OpenFarm is a free and open database and web application for gardening knowledge that was shut down in April 2025 due to lack of maintenance and security concerns. The project's codebase and data are still available on GitHub, and some commenters are interested in reviving or forking the project. OpenFarm aimed to provide a platform for gardeners to share knowledge and find answers to questions about growing plants. The project's shutdown has sparked discussion about the challenges of maintaining open-source projects and the importance of preserving knowledge and data.
