Show your open source project in action
Record GIF demos for READMEs, contribution guides with keyboard overlays, and architecture walkthroughs. Free, local, and built for developers.
What's getting in the way
- README demos are static screenshots that don't show workflows
- New contributors struggle without visual setup and contribution guides
- Recording tools cost money — open source has no budget
- GIF tools produce low-quality, oversized files
