How Infralyst Works
Three quick steps to go from AWS accounts to reviewable Terraform PRs.
1. Connect your infrastructure
Add the Infralyst Terraform module, install the GitHub App, and map Terraform state to your AWS accounts and repos. Infralyst connects via a read-only IAM role. No agents to install, no write access to your infrastructure.
2. Infralyst finds savings
Infralyst continuously analyzes your AWS resources against conservative, transparent thresholds. No black-box scoring or machine learning. Every check is deterministic with documented rules.
3. Generate a Terraform PR
Pick a recommendation and click Generate PR. An AI agent reads your Terraform repo, writes the change, and opens a pull request. Your team reviews, tests, and merges it like any other change.
Every change is a small, reviewable Terraform diff.

Security, privacy and control
Infralyst is built for teams who care about their AWS accounts and Terraform repos. Here's how we keep it that way.
Read-only AWS access
Infralyst connects via a Terraform-created IAM role with read-only permissions, so it can see resources and utilization without you managing long-lived access keys.
Minimal permissions
We follow the principle of least privilege and only request the AWS APIs needed to analyze usage and propose changes.
PR-only changes
Infralyst never deploys directly to your infrastructure. All changes are delivered as Terraform pull requests in your own repos, and your team reviews, tests and merges them.
Data handled carefully
We focus on infrastructure metadata and usage, not your application data. Data is encrypted in transit and at rest, and access to production systems is strictly limited.
