SEYFERT
Black Magic
Framework for Chads.
Discord bot framework with End-to-End Type Safety, formidable speed, and exceptional DX across runtimes.
Built Different. Built for Chads.
Same /ping command.
One side looks jacked.
Real code. Real comparison. No editing tricks. Spot the Chad.
that-library.js
// src/index.ts — every new command grows this file
import {
Client, GatewayIntentBits,
REST, Routes, SlashCommandBuilder,
} from 'that-library.js';
const client = new Client({
intents: [GatewayIntentBits.Guilds],
});
const rest = new REST({ version: '10' }).setToken(TOKEN);
await rest.put(
Routes.applicationCommands(APP_ID),
{
body: [
new SlashCommandBuilder()
.setName('ping')
.setDescription('Show latency with Discord')
.toJSON(),
],
},
);
client.on('interactionCreate', async (i) => {
if (!i.isChatInputCommand()) return;
if (i.commandName !== 'ping') return;
const ping = client.ws.ping;
await i.reply(`The latency is \`${ping}\``);
});
client.login(TOKEN);seyfert
// src/index.ts — written once. Auto-loads commands/.
import { Client } from 'seyfert';
const client = new Client();
client.start().then(() =>
client.uploadCommands({ cachePath: './commands.json' }),
);
// src/commands/ping.ts — drop file → command exists
import { Declare, Command, type CommandContext } from 'seyfert';
@Declare({
name: 'ping',
description: 'Show latency with Discord',
})
export default class PingCommand extends Command {
async run(ctx: CommandContext) {
const ping = ctx.client.gateway.latency;
await ctx.write({ content: `The latency is \`${ping}\`` });
}
}Forged for Chads.
No marketing fluff. Real features, real APIs, zero excuses.
TypeScript Maxxing
Inference everywhere. Command options, event payloads, interaction responses — all typed end-to-end. Never write `as any` again.
Built to Lift Heavy
Battle-tested on tiny bots and 7-figure guild monsters. Sharding, presence chunking, raw gateway access — pick your reps.
Decorators Do the Work
@Declare, @Options, @AutoLoad. No registration boilerplate, no manual REST.put, no slash command bookkeeping.
Hackable to the Bone
Custom cache, custom REST, custom client. Every layer is replaceable — if you need to flex on the framework itself, go ahead.
Day-1 Discord Updates
Threads, components v2, polls, interactions — supported the day Discord ships. Virgin frameworks read the changelog, Chads read the diff.
Adapter Maxxing
Official adapters drop in: Redis cache, uWS gateway, cooldown system. Modular gains — pick your stack, leave the bloat.
From Cope to W.
Three patterns. Same outcome. Spot how the second column shrinks.
// somewhere in your god-file
client.once('ready', (c) => {
console.log(`${c.user.tag} is up`);
});
client.on('guildDelete', (g) => {
cache.evict(g.id);
});import { createEvent } from 'seyfert';
export default createEvent({
data: { once: true, name: 'botReady' },
run(user, client) {
client.logger.info(`${user.username} is up`);
},
});client.on('interactionCreate', async (i) => {
if (!i.isAutocomplete()) return;
if (i.commandName !== 'pick') return;
const focus = i.options.getFocused();
const all = ['bugs', 'actions', 'random'];
await i.respond(
all
.filter((c) => c.includes(focus))
.map((c) => ({ name: c, value: c })),
);
});import { createStringOption } from 'seyfert';
const options = {
query: createStringOption({
description: 'pick one',
autocomplete(i) {
const all = ['bugs', 'actions', 'random'];
const focus = i.getInput();
return i.respond(
all
.filter((c) => c.includes(focus))
.map((c) => ({ name: c, value: c })),
);
},
}),
};client.on('interactionCreate', async (i) => {
if (!i.isChatInputCommand()) return;
// copy-pasted into every command handler
console.log(
`${i.user.username} ran /${i.commandName}`,
);
// your actual command logic...
});import { createMiddleware } from 'seyfert';
export const logger = createMiddleware<void>((m) => {
const { author, resolver } = m.context;
console.log(
`${author.username} ran /${resolver.fullCommandName}`,
);
m.next();
});
// then in command: @Middlewares(['logger'])Virgin Framework vs Chad Seyfert
Side by side. Pick your fighter.
that-library.js
Slouched. Anxious. Mid. Apologizes for every npm warning.
- ×Casts to `any` to ship faster
- ×REST.put for every command, manually
- ×47 event listeners, all wired by hand
- ×3.8 GB RAM for 50k guilds
- ×Documentation last updated in 2018
- ×Shard 0 sneezes, the bot dies
- ×Discord ships a feature → time to fork
- ×Cope.
seyfert
Square jaw. End-to-end type safety. Doesn't lose sleep over WebSocket reconnects.
- ✓End-to-end inference. Period.
- ✓Decorators register everything for you
- ✓AutoLoad scans your command tree
- ✓600 MB RAM for the same 50k guilds
- ✓Docs with runnable examples on every page
- ✓Sharding & uWS adapter ship in-house
- ✓Day-1 support for every Discord update
- ✓Pure W.
Some of the Chadest devs in our community
From devs shipping real bots. Verified W's only.
Migrated 12 commands in an afternoon. Decorators replaced 600 lines of registration boilerplate. that library that ends in .js could never.
Socram09
@socram09
The docs actually explain things. Examples for every API. Wild concept for a Discord framework in 2026.
MARCROCK22
@marcrock22
Switched from that library that ends in .js. Bot got jacked overnight — now bench presses 50k guilds on a 512MB container. No notes.
FreeAoi
@freeaoi
RAM dropped from 3.8 GB to 600 MB after porting. Same bot, same features. Felt like deleting a tumor.
Deivid
@deivid
Inference reaches into nested option objects. Auto-complete on subcommand args. I'm not going back.
JustEvil
@justevil
uWS adapter + Redis cache and my shards stopped sweating. Latency cut in half. Built Different.
Miia
@miia
Bots Built by Chads.
These bots run on pure Chad energy. Open a PR to flex your bot in the hall of fame.

I think choosing Seyfert is a very good option, we have been working with Discord.js & Discordeno for years, and yes... It's good, but for large scale bots... nothing better than Seyfert. Besides it's a team that is very attentive, and gives us a hand whenever they can..
Listen
@Listen#7518
After years of experience with Discord.js, Discordeno and Eris, Seyfert proved to be unmatched for large-scale music bots - dropping our RAM usage to under 1 GB (from almost 4 GB) while handling 200% more servers. This allowed us to finally focus on our features without any constraints over all these years.

Managing custom bots for our premium users was a major challenge—until we switched to Seyfert. It handled everything seamlessly, proving to be a powerful and reliable framework for large-scale bot deployments.

Listening to your music with an open-source solution is always a good idea. Seyfert is the best solution for that. It has a great community and is very easy to use. I love it!
Multiversal

Multiversal is a global chat bot, developed with Seyfert. Over time it has received recognition from numerous servers.
Kenium
@Kenium#9090
Open source music bot with multiple sources and free playlists. After developing on that library that ends in .js for all my projects, Seyfert provided every feature I wanted to develop a bot, while being the most resource-efficient I ever used, loved this project :D !!!
Lumi
@Lumi#4731
Lumi is a multi-funcion bot, designed to allow users to use features that would need multiple bots to do, developed with Seyfert for max optimization. I decided to change from that library that ends in .js to Seyfert because of it's optimizations and non-ram eating implementation. Would likely say to my friends to use it aswell!
