discord.py vs discord.js: which should you use for your bot?
An honest comparison of the two most popular Discord bot libraries: language, learning curve, slash commands, ecosystem and hosting needs.
Both libraries can build the same bots: slash commands, buttons, moderation, music, dashboards. The real difference is the language you're happier writing.
Side by side #
| discord.py | discord.js | |
|---|---|---|
| Language | Python | JavaScript (or TypeScript) |
| Packages file | requirements.txt | package.json |
| Slash commands | app_commands plus tree.sync() | Builders plus a REST deploy script |
| Style | Decorators, cogs, async/await | Event listeners, handlers, async/await |
| Good if you | Know Python or are new to coding | Know JavaScript or web development |
Pick discord.py if… #
- You already write Python, or you're learning to code. Python reads close to plain English.
- You want cogs to split a bigger bot into files without much setup.
- You want to use Python libraries for data, images or AI APIs in your commands.
Pick discord.js if… #
- You know JavaScript or plan to build a web dashboard in the same language.
- You like TypeScript and strong editor autocomplete.
- You want the npm ecosystem for your bot's features.
Does it change hosting? #
Not much. Both run 24/7 on a small bot plan; memory depends more on caches and intents than on the language (see bot RAM). On ESN, pick a Python or Node.js bot server, upload your files, and the server installs your packages on start:
Other options #
Java (JDA), C# (Discord.Net), Go (discordgo) and Rust (serenity) are popular too. ESN runs Java bots and 29 more languages.
