Gotchas
- One free web Service
Only a single 'free' instance type is included per organization; additional instances are pay-per-use.
- One free PostgreSQL database
Only one free Postgres database is included per organization.
- 5 active hours/month for free Postgres
The free PostgreSQL database is limited to 5 hours of active time per month, making it unsuitable for continuous workloads.
- 100 GB outbound bandwidth/month
Free tier includes 100 GB of outbound bandwidth per month; overages will cost $0.04/GB once Koyeb begins charging.
- 0.1 vCPU / 512 MB RAM
The free instance is limited to 0.1 vCPU and 512 MB RAM, shared resources not suitable for CPU-intensive or memory-heavy applications.
- Frankfurt, Washington D.C., or Singapore regions only
Free instances are restricted to three regions (Frankfurt, Washington D.C., and Singapore); other global regions require a paid plan.
- No priority support
Free tier (Starter plan) does not include priority or business-hours support; paid Pro/Scale plans are needed for support.
- No scale-to-zero / spending limits
Scale-to-zero and spending limit features are not yet available on any plan, limiting cost-control options.
- Credit card required for all accounts
Koyeb requires a valid credit card to prevent fraud and abuse, even for free-tier usage; a $29 pre-authorization hold is placed and immediately cancelled during verification.
- No high availability or multi-instance
Free tier is limited to a single instance with no HA replication or autoscaling, making it unsuitable for production reliability requirements.
