TFLint vs USBImager

TFLint is a local command-line linter for Terraform, with checks supplied by plugins. Its bundled language rules can flag deprecated syntax and unused declarations, while cloud-specific checks look for potential errors in AWS, Azure and GCP configurations, including invalid instance types. It can also enforce best practices and naming conventions. Extend it with plugins, create your own, or write policies in Rego. An optional `--fix` flag can correct issues automatically, and reports can be emitted in default, JSON, Checkstyle, JUnit, compact or SARIF formats. TFLint runs on Linux, macOS and Windows and is free, with no free trial. The project provides a GitHub Action and Docker image; installation options include Homebrew, WinGet and Go. Most files use MPL 2.0, some files in the Terraform package use BUSL 1.1, and release binaries are bound by both licenses. The project recommends verifying release checksums with GitHub CLI artifact attestations and identifies Cosign signatures as deprecated.

USBImager is a free desktop utility for writing disk images to USB drives and creating backups. It reads raw images, compressed formats such as .gz, .bz2, .xz, and .zst, and archives including .zip, .tar, .cpio, and .pax. It can compare a written drive with the source image to verify the result, and create backups in raw or ZStandard compressed format. Images can also be sent to microcontrollers over a serial line. The app is available for Linux, macOS, and Windows, with a minimalist native interface and 18 language options. The maker says it is intended for people who may be uncomfortable with command-line tools, and that it tries to avoid overwriting the system disk. Synchronized writes are intended to ensure data is on disk when progress reaches 100%. The maker describes it as free of advertisements and privacy concerns and GDPR compatible. One stated limit is that xz compression dictionaries larger than 1 gigabyte are unsupported. The app is open source under the MIT license.
