Tabthrough — live demo presenter wót ph

Live software demos break the moment you switch tabs. You lose your place, the room loses the thread, and "let me just find that tab" kills your momentum.

Tabthrough fixes that. It turns the browser side panel into a persistent agenda that travels with you across every tab — so you always know where you are, and so does your audience.

TWO-WAY SYNC BETWEEN AGENDA AND TABS

• Hotkey forward through your steps (Ctrl+→ / Ctrl+←) — the right tab opens or activates automatically
• Switch tabs the normal way (Cmd+Tab, a click, anything) — Tabthrough spots which step you're on and highlights it

NO SCREEN CAPTURE. NO IFRAMES. NO EMBEDS.

Your tabs stay real and fully interactive. Postman is Postman. Grafana is Grafana. Everything works exactly as it does when you're not presenting.

PRIVATE BY DESIGN

The free tier is offline. No account, no sign-up, nothing leaves your browser. Tabthrough reads only the URL of your active tab, and only to match the steps you configured.

WHAT YOU GET (FREE)

• Editorial dark UI built for long demos (JetBrains Mono + Newsreader)
• Markdown slides for intros, transitions, and recaps — right in the panel
• External steps that open a real URL and auto-detect when you land on it
• A presenter window with notes, timer, and next-step preview — drag it to a second monitor so your audience only ever sees the demo
• Three keyboard shortcuts, all customizable in your browser settings:
  Ctrl+→ / Cmd+→ next step
  Ctrl+← / Cmd+← previous step
  Ctrl+Shift+P toggle presenter window

BUILD YOUR DECK RIGHT IN THE PANEL

Click "+ add step" to grow your agenda. Drag to reorder. Click any title, note, or duration to edit in place. Remove a step with its × button. No config file, no JSON to learn — the side panel is the editor.

Start from the built-in deck (Postman, GitHub, Grafana Play) and make it yours.
