I'm Daniel — solo founder. I build APIs + apps for developers and AI agents.
Two products live: @rendexdev (rendering API) + @beaconsafeapp (personal-safety app).

We treat “rendering” too narrowly. You don’t always want a screenshot of a finished page. Sometimes you want a hosted render URL to drop into og:image, or clean Markdown from any URL to feed an LLM.
Same Rendex API: hosted render links + URL extraction.

Screenshot APIs do one thing.
Rendex does screenshots, HTML-to-image, URL-to-PDF, and geo-targeted captures from 195 countries — one API, one SDK.
The "screenshot API" category is too small. Rendering is the category.

Screenshot APIs give you a screenshot.
Rendex gives you one from 195 countries.
