Open toolsfor real work.

Tachipy is Mateo's independent software workshop. Small, focused tools that solve one concrete problem — without forced accounts, data harvesting, or unnecessary bloat.

01 / THE TOOLS

Two problems.
Two clear answers.

Every Tachipy project starts with one tightly defined task. Everything else stays out.

CMS SECURITY FORENSICS

Shellhound

Shellhound is a local forensic workbench for compromised CMS systems. It indexes the webroot, access logs, and a database export, reconstructs attacks, and connects findings, timelines, and IOCs back to the underlying evidence.

  • CMS incident response
  • Webroot + logs + DB
  • Evidence-first

02 / BUILD PRINCIPLES

Less platform.
More tool.

Tachipy does not follow a growth plan. The projects should stay useful, understandable, and independent.

  1. 01
    One problem per product.

    A clear purpose instead of an endless feature list.

  2. 02
    Private by design.

    Sensitive data stays local whenever the browser can do the work.

  3. 03
    Built in the open.

    Source code, decisions, and limitations are allowed to be visible.

03 / IN THE LAB

What is being
built now.

Behind the finished tools, the workshop keeps moving: small experiments, measurements, and notes straight from the repositories.

ACTIVE / EXP_003

Shellforge

Generate synthetic CMS incidents and make Shellhound's detection performance measurable.

NEXT / OPEN SLOT

Next experiment

Small enough for one evening. Useful enough to become more.

STATUS / LOOKING FOR AN IDEA
LATEST NOTE / AUG 9, 2026

Blattwerk stays a pure browser tool.

Files and signatures never leave the session.

HANDLE / TACHIPY

Built by Mateo.
Developed in the open.

I publish independent open-source projects under Tachipy — built from curiosity and released when they can be useful to others.
