Valkey is an open-source in-memory data store maintained under the Linux Foundation. It supports Redis-compatible commands and structures including strings, hashes, lists, sets, sorted sets, and streams.
Use this playground to test SET, GET, hashes, lists, sets, counters, expiry, transactions, and streams without installing Valkey or connecting a client.
This page sends your script to a hosted, network-isolated Valkey 9.1.1 runtime. Every Run executes the whole editor contents against a fresh database, then discards its database state and files. It does not run the database in your browser and it never connects to your own database.
Available output: Valkey CLI text, newline-delimited JSON, and CSV streams. The schema panel shows a bounded catalogue captured after successful execution. Large output may be truncated, and package installation, remote network access, persistent storage, and external database connections are not supported.
Build a Valkey script in the editor with syntax highlighting and editor assistance.
Run the complete script against a fresh isolated database sandbox.
Review rows, messages, errors, and execution time in the results panel.
Your draft stays in this browser, and Share creates a separate snapshot link.
