by now: declarative infrastructure management across cloud providers, SaaS systems, and on-prem environments through a huge provider ecosystem. That ecosystem gravity is exactly why it remains such a high-value tool entry for the directory.
The pricing story needs to be framed carefully. Terraform itself is open-source software and free to use. The commercial layer comes from HashiCorp's platform offerings around managed workflows, governance, and enterprise controls. HashiCorp's pricing page now frames commercial access under IBM HashiCorp Cloud Platform with pay-as-you-go, Flex, and Enterprise Self Managed options, plus a $500 credit to get started. That means Terraform is both a free OSS standard and a platform buy, depending on how much collaboration, policy, and hosted workflow support the team wants.

Apache Kafka

Open-source distributed event streaming platform for high-throughput pipelines, pub/sub, and stream-processing ecosystems.
Choose Kafka when replayable event streams and ecosystem breadth matter more than the lightest possible operational footprint.
Pricing snapshot
Terraform OSS is free to use. HashiCorp's commercial pricing now routes through IBM HashiCorp Cloud Platform, which advertises pay-as-you-go billing, Flex plans, Enterprise Self Managed options, and a $500 starting credit. Public pricing is therefore clearest at the platform-model level rather than as a single flat Terraform subscription.
