Redefine React Component

Tired of useEffect dependency arrays, useCallback, and useMemo? You're not alone. Anchor redefines the React component by separating Logic and View. This eliminates useEffect, useCallback, useMemo, and the entire dependency array issues. No stale closures, no unnecessary re-renders—just stable references and truly fine-grained performance by default.

Scalable

Performance by Design, Not by Discipline. Anchor's fine-grained reactivity is O(1) by nature, meaning performance remains flat and predictable as your application grows.

Predictable

Reason about your code with confidence. A clean separation between a setup that runs once and a reactive view, combined with explicit lifecycles, eliminates the guesswork.

Reasonable

A Tool That Works With You, Not Against You. Architecture that respects your time. By embracing JavaScript's nature instead of fighting it, Anchor provides an intuitive, boilerplate-free experience.

Reimagine State Management

Stop thinking in setters, reducers, and selectors. Stop spreading objects just to change one field. Write state that feels like plain JavaScript—because it is. Write getters, get computed properties. Write assignments, get reactivity. Simple, predictable, and powerful.

Natural Syntax

Write state like JavaScript objects, not state machines. Direct property access and assignment. No setters, no reducers, no actions—just plain assignments that trigger reactivity automatically.

Computed Properties

Getters become reactive computed values automatically. No useMemo, no dependency arrays, no manual optimization. Just write a getter, and it computes on read—always fresh, always correct.

Flexible State Models

Mutable or immutable—your choice. Use mutable state for local component state. Use immutable state for shared stores with controlled access. Both are reactive, both give you stable references.

Core Features That Set Anchor Apart

Anchor revolutionizes state management with three powerful pillars: Fine-Grained Reactivity for unmatched performance, True Immutability for predictable state changes, and Data Integrity for reliable applications.

True-Immutability — Built for Readability, Maintainability, and Scalability

With Anchor's true immutability guarantees, state changes are explicit and predictable. This design eliminates entire classes of bugs related to unexpected mutations while making your code easier to reason about, test, and refactor as your application grows in complexity.

Data Integrity — Built for Reliability, and Safety

Anchor ensures data integrity through Zod schema validation, providing strong type safety and runtime validation. This prevents invalid data from entering your application state, ensuring reliability and safety across all components.

Declare Your State Once, Use It Everywhere

Anchor lets you define state in one place and share it across React, Vue, Svelte, and even VanillaJS — with fine-grained reactivity, true-immutability, and data integrity built in, backed with superior performance.

State Management for Humans, Built for Enterprise Scale

Anchor is built on the AX (All eXperience) philosophy - prioritizing both developer and user experience. We believe intuitive code shouldn't compromise performance, making developers productive while ensuring users get instant, responsive interfaces.

From simple prototypes to complex enterprise applications, Anchor scales efficiently with your needs. Handle massive datasets, intricate business logic, and high-frequency updates without sacrificing performance or developer experience.

Anchor vs Classic React

Both implementations follow the same development patterns with equal effort. The difference in performance comes from Anchor's optimized design, not from extreme optimization techniques. As you interact with both versions, detailed performance metrics are automatically logged to your browser's console.

Beyond Frontend: Write Once, Use Everywhere

Anchor truly lives up to its "write once, use everywhere" promise. The same reactive patterns and state management work seamlessly on both frontend and backend.

It's lonely here 😔

Experience how Anchor eliminates the traditional boundaries between client and server code with the same APIs and mental model across environments.

Make Complicated Things Simple

To build something like this, normally you'll sacrifice either UX or DX. You pick faster build - slower performance, or faster performance - slower build. With Anchor, you can have both; faster build and superior performance.
