Summary

Flagsmith manages feature flags and remote configuration for web, mobile, and server-side applications. Teams can target releases by environment, individual user, segment, or percentage of users, and use percentage splits across variations for A/B and multivariate testing. Remote configuration lets teams change properties such as text, colors, and behavior without deploying new code. Flagsmith is available as hosted cloud, private cloud, or self-hosted software. Its 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 own 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 up to 50,000 monthly requests and one team member. If the request limit is exceeded, users have seven days to upgrade before action is taken. Paid plans start at 40.00 USD per month, billed 12 months paid up front.
