ModDex

ModDex is a Minecraft mod and modpack discovery, review, and tracking service for players comparing projects from CurseForge and Modrinth. It suits readers who want structured opinions and tools for narrowing, comparing, and organizing packs. The main trade-off is that it adds a decision layer around the two catalogs rather than replacing them as a file source.

Overview

ModDex unifies CurseForge and Modrinth catalog data behind shared search and filters for loader, Minecraft version, genre, themes, feature tags, and ratings. That is useful when a player is exploring broadly or wants consistent criteria across both services. Download buttons lead to the original project on CurseForge or Modrinth, because ModDex does not host, store, or redistribute files.

A free account is required for rating and reviewing, voting, managing a library, creating stacks, following projects, and receiving notifications. The service is web-based with an API, and supports Forge, Fabric, NeoForge, Datapack, Quilt, Paper, Spigot, and Sponge projects.

Key features

Discovery and comparison

Pack Finder recommends modpacks from preferences such as mod loader, Minecraft version, and play style. Pack Comparison places several packs side by side with ratings, tags, loaders, and other catalog data. Together, these tools reduce the work of turning a long search list into a shortlist, especially for players choosing between similarly positioned packs.

Reviews with useful context

Reviews can include an overall score plus optional Gameplay, Performance, and Aesthetics ratings. Version played, playtime, and pack version add context that makes a score more meaningful when versions or expectations differ. Reviews with screenshots, and reviews flagged by automated moderation, go through moderator review; that supports oversight but means some submissions are not immediately public.

Libraries, stacks, and alerts

The library tracks modpacks by play status and can hold notes and dates. Shareable stacks let users collect projects with notes and choose public or private visibility, making them suitable for planning a server or presenting recommendations. Users can follow projects for alerts about new written reviews, file releases, or Minecraft-version support, with optional email delivery. Project pages can also send approved review alerts to a Discord incoming webhook.

Integrations, privacy, and API

Discord webhooks are supported for review alerts, while Modrinth account linking enables developer verification and project controls. The REST API covers project data, reviews, tags, and more; public v1 endpoints require a Bearer token, and interactive documentation is available to signed-in users. Public API use is limited to personal, non-commercial purposes and cannot be used for resale, competing products, or request volumes that degrade the service.

ModDex says it does not sell personal information and supports data export and permanent account deletion. Consent-based, cookieless PostHog analytics runs on an EU instance without advertising identifiers or cross-site tracking, and is off by default in the EU and UK until opt-in. Discord webhook URLs are encrypted at rest, and the service states that it is built to comply with GDPR, ePrivacy/PECR, and CCPA/CPRA.

Pricing

Free account — free. The single plan includes catalog search, ratings and reviews, voting, library management, stacks, project following, notifications, download tracking, dependency information, mod collections, and API access. There is no free trial because the service is already free, and no paid tier is presented. Account features therefore come with the practical limits of the reputation system: stack, draft, and review-screenshot allowances vary by rank. Explorer starts with three stacks and two review images; Luminary has 20 stacks and six images. Readers who need larger allowances must build reputation rather than buy an expanded plan.

Platforms

ModDex runs on the web and provides an API. It is a catalog and organization layer; downloads open the corresponding CurseForge or Modrinth project.

Who it's for

Choose ModDex if you play Minecraft across both major mod catalogs and want one place to filter, evaluate, compare, and track projects. It is particularly useful for players assembling a pack shortlist, documenting a collection, or following projects for release and version updates. It is a weaker fit if you only need direct downloads from one catalog, want a launcher for installing packs, or need commercial API redistribution, which the terms prohibit.

Pros and cons

• Pros: shared CurseForge and Modrinth search avoids switching catalogs; contextual review scores can include gameplay, performance, aesthetics, version, and playtime; Pack Finder and side-by-side comparison support deliberate pack selection; stacks, library statuses, notes, and visibility controls help organize projects; Discord and email alerts keep users informed.
• Cons: files are not hosted, so downloading still requires the source service; account-gated features make sign-in necessary for community participation and tracking; screenshot and stack quotas depend on reputation rank; moderated submissions may wait for review; API use is restricted to personal, non-commercial purposes and includes anti-degradation limits.

Alternatives

Browse the Minecraft Mod Browsers list for other catalog options. Pick Modrinth when you want the Modrinth platform itself, including desktop platforms and the optional Modrinth+ subscription. Choose CurseForge for its direct web catalog and optional Premium tier. Agora Minecraft Mod Launcher is the better direction when a free, open-source launcher for Linux, macOS, or Windows is the priority. FreeMinecraftMods suits users creating and exporting without a build cap, while sign-in is needed to save or publish. ModBay, MineSpecs, Modhub, and modstr are free web alternatives with their own basic catalog or tool offerings.

Verdict

ModDex is a strong choice for Minecraft players who want cross-catalog discovery, context-rich reviews, pack comparison, and persistent tracking in one free account. Look elsewhere if your priority is downloading or installing files directly, using a launcher, or operating a commercial service on the API.
