I Built a Chrome Extension to Reply to LinkedIn Spam

If you're on LinkedIn, you know the drill. Every day, a fresh batch of DMs from people who "just want 10 minutes" but mean 30. People who "noticed your profile" but clearly didn't read it. People who open with "Hi [FIRST_NAME]," because their automation tool failed.

I got tired of staring at these messages, trying to decide between ignoring them (guilt), writing a polite decline (effort), or just closing the tab entirely (avoidance).

So I built nogodno.

Three buttons. That's it.

nogodno adds three pill-shaped buttons above the message input in LinkedIn DMs:

Button	For when...
👎	No words needed
NO	You want to be clear
GOD PLEASE NO	They asked for "10 minutes" but mean 30

Click a button → message typed → message sent. Done.

Why not just ignore them?

Because ignoring feels rude. And writing a personalized "thanks but no thanks" to every recruiter, agency, and SaaS founder who mass-DMs you is a waste of your finite energy on earth.

nogodno sits in the sweet spot between ghosting and effort. It's honest, it's fast, and it communicates exactly what you mean.

How it works

• Manifest V3: modern Chrome extension standard
• Runs only on linkedin.com/messaging
• No tracking, no analytics, no external API calls
• No permissions beyond accessing the LinkedIn messaging page

It literally does one thing: inject three buttons that type and send a reply for you. That's the entire codebase.

Install it

The extension is open source. You can install it in 30 seconds:

1. Clone or download the repo from github.com/laifehacker/nogodno
2. Go to chrome://extensions/
3. Enable Developer Mode
4. Click Load unpacked and select the folder
5. Open LinkedIn messaging and enjoy

The real lesson

This extension took about an hour to build. It's 150 lines of JavaScript, some CSS, and a manifest file. No framework, no build step, no dependencies.

Sometimes the most useful tools are the smallest ones. Not every problem needs an AI agent, a SaaS product, or a 12-week roadmap. Sometimes you just need three buttons and the courage to say no.
