6 Best Open Source V0 Alternatives: Complete 2025 Guide

🚀 The Problem with V0, Bolt.new, and Lovable: Vendor Lock-In

💡 Quick Start: Looking for open-source alternatives to V0, Bolt.new, or Lovable? This guide compares 6 production-ready options including Bolt.diy, Libra AI, Dyad, December, Open-Lovable, and OpenBolt.dev—all offering complete control without vendor lock-in.

As AI-powered app builders like V0, Bolt.new, and Lovable gain popularity, developers face a critical challenge: vendor lock-in. These platforms offer incredible speed for prototyping, but when you're ready to deploy to production, you're stuck with their infrastructure, pricing models, and limitations.

The core problem: Most AI app builders are closed-source SaaS platforms that:

  • ❌ Lock you into their hosting infrastructure
  • ❌ Charge per generation or monthly subscriptions
  • ❌ Limit customization and self-hosting options
  • ❌ Don't provide access to the underlying codebase

This is where open-source alternatives shine. In this comprehensive guide, we'll explore 6 production-ready open-source alternatives to V0, Bolt.new, and Lovable that give you complete control over your AI application development workflow.
