How Formalint Works
Formalint is a static developer tools site. The current tools run with client-side JavaScript in the browser, which means formatting, validation and parsing happen on the device for normal tool usage.
Local Processing
When you paste JSON, XML, YAML, SQL, Python, regex test text or other snippets into a Formalint tool, the page processes that text in the browser. Formalint does not provide account login, cloud storage, upload queues or server-side sync for pasted tool input in this release.
What Still Loads Externally
The site uses Google Analytics and Google AdSense scripts for measurement and monetization. These services may receive standard page and browser signals according to their own policies and the consent choices available from the footer. Tool input is not intentionally sent to those services by Formalint tool code.
Safe Input Rules
Even local-first tools should be used carefully. Do not paste production passwords, private keys, live access tokens, customer personal data or unreleased business documents into any web tool. Use sanitized samples whenever possible.
Open Web Structure
Formalint is served as simple HTML, CSS and JavaScript through GitHub Pages. This keeps pages fast, inspectable and easy to navigate. Each tool page links to related guides so users can understand the limits of formatting and validation before relying on output.
