Cybersec Research · App Dev · AI Lab · 🇵🇭
An information-security & technical journal — plus the tools we build. We share what we learn as penetration testers, programmers, and network administrators so others can understand cyber risk and defend against it.
Built by us
Software we design and ship — and where new releases get announced.
Your day, on the record
Offline-first daily logs, notes, tasks, photos and voice memos for any project. Installs like an app, works with no signal, and syncs privately to your own Google Drive.
Plan, lead & play — in one place
The all-in-one app for worship teams: song charts with chords, one-tap transpose to any key, and a dashboard for members, trainings and schedule. AI practice tools on the way.
IRC for people who run channels
A modern, native, cross-platform IRC client with a battle-tested operator & channel-protection toolkit baked in — a ground-up rebuild of the classic RAVE IRC script suite (©2002, acronix on DALnet).
// AI Lab
Agents, automation and AI-assisted security & developer tooling — documented as it ships.
From the journal
Hands-on guides on penetration testing, hacking tools, networking, and the systems we live in.

In Part 1 we covered PHP's basic syntax. As promised, this time we'll look at variables and constants — the two ways PHP stores information for you to use later.

The site you're reading has no web server, no database, and nothing to patch. Here's how 'static + edge' hosting works — and why it's faster and safer than the old way.

SQL injection broke databases. Command injection broke shells. Prompt injection breaks AI — and as we wire LLMs into agents and tools, it's the #1 risk to understand.

Who we are
Coders Republic is a cybersecurity research team that researches, educates, and builds.
We're a team based in the Philippines with backgrounds spanning offensive security, software engineering, and systems administration — led by Acronix, a Certified Ethical Hacker working in the field since 2000.
Three things drive our work. Security research: we share the techniques, tools, and discoveries we encounter as penetration testers so others can understand real-world cyber risk and defend against it. App development: we design and ship our own software — see the apps above. And AI: we're moving into an AI-driven workflow and documenting what actually works in the AI Lab.
We don't just write about security — we practise it. We harden our own systems, run frequent audits, and treat everything we build as something to defend. It's our way of giving back to the community and helping make the Internet a safer place.
