Render chats, AI chats, posts, comments, stories, and emails via HTTP — across 40+ apps. Image and video. One subscription. $99/month.
"Mockly manages to set itself apart while iterating on such a popular idea by simply being usable."
You're in good company
30,000+
Creators, marketers, and production teams use Mockly for realistic mockups that do not depend on live app screenshots.
One editor. 40+ apps. Still image or video when the story needs motion.

One HTTP API for generating mockups. Six types, image and video, every app the editor supports.

Image renders
PNG export, sub-second response, returns a signed download URL.

Frequently asked
Quick answers.
Which mockups does the API support?
Six mockup types: chats (WhatsApp, iMessage, Instagram, Discord, Telegram, and 18 more), AI chats (ChatGPT, Claude, Gemini, Grok, Perplexity), social posts (X, Instagram, LinkedIn, Threads, Bluesky, and more), comment threads (YouTube, TikTok, Reddit, and more), stories (Instagram, Snapchat), and emails (Gmail, Apple Mail, Outlook). 40+ apps in total. Anything settable in the editor is settable via the API.
Does it support both image and video?
Yes. POST returns 200 immediately with the download URL for images, or 202 with a status URL for videos. Video is available for chats, stories, and AI chats — AI chats animate with a typewriter stream. Posts, comments, and emails are image-only. Typically sub-second for images, 30s–2min for videos depending on length.
How is authentication handled?
Bearer authentication via the standard Authorization header. Mint keys in your account; pass them as `Authorization: Bearer mk_live_…`. Keys are shown once at creation and stored as a hash.
Are there rate limits or quotas?
Each subscription includes 10,000 image renders and 500 video renders per month — generous defaults that most customers won't approach. Need more? Email us and we'll work it out.
What does it cost?
$99/month, monthly billing, cancel anytime. One subscription gives you image and video renders across all 6 mockup types and 40+ apps. No tiered pricing, no per-render fees.
Where are the docs?
The full API documentation is at /api/docs — quick start cURL example, endpoint reference, the request body shape for every mockup type, and error codes.
