Where can I host a Discord music bot for free?

Pick Music Bot in the panel (Bots, Host a bot, Discord bot) and paste your bot token. It plays direct links to audio files and internet radio streams in your voice channels, keeps a queue, and answers /play, /radio, /skip, /pause and /queue; /testsound plays a short chime to check that voice works. /autoplay keeps it in a channel you pick: it starts the moment someone joins and streams nothing while the channel is empty.

It runs on discord.js 14 and @discordjs/voice 0.19 with DAVE, the end-to-end encryption Discord requires on voice. The source is public: read it, fork it, or hold it next to your own bot when voice will not connect.

discord.js with @discordjs/voice, discord.py with voice extras, Lavalink-based bots: the runtime has FFmpeg, libopus and libsodium, so voice works without installing anything. A bot that plays in many servers at once does better with Lavalink, which runs as its own app (one click from the app catalog on a Starter plan, from the official image) with the bot pointed at it over the private network.

Discord closes voice connections from libraries without DAVE with close code 4017, before any audio is sent. If your bot loops between signalling and connecting and then times out, update @discordjs/voice to 0.19 or newer and remove any daveEncryption: false. Nothing on FadeHost blocks the voice ports.

Their terms do not allow bots to stream from them, and playback from data centre addresses is blocked more every year, so a bot built on them stops working without warning. The ready-made bot plays what you are entitled to use: direct links to audio files, internet radio, your own files on a web host. If you run your own music bot with sources you are entitled to use, it runs fine here; we just do not build one on the others.
