What our research says

Gamma

The tool that genuinely displaced PowerPoint for a lot of people, and it is profitable enough not to need your money — but credits, not seats, decide how much a plan is actually worth.

Pros

  • Layout and image choice happen without picking a template first
  • One document publishes as a deck, a doc or a live web page
  • Plus at $8/user/month already removes the Gamma badge
  • Profitable at over $100M ARR, so the vendor is not a runway risk

Cons

  • Credit accounting is opaque — a premium image can cost up to 125 credits
  • API keys are locked to Pro and above
  • The free plan's 400 signup credits do not go far on image-rich decks
  • Export fidelity to PowerPoint degrades on complex layouts

htmlslides

htmlslides trades the usual slide-deck file format for plain HTML, which means decks run and animate in any browser and share as a link rather than an attachment. It's a solo-developer product, so the template and feature library is smaller than an established incumbent.

Pros

  • Presentations run as real HTML, playable and animated in any browser without special software
  • Shares as a single link rather than requiring a file download
  • Supports importing an existing deck from a GitHub link or local file
  • Speaker Mode gives a dual-screen presenter view with notes, not just a bare slideshow

Cons

  • Template library is limited, especially on the free plan (10 templates)
  • Built and maintained by one developer, a continuity risk versus larger platforms
  • Current Pro price is an introductory launch offer and may rise later

Which one fits

Choose Gamma if you need

  • Anyone who needs a presentable deck out of rough notes in minutes
  • Teams publishing one-page sites and documents without a website tool
  • Users who want AI layout but expect to keep editing afterwards

Choose htmlslides if you need

  • Presenters who want a shareable link instead of exporting and emailing a file
  • Developers comfortable importing/editing decks as HTML/GitHub content
  • Anyone wanting built-in interactivity (charts, flip cards) inside a slide, not just static text
