Pastedown.space: Temporary Markdown Sharing for the LLM Era

Pastedown.space is a small pastebin I built for sharing Markdown snippets with a team, a client, or whoever needs them. You paste your text, get a unique link, and share it. Three days later the paste expires and the link stops working.

I built it for two reasons. Markdown is a good format for readable, portable text—READMEs, code walkthroughs, structured notes. And with Large Language Models in the mix, I'm handling more Markdown than ever: prompts, docs, training snippets all tend to be well-structured Markdown. Pastedown.space is just a quick way to drop that somewhere and let it expire on its own.

The interface is deliberately minimal. You paste your content, hit Create Paste, and get a unique URL that expires in exactly 72 hours. It works for code snippets, meeting notes, or quick documentation you don't want to store permanently.

Across Devices

Pastedown.space is responsive, so it works on a laptop, tablet, or phone without pinching or zooming. The Markdown looks the same on a small screen as it does on a large one.

The Stack

Here's what it's built with:

• NextJS: server-rendered frontend.
• ShadCN: UI components.
• MongoDB: backend storage, with pastes set to live for 3 days.
• Vercel: deployment.
• GoDaddy: domain.

Why 3 days? Not every share needs to stick around forever. Sometimes you just want a digital sticky note—drop the Markdown, send the link, and let it disappear once it's done its job.

If you use Markdown in your workflow, I'd be curious how—and what role you see it playing as more work shifts to LLMs. Drop a comment below or ping me on X.
