Don't know about vercel but a website can have and only have its frontend vibe-coded, and backend not vibe coded but hosted on railway.

Free online tools for image compression, PDF merging, and document handling without account creation.

Literally guyss u need to check this 🤯 Hey guys, I was getting really annoyed with all those "free" online tools that compress images or merge PDFs but then force you to create an account or pay a premium fee to download your file. Also, uploading sensitive documents to random servers always felt sketchy to me. So, I built a collection of 9 web tools that process everything 100% locally in your browser. No data is ever uploaded to a server, there are no signups, and it's completely free.

Understand code flow and app connections before asking AI to help modify your app.

Thanks for the feedback; I’m open to anything.

Create and export flowcharts, sequence diagrams, ERDs, and other Mermaid diagrams online.

I've been slowly adding some new free tools to Moxie Docs (partly for SEO, partly to illustrate some of our feature sets before any commitment) for some reason this mermaid editor one blew up on Google rankings so I figured I'd share in case people find it useful! We also have ADR, AGENTS.md, LLMs, and a few other free tools.

AI tool that asks clarifying questions and generates verified specifications for coding agents.
jayaprabhakar · HN
I've been building an open source formal methods system (fizzbee.io) for the past few years. Today I'm launching a new app built on the same technology. It performs requirements engineering using formal verification to uncover gaps and produce precise instructions for your coding agents to follow. When given a prompt, it - asks high signal follow-up questions - converts to formal spec and identifies complex requirements gaps - generates validation scenario At the end, it produces a specification document that can be shared with coding agents. In my trials on various projects, it produces working code in fewer iterations. Please give it a try and share your feedback. https://fizzbee.ai/ You can also look at a sample project. https://fizzbee.ai/projects/94bf2869-97a1-445c-8f5d-4445848b...

Not a direct answer but the guys at Exercism (non-profit that publishes really good and free programming language self-study courses) recently launched a separate site to teach junior programmers both vibe coding and software engineering fundamentals.

Practice coding interviews, system design, and code review with an AI coach instead of a judge.

@UK_Daniel_Card I made something similar https://t.co/HCVGlFb8hF. Its completely vibe coded but it is supposed to be a vibe project. Been making it for about 6 months now. Feel fre
