I have rebuilt MocharyBot. This is a chatbot based on the @mattmochary's Method Curriculum. I built the first version using vanilla JavaScript, Python (FastAPI), plus Pinecone. I've rebuilt it using Next.js, and Supabase as the vector store. Using @langchain, of course. On my first try, I used LangServe for the chat service, but I ended up using only Next.js, just because I didn't want to maintain too many things. Would be any of you interested in the code? Or maybe you are interested in using LangServe as the backend for a JS frontend? This took me a while to figure out, as I'm not a JS guy 🤷

Finally, I've just launched TokenTrackerSh! 🚀 40 days have passed since I had the initial idea. My plan was to release something in a couple of weeks, and 13 days after having the idea and testing it with a Python PoC, I launched the landing page with a waiting list. That was possible thanks to the use of a SaaS boilerplate: Shipped, from @ikoichi. Some days later, I posted a blog to have something valuable to share and start working on SEO. Then I started finishing the app. I built the backend of the service using my loved and trusted Python 🐍 The frontend side, authentication, dashboard, payments... Everything was super easy to put together thanks to the Shipped boilerplate. And finally, the full app is now LIVE. TokenTrackerSh allows you to easily track your low-cap crypto tokens directly in Google Sheets. There is a 7-day free trial to start (no credit card required), and then you can purchase a one-time payment lifetime access. No subscriptions (for the moment). Now, there are some rough edges that I want to work on, but the service works seamlessly. But before I start working on improvements and new features, I need to achieve some product-market fit (PMF). My plan is to share it with some people who would be interested in the app, so they can test it and give me some feedback (which I'm already getting), and after some fixes, post it on some micro-launch sites. If you're interested in crypto investments and looking for a simple way to track your portfolio, I’d love for you to try the free trial. Your honest feedback would be greatly appreciated 😊 🔗 Link in the next tweet. #buildinpublic
