CyberChef

CyberChef

Browser-based tool for decoding, encoding, encryption, and data analysis using a drag-and-drop “recipe” workflow for security, DFIR, and engineering tasks.

CyberChef is a web-based data transformation and analysis tool that lets you build repeatable workflows (“recipes”) to decode, encode, decrypt/encrypt, parse, and extract information from many data formats. It’s widely used in security operations, incident response, and engineering to quickly triage unknown data and automate common transformations.

Key Features

  • Drag-and-drop recipe builder with hundreds of operations (e.g., encoding/decoding, cryptography, compression, parsing, data carving)
  • Runs fully in the browser for many operations, with optional server deployment for centralized access
  • Supports a wide range of formats and inputs (text, files, binary/hex, Base64, JWT, timestamps, URLs, certificates, etc.)
  • Recipe export/import and sharable workflows for repeatable investigations and team collaboration
  • Built-in search/filtering of operations and step-by-step inspection of intermediate outputs
  • Extensible operation set (custom operations possible via code contributions)

Use Cases

  • SOC/DFIR triage: quickly decode suspicious strings, beacons, scripts, or artifacts
  • Malware/forensics analysis: unpack/transform data (e.g., Base64/hex/gzip/XOR) and extract indicators
  • Engineering/IT tasks: convert formats, generate hashes, parse logs, and validate encodings

CyberChef provides a practical “one tool” workspace for data transformations, reducing the need to stitch together many small utilities. Its recipe approach makes investigations more consistent and easier to reproduce and share.

OmniTools

OmniTools

A self-hosted, browser-based collection of utilities for encoding/decoding, text and data conversion, and other common developer-friendly tools in one place.

OmniTools is a self-hosted web application that groups a wide range of small utilities into a single, searchable toolbox. It is designed for quick, offline-friendly use in the browser, covering common developer and “daily work” tasks like encoding/decoding, formatting, and data conversion.

Key Features

  • Collection of browser-based utilities consolidated into one web UI
  • Encoding/decoding helpers (e.g., common web-safe transforms)
  • Text/data transformation and formatting tools aimed at developer workflows
  • Simple navigation and quick access to tools from a single landing page
  • Runs as a single deployable web app (commonly via container)

Use Cases

  • Quickly format/transform text, JSON-like payloads, or snippets while debugging
  • Decode/encode values (URLs/Base64-like) when troubleshooting integrations
  • Provide an internal “toolbox” page for teams to avoid using random online tools

Limitations and Considerations

  • Feature set depends on the included tools; it is not a full IDE or automation platform
  • Some tools may overlap with specialized, dedicated utilities that offer deeper options

OmniTools is useful when you want a private, always-available set of small utilities in one place. It fits well as a lightweight internal service for engineers and technical teams who frequently need quick conversions and encoders without relying on third-party web tools.
