Thank you to everyone who joined our "map your TAM from the terminal" session with last week. We built live in the terminal using Claude Code and the MCP. I wrote up the whole thing afterwards. The seven stages, why each one exists, what to do with the list once you have it, and the outreach half we covered at the end. The recording is linked inside. The skill is public too, so you can run it on your closed-won book. You bring your own accounts; the engine does the expansion, scoring, and contact-finding. Comment "TAM" and I'll send you both skill and guide.

So my launch of – the simple, proxy-less AI model cost monitoring software – didn’t generate much response. I said I would build this in public, so here is an update.

All I did was publish the app, make a single post on X, LinkedIn and Show HN. That’s not really any sort of distribution effort needed for an app. So I will continue to get the word out regarding Costbase on Reddit, and other places, as well as engaging with X users who have problem with AI cost. (If you guys have ideas, lmk) It’s just a small app, a side project, so I won’t put too much time marketing this before calling it quit. Pre-AI, I’ve always spent so much effort building an app that I don’t have any time left for marketing (I also run an ERP consultancy). Now, building is pretty much automated, so th

500+ Hugging Face models through a single free API no credit card just an email signup 😳 launched on July 3 as a unified gateway for Hugging Face models one API key one endpoint 500+ models what you get for $0: • 500+ open-source models through an OpenAI-compatible API • no separate API keys for different providers • works with Cursor, Claude Code, Hermes, OpenCode, and anything that supports a custom base URL • email signup only setup takes about 2 minutes: 1. Go to 2. Sign up with your email 3. Generate an API key 4. Set your base URL to 5. Choose any model from the catalog and start building a few things worth knowing: • is a third-party gateway, not an official Hugging Face product • the free tier is rate-limited, but the exact limits haven't been published yet • i wouldn't build production apps that depend entirely on a free aggregator what i like is the simplicity instead
