Arctic Shift is an 🏷️#open-source project by Arthur Heitmann that makes large-scale 📝Reddit data available for researchers, 📝Moderators, and developers through bulk dumps, an API, and a web interface.
The project supports processing of compressed Reddit data formats using helper scripts for efficient handling of multi-gigabyte archives. The API enables programmatic access to historical posts, comments, and user activity without scraping — important since Reddit's tightening API policies have made independent data collection harder for non-commercial users. The web interface offers a lightweight search layer over the same archive for users who don't need bulk access.
A removal-request mechanism is built into the platform, allowing users to request removal of their own content from the archive. This governance layer addresses an often-underappreciated dimension of large-scale social-data hosting and distinguishes Arctic Shift from purely scraped datasets that bypass user consent entirely.

Arctic Shift aligns with the kind of foundational tech we build at a venture studio — bulk dumps for deep analytics, API endpoints for rapid prototyping, and a deliberate governance posture on removal requests. A strong building block for anyone exploring social-data research, moderation tooling, or community-insight verticals.
