About
Fast tools. Lightweight games. Local-first design.
Online Dev Tools is an independent web studio focused on building fast, lightweight browser tools and small interactive games.
This site is designed to provide:
- Quick functional utilities that solve small tasks efficiently.
- Browser-based developer and security tools (JSON formatting, JWT decoding, CSP analysis, hash generation, UUID generation, and log inspection).
- Lightweight browser-native games that load instantly.
- A clean, minimal environment without social feeds or account systems. Design Principles:
Speed. Pages are intentionally lightweight and optimized for fast load times.
Privacy. No accounts required. No forced sign-in. No unnecessary data collection.
Local-first interaction. Tool inputs and outputs are designed to stay in your browser whenever technically possible. Some tools or games may use local storage to remember preferences or progress.
Focused utility. Each page aims to solve a specific problem cleanly, without turning into a bloated dashboard.
Sustainable support. Advertising may be displayed to support hosting and development. Core functionality is not restricted by ads. Online Dev Tools is built for developers, IT professionals, security engineers, and technically curious users who value speed and minimal friction.
Online Dev Tools is not a social platform, subscription service, or marketplace. It is a focused, evolving web studio built for practical use and lightweight interaction.
