Heroku Data for Redis · $150/mo (500 MB RAM)
Heroku Private-3 Redis at $150/mo is significantly overpriced for 500MB capacity. Render's Redis Starter at $10/mo offers 256MB for a fraction of the cost, though with lower specs. For workloads that truly need 500MB+ Redis capacity, neither alternative matches Heroku's tier, but Render's pricing model is far more transparent and avoids Heroku's hidden upgrade traps and tier cliffs.
Redis-compatible cache at 1/15th the price; suitable for small-to-medium workloads under 256MB.
Caveat: Only 256MB RAM vs. Heroku's 500MB; bandwidth overages and storage billed separately at $0.25/GB/month.
If your use case can substitute a relational database for Redis, this is the cheapest entry point with transparent per-GB overage pricing.
Caveat: Not a cache; shared fractional vCPU; storage and bandwidth billed separately; 99.95% SLA vs. Heroku's implicit higher tier.
