About Flashman
Free browser-based developer tools: JSON, JWT, Base64, YAML, MATLAB/Simulink helpers, and more. Fast, private, and client-side.
Who we are
Rahul Chitturi is a software engineer and developer tools enthusiast who created Flashman to provide fast, reliable, and privacy-focused utilities for the developer community. With years of experience in web development, API integration, and DevOps workflows, the goal is to build tools that respect your time and your data.
Every tool is designed with privacy in mind—processing your data locally in the browser whenever possible, so sensitive information never leaves your device.
Why we built this
Developers and domain automation engineers need fast, trustworthy utilities without uploading sensitive payloads to unknown servers. Flashman runs transformations in your browser whenever possible and keeps the interface minimal.
What you will find
28+ tools across encoding, formatting, generation, conversion, debugging, text utilities, and MATLAB/Simulink helpers. We also publish 255 original guides on topics like JWT safety, JSON validation, cron schedules, and client-side privacy.
