DS Anywhere vs MindSpark

DS Anywhere is a free, open-source Nintendo DS emulator that runs in a web browser. To launch software, select or drag an .nds ROM file onto the site; the maker says those files remain on your computer rather than being uploaded. BIOS files can be added in Settings for a firmware boot into the Nintendo DS main menu. Available settings cover controls, personalization, controller input, firmware, and save data. The project uses a melonDS fork compiled to WebAssembly, with a TypeScript bridge and Preact/Vite frontend. Its maker describes the project as a work in progress with unstable or incomplete features and warns about unintended behavior or lost saved data. Browser storage may evict saves, and backup or restoration is not implemented. Controller input works, but changing bindings in the interface is still planned. Cheat codes and multiplayer are future goals; reliable multiplayer may be affected by latency.

MindSpark is an open-source mind-mapping app that runs in a browser or can be self-hosted. Its editor combines an infinite canvas with automatic layouts, keyboard-first editing, drag-and-drop reordering, search, presentation mode, and undo and redo. A Markdown outline and the map canvas stay synchronized as users edit either view. Research tools can fill citation details from Crossref using a DOI and export cited nodes as a references list. Users can compile a map branch into a prompt, estimate its tokens, and run it with their own Anthropic or OpenAI API key. MindSpark imports JSON, OPML, Markdown, GitMind, and MindMeister files, and exports PNG, PDF, JSON, Markdown, Word, and Mermaid. Self-hosted mode stores maps in SQLite and requires Node.js 22 or later; browser mode saves maps as private JSON files in a repository on GitHub, Gitea, Forgejo, or GitLab. The app is free with no feature gates or usage limits and is released under the MIT license.
