open-slide turns React components into presentation slides, with a development preview where you can edit elements or leave comments for a coding agent.

The framework handles the slide canvas, navigation and presentation runtime. Your agent writes the deck source; you review the result and choose how to present or export it. Use this as a first read, not a recommendation. Open the original project before trusting details like terms, limits, privacy, cost, setup, or safety.

What it is

A deck made of source files

Each page is a React component on a fixed 1920 by 1080 canvas. Deck files and their assets live in a workspace you can revise through code.

Why it stands out

Visual changes reach the source

The development inspector supports direct element edits and comments attached to the relevant code. Agent skills connect those comments to a later editing pass.

Availability

CLI scaffold and local runtime

The CLI creates a workspace; the core package runs its preview and build. Official docs and a demo show the workflow. HTML, PDF and PowerPoint exports serve different handoffs.

Why it matters

What makes it useful

For a product update or technical talk, you can ask a coding agent to draft the deck and then review the actual slides. Small text and layout adjustments can be made in the inspector; changes that need explanation can be left as comments for the agent. The deck remains React source.

Notable points

What stands out

Inspector comments are stored as @slide-comment markers next to the selected element in source. The /apply-comments documentation describes an agent pass that reads those markers, edits the surrounding code and removes resolved markers. It says comments the agent cannot resolve are left in place and reported as skipped, so a review note is not the same as a completed change.

Before using

What to review

For the current v2 toolchain, the migration guide specifies Node 20.19+ or 22.12+. It also warns that an old workspace's separate Vite dependency can conflict with the core package, and describes removing that entry and reinstalling.

Choose the handoff format by installed version. The v2 changelog lists editable PPTX text boxes, shapes and images; the export guide still describes image-based PPTX and says native editable export is unavailable. Those official pages disagree. Inspect the version and output before promising an editable deck.

Check what goes into a public build. The export guide says it includes decks under slides/, their imported assets and the runtime. Hiding the deck browser or toolbar changes the displayed interface; review the actual files you intend to publish.

For a proxied development server, the config docs explain allowing the workspace domain. They warn that accepting every host with allowedHosts: true disables Vite's DNS-rebinding protection and reserve that setting for a trusted network.

The repository declares MIT. Review the original project and separate terms for your coding-agent provider, fonts, images and other imported assets.

Reader fit

Who may find it relevant

Developers or technical presenters who want to revise a deck as React source and are comfortable reviewing an agent's changes.

Teams that want visual feedback to point at specific slide elements instead of explaining every change in a separate chat.

Readers needing only a finished presentation-app file should compare the actual export with that need. Source authoring and exported editability are separate choices.

Editorial note

Why LifeHubber lists it

When rehearsing a talk, the presenter-mode documentation shows speaker notes stored in an array alongside the page array, with matching positions. A page without notes uses undefined in that position, so later notes stay aligned with their slides. Presenter view opens in a second window with the current slide, next slide, notes and timer. This connects the deck source to the speaking script without putting that script on the audience-facing slide.
