Key features
CockroachDB
Distributed SQL database built for cloud
CockroachDB offers one of the most compelling free tiers in the database market, 50M Request Units and 10 GiB storage per month with scale-to-zero is enough to run a real production app at low traffic for free.

- +PostgreSQL compatible
- +Multi-region
- +Strong consistency
- +Good scaling
Weaknesses
- -Complex operations
- -Expensive at scale
- -Learning curve
