Effector is a JavaScript library for building predictable and fast state machines and reactive applications. It provides a composable approach to handling state, where each state change is represented by an event, and each event corresponds to a specific set of state changes. Effector has a clear separation between logic and effects, making it easy to test and debug. It also has a built-in mechanism for handling subscriptions and side-effects.

Effector and Nanostores are both popular choices in the JavaScript community, but Effector has gained more traction and has a larger user base compared to Nanostores. Effector is widely adopted and actively maintained, while Nanostores is relatively newer and has a smaller community.


Effector is a feature-rich state management library with advanced capabilities, and it has a larger bundle size compared to Nanostores. Nanostores, on the other hand, focuses on simplicity and minimalism, resulting in a smaller bundle size and lower overhead.


Effector is designed to handle complex state management scenarios and provides powerful tools like reactive primitives, event sourcing, and time-travel debugging. It excels in managing large-scale applications with a high degree of complexity. Nanostores, on the other hand, is suitable for smaller projects or simpler state management needs and may not have the same level of scalability as Effector.

Developer Experience

Effector emphasizes a declarative and functional programming paradigm, making it easy to reason about and test your code. It provides good TypeScript support, and its API is well-documented and intuitive. Nanostores also offers a simple and intuitive API with good TypeScript support, making it easy to get started and maintain. However, the documentation for Nanostores may not be as extensive as Effector.


Both Effector and Nanostores are optimized for performance. Effector leverages reactive programming and fine-grained updates to achieve efficient state management. Nanostores takes a minimalist approach, reducing unnecessary re-renders and providing good performance for smaller applications. However, Effector might have a slight edge in performance due to its more extensive optimizations.

Community and Ecosystem

Effector has a larger community and a growing ecosystem, with support for React and other popular JavaScript frameworks. It has an active community maintained by the developers and offers additional tools and utilities. Nanostores, while having a smaller community, still has a supportive user base and offers integrations with frameworks like React and Svelte.
