Drop folder to scan

Welcome to SMP Client

Keep your Minecraft mod folder in sync

SMP Client checks the mods already installed in a local Prism or Minecraft instance against the latest published SMP pack. Your files stay on your device, and nothing changes until you review and confirm the proposed actions.

Local-first

How it works

From folder to reviewed update

1
Select your instance
Choose or drop mods, .minecraft, or a Prism instance folder. The app finds the actual mods directory.
2
Scan locally
The browser calculates JAR hashes locally and compares them with the selected Standard or Barebones pack catalog.
3
Review every action
Missing, changed, disabled, and unrecognized mods become an explicit checklist. Actions start unchecked.
4
Apply your way
Chromium can apply confirmed changes after write permission. Other browsers receive an exact guide or generated local script.

Safety model

Designed to be reversible

Files are inspected in your browser, not uploaded.
Nothing is selected or applied automatically.
Unexpected JARs are disabled instead of immediately deleted.
Replaced files are backed up before direct updates finish.
Permanent disabled-mod cleanup is a separate confirmation.

Browser support

Chrome-family browsers support reviewed direct updates. Firefox and other browsers still provide the full scan, checklist, guide, and script workflow.

You can also drag a supported folder anywhere onto this page.
