Does every Redis command work?

It implements a practical subset: strings, hashes, lists, sets, sorted sets, keys, expiry, and basic server commands. Uncommon commands return an 'unknown command' error.

Is the data persisted?

No. The store lives only in this browser tab for the session. Refreshing or closing the tab clears it, and nothing is sent to a server.

Can I connect it to a real Redis instance?

No. It is a self-contained simulator for learning and prototyping, not a client for a live server.

About this tool

Run Redis commands in your browser: strings, hashes, lists, sets, sorted sets, keys and expiry. Learn and test Redis with no server or signup. Free online simulator. Redis CLI Simulator runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

Redis CLI Simulator is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.

How do I use this tool?

How do I use Redis CLI Simulator?
Open Redis CLI Simulator, enter or paste your input, and copy the result. The page works without an account.

Learn Redis Without Installing Anything

A hands-on tour of the Redis data structures you'll actually use — strings, hashes, lists, sets and sorted sets — with copy-paste commands you can run in your browser right now.

2D Fluid Dynamics & Particle Physics Sandbox

A physics playground with two engines sharing one canvas. The fluid mode runs a real Eulerian Navier-Stokes solver — semi-Lagrangian advection, explicit diffusion, Jacobi pressure projection and vorticity confinement — that you paint with dye and velocity using mouse or touch. The particle mode is a damped Verlet N-body engine with gravity wells, Coulomb attractors and repulsors, spring links, wall restitution and elastic circle collisions. Particle counts adapt to the device (100k target on WebGL2 desktop, 2k-5k on CPU fallback), and every configuration exports as runnable code: a Matter.js world, a PixiJS ticker setup, or a standalone vanilla Canvas engine.

AI Function Calling Schema Generator

Generate function calling JSON schemas from TypeScript interfaces

Algorithm Arena & Data Structure Visualizer

Interactive arena for algorithms and data structures: eight sorting algorithms racing on one seeded input, six pathfinding algorithms walking generated mazes, and BST, AVL, Red-Black, B-tree, heap and trie operations replayed step by step with rotations highlighted. Every run shows the Big-O table and the phase-highlighted reference implementation in four languages, and compared values can be played as pitch (sonification) through the shared audio engine. Everything runs client-side; inputs never leave the browser.
