Flagsmith manages feature flags and remote configuration for web, mobile, and server-side applications. Teams can target flags by environment, individual user, segment, or percentage of users to release changes gradually. Multivariate flags support percentage splits for A/B and multivariate testing, while remote configuration lets teams change properties such as text, colors, and behavior without deploying new code. Deployment choices include hosted cloud, private cloud, and self-hosted. Listed integrations include Amplitude, Datadog, GitHub, GitLab, Grafana, Jira, Mixpanel, OpenFeature, Segment, Sentry, Slack, and Terraform; environment-level webhooks can send events to a team's infrastructure. The maker says core feature-flag functionality is open source and most of the product is under the BSD-3 licence. The free plan includes 50,000 monthly requests and one team member. Exceeding the free request limit gives users seven days to upgrade before action is taken. Paid plans start at 40.00 USD per month, billed 12 months paid up front.

Who it is for

Flagsmith suits development teams that need controlled feature releases, remote configuration, or a choice of hosted and self-hosted deployment. Its free plan may suit a small team that stays within the 50,000-request monthly limit.
