Cartoon Studio (open-source desktop app)

Technical Positioning
An open-source desktop app for making simple 2D cartoon scenes and shows, going from script to video without a big animation pipeline. Local-first, bring-your-own API keys for AI features.
SaaS Insight & Market Implications
This open-source desktop application addresses a clear pain point in content creation: simplifying 2D animation for non-experts. By automating lip-sync, word timestamps, and mouth cues, it significantly reduces the technical barrier to entry for producing animated content. The "script to video" pipeline, leveraging existing SDKs like Jellypod's Speech SDK and HeyGen's HyperFrames, demonstrates effective integration of specialized tools. Its local-first, bring-your-own-key model for AI features aligns with privacy and cost-control demands. This product targets a growing creator economy segment seeking accessible, efficient tools for visual storytelling, bypassing complex animation pipelines.

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. :DA 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 sourceIt 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:x.com/deepwhitman/statu... the repo:github.com/Jellypod-Inc/cart... to answer questions and appreciate any feedback!

The LLM/deterministic split is the smart call here. You can iterate on a script without the rest of the pipeline drifting under you. Curious how far the vowel-per-word heuristic holds before you wish you had Rhubarb, but "regenerates instantly" sounds like the right tradeoff for a studio loop.

Very cool! I will definitely try this out - cartoons is something I have been interested in for a while. Will check it out.

This looks great. Curious about the lip-sync — viseme set or just open/closed mouths? The South Park style is super forgiving but HyperFrames quality seems like it'd need more.

static video with text2speech audio and two circles moving representing the mouths: "OMG I might have a show on my hands "

I went into this imagining something like Synfig Studio (https://www.synfig.org/) or Moho (https://moho.lostmarble.com/). "Studio" here is quite far from what it actually is: lip-syncing in static characters.Also, Moho offers far more comprehensive (and comprehensible!) lip-sync: https://lostmarble.com/papagayo/I get that you're using AI to boost capability with less effort, but at the moment, I think the more specialized tools are still a better avenue for this.Lastly, I followed the link to Jellypod (https://www.jellypod.com/). It's pretty good, but falls into a vocal "uncanny valley". Even a human reading from a script wouldn't sound that perfect; the enunciations immediately come across as artificial.Now, if this was an extension to Synfig (also open source!), it would be a much more interesting venture...
