Plan limits
| Resource | Free | HA Cluster |
|---|
| Databases per account | 2 | Unlimited |
| Connections per database | 5 | 100 |
| Storage | 4 GB per database | Depends on server type |
| Nodes | Shared | 1–3 dedicated |
| Backups | Not included | Daily, 14-day retention |
| Point-in-time recovery | Not included | Included |
| Monitoring | Basic | Full metrics |
| SQL Editor | Not included | Included |

Storage per server type
| Server type | Available storage | vCPUs | RAM | Price |
|---|
| Starter | 55 GB | 2 | 4 GB | $29/node/mo |
| Growth | 135 GB | 4 | 8 GB | $39/node/mo |
| Scale | 295 GB | 8 | 16 GB | $59/node/mo |
Storage listed is fully available for your PostgreSQL database. An additional 20 GB is reserved for the operating system on each node. All nodes in a cluster use the same server type.
Connection limits
| Tier | Max connections | Recommendation |
|---|
| Free | 5 | Development and testing only |
| HA Cluster | 100 | Use connection pooling for high-concurrency apps |
Connection pooling
For applications that need more than 100 concurrent connections, use a client-side connection pool:
from psycopg2 import pool
connection_pool = pool.ThreadedConnectionPool(
minconn=5,
maxconn=20,
dsn="postgresql://user:pass@host:5432/mydb?sslmode=require"
)
conn = connection_pool.getconn()
# ... use connection ...
connection_pool.putconn(conn)
const { Pool } = require('pg');
const pool = new Pool({
connectionString: 'postgresql://user:pass@host:5432/mydb?sslmode=require',
max: 20,
ssl: { rejectUnauthorized: false }
});
const res = await pool.query('SELECT 1');
// pgx pool handles connection pooling automatically
pool, err := pgxpool.New(context.Background(),
"postgresql://user:pass@host:5432/mydb?sslmode=require")
if err != nil {
log.Fatal(err)
}
defer pool.Close()
var result int
err = pool.QueryRow(context.Background(), "SELECT 1").Scan(&result)
Cluster limits
| Resource | Limit |
|---|
| Nodes per cluster | 1–3 |
| Clusters per account | No hard limit |
| Databases per cluster | No hard limit (storage permitting) |
| Extensions per database | 25+ available |
| Max vector dimensions | 16,000 (pgvector) |
Rate limits
| Action | Limit |
|---|
| API requests | 60 requests/minute |
| Cluster operations (create, scale, restore) | 1 at a time per cluster |
| Manual backups | 1 at a time per cluster |
Exceeding limits
- Storage full: Write operations will fail. Scale to a larger server type or delete unused data.
- Connection limit reached: New connections are rejected. Close idle connections or implement connection pooling.
- API rate limit: Requests return HTTP 429. Retry with exponential backoff.
