tfui — Interactive Terminal UI for Terraform
Stop reading terraform output in raw text.
k9s for Terraform. Navigate it with ease.
The problem with terraform plan output
200 lines of terraform plan output. Somewhere in there, a database is about to be destroyed. You’re scanning for the word “destroy” like it’s 2005 and you’re grepping production logs by hand.
You find it — on line 847, between two tag updates.
terraform-ui sees what you’d miss.
Terraform Plan Viewer
Navigate changes as a tree. Expand attribute diffs inline. Risk badges surface the critical delete hiding between tag updates.
Every change is classified immediately: [CRITICAL] [HIGH] [medium] [low]. No scanning. No guessing. The dangerous change jumps at you — not the other way around.
Pin Resources, Apply Targeted
Pin the resources you care about. Apply only those — no -target flags to type, no copy-paste mistakes.
One key (space) to pin. One key (a) to apply. The tool handles the rest: replans with your targets, shows you exactly what will happen, asks for confirmation.
Terraform Risk Analysis
Every change classified: critical, high, medium, low. The RDS destroy doesn’t hide between tag updates anymore.
Resource-specific rules: deleting a database is critical. Updating a security group CIDR from 10.0.0.0/8 to 0.0.0.0/0? That’s high. A tag change? Low. You see the breakdown before you do anything irreversible.
Terraform State Browser
Browse, search, inspect. Delete and move with confirmation — not with typos.
Fuzzy search across hundreds of resources. Inspect full attribute JSON. Taint, untaint, import, move — with safety prompts instead of naked CLI commands.
Phantom Change Detection
Terraform says “1 to change” but nothing actually changes. tfui detects cosmetic diffs — null vs absent, array reorder, provider normalization — and marks them.
Stop chasing ghost diffs. Stop second-guessing whether that “update in-place” is real. Phantom detection tells you which changes are noise.
