Free Nest.js - 22 Free AI tools

I needed a chatbot for a simple but repetitive task, and I got it in a few minutes, without knowing anything of coding. It made it in Python. Truly satisfied. :-)

I asked it to generate simple and more complicated code, from scratch or fixing. Planning on trying it out more in the future, as it could be of great help.

This is cool, I can do code on the left side, and the right side can give me advice on my code. Spares me a lot of headaches and I can do it anywhere with ease

So many SaaS offerings need rethought to be AI/agent first. And the new thinking really start with the simplicity and appropriate costs needed for the "user" being an agent. tny.dev is really a master class in this new thought process. If you need link shortening, it's completely solved here. I've been using it with Claude Desktop, and Claude just "gets" this MCP server, and its free at the relatively infrequent rate I use it. The analytics are awesome and simple to understand. They are the key feature for me.
