Inside Terraform's DAG: How Dependency Ordering Really Works

Deep dive into Terraform's dependency graph: DAG construction, implicit vs explicit dependencies, graph walking, and parallel execution.

Terrateam is looking for an OCaml developer for a 3-month contract. Remote, paid, interesting infra problems. DM if interested or know someone who might be.

Terraform state has been a flat file for too long. What if it was a graph? We're exploring that idea with Stategraph

stategraph.dev

#terraform

Stategraph — Terraform without the state file bottleneck

Stategraph replaces Terraform's flat state file with a database-backed dependency graph. Disjoint changes can run in parallel, and state is queryable.

So excited that our Co-Founder and CTO Malcolm Matalka is speaking at @fun-ocaml.com about why Terrateam is absolutely bonkers, no frameworks only libraries. Don't try this at home. #OCaml

Declarative programming keeps code composable and predictable. Recursion, iteration, data structures, and even security when state creeps in all through a pragmatic lens any Ocamler will appreciate.

This is our most frequently asked question in sales calls: how does Terrateam compare to a rock? Finally, we have an in-depth answer.

We just open sourced Terrateam's new UI.

Our old one was barely usable, but customers didn’t pick us for that. They chose us for flexibility and fast support.

Most OSS tools gatekeep UIs for enterprise. We're bootstrapped, so we don’t have to. Real value should be open.

🎉 Excited to announce Malcolm Matalka (from @terrateam.io
) will be speaking at #FUNOCaml 2025 in Warsaw! 🧡🐫

📅 September 15-16, 2025 📍 Warsaw, Poland

"Frameworks: No, Libraries: Yes. Developing a product in OCaml from Scratch" explores how @terrateamio built their infrastructure management platform by creating custom frameworks instead of relying on existing ones.

Learn how OCaml enabled a two-person company to build almost all their own tooling and achieve success! 🚀

At Terrateam we're shipping a lot: new UI, GitLab support, PR summaries, blog posts.

Next week we're taking a break from all AI talk. Fun rabbit hole, but time to lock in and crank out some #OCaml.

Terrateam @terrateam.io · Jun 4

We shared a feedback form in the Terraform Users LinkedIn group.

One response to "What’s stopped you from trying Terrateam?"

"OCaml."

Truth is, it's one of the reasons we move fast and ship safer.

We're writing an RFD about how we write RFDs.

Good decisions come from clear thinking and real discussion. As Terrateam grows, we want a process that supports diversity of thought and makes it safe to speak up.

Contrary to popular belief, it is not difficult to hire for #OCaml. We just recently hired two fantastic engineers and had quite a few resumes come in.

Terrateam is a two-person startup, built in OCaml, competing with HashiCorp. We've bootstrapped it, open-sourced it, and stayed lean.

We just released OpenInfraQuote (oiq), an open source cost estimation tool built with OCaml. It runs in CI, reads Terraform plans and state files, and gives cost estimates from the CLI. No servers. More docs soon.

We love building real tools in OCaml.

I feel so lucky getting to learn Ocaml with the folks at @terrateam.io

Not only is @donalddinkenfelter.bsky.social (cofounder) one of my oldest friends, he is one of the best programmers I've ever known, and I've known at least a bobdyllion

Can't wait to release the tool we've been building

If I designed Ocaml, there's be skateboarders everywhere

val ( :[>-{o ) : 'a -> ('a -> 'b) -> 'b
val ( o}-<]: ) : 'a -> ('a -> 'b) -> 'b

And this would evaluate to true

foo :[>-{o bar :[>-{o baz == baz o}-<]: bar foo

HashiCorp is now part of IBM. We wrote about what we think that means (not much).

They lost their way a while ago. Now they are part of a company that is not exactly known for innovation. Meanwhile, OpenTofu is growing, and Terrateam is on a different path.
