Our journey started out of pure developer frustration. We were tired of navigating ad-choked websites, cookie banners, and paywalls just to format a block of JSON or decode a JWT. We envisioned a fast, unified, and beautifully designed developer workbench.
We spent months architecting a sandbox where tools execute 100% locally in the client browser. No inputs are sent to remote servers, offering total security for private API keys, proprietary payloads, and user credentials.
With contributions from developers globally, we scaled the lineup to cover formatting, cryptography, image compression, PDF operations, social media layout formatting, and barcode generation.
All calculations, conversions, and generations happen inside your local V8 JavaScript engine. Say goodbye to loading spinners, latency, and slow server responses.
We do not collect your code, keys, files, or parameters. By processing everything locally, we make compliance with GDPR, HIPAA, and corporate security guidelines trivial.
Seamlessly flow outputs from one tool directly into another. Copy outputs automatically or link operations together without manually copying pasting between tabs.
Focus is key. We do not disrupt your development flow with blinking ads, popups, or marketing interruptions. Just clean layouts and pure productivity.
We believe developer tools should be accessible. Karuvigal is fully translated into English, Italian, German, Spanish, French, Portuguese, Hindi, and Tamil.
Designed with a premium dark theme and smooth glassmorphism. Beautiful animations make working with raw logs, syntax highlighting, and grids a premium experience.
“Hi, I'm the developer behind Karuvigal. Like you, I was tired of juggling dozens of browser tabs for simple conversions and formatting. Every tool was on a different site, filled with trackers and ad blocks, or locked behind an account sign-up. I built Karuvigal to serve as the ultimate, clean, zero-friction developer companion. What started as a local scratch folder has grown into a fast and secure platform used by developers worldwide. I promise it will remain free, private, and open for the community forever.”
