Researcher open-sources DeckWerk, a slide editor vibe-coded in ~100 hours
Computer graphics researcher Vince Sitzmann open-sourced DeckWerk, a cross-platform slide editor featuring strong video support, real-time collaboration, and Agent support. He says the project was built entirely via vibe coding with about 100 hours of personal time plus substantial agent hours, inspired by DHH's Omarchy Linux and vibe-coding philosophy. It has now fully replaced Keynote as his everyday presentation tool.
Confirmed
- DeckWerk is open source, a multi-platform slide editor
- Core features: excellent video support, real-time collaboration, Agent support (operable by AI agents)
- The author spent 100 personal hours plus extensive agent hours, entirely vibe-coded
- He previously switched from Linux to Mac for lack of a good enough slide editor
- He complained that Keynote has not supported video cropping for over a decade, a key motivation for DeckWerk's video capabilities
- The tool has been used in about 7 talks (per the author)
Why it matters
- Another example that vibe coding can produce production-ready software: a single developer shipped in 100 personal hours what previously required a team
- Reshares from accounts like CSProfKGD show the case resonated widely in academic and technical communities, especially around the long-standing gap in Linux productivity tools
- For the slide-tool market, open source plus real-time collaboration plus native video support differentiates it against Keynote/PowerPoint
