Inspiration More and more people is developing software. Trillions of lines of code per week and 90% of it is repetitive and insecure. AI agents often rebuild features like login screens, shopping carts and booking calendars from scratch, even though reliable open-source solutions already exist. Developed for decades by engineers. High-quality and security. We built YES IF for Builders to help agents reuse that work and focus on the code that connects it. How we built it YES IF is a free, open library of verified software. Each component is documented, tested, security-scanned and licence-checked. A small open model interprets the request, a decision engine selects the components, and the agent writes the missing glue. The finished app is then verified in a sandbox. The library currently includes 171 components and 11 complete use cases. In our booking-agent comparison, Claude Code with YES IF was 13 times cheaper and over 10 times faster than Claude Code alone. What we learned Reviewing beta requests showed that our safety checks were rejecting things the library could already build, including some homepage examples. We changed the process to show users which requirements are backed by tests before building. We also expanded the library based on requests, adding reminders, payments, mailbox agents and screen recording, then followed up with users about what was supported and what was still missing. Challenges We dealt with full disks, a lost demo and conflicting product versions. These issues pushed us to improve deployment and recovery processes, alongside the product itself.
What's next for YES INTELLIGENT LIBRARY
In the music industry, Spotify appeared. In content, Netflix. The AI era is bringing the same step for software. Now with agents and reverse engineering AI it does not make sense to continue paying for proprietary software. We see this library as a first step to be the world provider to any existing software. One subscription to access them all. Enhanced with AI and agentic capabilities.
