Loading

from datasets import load_dataset

ds = load_dataset("twangodev/devpost-hacks")                    # all hackathons
ds = load_dataset("twangodev/devpost-hacks", "treehacks-2026")  # one hackathon

Sources & licensing

This dataset aggregates content from two upstream sources, neither of which has a single uniform license:

1. Devpost project pages - Project text (title, tagline, description, links, results) is authored by the participating teams. We include this content here under a fair-use / research-use rationale.
2. README files: Each README inherits the license of its repository.

Because of (2) in particular, we cannot apply a uniform open license to this dataset.

Takedown & Removal Requests

If you are the author of a project (or a maintainer of a linked repo) and would like your content removed from this dataset, email contact@twango.dev with the project URL or repo slug. We will remove it from the next release.
