Slidev if you want the published Pitch / Gamma path (Markdown for developers). reveal.js if you want that HTML framework — /compare/slidev-vs-reveal-js.

A .pptx stays on /replace/powerpoint (ONLYOFFICE). This page is a developer deck you build.

Prezi Cloud stays skipped. impress.js is an MIT CSS3 canvas, not a hosted Prezi clone.

Slidev, reveal.js, and Marp are MIT. You pay hosting. Template users never pay c17.

Stacks / Docs

Easy

Slidev / reveal.js

A deck you build. Slidev is MIT; reveal.js is MIT — Pitch or Gamma without the hosted slide seat.

The problem

Pitch and Gamma are hosted presentation desks. You wanted slides as files you keep. Slidev is MIT (slidevjs/slidev; last push 23 Oct 2026) — Markdown decks for developers. reveal.js is MIT (hakimel/reveal.js; last push 30 Sep 2026) — the HTML presentation framework. Marp is MIT (marp-team/marp) if the job is Markdown-to-PDF. impress.js is MIT if you want that CSS3 canvas (not Prezi Cloud). This is not Pitch's every workspace SKU or Gamma's every AI-generate SKU. A PowerPoint file stays on /replace/powerpoint (ONLYOFFICE). A formal diagram stays on /replace/lucidchart (diagrams.net). Prezi Cloud stays skipped: no product-level self-hosted Prezi path.
