About Formattly

Mission

Everyday coding tasks often need a quick formatter, converter, or ID generator. Many online tools send what you paste to a backend. Formattly’s mission is the opposite: useful tools that stay on your device, load fast, and stay free to use.

We focus on practical developer workflows — debugging APIs, shipping safer headers, converting key formats, and generating modern IDs — with clear explanations so you know what each tool does and when it helps.

How tools work

Each page is static HTML, CSS, and JavaScript. When you paste data or click Generate / Convert, the browser runs the logic locally (including Web Crypto where cryptographic randomness or key import/export is required). There is no Formattly API that receives your tool input.

Tools are built one at a time around a real task: beautify JSON, emit UUID v7 / ULID / NanoID, parse HAR into cURL, turn .env into JSON, convert PEM ↔ JWK, or assemble a Content-Security-Policy string with server snippets. We keep dependencies minimal so pages stay light and understandable.

Who it’s for: developers, SREs, and technical marketers who want a fast, private helper without creating an account. See the full list on the homepage.

Privacy & ads

Your pasted tool content is not uploaded to Formattly. Processing happens in the page you already loaded. The site itself is hosted on Cloudflare Pages, which serves files and may see normal request metadata (IP, user agent, etc.) like any static host.

Formattly is free. We may show Google AdSense ads to support hosting and continued development. Ad partners can use cookies or similar technologies; consent and personalization options depend on your region and Google’s settings. We do not sell the text you paste into tools — that text is not sent to us in the first place. Full details: Privacy Policy.
