@hot_town Thank you for using me 😎

SAY HELLO TO MY LITTLE FRIEND

[Vinny @hot_town]

Paid coding courses make their creators rich. Not you.

so I built Open Vibe:
✦ free & open-source - not $299
✦ runs inside your agent - @claudeai, @opencode, etc
✦ the agent tutors as you build
✦ ends with a real SaaS via @opensaas_sh

I built Open SaaS, the #1 free SaaS starter on Github (14k★). Open Vibe is the prequel.

Learn to code as you build a SaaS

This is the way to learn in the AI era:

[Vinny @hot_town]

Most tutorials are boring.

So I built an interactive web dev course for Claude Code.

Claude is your tutor as you build real apps, providing animated diagrams, and explanations.

It's 100% free and open-source, too!

[OpenSaaS.sh @opensaas_sh]

AHHH I'VE BEEN UPDATED 🚨

[Vinny @hot_town]

Open SaaS just got a big update:

- Lazy-loaded pages: smaller bundles, faster loads
- OpenAI SDK v6
- Zod v4
- New AGENTS .md / CLAUDE .md files
- Updated agent skillz
- Improved env var validation
- Improved payments code

We've been building "Rails for JS, but deploy anywhere" for the last 5 years with https://t.co/6lGZ3ZwHrX.

Very cool to see the industry moving towards a full-stack JS experience, esp. from giants like Vite and Evan.

Being fully agnostic is very challenging to build, but we're sure it will be worth it.

[Lei Singha @LeiSingha]

Hi Everyone!

I just built my first SaaS app (https://t.co/frsMOzajbT) in 1 week using @opensaas_sh.
It basically generate ATS compliant resumes and has editor features. It's also my first time launching a product — any advice on how to market it and get my first users?

TIA🙏
