TeamCity
- Detailed pricing requires visiting a calculator and isn't transparent on the main pricing page.
- Self-hosted setup and agent management require more operational overhead than fully managed CI/CD services.
- Additional build agents and users are priced incrementally, which can add up for larger teams.
- The UI and configuration model have a steeper learning curve compared to YAML-first CI tools.
Flagsmith
- The Free plan supports only a single team member, limiting collaboration for small teams.
- Exceeding request limits triggers overage charges after a one-time 30-day grace period.
- Enterprise-grade SSO and governance are locked behind the Scale-Up and Enterprise tiers.
- Self-hosting requires operating and updating the platform yourself, unlike a fully managed SaaS competitor.
