Your infrastructure-as-code probably isn’t telling the truth. Terraform, OpenTofu and friends drift out of sync the moment someone clicks around in AWS. In this video we break down formae — a new open source IaC platform from Platform Engineering Labs that treats reality as the source of truth and keeps your cloud state continuously codified. Links: - Bespoke content: ?utm_source=yt-formae - Get formae: ?utm_source=yt-formae formae is a 100% code-driven, agent-based IaC tool that discovers everything in your AWS accounts, auto-generates strongly-typed PKL configuration, and merges out-of-band changes back into versioned code. No brittle state files, no manual imports, no guessing what’s actually running in production — just continuously up-to-date infrastructure code. We’ll walk through how formae compares to Terraform and Pulumi, why its patch vs reconcile modes matter for real-world platforms, and how its schema-safe configuration and background agent change the day-to-day life of DevOps, SRE and platform engineering teams. In this overview you’ll learn: - Why traditional IaC tools drift and break in messy, multi-tool cloud estates - How formae discovers and codifies existing AWS resources into versioned code - What PKL (Platform Kernel Language) is and how it replaces HCL in this model - How patch mode vs reconcile mode reduce blast radius for infrastructure changes - Why formae drops explicit state files and uses an agent-based architecture instead - How you can adopt formae incrementally alongside Terraform, Pulumi and ClickOps What’s coming next in Part 2: a hands-on formae demo in a real AWS environment Chapters 00:00 – Your IaC is drifting out of orbit 00:29 – Why Terraform & friends are failing modern teams 01:20 – Meet formae: new open source Infrastructure as Code 01:46 – Code-first design, PKL language and no UI lock-in 02:26 – No more state files: reality as the single source of truth 03:14 – Agent-based IaC and asynchronous applies explained 04:08 – How formae fits with Terraform, Pulumi and ClickOps 04:53 – Sponsor break: how Merge Ready built this explainer 05:38 – Core features: full IaC, automatic codification, continuous sync 06:59 – Patch mode vs reconcile mode: controlling blast radius 07:45 – Schema-safe declarative config and fast feedback on mistakes 08:37 – Extensibility, plugins and the formae open source ecosystem 09:23 – Should you sunset Terraform and move to formae? 10:08 – What’s next: upcoming formae live demo (Part 2)
