on Hard Mode
Free AI tools. Open source. Own your stack -- or let me build something custom.
You're paying $500/month for tools that barely work together.
Sound familiar? There's a better way.
You're paying for tools you barely use
→ $50/mo here, $100/mo there -- it adds up to thousands per year
Your tools don't talk to each other
→ Manual data entry, CSV exports, and integration nightmares
Locked into monthly subscriptions forever
→ Miss a payment and your whole workflow breaks
One-size-fits-all software that doesn't fit
→ You adapt to the tool instead of the tool adapting to you
No control over your own data
→ Your business lives on someone else's servers, under their rules
Scaling means more SaaS bills
→ More users, more seats, more "enterprise tier" upgrades
What if you owned your entire stack — and it was completely free?

What Clients Are Saying
Real businesses. Real results. Real growth.
We went from 2 purchases a day and $6,000 per month to $100k per month and 100 purchases a day! They literally saved this business.
The launch went wild! Not only did we get a ton of attention, but we sold our first 100 units and did our first $50K of business.
I made $48,000 in my first 6 weeks... Matt and his team are amazing!
We tripled our leads without adding staff. The AI follow-up system alone paid for everything.
WHO'S BUILDING THIS STUFF
Matt Johnston // Builder & Vibe Coder
I'm Matt Johnston.
I spent years in marketing — agencies, consulting, the whole thing. Got really good at strategy. Got really tired of the tools.
Then I discovered vibe coding. Turns out, if you can describe what you want, AI can help you build it. So I started building.
The Bridge (CRM). Banana Code (mobile dev). AssistantOS (AI employee). VibeCanvas (creative). I replaced my entire $500/mo stack with apps I own.
Now I'm open sourcing all of it. Not because I'm a saint — because it's the best way to build a brand and help people at the same time.
Take the tools. Watch the videos. And if you want me to build something custom? I do that too.
Frequently Asked Questions
Everything you need to know about the tools and how to use them.
Are these tools really free?
Yes. MIT licensed. No "free trial" bait-and-switch. Clone the repos, deploy them, modify them. You own the code. No credit card, no signup wall, no catch.
What is vibe coding?
Describe what you want in plain English, and AI helps you build it. Every tool in this arsenal was built that way. You don't need to be a traditional developer -- you just need to know what you want.
Do I need to know how to code?
For basic deployment, no -- most tools have one-click deploy options. For customization, basic comfort with a terminal helps, but AI handles the heavy lifting. That's the whole point of vibe coding.
What's "The Prompt"?
The Prompt is my weekly newsletter. One email, every week. The AI tricks I actually use, what I shipped, and the shortcuts nobody's talking about. No fluff, no courses, no upsells. Just signal.
Can I use these for my business or clients?
Absolutely. MIT license means commercial use is fine. Deploy them for yourself, white-label them for clients, or use them as a starting point for something custom. No restrictions.
What if I need something custom built?
I take on select custom projects -- apps, websites, full-stack builds. Use the inquiry form below to describe what you need, and I'll let you know if it's a fit.
How do I get help if I'm stuck?
Open a GitHub Issue on the specific repo -- I respond to all of them. YouTube tutorials walk through each tool in detail. Community Discord is coming soon for real-time help.
What tech stack are these built with?
Most use React/Next.js for frontend, Supabase for backend, and Vercel for hosting. All modern, all well-documented. Check each repo's README for specific details and deploy instructions.
