Show HN: Cartoon Studio – an open-source desktop app for making 2D cartoon shows Hi HN — I built Cartoon Studio, an open-source desktop app for making simple 2D cartoon scenes and shows. The basic flow is: place SVG characters on a scene, write dialogue, pick voices, and render to MP4. It handles word timestamps, mouth cues, and lip-sync automatically. This started as me playing around with Jellypod's Speech SDK and HeyGen's HyperFrames. I wanted a small tool that could go from script to video without a big animation pipeline and next thing I knew I was trying to create my own South Park style show and here we are. :D A few details: - desktop app built with Electron - supports multiple TTS providers through Jellypod's Speech SDK - renders via HyperFrames - lets you upload or generate characters and backdrop scenes - includes default characters/scenes so you can try it quickly - open source It runs from source today. AI features use bring-your-own API keys, but the app itself is fully inspectable and local-first in the sense that there’s no hosted backend or telemetry. Here are some fun examples of the the types of videos you can create: https://ift.tt/sOU8Map https://ift.tt/tpIfRSA And the repo: https://ift.tt/tHF81J9 Happy to answer questions and appreciate any feedback! https://ift.tt/tHF81J9 April 22, 2026 at 11:56PM
