A Discord or Telegram bot has one hard requirement that surprises most first-time builders: it must be online 24/7, or the community notices. Running it from your laptop means it dies with the lid closed. A budget VPS at $4–$6/month is the cheapest reliable home for a bot, and the resource requirements are far smaller than most people assume. Here are the real numbers.
Discord vs Telegram: the platform changes the math
The two platforms impose very different footprints. A Discord bot keeps a persistent gateway connection and caches guilds, channels, and users in memory — the bigger your servers, the bigger the cache. Telegram bots are stateless by comparison: they poll for updates or receive webhooks, so memory stays flat and a bot can run on as little as 256MB. If you are targeting the smallest possible VPS, Telegram is the friendlier platform. Discord is still perfectly viable on 1GB — just don’t plan to join a few hundred servers on one process.
Real resource usage for a typical bot
Measured on production bots, the memory footprint depends mostly on the language and libraries, not the features:
| Stack | Idle RAM | Peak RAM | CPU |
|---|---|---|---|
| Python (discord.py / aiogram) | 80–200MB | 250–400MB | <5% of one core |
| Node.js (discord.js / telegraf) | 150–300MB | 400–600MB | <5% of one core |
| Go or Rust bot | 30–80MB | 150–300MB | Near zero idle |
| Plus SQLite database | +20–100MB | +100MB | Bursts on writes |
Idle CPU is essentially zero; bursts happen when commands run, images are processed, or messages are sent in bulk. A single vCPU is more than enough for anything short of a large music or image bot.
What to look for in the plan
- 1GB RAM minimum — 2GB if you run multiple bots or a database alongside
- 1 vCPU — fine for the vast majority of bots
- SSD storage — 20GB is plenty; NVMe keeps the bot snappy
- 1TB of bandwidth — a busy bot uses a fraction of this
- A dedicated IPv4 — needed for outbound API calls and webhooks
- A provider with decent uptime history — the bot inherits the server’s reliability
Uptime history matters more than any single spec, and it is the hardest number to verify from a sales page — the reliability notes in our budget VPS comparison table cover it for the major budget providers.
The cost comparison
Cheaper-sounding alternatives usually fail on one axis or another:
| Option | Monthly cost | The catch |
|---|---|---|
| Home PC / Raspberry Pi | $5–$15 electricity | Downtime, dynamic IP, home network outages |
| Free cloud tiers | $0 | Sleep timers, cold starts, usage caps, ToS limits |
| Bot-specific hosts | $2–$10 | Locked-in, limited to one bot type |
| Budget VPS | $4–$6 | You handle setup — but you get full control |
Setup that keeps the bot alive
A bot that crashes every night is a bot that gets replaced. Five minutes of setup prevents that. Run it as a systemd service with automatic restart — a minimal unit file looks like this:
[Unit]
Description=My Discord bot
After=network-online.target
[Service]
User=bot
WorkingDirectory=/opt/bot
ExecStart=/usr/bin/python3 /opt/bot/main.py
Restart=always
RestartSec=5
[Install]
WantedBy=multi-user.target- Add 1–2GB of swap as a buffer against memory spikes
- Set a free uptime monitor with a webhook alert to your own bot or email
- Back up the code, the
.envtoken file, and the SQLite database daily to offsite storage - Keep dependencies updated monthly — bots are a favorite target for credential scraping
Mistakes that kill bots
- Running as root — a compromised bot means a compromised server; use a dedicated user
- Committing the bot token to git — rotate it the moment it touches a public repo
- No auto-restart — crashes are normal; staying down is a choice
- No swap — memory spikes that OOM-kill the process are the #1 cause of “it was working yesterday”
- Caching everything — libraries that cache aggressively can double memory use on large guilds
- Free-tier hosting — sleeping instances and ToS limits are incompatible with a 24/7 bot
When you need more than the base plan
Most bots never outgrow a 1GB VPS. You move up when you hit real limits: sharding a large Discord bot across processes, heavy image or audio processing, many concurrent commands, or a MySQL database with serious history. Even then, a 2GB / 2 vCPU plan — still under $10/month — covers nearly everything short of a commercial-scale service. Location matters more than most bot guides admit: a VPS in the same region as the platform’s API endpoints shaves 10–30ms off every command — imperceptible to users, but it reduces timeout-related errors during command bursts. More importantly, pick a provider with a verifiable uptime record, because platform gateways penalize bots that flap offline and reconnect repeatedly, and a flaky host makes a well-written bot look like a misbehaving one. Vultr bills hourly, which makes it painless to test a bot before committing, and InterServer offers a flat-rate $3 entry plan for simple bots. Compare both against other budget options in our budget VPS comparison table.
The bottom line
A Discord or Telegram bot is one of the best workloads for a budget VPS: tiny resource footprint, modest bandwidth, and a hard requirement for uptime that only a real server satisfies. A $4–$6 plan with a systemd service, swap, and an uptime alert will outlive every laptop and free-tier experiment you can throw at it.
