DeepDeck - Open-source AI apps you can use, modify, and share

DeepDeck is an MIT-licensed macOS desktop built on DeepSeek Harness. It turns Cordis plugins into apps with their own windows, settings, Workspaces, and Agent Sessions. Use Hacker News Reader or Video Sherlock, ask the agent to modify local source, rebuild and hot-reload the result, then contribute useful changes through Git and PRs. Bring your own Codex or DeepSeek connection. No included model credits. Not an official DeepSeek product.
