Server Compatibility

Velocity is compatible with many Minecraft server implementations. The expectation is that if the server acts like Vanilla, Velocity will work, and we make special provisions for modded setups where we can.

Compatible game versions

As of this writing, Velocity is compatible with Minecraft 1.7.2 through .

Vanilla setups

Velocity is best-tested with implementations derived from the Vanilla server by Mojang that do not add content to the game itself.

Vanilla servers

The Mojang Vanilla software is in a complicated position. It is useful as we often produce protocol updates using the Mojang server for testing, but in production setups, the lack of player info forwarding support can induce subtle client problems.

If you plan to run a Vanilla server, the Velocity team strongly recommends that you use Fabric with the FabricProxy-Lite mod. Fabric and FabricProxy-Lite do not by themselves change the Vanilla experience, and your server will remain compatible with Vanilla clients. If you are unable (or unwilling) to run Fabric, VanillaCord allows you to use legacy BungeeCord forwarding.


Spigot is not well-tested with Velocity. However, it is based on Vanilla and as it is the base for Paper, it is relatively well-supported.

Spigot does not support Velocity's modern forwarding, but does support legacy BungeeCord forwarding.


The Velocity project recommends using Paper for running a public server. Velocity works with all versions of Paper from 1.7.10 to the latest version.

You can use Velocity's modern forwarding if you run Paper 1.13.2 or higher. If you use Paper 1.12.2 or lower, you must use legacy BungeeCord-style forwarding.


SpongeVanilla is compatible with legacy BungeeCord-style and modern forwarding. Our Sponge support largely focuses on Forge compatibility, see below for more information.

Modded setups


Velocity works with Fabric out of the box, but you should add support for player info forwarding using a mod like FabricProxy-Lite (which supports Velocity modern forwarding).

In addition, if you intend to run mods that add new content on top of Vanilla, you should install CrossStitch, which improves support for certain Minecraft features that are extended by mods, such as custom argument types. This mod is officially maintained by the Velocity project.

Minecraft Forge (1.13 and above)

Velocity as of version 3.3.0 supports Forge servers of versions higher than 1.20.2. Support for intermediate versions between 1.13 and 1.20.1 is not planned, however, you can use the Ambassador plugin to support these versions.

To add modern forwarding support to Forge, you must install the ProxyCompatibleForge or SpongeForge mod corresponding to your server version. Note that SpongeForge is currently in an experimental phase of its Forge support for 1.20.4 versions.

Minecraft Forge (1.7.2-1.12.2)

Minecraft Forge for Minecraft 1.7.2-1.12.2 is fully compatible with Velocity, as we make special provisions to synchronize client state with each server. However, we strongly recommend the use of SpongeForge, as it allows you to use legacy BungeeCord player info forwarding and generally improves proxy support in general.

Velocity does not support Forge-Bukkit hybrids - they have caused several issues, and the design of the Bukkit API precludes any notion of sane mod support.

Proxy-behind-proxy (BungeeCord/Waterfall, Velocity, ...)

These setups are completely unsupported. You are best advised to avoid them, as they can cause lots of issues. Most proxy-behind-proxy setups are either illogical in the first place or can be handled more gracefully by better, more scalable and performant solutions.

Other implementations

This is, naturally, not an exhaustive list. Alternative implementations of the Minecraft protocol may or may not work. We encourage you to experiment and to contribute back with your results.
