Flagsmith
Open-source feature flags and remote config with straightforward self-hosting.
What it is
Flagsmith provides feature flags, remote configuration, segments and A/B testing with SDKs for the major languages, available as SaaS, private cloud or fully self-hosted via Docker or Kubernetes. Its scope is deliberately narrower than the analytics-heavy platforms.
Best for
Where it is strong
- Genuinely easy self-hosting with a Docker image and Helm chart.
- Simple, comprehensible pricing.
- Remote config alongside flags, which covers a lot of mobile use cases.
Where it falls short
- Experimentation features are basic.
- Smaller company and community than the leaders.
- Fewer governance controls for large organisations.
Pricing
From $40 per month (Start-Up, billed yearly; $45 monthly)
Free tierFree tier: Free cloud tier with a monthly request allowance; open-source self-hosting is unlimited.
What drives the bill: Free covers 50k requests a month and one seat; Start-Up raises that to 1M requests and 3 seats, Scale-Up is $250/month yearly. Considerably cheaper than LaunchDarkly, and self-hosting removes usage pricing entirely.
