OSDHack 2026

OSDHack 2026 Build AI that runs closer to the user, faster, lighter, more private, and open source. OSDHack 2026 is an online open-source hackathon by Open Source Developers Community (OSDC) , built around the theme On Device AI . Your challenge: build something where the core AI feature runs locally on a phone, laptop, desktop, browser, edge device, or embedded system. Think offline-first AI, privacy-friendly tools, browser-based AI, lightweight local models, edge AI, embedded AI, and creative open-source projects that do not depend fully on cloud AI APIs for the main AI functionality. Our Sponsors Theme: On Device AI Your project should focus on AI that runs locally. You can build around: Local AI models Browser-based AI Mobile on-device AI Desktop AI tools Edge or embedded AI Offline-first AI apps Privacy-focused AI utilities Lightweight local inference Cloud services are allowed for support features like hosting, authentication, storage, databases, or deployment. The main AI feature, however, should run on-device, locally, in-browser, on edge, or on embedded hardware. In short: cloud support is fine, but the AI magic should happen locally.
