Thanks, HAOYU! I appreciate the support. If you get a chance, feel free to check out the live demo and let me know your thoughts. Always happy to hear feedback from fellow developers. 🚀

this looks interesting! I'm curious though, is there a headless mode? like can I use it as a backend and bring my own React frontend?

also the github link says code drops March 17, so I can't really poke around yet. any chance you have a demo with the admin panel visible? the marketing site loads fast but I want to see what the content editing experience actually feels like day to day.

honestly the CodeIgniter choice is kind of nostalgic lol. haven't touched CI since college.

Great questions, Priya — thanks for the thoughtful feedback!

Regarding headless usage, SHONiR CMS is currently designed as a traditional CMS, but its architecture (built on CodeIgniter 4) makes it quite flexible. It’s definitely possible to expose content through APIs and use it with a React or other frontend frameworks, and a more formal headless-style integration is something we’re considering as the project evolves.

You’re right about the GitHub repository — the full source will be published on March 17, 2026, but in the meantime you can explore the live admin panel demo here:

Admin Panel: https://8.shonir.com/shonir-cms/Users

Password: 923333336426

That should give you a feel for the content editing workflow and day-to-day admin experience.

And yes — CodeIgniter definitely has a nostalgic reputation, but CodeIgniter 4 is a very different beast compared to the older versions many of us used years ago. It’s modern, lightweight, and surprisingly powerful for building scalable systems.

If you get a chance to try the demo, I’d love to hear your thoughts or suggestions! 🚀

honest question - what does this actually do better than something like Strapi or Directus?

CodeIgniter 4 is fine but the PHP CMS space is already crowded. "fast and lightweight" is what every CMS says. the real questions are:

what's the plugin/module ecosystem look like? because building everything from scratch gets old fast on client projects.
how does content modeling work? is it code-based or does it have a UI for defining content types?
any headless/API mode or is it tightly coupled to the frontend?

also "full open-source code available on March 17" means i can't actually look at the codebase yet. that makes it hard to evaluate. the demo site loads quick though, i'll give you that.

not trying to be negative, genuinely curious where this fits. if you're targeting agencies building client sites, the comparison isn't WordPress. it's the modern headless CMS tools that already have API-first workflows and content previews figured out.

what's your actual differentiator beyond being lightweight?

SHONiR CMS isn’t trying to be another WordPress clone, nor a Strapi/Directus replacement. Its differentiator is performance‑first architecture in PHP: multi‑CDN integration, environment‑driven caching, and enterprise‑grade helpers baked into the core.

Ecosystem: Instead of a plugin bazaar, it ships with curated utilities (SEO, caching, formatting, navigation) so agencies don’t rebuild basics every project.

Content modeling: Code‑first with database schema, but exposed in the admin panel for editors—lighter than Strapi’s UI, faster to deploy.

Headless/API: Hybrid mode. You can serve JSON endpoints for React/Vue frontends, or use the built‑in theme system.

Open source: Repo goes live March 17, so evaluation beyond the demo is limited until then.

In short: Strapi/Directus = UI‑heavy, API‑first ecosystems. SHONiR CMS = PHP‑based, hybrid, speed‑optimized, with built‑in helpers. It’s aimed at agencies that want fast, scalable sites without adopting a Node.js stack
