BackdropKit turns a raw product screenshot or demo video into a complete launch kit without sending it anywhere. Add or generate backgrounds, spotlight and call out UI, redact sensitive text, and export channel-sized images, video, GIF, thumbnail, post copy, and alt text. Everything runs locally in your browser—free, private, and watermark-free.
Hi Product Hunt! We built BackdropKit for the last-mile problem of shipping a product: you have a screenshot or a demo, but making it feel launch-ready usually means uploading it to several tools and recreating every export by hand. BackdropKit keeps that work in your browser. Style a backdrop, focus the exact UI moment, redact private text, generate a local background when your GPU supports it, and export images, video, GIFs, thumbnails, copy, and alt text in one go. It’s free, private, and never adds a watermark. We’d love to hear which launch asset is most painful for you to make today.

The privacy angle is the part I hadn't thought about until reading this, and now I can't unsee it. Every launch screenshot I've looked at closely has something in it the maker didn't mean to ship — a real client name in a sidebar, a bookmark bar, an email in the corner of a demo video.
I'm about to make demo footage for a browser extension, so this is timely. The specific problem I have: the extension only makes sense shown against a real page, but a real page is exactly where the incidental detail lives. Is the approach substitution — swapping in a clean background — or redaction of what's already there? Those fail differently. Redaction leaves shapes that read as "something was here," which is fine for privacy and slightly bad for a launch asset.
