DeckCraft vs PowerPoint: A Free, Open-Source Presentation App Reads .pptx

DeckCraft vs PowerPoint is the smallest gap in this series on paper and the youngest project in practice. The DeckCraft repository was created on 7 October 2026, and the README already describes slide masters, 150 preset shapes, animations including Morph, presenter view and native .pptx reading and writing. It also says DeckCraft is in early development, heading for a first alpha.

What DeckCraft is

DeckCraft is the presentation app of the ArtCraft family, covered together with WordCraft and GridCraft in the Crafting Apps guide. It is MIT or Apache-2.0 licensed and native on macOS, Windows, Linux and FreeBSD, with a browser version. Every action is a command, with more than 200 commands that the interface, a command-line tool, a JSON control channel and an MCP server share.

Microsoft PowerPoint is Microsoft's closed-source presentation program, part of Microsoft 365 and sold in other editions, with the largest set of templates, add-ins and presenter features.

What the README lists as working

Building decks. Slide masters and eleven layouts with placeholders that inherit position and formatting, eight original themes with colour and font schemes, sections, notes, comments, headers and footers and custom slide sizes.

Drawing. More than 150 preset shapes with adjust handles, connectors that stay attached to shapes, freeform, curve and scribble tools, shape merging (union, combine, fragment, intersect, subtract), gradient, picture and pattern fills, dashed outlines with arrowheads, and shadow, glow, soft-edge and reflection effects.

Text. In-place editing with full font and paragraph formatting, bullets and numbering, columns, autofit, vertical text, fields and hyperlinks.

Content. Pictures with crop and corrections, styled tables, charts, SmartArt basics, and audio and video in common formats.

Presenting. Transitions including Morph, entrance, emphasis, exit and motion-path animations, builds by paragraph, a full-screen show, presenter view, pen, rehearse timings and media playback.

Files. Open and save .pptx, export PDF (slides, notes pages, handouts), PNG, JPEG and outlines, plus AutoRecover for unsaved work.

The shipped themes are original rather than copies of Microsoft's, which affects what a converted deck looks like. If your organisation has a corporate template in .potx or .pptx, test it first.

The numbers, with context

DeckCraft covers about 79 percent of PowerPoint's features by breadth and 93 percent of the core ones, in the project's own count, and is roughly 80 percent of the way to a first alpha. The first figure is a feature-by-feature scorecard that the repository publishes. The second is a project-management estimate of the alpha checklist. Neither is a measure of how faithfully an existing deck renders.

That fidelity question is the one that decides adoption. Decks made by other people contain custom fonts, embedded media, SmartArt, animations and slide-master quirks, and every one of those is a place where a young implementation can differ. A realistic test is to open five of your own real decks and compare them slide by slide.

What to check before relying on it

• SmartArt. Listed as "basics", so complex diagrams may not match.
• Add-ins and macros. Not described.
• Co-authoring. The README does not describe shared real-time editing, which PowerPoint and Google Slides offer through their cloud services.
• Fonts. The README says fonts come from the craft-fonts package, and without it DeckCraft uses your system fonts, which can change layout.
• Maturity. It has not shipped an alpha yet.

Working from the command line

DeckCraft's README shows a command-line workflow that is rare among presentation programs. One command renders the sample deck, all slides, to image files. Another lists the available commands under a prefix such as format. A third adds a new slide with a chosen layout and title and saves the result in the native .deckcraft format. A fourth starts an MCP server, either headless or connected to the running app through a control port.

Because every action is a command with a stable identifier and there are more than 200 of them, the same operations are available to people, scripts and assistants. That suits generated decks such as weekly reports, where a script fills a template with data and exports a PDF.

Fonts come from the shared craft-fonts package when it sits next to the repository. Without it, DeckCraft uses system fonts, which can alter text fitting on slides that were designed with a specific font.

Native format and exchange

DeckCraft saves in its own .deckcraft format and opens and saves .pptx. Export covers PDF for slides, notes pages and handouts with selectable text, as well as PNG, JPEG and outlines. AutoRecover keeps unsaved work.

Exchange fidelity is the question that decides adoption. A deck's visible result depends on theme fonts, slide masters, placeholders, animations and embedded media, and each of these is a point where two implementations can diverge. DeckCraft's own themes are original, so a deck designed with a corporate theme depends on how well the theme and layouts survive the import.

A checklist for testing decks

1. A simple text deck with the company template, to check masters, fonts and placeholders.
2. A deck with charts and tables, comparing values, axes, styles and number formats.
3. A deck with shapes and connectors, to see if connectors stay attached after editing.
4. A deck with animations and transitions, including Morph.
5. A deck with embedded audio and video in the formats you use.
6. Presenter view on your real projector or screen setup, with notes and timings.
7. A PDF export, checked for selectable text and correct page size.

If your decks pass these checks, DeckCraft can already handle ordinary presentations. If they fail on a template or animation, record which feature failed. The project is heading for a first alpha and values this kind of report.

Cost, licence and ownership

DeckCraft is free and released under MIT or Apache-2.0, and the project's own themes and assets are original or openly licensed with attribution. You can run it on any machine and give copies to colleagues without licence counts.

PowerPoint's value lies partly outside the program: templates from brand teams, stock imagery and icons, designer add-ins and presentation coaching tools. None of that comes with DeckCraft, although anything saved as .pptx should open in it in principle. Plan for a transition period where the brand template still lives in PowerPoint and the speaker uses DeckCraft only for delivery.

Comparison table

Which to choose

PowerPoint remains the choice when decks pass between many people and organisations, when you need add-ins or the full SmartArt and animation set, or when a client sends a template and expects exact output.

DeckCraft fits people who want an offline, open-source presenter that handles ordinary .pptx files, or who generate slides from data and want a scriptable engine. The command-line example in its README creates a slide with a layout and title in one line, which suggests automated report decks as a natural use.

LibreOffice Impress is the mature open-source route now. Google Slides suits real-time collaboration, and OnlyOffice suits teams that want to host editing themselves.
