An interactive agenda that drives your tabs during live demos — so your audience always knows where you are, and you never lose your place.
npm install zod — TypeScript-first schema validation. Zero dependencies. Works in Node, Deno, and browsers.You're mid-demo, the energy's good — then you alt-tab to find the right window. The thread breaks. Your audience checks Slack. You scramble to recover.
Live demos are high-stakes. Every second you spend orienting yourself is a second your prospect is disengaging.
X-Frame-Options. You can't embed them in slides.
Add steps directly in the side panel. Each step is one of two types: a slide step renders full Markdown — headings, bullets, tables, code blocks, and more — right inside the panel; an external step opens a real URL in your main window and auto-detects when you're on that tab.
Press Ctrl+→ to advance. The agenda highlights the next step and your main window switches to the right tab automatically — or opens a new one if needed.
Switched tabs manually? Tabthrough notices the URL, matches it to your deck, and highlights the right step. The agenda always reflects where you actually are — not just where you said you'd be.
Ctrl+→ / Ctrl+← to step through your agenda. Ctrl+Shift+P to open the presenter view. Zero mouse required during the demo.
Agenda drives tabs. Tabs update agenda. URL matching supports wildcards and regex with priority scoring — so the right step highlights even on complex apps.
Open Tabthrough in a separate window on your second monitor. See your notes, upcoming step, and elapsed timer — invisible to your audience.
Steps of type markdown render heading, bullets, and rich text directly in the side panel. No second screen, no separate slide tool.
Each external step declares which URLs belong to it — wildcards (https://*.postman.com/*) or full regex. When you switch tabs manually, Tabthrough scores all patterns by specificity and jumps the agenda to the best match automatically.
Set a target duration per step. The elapsed timer runs from the moment you start. See at a glance if you're running ahead or behind — before you lose the room.
If your demo involves more than one tab and a real audience, Tabthrough is for you.
Run product walkthroughs across Postman, your app, and Grafana without breaking eye contact with the prospect. Every step at a keystroke.
Conference talks, workshops, livestreams. Keep your agenda visible in the side panel while your main window stays clean for the audience.
Step trainees through multi-tool workflows methodically. The agenda keeps everyone oriented — including you, on demo number twelve.
