Ofrenda: An altar where dead open-source repos come back to talk

Ofrenda is an online altar dedicated to commemorating deceased open-source software projects. By inputting the URL of an abandoned GitHub repository, the tool retrieves the repository's complete history, including the date it was created, when it ceased development, the final commit message, and who made the most contributions. If GitHub is accessible, Ofrenda also fetches data such as the number of stars, forks, and whether the project was archived.

Using a Gemma 3 model, the software generates an epitaph, an obituary, and three key contributions left behind by the now-defunct project, all derived from its original README and documentation. A floating 3D sugar skull, adorned with marigolds and styled like a calavera, serves as the digital ghost representing the repository. Users can interact with the ghost, posing questions in either English or Spanish, which the ghost responds to in the first person, referencing its own README and associated documentation. The ghost's animated jaw movements accompany its speech.

The project aims to preserve the legacy of software that has passed away, allowing its history to be revisited and remembered. The entire operation takes place locally, ensuring no sensitive data leaves the user's computer. No internet connection is required, as the software runs entirely on the user's machine using open-weight models like Gemma 3 and EmbeddingGemma. The setup process is straightforward, requiring just a few commands to install the necessary models and clone the repository.

Ofrenda was developed as part of the DEV Hacktoberfest Open-Source AI Challenge, focusing on the theme of "Ghost in the Machine," where the ghost embodies the machine's own history. The software can be accessed and explored via the provided link, offering a unique and interactive way to pay tribute to open-source projects that have contributed to the programming world but have since disappeared.
