Show HN: Wiredoor – Securely expose private services

Hacker News - Sat, 04/26/2025 - 11:53am

Hey HN,

I built Wiredoor, an open-source platform to securely expose private HTTP and TCP services to the internet, without opening firewall ports or dealing with complex VPN setups.

Wiredoor uses WireGuard to establish encrypted tunnels and NGINX to proxy traffic to internal services, making it much easier and safer to publish apps from your private network or homelab.

Docs: https://www.wiredoor.net/docs

GitHub: https://github.com/wiredoor/wiredoor

Would love any feedback, questions, or suggestions!

Show HN: Email Sleuth – Find and Verify Emails (Rust CLI)

Hacker News - Sat, 04/26/2025 - 11:53am

I built this because I was tired of paying $99/month for tools like Clearbit and Hunter — and most of them don’t even verify if the email address exists. They just guess.

So I wrote a CLI tool in Rust.

You give it:

A full name (like “Jane Smith”) A domain (like company.com) It:

Generates common email patterns (jane@company.com, jsmith@, etc) Scrapes the company website for any public emails Does an SMTP check (MX + RCPT TO) to verify if the email exists Scores and ranks the candidates Why?

I wanted something fast, private, scriptable, and verifiable — not just “guesses” wrapped in a pretty UI. This has JSON in/out, works well in batch mode, and can run locally or in CI pipelines.

Notes

Port 25 warning: SMTP verification requires outbound port 25 access. Most home ISPs block this. I’m not a networking guy, so maybe there’s a better solution — but I just run it on a GCP VM and it works fine there. Rust has been awesome for this: fast HTTP/S scraping, socket-level control, robust error handling, and painless multithreading. Probably wouldn’t want to write this in Python. It’s open-source (MIT), no trackers, no signup, no web UI. Not sure if this is useful to anyone outside of that weird founder/hacker/recruiter intersection, but figured I’d share.

Would love feedback, issues, feature requests, or just a reality check.

Show HN: Flash-install - a fast, drop-in replacement for npm install

Hacker News - Sat, 04/26/2025 - 11:49am

A fast, drop-in replacement for npm install, focused on drastically speeding up Node.js dependency installation through deterministic caching, parallel operations, and .flashpack archive snapshotting.
