Featured tool

SQL Compare

Two versions of a query look different. Is it just formatting, or did the meaning change? SQL Compare puts both side by side and labels every difference, so you review the changes that matter first.

  • Labels every difference as formatting, structural or potentially semantic
  • Real PostgreSQL and MySQL / MariaDB parsers, plus a Generic mode
  • Runs entirely in your browser: no uploads, no analytics, works offline
  • Export the difference report as Markdown, HTML or JSON

SQL Compare comparing two versions of a PostgreSQL query side by side. The summary reports 4 semantic, 1 structural and 5 formatting differences, and the Differences panel lists an added u.email column and a JOIN changed from INNER to LEFT.

Scripting zone

Scripts you can read before you run

Small, focused scripts for the chores that come up again and again: cleaning up a repo, checking a database, wiring a quick automation.

No scripts are published yet. Each one will get its own page and will only go up once it has been tested.

Focus areas

  • Shell / Bash
  • JavaScript / Node.js
  • Python
  • Database / SQL
  • Automation & DevOps

Hacker zone / Labs

A lab for curious experiments

The Lab is where ideas get taken apart to see how they work. Nothing is published there yet; this is what it is for.

  1. Interactive demos

    Small, hands-on explanations of how something works under the hood.

  2. Performance experiments

    Measured comparisons, with the method and numbers published.

  3. Code visualizers

    Ways to see structure, data flow or diffs instead of reading them.

  4. Workflow prototypes

    Rough ideas for developer tooling, shared before they become tools.

  5. Defensive security

    Educational material and testing utilities for systems you own.

policy “Hacker” here means curiosity and building things. Security content on AllOfCode is educational and defensive. It is not for getting into systems you aren't authorised to access.

Why AllOfCode

Small tools, held to a high bar

  • Built around real workflows

    Each tool starts from a task developers repeat, such as reviewing SQL changes before they ship.

  • Open it and start

    No accounts and no setup. A tool should be useful within the first minute.

  • Your code stays with you

    When a tool can run in your browser, it does. SQL Compare never sends your SQL to a server.

  • Limits are documented

    Tool pages say what is not supported as clearly as what is, so you know when to reach for something else.
