","body":"Hey YC, we are [Paul](https://www.linkedin.com/in/hey-paul/) and [James](https://www.linkedin.com/in/jamesdreamcrafters/), cofounders at [OpenBuilder](https://www.linkedin.com/company/openbuilder/). 👋\n\n### **TL;DR**\n\n**OpenBuilder is the open source alternative to Lovable — where non-technical builders actually finish their projects.**\n\nhttps://youtu.be/yVgGsf3nN44\n\n### 🔴 The Problem: vibe coding is a slot machine\n\n**Pay for credits, pull the lever, pray things work.**\n\nVibe coding has brought millions of non-technical users into building. But over 80% can't finish what they start. The magic fades as projects grow — bugs multiply, progress stalls, and builders get stuck\n\nThree core problems block non-technical builders:\n\n1. too expensive — costs spiral out of control\n2. too many bugs — issues pile up faster than they can fix\n3. getting help is nearly impossible — especially on closed platforms where backend/integration code is hidden\n\n![uploaded image](/media/?type=post\u0026id=95336\u0026key=user_uploads/690363/7a1df823-cdcf-4647-a6c4-6585daa3c4cf)\n\n### 🟢 The Solution:\n\n### At OpenBuilder, users build for free on a truly open platform, and pay to get unstuck from a real dev.\n\n**Vibe code without limits.**\n\nOpenBuilder uses optimized open-source models to match Claude Sonnet 4's performance—making building completely free.\n\n![uploaded image](/media/?type=post\u0026id=95336\u0026key=user_uploads/690363/cf0cf66d-a3da-4ef2-aa68-e1bf86fcd09b)\n\n**Pay to get unstuck.**\n\nOur interactive debugger helps you first. If that doesn't solve it, you can escalate to a real developer who already has your project context.\n\n![uploaded image](/media/?type=post\u0026id=95336\u0026key=user_uploads/690363/1be25b13-5159-4254-acd8-3ff15d2e8c9a)\n\n**Truly open platform, no lock-in.**\n\nOpenBuilder is truly open. It's built on VS Code, so you can swap in your own AI model, try different agents, or export your entire codebase anytime.\n\n### Team\n\nPaul \u0026 James have known each other for over 10 years. They met while studying CS at the University of Waterloo.\n\nBefore OpenBuilder, they built EasyCode — a popular context-aware coding assistant installed by over 1.5M developers between VS Code and JetBrains. Now they are applying similar technologies to help non-technical builders turn their ideas into reality.\n\n![uploaded image](/media/?type=post\u0026id=95336\u0026key=user_uploads/690363/c8743abd-9d52-49d6-bc36-2d17fe05fad7)\n\n### Ask\n\n**We're making building accessible to everyone. Non-technical founders shouldn't just start projects—they should finish and ship them.**\n\nHere is how you can help. 🙂\n\n* Follow us on [X](https://x.com/theopenbuilder) and [LinkedIn](https://www.linkedin.com/company/openbuilder/) and share the launch!\n* We're open sourcing our codebase soon.
