Doory is a free, open-source design editor that runs in your browser. You can build social posts, posters, slides, invitations, resumes, thumbnails and business cards, starting from one of its templates or a blank canvas. Everything on the page is editable, from text and shapes to photos, and it also covers animation and music if you want to turn a design into a short video or GIF. Doory is completely free with no paid tier, locked features or ads, and developers can self-host it with Docker.
