The design is never written down
It exists as a mix of console state, Terraform, and the memory of whoever made the last change.
Agentic DevOps
Design, build, and run your infrastructure from one platform
Agentic DevOps for multi-cloud infrastructure.
Connect your repository. ArchitectureOS learns how your application works, proposes up to three infrastructure designs with the tradeoffs named and the running cost estimated, then generates, deploys and maintains the Terraform across AWS and GCP.

The problem
Infrastructure Gets Decided, Not Designed
Most teams provision infrastructure reactively. A service needs a database, so one appears. Latency becomes a problem, so a cache is added. No single decision is wrong — but nobody chose the architecture, so nobody can explain it, price it, or change it safely.
Cost is discovered, not planned
You learn what the architecture costs from the invoice, months after the decisions were made.
Lock-in is accidental
Provider-specific choices accumulate one at a time, until moving anything becomes impractical.
There is no architect
The decisions a solutions architect would make are made by whoever happens to be on call.
Deployment is a leap
Infrastructure changes are applied without knowing the cost, or the blast radius, in advance.
The reasoning is tacit
Why the infrastructure looks the way it does lives in a few people's heads, and leaves when they do.
How it works
From Repository to Running Infrastructure
Four phases. The last one never stops.
- 01
Understand
Connect your repository. ArchitectureOS reads the application and asks about what it cannot infer.
- 01Connect your application repository
- 02Capture system and functional requirements through clarifying questions
- 02
Design
Up to three infrastructure designs, each with the tradeoffs named and the running cost estimated.
- 01Propose up to three designs across AWS and GCP, with tradeoffs, cost estimates and architecture diagrams
- 02You select the design that fits
- 03
Build and validate
Terraform for a test environment, stood up at small scale before anything reaches production.
- 01Generate Terraform for a test environment
- 02Add environment variables, held in your cloud's secret manager
- 03Stand up a small-scale environment to prove the workflow
- 04Generate production Terraform only after you approve
- 04
Operate
Deploy, then keep the design and the Terraform current as the system changes.
- 01Deploy the production build
- 02Continuously track architecture status and update the design and Terraform as the system evolves
Two ways in
Start Where You Are
Most teams arrive with something already running. You do not need a greenfield project or a clean slate to begin.
A new application
Connect the repository and start from a clean design. ArchitectureOS works from the application outward, so the infrastructure is derived from what your system actually needs.
Infrastructure you already run
Start from your Terraform or CDK. We build the design from what exists, so the next change is made against a model rather than a guess.
No infrastructure as code
If none exists, we assess the running system and produce the documentation for it. From that point on, the architecture is traceable.
Multi-cloud
Multi-Cloud, From the Start
Provider choice should follow from the architecture, not from whichever console was open when the decision was made.
One control plane
Across your providers, so where a service runs is a design decision rather than an accident.
AWS and GCP first
Both supported from the start, with Azure to follow as access expands.
Portable by design
We favour managed services that exist on more than one provider. Where a service does not, we name the lock-in explicitly instead of hiding it.
Your existing infrastructure counts
What you already run is read and understood, so new infrastructure is designed alongside it rather than in isolation.
Cost is a design input. Every design states what it will cost to run before you build it.
Trust and control
Access You Grant, Changes You Approve
A platform that provisions infrastructure asks for more than a dashboard does. These are the rules we design to.
Read-only to begin
Write access is granted explicitly, scoped to what a step requires, and revocable at any time.
Production is gated
Nothing reaches production without your approval. Test environments can be created on demand and torn down.
Your secrets stay in your cloud
Environment variables are held in your provider's secret manager. They never persist on our platform.
You own the output
Infrastructure is delivered as Terraform in your accounts, under your own review and version control.

Compliance Readiness Is an Architecture Problem
Security reviews fail on manual architecture validation and missing evidence, not on missing policy. A maintained model turns evidence into a query.

The Architect Your Team Doesn't Have
We are working closely with a small number of teams to define how infrastructure gets designed, deployed and maintained. Design partners shape what we build first.
What partners receive
- Direct influence on the roadmap
- Founder access
- Early product access
- Preferred pricing
We are looking for teams running real production infrastructure — a Terraform estate, more than one environment, and architecture decisions that currently rest with one or two people.

About
Built by Engineers Who Have Operated at Scale
ArchitectureOS is built by engineers who have designed, deployed and operated production infrastructure. Every problem on this page is one we hit first-hand, repeatedly, and found no durable answer for.
AWS infrastructure
Designing, provisioning and operating production workloads on AWS.
Large-scale distributed systems
Building and running systems where partial failure is the normal case.
Platform engineering
Owning the pipelines, tooling and guardrails that other engineers build on.
Cloud networking
VPC design, routing, service meshes, and the debugging that follows.
Startup execution
Shipping products from first commit through to paying customers.
Building in the open
We publish our thinking on architecture drift and dependency mapping as we go.

Questions We Get Asked
Is this another AI Terraform generator?
No. Terraform is the output, not the product. The work is understanding the application, choosing between designs that fit it, and keeping the result correct as the system changes.
Does it replace Terraform?
No. It writes the Terraform, and you keep it. Your existing tooling and workflows stay where they are.
What access does it need?
Read-only to begin. Write access is granted explicitly, scoped to what a step requires, and revocable — you can remove it and we lose access.
Where are my secrets stored?
In your cloud provider's secret manager. Environment variables never persist on our platform.
Can it change production without me?
No. Production changes require your approval. Test environments can be created on demand, and torn down.
Which cloud providers are supported?
AWS and GCP first, with Azure to follow. Access is opening in stages with design partners.
I already have infrastructure. Where do I start?
From your Terraform or CDK. If you have no infrastructure as code at all, we assess the running system and produce the documentation, so everything is traceable from that point on.
Who is this for?
Teams that have to make architecture decisions and also carry the pager — usually without a dedicated infrastructure or platform function. Early access is opening with a small number of design partners.

Request Early Access
Tell us about the infrastructure you run today. Early access is opening in stages, and design partner slots are limited.
What happens next
- 01We read every submission and reply personally, usually within a few days.
- 02We ask how your infrastructure is designed today, and where the decisions actually get made.
- 03If it is a fit, we open early access or set up a design partner conversation.
