CyberChef on Ubuntu 24.04 LTS | cloudimg

CyberChef is the Cyber Swiss Army Knife: an open source web app, originally created by GCHQ, for carrying out a huge range of cyber operations inside a web browser. Operations, called recipes, cover encoding and decoding of formats such as Base64, URL and hex, compression and decompression, computing hashes and checksums, symmetric encryption and decryption, character encoding conversions, parsing of common network and file formats, regular expression extraction and hundreds more, chained together in a drag and drop pipeline that shows input and output side by side.

This cloudimg image serves the official pre built CyberChef 11.2.0 release, pinned by sha256, as static files behind nginx on Ubuntu 24.04 LTS. The full toolkit answers in the browser the moment the instance boots, with an unauthenticated health endpoint for load balancer probes.

CyberChef is purely client side: every operation runs in the visitor's own browser and no data is ever sent to a server, making it a low risk way to handle sensitive material. There is no database, no login and no server side backend to manage, so the appliance is stateless and simple to operate.

The cloudimg charge covers packaging, security patching, image maintenance and 24/7 expert support. CyberChef is Crown Copyright and licensed under the permissive Apache License 2.0, and is completely free to use. See the deployment guide for the full walkthrough.
