| Deployment | Datafiles are served from the customer’s own CDN, with no vendor in the request path. | Flagsmith offers hosted cloud, private cloud, and self-hosted deployment options. |
| Experiments | Features can define weighted string variations for A/B and multivariate experiments. | Multivariate flags support percentage splits across variations for A/B and multivariate testing. |
| Feature flags | Boolean flags use ordered targeting rules whose first matching rule determines the result. | Flags can be boolean or multivariate and decouple deployment from release. |

In their own words
Featurevisor
Featurevisor is a Git-based tool for managing feature flags, experiments and remote configuration through YAML files in a Git repository. Teams build datafiles for each environment, deploy them and evaluate features through an SDK. Rules can target users in order, roll out a percentage and assign weighted experiment variations. Typed global and feature variables allow defaults and targeted overrides, with schemas validated during datafile builds. Applications fetch static JSON datafiles and evaluate flags locally in memory, without a network request for each decision; the datafiles are served from the customer’s own CDN. YAML test specifications can check expected behavior locally or in CI, with failed assertions returning a non-zero exit. Git pull requests and CI linting, tests and builds provide change control. Featurevisor is self-hosted and MIT-licensed. Its free plan is free, with no per-seat pricing or evaluation service to keep running. Listed platforms include Android, iOS, Linux, macOS, web and Windows.
Flagsmith
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, and split users across variations for A/B and multivariate tests. Remote configuration lets teams change properties such as text, colors, and behavior without deploying new code. Deployment options include hosted cloud, private cloud, and self-hosted. Its 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 uses the BSD-3 licence. The Free plan includes 50,000 monthly requests and one team member; after exceeding the request limit, users have seven days to upgrade before action is taken. Paid plans start at $40 a month, billed 12 months paid up front. Platforms include Android, API, iOS, Linux, macOS, self-hosted, web, and Windows.
