Using the web for presentations was once a niche choice among technical practitioners. But over the past two years, more and more non-technical users have been trying it — in academic presentations, product launches, corporate training, and similar scenarios, web-based slides are moving from the fringe to the mainstream. The driving force behind this isn’t complicated: web technologies are naturally cross-platform, version-control friendly, and offer interactivity that traditional PPT cannot easily achieve.

This article reviews several web presentation tools worth attention, split into two layers — core frameworks and AI generation — with directly accessible project links.

1. The Core Framework Layer

The infrastructure of web presentations is built on a set of open-source frameworks. They liberate slides from proprietary formats and rebuild them on open web technologies.

reveal.js: The “De Facto Standard” for HTML Presentations

reveal.js is currently the most mature HTML presentation framework, developed by Hakim El Hattab. Its core positioning: anything that can be done on a web page can be used in a presentation.

The framework supports vertically nested slides, speaker view (with timer and next-slide preview), Auto-Animate, LaTeX formula rendering, and more. Slide transitions include fade, slide, convex, concave, zoom, and other modes. For those unfamiliar with code, the same author also provides a companion no-code editor, slides.com.

reveal.js suits technical presentations with high requirements for interactive effects — for example, embedding live code execution, iframe web content, or complex CSS animations.

Slidev: The Developer’s Markdown Choice

Slidev is designed specifically for developers. Its tech stack is built on Vite + Vue 3 + UnoCSS, using Markdown as the content source format. Its biggest advantage is unifying the “writing code” and “making slides” workflows in the same environment.

Slidev’s standout features include Shiki-powered code highlighting, built-in live code demos, Mermaid diagram support, KaTeX math formulas, presenter pen annotations, and a built-in recording tool. For deployment, running slidev build outputs a static site that can be hosted on any platform.

For developers who already manage documents with Git, Slidev’s Markdown source files are naturally version-controlled — an advantage traditional PPT can’t match.

Marp: The Lightest Markdown Option

Marp stands for Markdown Presentation Ecosystem and offers an out-of-the-box experience as a VS Code extension. After installing the extension, create a new Markdown file, add the marp: true front-matter config, and you’re ready to make slides.

Marp has the lowest learning curve of the three, and supports exporting to PDF, PPTX, and HTML. It suits quick academic reports, work briefings, and other scenarios that don’t demand high design complexity.

Spectacle: A Presentation Option for the React Ecosystem

Spectacle is a React component-based presentation framework maintained by Nearform (formerly FormidableLabs), with slides written in JSX. It integrates seamlessly with the React ecosystem and supports live coding. For teams already deeply invested in the React stack, Spectacle enables component reuse — for example, embedding elements from your UI component library directly into a deck.

2. The AI Generation Layer

Frameworks solve the “how to present” problem; AI tools are starting to solve “how to generate content.” Here are the open-source options worth watching.

Presenton: The Most Feature-Complete AI Presentation Generator

Presenton has 4.8k stars on GitHub and is open sourced under the Apache 2.0 license. It positions itself as an open-source alternative to Gamma, Beautiful.ai, and Decktopus.

The project’s core features include:

• BYOK model support: Use APIs from OpenAI, Gemini, or Anthropic, or connect local models via Ollama
• Template inheritance: Upload existing PPTX files to use as design templates
• Fully local operation: Offers both an Electron desktop app and Docker self-hosting; all processing can be done locally
• Built-in MCP Server: Supports the Model Context Protocol for integration with other AI toolchains

Deployment is very simple — a single Docker command starts the service. For data-privacy-sensitive scenarios, such as internal corporate reporting or presentations involving trade secrets, Presenton’s local operation capability is an important plus.

PPTAgent: An Academic-Grade Generation Option

PPTAgent is a research project published at EMNLP 2025, developed by the Institute of Computing Technology, Chinese Academy of Sciences (ICIP-CAS). Its distinguishing feature is a systematic quality evaluation mechanism. The project uses a two-step generation pipeline and includes the PPTEval scoring system, which quantitatively evaluates generated results across three dimensions: design, flow, and content quality.

PPTAgent also supports Docker deployment in seconds. It suits research or enterprise environments that need quantifiable evaluation of generation quality — for example, when you need to prove to clients that AI-generated content meets a specific quality bar.

3. The Toolchain Layer: Format Conversion

Dedicated conversion tools bridge web presentations and traditional workflows.

DeckTape: High-Quality PDF Export for HTML Presentations

DeckTape is built on Puppeteer and the Chrome rendering engine, and can export 13+ HTML presentation frameworks — including reveal.js, Slidev, impress.js, and remark — to high-quality PDF. Its usage is simple:

The tool also supports selective export (e.g., only pages 1, 3, and 5-10), multi-resolution screenshot capture, and Docker containerized operation. For offline distribution or print backup scenarios, DeckTape is an indispensable part of the web presentation workflow.

4. Selection Advice

5. A Workflow Worth Watching

These tools are currently forming a clear pipeline:

Markdown/text → AI-generated content → web presentation framework rendering → DeckTape PDF export

This means users can generate an outline with AI, refine it in Markdown with Slidev or Marp, build it into an interactive web presentation, and export a PDF with DeckTape as a fallback. This “web-first, PDF as backup” pattern is the technical foundation behind the claim that “web presentations are better.”

Web presentations have objective advantages in interactivity, version control, and cross-platform consistency. But they’re not a silver bullet: traditional PPT still holds ground in business compatibility, review/annotation features, and acceptance among non-technical users — real constraints web solutions must face. Which tool you choose ultimately depends on your specific use case and audience.
