plym - Open source CMS for ridiculous speed, auto-SEO & GEO
by•
plym is an open source CMS that serves content to both agents and humans, at ridiculous ⚡️ speed.
Agents get raw markdown: <80% fewer tokens, cleaner context.
Humans get, well, a human page.
It's heavily optimised for speed, SEO and AI discoverability. You hit 100/100 on PageSpeed out of the box for blogs built using plym.
It's highly customisable (everything including the entire template), but ships with pretty well-thought defaults.
Neither a config maze nor an opaque wall.

Hi everyone,
I built plym to solve a problem that bites me every time I (or my clients) launch something new.
There are hundreds of CMSes already, but most fall into one of three buckets:
Feature-rich and customizable, but bloated
Good products, but closed-source and/or full of gated features
The Astros and Hugos of the world: excellent at the core, but you have to assemble everything else yourself, and SEO is on you
plym is my attempt at a fourth bucket:
Open source. Fast by default. SEO and AI agents handled out of the box. And still customizable.
Check out our PageSpeed performance.
A few questions I expect:
1. Is there a cloud version?
Yes. It runs the exact same plymio/plym image, but on managed infrastructure with a 99.99% SLA, priority support, global edge, reliability, etc.
For example, plym Cloud blogs can keep serving even if plym's own servers are down.
2. Why open source?
Keeping plym open forces it to stay good for everyone, including paid users. Wider adoption is a byproduct.
3. Is anyone using it?
Yes. A handful of companies (both paid and free) are already running plym in production. This is just the first official launch.
We dogfood it too:
plym Blog
plym Docs
Both run on plym.
If you're planning to start, also check out the official templates, which are updated frequently.
Planned next: a Claude skill for building your own templates.
I'll be here all day.
What's the one thing your current CMS makes harder than it should be?
