Our verdict on 900Slides

900Slides is a free, open-source desktop presentation editor for creating, editing, presenting, and exporting slide decks. It is aimed at classrooms, small businesses, researchers, public services, and community organizers who work on Windows, macOS, or Linux and want local presentation workflows. The application runs without an account, subscription, telemetry, or constant internet access, while supporting PPTX import, editing, and saving.

Pricing is straightforward: the Free plan includes the desktop presentation editor, PPTX editing and saving, offline operation, and an Apache-2.0 license. It also covers a broad set of everyday authoring needs, including rich text formatting, links, headings, code blocks, images, geometric shapes, tables, charts, templates, slide sections, speaker notes, and find-and-replace. Offline spell-check, crash recovery, comments, and accessibility checks add practical safeguards for preparing decks locally.

The standout fit is offline presentation work rather than connected team production. Presenter mode provides notes, a timer, next-slide preview, and dual-display output, while animations, transitions, Magic Move, and stepped code highlighting support more structured delivery. SVG, PNG, and PDF export extend the desktop workflow beyond PPTX. However, users who need real-time collaboration, mobile or web clients, or AI assistance should choose a different presentation tool. 900Slides suits individuals and small groups prioritizing local control and desktop PPTX editing, while its pre-1.0 status makes it less suitable for teams that require completed release and installation processes.
