Free Managed MySQL Cloud Databases for Testing & Development
Instantly spin up isolated MySQL database environments, secure schemas with custom credentials, whitelist connection hosts, and track connection loads without any VPS manual server steps.
Relational SQL Hosting Built for Developers
We provide dynamic user accounts, database schemas, and whitelist firewalls to ensure your database operations are simple, fast, and secure.
Dynamic Isolation
Every database runs with a randomized, owner-specific MySQL user account (e.g. `nm_root_...`) to hide identities and protect connection safety.
IP whitelist Firewalling
Decide who can connect. Whitelist your local home IP or application servers, or toggle off unrestricted remote access (`%`) with a single click in the control panel.
Dedicated Port 4406
Bypasses standard port restrictions and security overlays by hosting all user schemas on a custom port `4406` mapping to `courseexe.com`.
Unified Global Quota
Your relational database storage is calculated as part of your global 100MB/1GB account storage limit, allowing flexible data allocation.
Automated Health Checks
Real-time connectivity pings, read-write safety tests, and size check indicators verify that your database schemas remain healthy and online.
Active Connection Metrics
Audit concurrent database sessions per whitelisted IP. Monitor connection limits (capped at 15 max connections) to optimize load handling.
Frequently Asked Questions
Is this database hosting really free?
Yes! Every registered user on courseexe.com gets access to provision up to 2 active MySQL databases alongside their MongoDB database clusters.
How is the storage limit enforced?
MySQL database storage is part of your global storage quota (e.g. 100MB). If your cumulative usage (emails + MongoDB + MySQL) exceeds your limit, your MySQL database is temporarily locked to Read-Only mode to protect server resources. Once usage drops, full read-write access is restored automatically.
Can I connect using desktop clients?
Absolutely. You can connect using DBeaver, MySQL Workbench, TablePlus, or any CLI shell using the provided Host (`courseexe.com`), Port (`4406`), and credentials. Make sure you whitelist your public client IP address in the Allowed Hosts table.
