Folia and Paper: Skyblock Server Trends in 2026
Folia and Paper are the two dominant server software options for Skyblock in 2026, and the gap between them is narrower than ever. Paper remains the industry standard for stability and community support, while Folia's regional multithreading is finally mature enough for production servers. Here's what's actually changed.
What Are Folia and Paper, Anyway?
Paper is the high-performance Spigot fork that's been the workhorse of multiplayer Minecraft since around 2015. It's essentially vanilla Minecraft but optimized for servers, cutting unnecessary calculations without breaking plugins or breaking gameplay mechanics. Here's the thing, most big Skyblock networks run Paper because it just works.
Folia is Paper's next-generation approach. Instead of squeezing performance from a single server thread, Folia splits the world into regions and lets your CPU handle multiple regions simultaneously. Only catch: it's newer, and not every plugin supports it yet.
Actually, that's not quite fair anymore. As of late 2025, Folia stabilized enough that several major Skyblock networks made the jump to production.
The practical difference? Paper gives you maybe 30-40% performance gains over vanilla. Folia can deliver 100%+ on servers with high player counts. But multithreading introduces its own complexity - you need plugins designed for it.
Why Skyblock Servers Need This
Skyblock is fundamentally different from survival servers from a performance perspective. Instead of everyone sharing one world, each team gets isolated islands. That's thousands of mini-worlds running simultaneously on a single server. Performance matters exponentially.
Heavy Skyblock servers - the kind running 100+ concurrent players with complex island automation - hit a wall with vanilla Minecraft pretty fast. Paper gets you to maybe 80 players before lag becomes painful. Folia can push that closer to 150-200 before you see serious issues.
Island-specific mechanics add pressure too. Farms generate lag. Mob grinders generate more. Redstone contraptions generate even more. Paper handles this reasonably well by optimizing globally. Folia handles it better because each island's lag is isolated to its own thread - your megafarm on one island won't tank performance for everyone else.
Paper's Still Winning on Compatibility
Paper's been the de facto standard for nearly a decade. It has near-universal plugin support.
Want to run a Skyblock server with custom quests, economy plugins, rewards systems, cosmetics, everything? Paper lets you do it. The community is enormous. You'll find tutorials, troubleshooting guides, and experienced admins answering questions everywhere.
When something breaks, someone's already fixed it. When a new Minecraft version drops, Paper updates within days. When you hit a weird bug, there's a Discord server full of people who've encountered it.
And it's predictable. You know exactly what you're getting. No surprises. Paper is the safe choice. For very good reason.
But Folia's Moment Arrived in 2026
I mentioned Folia got stable in late 2025. Here's the actual story: 2026 is when adoption shifted from "interesting beta" to "legitimate choice."
By mid-2026, the plugin ecosystem followed. Essentials works. LiteBans works. Economy plugins work. Even CitizenS, Placeholders, and most modern Skyblock-specific plugins have Folia compatibility patches. The ecosystem finally caught up.
More top-tier Skyblock networks went all-in on Folia. When established servers with thousands of players make the jump, the community notices. That's a signal.
One real caveat though: older plugins, niche community addons, or heavily customized codebases still struggle sometimes. If you're running something obscure or completely custom, test thoroughly first. Don't migrate your live server and hope for the best.
What's Trending According to Real Data
Most top Skyblock servers on our Minecraft server list are still running Paper. But that's partly momentum. The networks actively scaling, adding players, or implementing new features? They're testing Folia or already running it.
Regional multithreading went from theoretical to practical. The conversation shifted from "is it worth it?" to "when should we switch?"
Here's the current breakdown based on what I'm seeing across communities:
- Under 50 concurrent players: Paper is totally sufficient. Don't bother migrating.
- 50-150 players: Paper works fine, but Folia is worth testing on a development server.
- 150+ players: Folia becomes genuinely important unless you want constant lag complaints.
If you're actually considering the migration, grab our server properties creator tool and use the Folia-optimized templates. They exist specifically because enough admins asked for them.
The Migration Reality Check
Switching sounds simple in theory.
Drop in Folia, restart the server, celebrate your new performance, right? Reality is messier. You'll need to:
- Back up everything (non-negotiable).
- Test on a dev server with your actual world and plugin load.
- Handle incompatibilities as they surface (and they'll).
- Reconfigure some server properties - worldborder behavior changes, certain async operations behave differently.
- Monitor closely for subtle issues - chunk loading edge cases, command execution timing, entity behavior differences.
Most migrations take 2-4 hours if you've done this before, or 2-4 days if it's your first time. The actual migration is quick. But that testing and troubleshooting takes time.
Paper's documentation covers Folia migration pretty thoroughly now, which wasn't true even six months ago. Use it. Also check the Minecraft Text Generator if you need to build custom messages or command feedback - some text rendering behaves slightly differently under Folia.
The Ecosystem Is Still Stabilizing
Here's what's actually happening right now. Major plugin developers - the ones making economy systems, cosmetics, custom mechanics - are prioritizing Folia support. Smaller developers still mostly focus on Paper.
That gap shrinks every month. By 2027, "does it support Folia" probably won't be a question anymore. It'll just be expected.
But we're not there yet.
If you're running a Skyblock server and considering this, check your plugin list against the Folia compatibility tracker. It's not perfect, but it covers most mainstream stuff. Run it in development mode first. Test world generation, chunk loading, plugin commands, everything.
The beautiful thing about Paper and Folia both being free, open-source software is that you can actually do this. Try it. Worst case, you shut it down and go back to Paper. Best case, you unlock real performance gains.
