Hey everyone I'm getting ready to launch Tessar and wanted to share it here first.
The short version: you describe a system in plain English ("a subscription invoicing app, ~50k users, GST-compliant, India + US") and Tessar writes a complete cloud architecture in a few minutes components, diagrams, a monthly cost estimate, scored risks, and a roadmap. It can also generate a few competing designs from the same brief and put them side-by-side so you can see the trade-offs (cheaper here, faster there, more lock-in over there) instead of committing to the first idea that sounds reasonable.
I built it because I was tired of losing an afternoon to a blank page every time I started something new.
There's a full sample report you can look at without signing up: https://tessar.dev/r/6rAnqSapFfg
Describe your system in plain English and Tessar writes a full cloud architecture in ~3 min: components, diagrams, monthly cost, scored risks, and a roadmap. It can even generate 3–4 competing designs side-by-side. AWS/GCP/Azure. First design free.
