New in Rendex: Mustache data templating.

Feed one HTML or Markdown template + a data object
→ get PNG/PDF invoices, reports, and cards back.

One template, many documents — no per-variant render code.

After Kitestring shut down, I built the check-in app I wished existed.

Beacon Safe: set a daily check-in. Go silent and your people get an email, text, and an automated call — even if your phone's dead. No location tracking.

Point it at any URL → we render it in real Chrome on a schedule and show you exactly what changed: before, after, and the diff ringed in orange.

Email + webhook alerts. Same API key as your screenshots.

@galluzzo_julian We understand having to keep up with Ai for sure! Keep it up!

@danelliotdev @codewithimanshu Agree with your agree!

[Rendex — Rendering API @rendexdev]

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.

@codewithimanshu Oh great, more clickbait! Yay.....

[Rendex — Rendering API @rendexdev]

Your dashboard or report, as a PNG your backend can drop straight into an email, a Slack message, or a PDF. Send HTML, get an image back. No headless Chrome to babysit.

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.

[Rendex — Rendering API @rendexdev]

Screenshot APIs give you a screenshot.

Rendex gives you one from 195 countries.
Same API call, add country_code: "JP".

Your site looks different from Tokyo.
