Need a PostgreSQL database for a prototype? A Redis instance for testing a caching layer? A MongoDB cluster for a coding interview? Traditionally, you'd spend 5-15 minutes provisioning cloud infrastructure, configuring security groups, and setting up credentials — only to tear it all down an hour later.

Temporary Databases on 25cent.cloud gives you a running database instance in seconds, with a connection string ready to use. When you're done, it auto-cleans itself.

Four Engines, One Interface

Choose the engine that fits your use case:

  • PostgreSQL 16 — Relational data, full-text search, JSONB, geospatial queries
  • Redis 7 — Caching, session storage, message queues, pub/sub, leaderboards
  • MongoDB 7 — Document storage, flexible schemas, aggregation pipelines
  • MySQL 8 — Traditional relational, WordPress testing, legacy app migration
All engines cost the same: 1 quarter per hour (25¢/hour). No egress fees, no storage surcharges, no per-connection pricing.

Pre-Loaded Templates

Don't start from scratch. Our templates give you a populated database in seconds:

  • E-commerce — Products, orders, customers, inventory with 500+ sample records
  • Blog — Posts, comments, users, categories with realistic content
  • SaaS — Multi-tenant schema with organizations, billing, and RBAC
  • Analytics — Time-series event data with aggregate views
  • Empty — Blank database, bring your own schema

Step-by-Step: Spinning Up a Database

  • Navigate to Temporary Databases in your dashboard
  • Select your engine (PostgreSQL, Redis, MongoDB, MySQL)
  • Choose a template or start empty
  • Set duration (1-72 hours)
  • Click "Create" — your instance is ready in seconds
  • Copy the connection string and connect from any client

Connect From Anywhere

Use standard database clients — no proprietary software needed:

```

PostgreSQL


psql "postgresql://user:[email protected]:5432/temp_abc123"

Redis

redis-cli -h db.25cent.cloud -p 6379 -a pass

MongoDB

mongosh "mongodb://user:[email protected]:27017/temp_abc123"

MySQL

mysql -h db.25cent.cloud -u user -p temp_abc123 ```

API Integration for CI/CD

The real power is in automation. Create temporary databases as part of your CI/CD pipeline:

```
POST /api/temp-database/instances
Authorization: Bearer YOUR_TOKEN
Content-Type: application/json

{
"engine": "postgresql",
"template": "e-commerce",
"duration": 2,
"enableBackup": false
}
```

Your test suite creates a fresh database, runs migrations, seeds test data, executes tests, and the database auto-cleans when done. No more shared staging databases with stale data.

Auto-Backup on Expiry

Enable auto-backup and get a SQL dump (or JSON export for MongoDB) delivered to your dashboard before the instance is destroyed. Useful for:

  • Saving prototype data you want to keep
  • Exporting demo data after a successful presentation
  • Archiving interview candidate's work

Cost Comparison

Let's compare the cost of running a database for 4 hours of prototyping:

  • 25cent.cloud: 4 quarters = $1.00 (auto-cleanup included)
  • AWS RDS: ~$0.50 + setup time + manual cleanup = at least 15 minutes of DevOps work
  • PlanetScale: $29/month minimum (MySQL only)
  • Local Docker: Free, but requires Docker setup, port management, manual cleanup
For quick, disposable database needs, the time savings alone justify the 25¢/hour cost.
