Paper vs Spigot vs Purpur vs Folia - Which Minecraft Server Software is Best in 2026?

Spigot was the first major performance fork of CraftBukkit and remains the foundation that Paper is built on. Plugin compatibility is nearly 100% - almost every Bukkit plugin works on Spigot without issues. Performance is better than vanilla Minecraft but significantly behind Paper and its forks. For small servers (under 10 players) with simple plugins, Spigot is functional but not optimal. The PaperMC team explicitly recommends Paper over Spigot for all use cases - Paper includes hundreds of optimizations while maintaining Spigot plugin compatibility. There is no performance advantage to using Spigot over Paper; move to Paper for immediate TPS improvements with zero plugin migration.

Paper is the flagship project of PaperMC and the most popular server software in 2026, used by 70%+ of public Minecraft servers. The official Paper documentation at docs.papermc.io covers extensive performance optimizations: optimized chunk loading with asynchronous chunk generation, entity activation range control preventing distant mobs from consuming CPU, efficient redstone processing with configurable implementation modes (VANILLA, ALTERNATIVE_CURRENT, EIGENSPACE), built-in Anti-Xray with multiple engine modes, per-player mob spawns for fair mob distribution, and extensive API for developers (Component API for chat, Command API using Brigadier, Entity API for teleport and pathfinding). Plugin compatibility is excellent - Paper is designed as a drop-in replacement for Spigot. The Paper docs recommend using Aikar's flags for JVM optimization and provide detailed global and per-world configuration references. For 90% of server owners, Paper is the right choice.

Purpur is a fork of Paper that maintains identical performance while adding hundreds of additional gameplay configuration options. Where Paper focuses on performance, Purpur extends Paper with configurable mechanics: allow entities to ride entities of any type, disable or modify specific enchantments, configure dolphin speed and ender dragon behavior, control mob griefing (creeper explosions, enderman block pickup), adjust anvil and enchanting costs, and hundreds more gameplay tweaks accessible through a single purpur.yml configuration file. Performance is identical to Paper since Purpur uses the same optimization patches without adding overhead. Choose Purpur if you want fine-grained gameplay control without installing extra plugins. It is especially popular for SMP servers that want custom mechanics without mods. Switch between Paper and Purpur with one click from the CyberNex control panel.

Pufferfish is a fork of Paper focused on extreme optimization for large servers. It includes additional optimizations beyond Paper: parallelism for entity ticking (processing entities across multiple threads), simulated player system for efficient mob spawning, aggressive entity activation management, and further tick loop optimizations. Performance gains over Paper are 5-15% depending on server type and player count. Tradeoff: some mechanics behave differently - mob farms may have slightly lower spawn rates, entity behavior prioritization can change, and lag compensation may feel different in combat. Pufferfish is best for large public servers (50+ players) where every TPS point matters and minor gameplay deviations are acceptable for the performance gain.

Folia is PaperMC's experimental project that adds regionized multithreading to the Minecraft server. Unlike all other server software which runs the main game loop on a single thread, Folia splits the world into independent regions and processes each region on its own thread. This means Folia can utilize ALL CPU cores simultaneously - a 16-core processor can genuinely process 16 regions in parallel. The implications are massive: 200+ player servers become practical, large modded worlds load dramatically faster, and CPU bottlenecks are significantly reduced. However, Folia is still experimental and has important limitations: plugins must be specifically updated for Folia's threading model (traditional plugins that assume single-threaded execution will break or cause data corruption), cross-region interactions (entities moving between regions) have inherent delays, and the plugin ecosystem is small compared to Paper. Folia is not recommended for general use yet - it is for large server networks willing to invest in Folia-compatible plugins and testing. Monitor PaperMC's official Folia documentation at docs.papermc.io/folia for updates.

Start with Paper - it is PaperMC's flagship recommendation, has the best balance of performance, compatibility, and community support, and is backed by the most comprehensive official documentation at docs.papermc.io. If you need extra gameplay features without plugins: switch to Purpur (identical performance to Paper). If running 50+ player public servers needing every optimization: test Pufferfish. If running a massive network (150+ players) with development resources: evaluate Folia with Folia-compatible plugins. Avoid Spigot unless you have a specific legacy plugin that doesn't work on Paper - and even then, check the Paper docs for alternatives. All five server types run on CyberNex hardware and you can switch between them from your control panel with one click.
