Welcome to the Minecraft Mod Updater & Builder!
This tool is your one-stop shop for managing your Minecraft mods. You can
easily find updates for your entire mod list, discover new mods, and
export a ready-to-use modpack for your favorite launcher.
Ready to Start?
To get started, you can upload an entire modpack (.mrpack), individual mods or plugins
(.jar), resource packs, shaders, or data packs (.zip), import a previously
exported modlist (.json), or use the search bar to find new content. Then, click the
"Update" button to see the magic happen!

Minecraft Mod Updater & Builder
This tool helps you update your existing Minecraft mods or build a brand new mod list from scratch. It uses
the Modrinth API to find the latest compatible versions and can export your list as a standard Modrinth
modpack. Note: This tool only searches Modrinth - mods from CurseForge or other sources won't be found.
Dependencies are automatically detected and added to ensure your modpack works properly.
How to Use:
Loader / Version: Select your desired mod loader (Fabric, Forge, NeoForge, Quilt) and target
Minecraft version.
Upload Files: Drop a .mrpack file to load a modpack, or drag and drop your local
.jar (mods, plugins) and .zip (resource packs, shaders, data packs) files into
the upload area. You can also drop a previously exported .json modlist to restore it.
Search for New Mods: Use the search bar to find and add mods directly from Modrinth.
Process Your List: Click "Update" to find the latest compatible versions and dependencies.
Understanding Results:
Color-Coded Borders:
Green border: Successfully found updates for these mods
Blue border: Dependencies automatically added to ensure compatibility
White border: Mods already up-to-date with the latest version
Yellow border: No compatible version found for your selected loader/version
Red border: Mod not found on Modrinth or file could not be processed
Icons Next to Mod Titles:
Box: Standard mod
Paintbrush: Resource pack
Glasses: Shader pack
Brackets: Data pack
Open Box: Modpack
Plug: Plugin
Puzzle Piece: This mod is required by another mod in your list
Chain Link: This mod has dependencies that were automatically added
Lightning Bolt: Data loaded from cache for faster performance
Double Checkmark: This mod is already up-to-date with the version selected
Supported Environments: Each result shows where that mod runs. On updates, the label follows the version selected in the dropdown.
Client-side: Runs on the client only
Client (server optional): Needs the client; installing on the server can unlock extra features
Singleplayer: Intended for singleplayer only
Server-side: Runs on the server only
Server (client optional): Needs the server; installing on the client can unlock extra features
Dedicated server: Dedicated server only
Client & Server: Must be installed on both client and server
Client or Server: Works fine on either side alone
Either (prefers both): Works on either side, but works best with both installed
Features & Tools:
Search: Use the search boxes to quickly find specific mods in your results
Sort: Organize results by name, downloads, followers, last updated, or file size
Filter: Narrow results by category, channel, environment, source, dependencies, and more. The Environments list only shows labels present in your current results.
Copy Lists: Use the copy button to quickly copy mod names to your clipboard
Export Lists: Use the export button to download the current list as CSV, JSON, Markdown, or plain text.
The JSON format is the one you can re-import — CSV/Markdown/plain text are share-oriented and not importable.
Import Modlist: Drag and drop a previously exported .json file onto the upload area to
restore that modlist. Loader and Minecraft version are set to match the export (same as dropping a
.mrpack).
Version Selection: Choose between Release, Beta, or Alpha versions for each mod
Download Options: Download individual mods or get everything as a ready-to-use .mrpack
file

Privacy Policy
Minecraft Mod Updater is a static, client-side web application. There is no application backend
collecting or storing data about you. Lookups and file processing happen locally inside your browser tab.
Your Files
Any .jar, .zip, .mrpack, or .json files you upload
are processed entirely in your browser. The file contents are never uploaded to mcmodupdate.app.
To identify mods, the app computes a SHA-1 hash locally and sends that hash to the Modrinth API
(api.modrinth.com). When you close or refresh the tab, the files are gone from memory.
Browser Storage
To improve performance, the application stores a small amount of non-personal data locally on your device:
localStorage — caches the list of Minecraft versions and Modrinth platform statistics so the
app loads faster on subsequent visits.
sessionStorage — caches mod lookups (and related project titles) during your current tab
session and is cleared automatically when you close the tab.
You can clear this data at any time using your browser's site-data controls. The site does not use
tracking cookies.
Third-Party Services
The site loads resources from the following third parties. Each may receive standard request data
(your IP address, user-agent, and the resource being requested) under their own privacy policies:
Netlify — hosts this site. Like most hosts, it may keep standard web-server request logs.
Modrinth API (api.modrinth.com) — used to search for projects, look up file hashes,
and retrieve version and dependency information.
Modrinth CDN (cdn.modrinth.com, cdn-raw.modrinth.com) — serves mod
icons, gallery images, and the mod files you choose to download.
jsDelivr — public JavaScript content delivery network used to load the
libraries the app depends on (JSZip, marked).
External links — following a link on this site (GitHub, Ko-fi, Discord, a project page,
or media embedded in a mod description) sends you to that third party under their own policy.
What We Do Not Do
No user accounts, sign-ups, or logins.
No first-party analytics or fingerprinting scripts.
No tracking cookies.
No advertising or ad-network integrations.
No selling, sharing, or transferring of any user data — because we don't collect any.
