Tooly is a free collection of 40 browser-based tools for developers, designers and creators, built by Fersoft Technologies, LLC. Each tool opens instantly, with no account and nothing to install.
Yes. Every tool is free, with no account, subscription or usage limit.
Most tools run entirely in your browser, so what you paste or open never leaves your device. The DNS, SSL and Domain checkers and the iFrame Tester have to query public services to do their job, and Huddle uses a signaling server to connect calls. None of them store what you enter.
40 tools across 7 categories: business (Invoice Generator, UTM Builder); developer (JSON Viewer, Base64 Encoder / Decoder, iFrame Tester, HTML Viewer, Regex Tester, Markdown Editor, Timestamp Converter, Text Diff, Word Counter, Notepad, To-Do List, UUID Generator, URL Encoder/Decoder, Case Converter, JSON, CSV & YAML Converter, Cron Expression Explainer); media (Image Editor, Huddle); documents (PDF Editor); security (JWT Decoder, Hash Generator, Password Generator, 2FA Authenticator); design (Color Palette Generator, QR Code Generator, CSS Gradient Generator, SVG Viewer, QR Code Scanner, Favicon Generator); network (DNS Checker, SSL Checker, Domain Checker, Internet Speed Test, Website Speed Test, SEO Analyzer, What Is My IP, SPF, DKIM & DMARC Checker, Redirect & HTTP Header Checker).
No. Tooly runs in any modern browser on desktop or mobile. You can also install it as an app from the browser menu to open the tools offline.
Tooly is built and maintained by Fersoft Technologies, LLC.
