MySQL vs PostgreSQL: Which Should You Choose?
A practical comparison of MySQL 8 and PostgreSQL 16 for bots, game servers and small apps — where each one shines, and how to pick without overthinking it.
On this page
Almost every project eventually needs a real database, and the first question is usually the same: MySQL or PostgreSQL? Both are mature, fast, free and battle-tested. For the vast majority of bots, plugins and small web apps, either one will serve you well for years. This guide cuts through the tribalism and gives you a decision you can actually make in five minutes.
The short answer
- Reach for PostgreSQL if you want the most correct, feature-rich SQL database — strong data types,
JSONB, window functions, and strict standards compliance. It’s the better default for anything data-heavy or likely to grow. - Reach for MySQL if you want the most widely supported option, especially for Minecraft plugins and PHP apps, or if your framework and hosting assume it. It’s simple, ubiquitous and extremely well documented.
If you genuinely have no preference, pick PostgreSQL — you rarely outgrow it. But don’t lose sleep over this: the differences matter far less than good schema design and regular backups.
Where each one pulls ahead
| Area | MySQL 8 | PostgreSQL 16 |
|---|---|---|
| Ecosystem / plugin support | Excellent — the default for Minecraft plugins (LuckPerms, CoreProtect), WordPress, most PHP | Excellent for apps and data work; slightly less common in the game-server world |
| JSON | Good (JSON type) |
Best-in-class (JSONB, indexing, operators) |
| Complex queries | Solid | Superior — window functions, CTEs, richer planner |
| Data integrity | Good | Stricter by default (types, constraints) |
| Extensions | Limited | Huge (PostGIS, pg_trgm, and more) |
| Learning curve | Gentle | Slightly steeper, more powerful |
Choose by what you’re building
A Minecraft server. Go with MySQL. The plugin ecosystem overwhelmingly assumes it — connecting LuckPerms, CoreProtect and friends is copy-paste. See connecting Minecraft plugins to MySQL.
A Discord or Telegram bot. Either works. If you’re storing simple key-value state or per-guild settings, MySQL is plenty. If you’re building an economy, analytics or anything with reporting queries, PostgreSQL’s query power pays off. Our guide on storing Telegram bot state walks through the trade-offs including SQLite.
A web app or API. PostgreSQL is the modern default, and most frameworks (Django, Rails, Prisma, Laravel) treat it as a first-class citizen.
Tip: Don’t run a production database off SQLite or a JSON file on an ephemeral filesystem. The moment two processes write at once — or a deploy wipes local files — you lose data. A managed database removes both problems.
What you get on Kerit Cloud
Every paid plan includes a database, so you usually don’t need to choose a separate provider at all:
- MySQL 8 on every paid plan, PostgreSQL 16 available too.
- Daily backups with non-destructive restores — a restore never overwrites your current data, so recovery can’t make things worse.
- SSL public access, so you can connect from your bot, your laptop, or a GUI client securely.
Standalone managed databases start at ₹29/month if you just need the database on its own.
Don’t over-optimise
The teams that regret their database choice almost never regret MySQL-vs-Postgres — they regret skipping backups, storing everything in one giant table, or never adding an index. Pick one, model your data cleanly, turn on backups, and move on to building the thing that actually matters.
