Why We Built Kloubot

Every developer has a collection of bookmarked utility sites — one for JSON formatting, another for Base64, a third for regex testing. Most of them are bloated with ads, trackers, and dark patterns. We got tired of it.

Kloubot started as a personal toolkit: fast, clean developer utilities that work entirely in the browser. No sign-up walls for basic tools. No tracking your input data. No waiting for page loads stuffed with third-party scripts.

What began as a handful of formatters has grown into a platform of 28 tools spanning encoding, security, networking, data generation, and more — all built with Elixir and Phoenix LiveView for real-time interactivity without the JavaScript bloat.

What You Can Do

Kloubot covers the utilities developers reach for daily:

Encoding & Formatting — JSON Formatter, Base64 Encoder, URL Encoder, SQL Formatter
Security & Auth — JWT Decoder, Hash Generator, Password Generator
Networking & DNS — DNS Lookup, SPF Analyzer, Domain Checker
Data & Testing — Mock Data Generator, API Request Builder, Webhook Tester, CSV/JSON Converter
Regex & Patterns — Regex Tester, Regex Pattern Library, Cron Builder
Generators — UUID Generator, QR Code Generator, Lorem Ipsum, JSON Schema Generator

13 tools are completely free with no limits. Pro tools are available for developers who need advanced capabilities like DNS analysis, API testing, and mock data generation.

How It's Built

Kloubot is built with Elixir and Phoenix LiveView, which means most tools are fully interactive without writing client-side JavaScript. Input processing happens in real-time over WebSockets — type in a JSON blob and it formats instantly.

For privacy-sensitive tools like the JSON Formatter and Base64 Encoder, all processing happens client-side in your browser. Your data never touches our servers. For tools that require server interaction (DNS lookups, domain checks, API requests), we process the request and discard it immediately — nothing is logged or stored.

Privacy First

We don't sell data. We don't track what you paste into our tools. We don't require an account to use free tools. Most tools run entirely in your browser — your input never leaves your machine.
