Mockly
Create clearly labelled social-media mockups for demos, stories, and prototypes.
Mockly is a free mockup editor for social posts, chat threads and phone screens, built for parody, demos, storytelling and teaching. You fill in names, messages and images, see a live preview inside a device frame, and download a PNG. It is a mockup tool, not a way to fake real conversations, and the editor says so.

Mockly questions
Is Mockly free?
Yes, it is free to use. The home page may ask for an email to open more templates, but there is no account to create.

No. Mockly is for parody, entertainment and educational mockups only. Using it for fraud, misinformation or impersonation is not allowed.
Where are my drafts saved?
Drafts you save stay in your browser's local storage on that device. Clearing your browser data removes them.

Each mockup downloads as a PNG image created in your browser.
Are the images uploaded anywhere?
Avatars and post images you add are used in the browser to build the preview and the PNG. The export happens on your device.
