OpenSlides review
A focused, free tool for building animated code slides offline.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenSlides is a free, open-source desktop application for developers, educators, content creators, and technical presenters who want to create animated presentations from source code. Its workflow centers on code-based slide creation, with Magic Move transitions between code states and step-by-step line highlighting. Presenters can use light or dark themes, full-screen mode, autoplay with per-slide timing, and keyboard navigation. OpenSlides runs on Windows, macOS, and Linux and stores projects locally for offline use.
The main strength is its focused animation model for technical material. Magic Move transitions can show changes between code states, while stepped highlights help direct attention through a snippet. Slide search, thumbnails, drag-and-drop slide stacks, and project import and export support organization without moving the workflow into a browser. The Free plan includes the open-source desktop application, offline use, and animated code presentations, so the product is straightforward for individuals who prefer local files and a code-centric presentation process.
That focus also defines its limits. OpenSlides is better suited to technical walkthroughs and code demonstrations than presentations requiring broad design tools or a wider collaboration ecosystem. The published product positioning does not include verified video export, collaboration, or integrations, which may matter for teams sharing work or distributing rendered presentations. Choose OpenSlides if offline storage, open-source software, and animated code slides are priorities. Consider an alternative if you need collaborative editing, connected integrations, or verified video output as part of the presentation workflow.
