knip
✂️ Find unused files, dependencies and exports in your JavaScript and TypeScript projects. Knip it before you ship it!
Project mention: I built a zero-dep CLI that finds unused dependencies — and is wrong less often than depcheck | dev.to | 2026-06-11The classic answer was depcheck. I reached for it for years — until I noticed it got archived in 2025 with a long tail of open false-positive bugs. And those false positives are the whole problem: a tool that tells you react is unused (it isn't, you're just on the new JSX transform) teaches you to ignore it. The successor, knip, is genuinely great — but it's a ~150-plugin tool built for big codebases, and sometimes you just want a five-second answer to "what can I delete right now?"

Also in this issue: Matt Nigh analyzed 2,500+ repositories to figure out what makes AGENTS.md files actually useful (spoiler: most aren't), browser fingerprinting via favicon is both creepy and clever, PrinceJS lands in the top 3 performance benchmarks despite being "the smallest backend framework ever," and privacy fans get Ackee for self-hosted analytics. Ultracite brings zero-config linting with opinions baked in, and zerobyte automates backups for self-hosters who want to set it and forget it.

docker-compose-linter
A command-line tool for validating and enforcing best practices in Docker Compose files.
What bugged me was the asymmetry. Kubernetes and Terraform have a deep bench of scanners: Checkov, Trivy, kube-bench, Kubescape. Compose is an afterthought in most of them. The Compose-specific tools I found solved adjacent problems instead. Hadolint lints Dockerfiles, not Compose files. dclint checks Compose structure and style, not security.
