I have rebuilt the Markdown to PDF converter on You paste your text or Markdown, you get a properly typeset PDF back, and your AI agent can do the same over MCP or a plain API call. No sign up, no key, free. Had built this a long time back as a fairly basic thing and then left it alone, and over the last few weeks I could see a rise in traffic. Took a fresh look and found that lot of it was not rendering. Headings below a certain level were being dropped, nested lists were coming out flat, and code blocks were losing their formatting. What is there now: - Page breaks where you want them, using :::pagebreak::: on a line by itself - Tables, nested lists, task lists and code blocks all render properly - Greek letters, maths symbols, arrows and the rupee sign come out right - Emoji and symbols do not break the render - Plain dot txt files keep their line breaks Live tool at API & MCP docs (humans): API & MCP docs (AI)

I got tired of paying so much just to have analytics for dynamic QR codes, so I built my own. lets you create dynamic QR codes for free, customize them however you want, and gives you 30 days of analytics without adding a watermark. What else would make it the best QR code generator?

A lot of things actually: 1. (qrcode generator - $120mrr) 2. (analytics soon + monitoring) 3. 4. (~10k visitors)

If you're a developer, you've probably experienced this: You need a realistic invoice for testing, and suddenly you're creating an account for a tool you'll only use once. I wondered if there was a simpler approach, so I am working on one for myself.
