Base64 Encode / Decode
Instantly encode plain text to Base64 or decode Base64 strings back to readable text.
Code Formatter
Format JavaScript, TypeScript, HTML, CSS, and JSON with consistent indentation rules.
Code Audit
The Code Audit tool analyses pasted code snippets using a set of deterministic, rule-based checks to surface common quality issues, risky patterns, and maintainability concerns.
Website Audit
The Website Audit tool fetches a public URL and runs a set of deterministic checks against the page response and its HTML. In seconds it surfaces the most common technical SEO, metadata, security, and crawlability issues that affect how search engines index pages and how users experience them.

Questions & Answers

As answered by people managing DUMMY DATABASE and CodeAva.

What makes your product unique?

DUMMY DATABASE's answer

A free, all-in-one data generation platform that builds everything from simple tables to full relational databases with advanced controls, unique event sequences, ERD visualization, built-in SQL querying, and multiple export formats — no limits, no paywalls.

CodeAva's answer:

CodeAva acts as an Automated Validation Assistant (AVA) for developers. CodeAva combines website audits, code audits, and practical developer tools in one clean workflow. Instead of offering a single utility, it helps developers and technical teams validate what they are about to ship — from technical SEO and response headers to code quality, timestamps, IDs, JWTs, and debugging helpers. It is built to be fast, browser-friendly, and genuinely useful in real development and QA workflows.

Why should a person choose your product over its competitors?

DUMMY DATABASE's answer

Unlike other data generators, DUMMY DATABASE gives you full relational database creation, unique event simulations, advanced control over every field, built-in SQL querying, and generous free limits — so you can go from idea to test-ready data without restrictions, subscriptions, or hidden fees

CodeAva's answer:

CodeAva is designed for practical validation, not just isolated utilities. It gives users a mix of audits, developer tools, examples, and technical guides that help catch issues earlier and act on them faster. The product focuses on clarity, useful outputs, and developer-first workflows, with many core tools available without signup.

How would you describe the primary audience of your product?

DUMMY DATABASE's answer

Developers needing dummy databases for prototyping & testing.
Analysts and BI specialists preparing demo dashboards.
QA engineers creating data scenarios for testing.
SQL learners who want practice datasets on demand.

CodeAva's answer:

CodeAva is built for software developers, QA-minded teams, technical founders, agencies, and site owners who want to catch code, performance, SEO, and validation issues before they reach production.

What's the story behind your product?

DUMMY DATABASE's answer

Began as a project for myself to be able to have custom datasets for testing purpose I've decided that it could be useful for wider audience and finalized it as a full-stack web project

CodeAva's answer:

CodeAva stands for Automated Validation Assistant. It was created around a simple frustration: too many quality checks happen too late, across too many disconnected tools. The goal is to make validation faster, clearer, and more useful for teams that ship real code, real websites, and real products.

Which are the primary technologies used for building your product?

DUMMY DATABASE's answer

Python, Flask, HTML, CSS, Bootstrap, Redis, PostgreSQL, JavaScript

CodeAva's answer:

CodeAva is built primarily with Next.js, React, TypeScript, Tailwind CSS, and modern browser APIs, with a strong focus on fast front-end performance, clean UI, and browser-based developer tooling.
