Description

Flagsmith gives software engineering teams a self-hosted or fully managed feature flagging platform for controlling releases across web, mobile, and backend systems. Ship code behind a flag, then decide who sees it — by environment, user, or custom segment — without redeploying. Run Flagsmith however fits your infrastructure: our managed cloud, your own private cloud, or fully on-premise. What you get: Progressive rollouts with one-click rollback if something breaks Live config changes — flip features on or off instantly, no redeploy required Segment-based A/B and multivariate testing Project and role-based access control for multi-team organizations Native integrations with the tools already in your stack MCP support and a CLI so AI agents and scripts can manage flags directly Open source at its core, Flagsmith is built for teams that want control over where their configuration data lives.

Description

SignaKit serves as a comprehensive platform for engineering teams, providing features like feature flags, A/B testing, and experimentation, which empower them to manage software releases effectively without the constraints of per-seat fees or vendor lock-in. The evaluation of flags takes place locally within the application process, utilizing a cached configuration delivered via AWS CloudFront, ensuring swift sub-millisecond evaluations that eliminate the need for network roundtrips during critical operations. Additionally, the bucketing mechanism is deterministic through the use of MurmurHash3, guaranteeing that users consistently receive the same variant across different sessions and devices. Teams have the capability to implement both boolean and multivariate flags, configure percentage rollouts, target audiences based on various user attributes, and activate instant kill switches for immediate rollbacks in urgent situations. The integrated A/B testing feature assesses statistical significance with customizable experiment snapshot intervals, while the multi-armed bandit optimization feature adeptly directs traffic towards the winning variant as data is gathered — all of these functionalities are available on every plan, including the Free option. This makes SignaKit an ideal solution for teams seeking flexibility and reliability in their software release processes.

Product Features

AB Testing

Flagsmith serves as the experiment bucketing engine, allowing you to maintain your existing analytics setup seamlessly. With Flagsmith, you can create a multivariate flag and assign percentage weights to different variants, enabling deterministic traffic distribution. Bucketing occurs on an individual basis, ensuring that each user consistently receives the same variant until you choose to adjust the weights. Target specific user groups for your tests using segments, whether based on subscription tiers, geographic regions, or early access beta groups. This same feature can be leveraged for beta programs to gather initial feedback. Importantly, Flagsmith does not track events or analyze significance. Instead, simply forward the variant name to your preferred analytics platform. It integrates effortlessly with tools like Amplitude, Mixpanel, Segment, Heap, and Rudderstack, or you can connect it to your own data pipeline via webhooks. This consolidates your metrics into a single source of truth. Whether you utilize our cloud services, your private cloud, or an on-premise setup, Flagsmith delivers consistent performance.

Feature Management

Implement a feature toggle, deploy the code, and determine visibility later on. Each environment can have the same toggle configured with different states, eliminating the need for redeployment to alter behavior in the live environment. The targeting options encompass boolean toggles, multivariate toggles, remote configuration values, user identities with attributes, segments created from rules based on those attributes, and percentage-based rollouts for canary deployments. For evaluation purposes, Flagsmith provides server-side SDKs that operate in local evaluation mode, allowing flags to be resolved within the process without the need for a network call for each check. The Edge API delivers client and mobile SDKs from the nearest geographic location. Offline mode is available for environments lacking outbound connectivity. There are over 15 open-source SDKs available, including those for TypeScript, Python, Java, C#, Go, Ruby, PHP, Swift, Kotlin, and Flutter. Governance capabilities feature audit logs, role-based access management, approval workflows for change requests, scheduled updates, SAML SSO, and SCIM provisioning. Automation can be achieved through the REST API and Terraform integration.
