24 alternatives to Subscan - CLI tool for subdomain recon
Subscan is a Go-based CLI tool that helps bug bounty hunters and pentesters with subdomain discovery (passive and brute-force), scoring (HTTP/TLS/CNAME), and misconfig probes (takeovers, open .envs, S3 buckets, etc). Output formats include JSON/CSV/HTML/Markdown. GitHub: https://github.com/omerimzali/subscan Looking for feedback!

Hey HN, we built Subtrace (https://subtrace.dev) to let you see all incoming and outgoing requests in your backend server—like Wireshark, but for Docker containers. It comes with a Chrome DevTools-like interface. Check out this video: https://www.youtube.com/watch?v=OsGa6ZwVxdA, and see our docs for examples: https://docs.subtrace.dev. Subtrace lets you see every request with full payload, headers, status code, and latency details. Tools like Sentry and OpenTelemetry often leave out these crucial details, making prod debugging slow and annoying. Most of the…

I built a Rust-based CLI/terminal UI for inspecting Parquet files—data, metadata, and row-group-level structure—right from the terminal. If someone sent me a Parquet file, I used to open DuckDB or Polars just to see what was inside. Now I can do it with one command. Repo: https://github.com/kaushiksrini/parqeye

Hello! I'm learning Rust and also information security, so what better way to learn than to put a tool together practicing both skills? I've tried to use a couple of different tools for subdomain enumeration (part of the Discovery-party when it comes to penetration testing), but none of them were very fast, even if the DNS resolver I pointed them towards is, so I wrote my own tool that leverages concurrency to check a lot of subdomains, fast! It's written in Rust, main parts being using Tokio and async_channels, and I think it works good enough for a first release. I wanted to get recursive…

Onboard-CLI—a blazing-fast developer tool I built in Go. It uses AST parsing (Tree-sitter) to map out codebase architecture and automatically blocks spaghetti code and bad dependencies locally before you even commit. I heavily optimized the concurrency, so it can parse 50k+ files in under 10 seconds.

Current AI-assisted CLI tools are often part of larger systems and work better on Linux. I built llm-term to address these. It's a Rust-based tool that compiles into a single binary file. You only need to download the binary, add it to your PATH, and configure your OpenAI key to get started. While llm-term offers an option for gpt-4o, it works great with gpt-4o-mini. So it's not costly. I appreciate any feedback or suggestions.
