KoalaSnap
A free chat mockup generator and social post simulator for WhatsApp, Discord, Telegram, and more. 100% privacy-friendly and client-side.
Overview
KoalaSnap is a free, open-source online utility designed to generate realistic mockup screenshots of various chat and social media platforms including WhatsApp, Discord, Telegram, Signal, iMessage, and X (Twitter). Modify contact names, statuses, bubbles, emojis, and avatars. All rendering is performed completely client-side in your local browser. No data is stored, tracked, or sent to any server.
Backstory
This project was built as a proof of concept. After seeing someone on Reddit charge money for a chat mockup generator, I wanted to prove that a similar tool could be built in just one or two hours using a free AI model (DeepSeek).
