Users see content.
Bots see nothing.

Your content exists. To them, it doesn't.
Open-source rendering infrastructure.
Self-host it. Own it.

Apache 2.0 license. Self-host it, own it, contribute to it.
Years of running rendering at scale taught us what breaks.
We designed around it.
Browsers aren't built for 24/7 service workloads. Memory grows, processes hang, crashes happen at the worst times.
Popular URLs trigger dozens of simultaneous renders for the same page, spiking CPU and taking everything down with it.
If Chrome is unhealthy, bots should still get a response—not 5xx. Uptime isn't optional.
Linux, NGINX, Chromium, React, Vue, PHP, Go are all open source.
The rendering layer shouldn't be the exception.
A renderer loads your pages and runs your JavaScript. That's not something you hand to a black box. You need to see exactly what it does.
If rendering fails, bots see nothing. Your SEO and AI visibility drops to zero. That's not a risk you outsource.
EdgeComet is Apache 2.0-licensed. The self-hosted version is free forever.
A managed cloud option exists for teams that prefer not to run infrastructure themselves.
