Archimyst

You describe the system you want to build, and Archimyst returns a backend architecture you can inspect, stress and fix before anything is deployed.

Archimyst is an AI platform for designing, simulating and validating production system architectures.

You can lay out components from AWS, GCP and Azure, then run stress tests and inject failures without writing any code.

When the design has a flaw, such as a database that needs sharding, Archimyst flags it and suggests a fix.

The tool also connects live to Cursor and VSCode, so the coding assistant in your editor works from the architecture you actually drew rather than guessing at it.

That is the part most useful if you already generate code with AI and want it to stay consistent with the design.

The catch is the paid tiers.

Advanced models such as Claude Opus, export to Terraform and Kubernetes, and unlimited use all sit behind a subscription.

A Teams plan for collaboration is marked as coming soon, so for now it suits individual use better.
