CDKTF Deprecated - The End of HashiCorp's Programmatic IaC Experiment
HashiCorp (now IBM) has officially archived the CDK for Terraform project, ending a five-year experiment in programmatic infrastructure-as-code.

In this episode, we break down:
- Why CDKTF failed to find product-market fit (243K downloads vs Pulumi's 1.1M)
- The four key factors behind the deprecation: Pulumi's head start, JSII complexity, HCL "good enough", IBM acquisition timing
- Community reaction and the "rug pull" sentiment
- Migration paths: HCL (cdktf synth --hcl), Pulumi, OpenTofu, or AWS CDK
- What platform engineers should learn about vendor lock-in risk
Plus news on Envoy CVE-2025-0913 (CVSS 8.6), Google's managed MCP servers, OpenTofu 1.11, pgAdmin 4 v9.11, Lima v2.0, and Amazon ECS custom stop signals.
If you're on CDKTF, start your migration analysis this week. The programmatic IaC dream isn't dead—it just won't be at HashiCorp.
