Keep your Sims 4 Mods healthy, organized & crash-free .
The offline-first health manager for The Sims 4. Inventories your Mods folder, detects conflicts & duplicates, verifies compatibility, and keeps raw files strictly on your PC.
Script mods are strictly parsed for class signatures and injection hooks using Abstract Syntax Tree tokens. 0 bytes of Python or machine code executed on your machine.
Local files stay strictly on your NVMe/SSD drive. Only the 64-character SHA-256 checksum is compared against the verified creator registry to test for out-of-date patch versions.
Before modifying or moving any duplicate package, a timestamped snapshot is saved into .simsmodhealth/backups.
How Sims Mod Health diagnoses 50GB folders in under four seconds.
Built in Rust with native thread pooling. No slow browser engines touching your files, no game launch delays.
Local Scan & AST Parsing
Instant multi-threaded directory crawl. Raw .package and .ts4script inspected on-device with zero code execution.
Metadata-Only Resolution
Only cryptographic hashes & creator manifests resolve against the cloud database. Your files never leave your drive or get uploaded anywhere.
Intelligent Diagnostics
Pinpoint version mismatch, broken XML tuning tables, duplicate package files, and missing base libraries before the game even launches.
Safe Reversible Actions
One-click disable, safe folder sorting, backup creation, and atomic rollback. Never worry about corrupting your save files again.
Raw .package and .ts4script files never upload. Period.
Unlike web scanners that demand you drag gigabytes of CC files into an unknown remote cloud, Sims Mod Health treats your storage as an isolated vault. We only compare compact 32-byte cryptographic hashes over encrypted HTTPS.

Six Guiding Principles Behind Every Diagnostic
Built by creators and long-time players who care deeply about creator attribution, user privacy, and mod health.
Offline-First Design
Scanning and local mod inventory work completely without an internet connection or user account. Play offline, diagnose offline, fix offline.
Evidence Before Confidence
Unknown mods are never silently flagged as "Broken" or deleted. We only show alerts when explicit binary or XML collisions are verified.
Safe Static Inspection
Python script mods (.ts4script) are parsed purely for module signatures and tuning tables. Code is never evaluated or executed.
Explain, Do Not Alarm
Resource overlaps are framed as "potential interactions" with helpful context, rather than scary red error popups that induce panic.
Recoverable Changes
Every disable, subfolder move, or batch quarantine creates an automated snapshot. Revert any action at any time with a single click.
Source-Respectful
We honor modder release channels, Patreon tiers, and explicit developer preferences. Zero file re-hosting, zero paywall bypassing, zero unauthorized scraping.
