Keyframer Preview vs Grenade

The fastest way to feel your React Native animations. Keyframer is the companion app for Keyframer.dev, the visual animation editor for React Native. Design your animation in the web editor, scan the QR code, and watch it run natively on your phone, powered by the same Reanimated engine your production app uses. Animations that look right in a browser can feel wrong on a device. Timing, easing, gestures, and scroll physics only tell the truth on real hardware. Keyframer closes that gap in seconds, with no build step and no cable. LIVE PREVIEW Scan the QR code in the editor and your canvas appears on your phone instantly. Keep editing on your desktop, every change streams to the device in real time, so you can tune springs and keyframes while feeling the result in your hand. TRULY NATIVE PLAYBACK This is not a video or a web view. Your scenes run as real native animations, the same interpolations, springs, and gesture handlers that Keyframer's generated Reanimated code ships to production. INTERACTIONS INCLUDED Pan, tap, and pinch gestures, scroll-driven transitions, and node-graph logic all work in the preview. If your animation responds to touch, you can test it the way your users will experience it. YOUR SCENE LIBRARY Sign in to browse every canvas you've saved in the editor and preview any of them on demand, on the couch, in a meeting, or on the bus. OPEN SHARED CANVASES Received a keyframer.dev share link? Scan the QR on the share card to open a live, interactive version of the animation on your device. MADE FOR React Native developers, design engineers, and motion designers who prototype with Keyframer.dev and want to validate motion on real devices before shipping. Start designing at keyframer.dev, your first canvas is a QR scan away from running in your pocket.

Grenade is a remote for the AI coding agents running on your Mac or Linux computer. Claude Code, Codex or a plain shell run in terminals on that computer; your iPhone shows every one of them with a live status, and lets you read, answer and type from wherever you are. • See at a glance which agent needs an answer, which has finished and which is still working. • Approve a command, answer a question or accept a plan with one tap. The card shows the full command first. • Read the terminal live, or the plain activity view of what the agent said. • Type, paste an image, or hold the mic and talk. • Talk: ask out loud what needs you and hear the answer. Grenade knows your sessions and passes on what you say. It runs on OpenAI or Google Gemini with your own API key, kept on your computer. • Start new sessions in any folder, and group them like tabs. Private by design. On your Wi-Fi the phone talks straight to your computer; anywhere else it goes through a relay that forwards only end-to-end encrypted bytes. No account, no tracking, nothing collected. Needs the free Grenade software on your Mac or Linux computer: brew install holdgrenade/tap/grenade, then grenade setup (Linux: holdgrenade.com/install).
