CurseForge vs Modrinth in 2026, a practical comparison

For most of Minecraft's modding history, CurseForge was the dominant platform. In the last few years, Modrinth has grown from "the new alternative" into a legitimate competitor. Both are usable. The trade-offs are real.

This article walks through them.

What each is

CurseForge is a mod hosting platform run by Overwolf. It has the largest mod and modpack library, a launcher, and integration with major launchers like ATLauncher and Prism. Long-established, well-funded, mature.

Modrinth is a younger platform, open-source-friendly, with its own launcher (Modrinth App) and its own modpack format (.mrpack). Smaller library but growing.

Both host mods, modpacks, resource packs, shaders, and worlds. Both let mod authors monetize through ads / rewards.

Library size

CurseForge has more total mods and modpacks. Roughly:

• CurseForge: well over 100,000 Minecraft projects across mods and modpacks, the largest catalog by a wide margin.
• Modrinth: a smaller catalog (in the tens of thousands), growing fast and increasingly the developers' preferred publishing target.

For most popular mods, both have them. The "first-party" mods (Create, JEI, Mekanism) are on both. The long tail is where CurseForge wins.

For modpacks, CurseForge has the bigger established names (All The Mods, Direwolf20 packs, Enigmatica). Modrinth has growing alternatives and tends to attract newer, performance-focused packs (Fabric-based packs especially).

Launchers

CurseForge App / Overwolf: the primary CurseForge launcher. Free but bundles Overwolf, which some users find heavy or invasive. Some functionality requires the Overwolf app to stay running.

Modrinth App: lightweight, single-purpose, recently solid. Loads .mrpack files, manages instances, and feels native on every OS.

Third-party launchers:

• Prism Launcher: Open-source. Supports both CurseForge and Modrinth modpacks. Recommended for users who want flexibility.
• ATLauncher: Supports both. Older interface.
• MultiMC: The pioneering third-party launcher. Largely displaced by Prism (which was forked from PolyMC/MultiMC after a licensing dispute) and no longer the community's recommended choice.

For most users, Prism Launcher is the smartest single recommendation. It works with both, has none of CurseForge's bloat, and the open-source community maintains it well.

API and tooling

CurseForge has a permissive but Overwolf-controlled API. Some operations require an API key. Some mods have been historically opt-in for distribution through third-party launchers (which caused friction).

Modrinth has an open, well-documented API. Anyone can build tools that integrate with it. Mod authors can opt in or out, but the friction is lower.

For modpack maintainers and tool builders, Modrinth's API is the friendlier choice.

Mod author experience

CurseForge:

• Larger audience.
• Established revenue model.
• Sometimes friction around how mods can be distributed.

Modrinth:

• Growing audience.
• Open-source ethos.
• Newer mod authors increasingly start here first.

Many active mod authors publish to both, with CurseForge as the "main" listing and Modrinth as a mirror. Some are Modrinth-only on principle (avoiding the Overwolf launcher).

Modpack format

CurseForge: .zip with manifest.json. Launchers download mods individually based on the manifest. Sometimes mod-specific download permissions interfere.

Modrinth: .mrpack. A clean manifest-based package: it lists every dependency by URL and hash, and the launcher downloads them at install. Generally smoother to install.

For a modpack author, .mrpack is the cleaner format. Modrinth's tooling for generating .mrpacks is straightforward.

Privacy / ethics

CurseForge has been the subject of community criticism over time:

• Overwolf integration is intrusive.
• API restrictions have rubbed third-party tool maintainers wrong.
• Some perceived monetization tensions.

Modrinth has positioned itself as the friendlier alternative:

• Open API.
• Open-source launcher.
• No mandatory background app.

These ethical considerations matter to some users a lot, to others not at all. They're real distinctions and worth knowing about.

Quick chooser

Practical recommendation by use case

"I just want to play a popular modpack."

Use CurseForge if your modpack of choice is hosted there (often the case for older established packs). Use Prism Launcher to avoid the Overwolf experience.

"I want a Fabric-based, performance-focused experience."

Probably Modrinth. Fabric and performance-focused content has gravitated there.

"I'm a mod author publishing new content."

Publish to both. Maximize audience.

"I'm making a modpack."

Make a Modrinth .mrpack first; mirror to CurseForge if you want broader reach. The .mrpack format is cleaner.

"I want one launcher that handles everything."

Prism Launcher. Open source, supports both, no surprises.

"I'm running a server based on a modpack."

The modpack's source doesn't matter for the server. Download the server pack from whichever platform hosts it. Distribute mod versions to your players who can install via whichever launcher they prefer.

Cross-platform server compatibility

A server runs Forge or Fabric, plus the mods. The launcher / platform the players use is independent of the server. Server admins don't care if their players use CurseForge App or Prism Launcher, as long as the mod versions match.

This is freeing. Don't impose a launcher on your players. Let them pick.

Specific friction points

CurseForge mods with "Project distribution restrictions":

Some mod authors set their mods to opt-out of third-party launcher distribution. This means launchers like Prism or ATLauncher can't auto-download those mods. Players have to manually grab them from the CurseForge website.

Frustrating, but manageable. Most major mods don't have this restriction.

Modrinth's smaller library on older mods:

If you want a specific mod last updated in 2021, it's much more likely to be on CurseForge only.

API key requirements:

CurseForge's API requires a developer key for some operations. Tools that don't have an approved key may fail to download mods.

A note on the future

Modrinth has grown rapidly. Its 2026 trajectory suggests continued growth. CurseForge isn't going anywhere (it has a massive moat in older content), but the new content is increasingly split.

A reasonable bet: 5 years from now, Modrinth will be a peer to CurseForge, and Prism will be the standard launcher. We're not there yet, but the direction is clear.

Conclusion

Both platforms are usable. CurseForge has more content and the established names. Modrinth has cleaner tooling and a friendlier API. Use Prism Launcher to access both without committing.

For most players, the choice is "use what hosts the modpack I want." For mod authors and modpack creators, lean toward Modrinth-first publishing with CurseForge as a mirror.

No platform is bad. Pick what fits, and don't get tribal about it.
