Tailslide is an open-source, lightweight, self-hosted feature flag management solution designed for organizations with a microservices architecture to easily and safely deploy new backend features with built-in circuit-breaking. Tailslide monitors the performance of feature flags and leverages a customizable circuit-breaking pattern to toggle off problematic features and direct users to a pre-defined fallback service or feature. If circuits trip, indicating that features are not working as intended - developers are immediately notified via a Slack notification, so they can respond appropriately. Tailslide speeds up the deployment cycle without sacrificing reliability.
Using Tailslide, developers can perform "dark launches" - allowing for experimentation of new features in a live production environment, where only internal test accounts or beta users are served the new feature. Tailslide also allows for the safe and gradual rollout of individual features to a subset of the user base, with the ability to easily ramp up, ramp down or shut off all traffic to a specified feature.
