cordless

Build Discord bots that run on AWS Lambda. Discord sends a request, Lambda wakes up, your handler runs, Lambda goes back to sleep. No server to keep alive, no idle cost.

import os
from cordless import Cordless

bot = Cordless(public_key=os.environ["DISCORD_PUBLIC_KEY"])

@bot.command("ping", description="Say hello")
async def ping(ctx):
    await ctx.send("pong")

handler = bot.handler()

cordless deploy --register
# → https://abc123.lambda-url.us-east-1.on.aws/

Why cordless?

Most Discord bots run as long-lived processes, a VPS or container that sits idle 99% of the time, waiting for someone to type a command. You pay for uptime whether your bot is busy or not.

cordless flips this. Your bot is a Lambda function: it only runs when Discord sends an interaction, takes milliseconds to respond, and costs essentially nothing to host. One command provisions everything on AWS: IAM role, Lambda function, public endpoint (a direct Function URL by default, or API Gateway if you want a custom domain) and registers your commands with Discord.

• No server: no EC2, no containers, no uptime monitoring, no SSH
• No idle cost: Lambda charges per invocation, not per hour
• One command to ship: cordless deploy handles all the AWS wiring
• Local dev: cordless dev runs your bot on localhost with a live public tunnel
• Slow commands: deferred interactions hand off to a worker Lambda so Discord's 3-second limit is never a problem

Install

uv add cordless   # (we should ALL be using uv)

---

Quickstart

Scaffold a new bot:

mkdir my-bot && cd my-bot
cordless init my-bot

This creates lambda_function.py, cordless.toml, and .env.example.

Configure your credentials in .env:

DISCORD_PUBLIC_KEY=your_public_key
DISCORD_BOT_TOKEN=your_bot_token

Test locally — cordless dev runs your bot with hot reload. With cloudflared installed it opens a public tunnel so Discord can reach it directly.

cordless dev

Deploy to AWS and register your commands with Discord:

cordless deploy --register
# → https://abc123.lambda-url.us-east-1.on.aws/

Paste the URL into your Discord app's Interactions Endpoint URL and your bot is live.

Please note that this is a work in progress, I have found genuine interest in serverless development and wanted an easy way to provision AWS.
