About devpack

devpack.app is a growing collection of small, focused tools that remove friction from everyday web work — formatting JSON, decoding a JWT, checking redirects, generating schema markup, pasting SVGs into Webflow or compressing an image.

Principles

• Private by default. Most tools run entirely in your browser; your input never reaches our servers or any analytics or ad provider.
• No signup. Open a tool and use it.
• Fast. Lightweight pages, keyboard shortcuts (Ctrl+K to search, Ctrl+Enter to run).
• Shareable. Many tools keep their settings in the URL so you can bookmark or share them.

Server-side tools

Tools that need to fetch a website (SEO checks, link checking, DNS, SSL) run on our server. They only request publicly available pages, our crawler respects robots.txt, and results are kept in temporary memory for a few minutes — never stored in a database.

How it stays free

devpack.app is free to use. We may show a limited number of clearly marked ads from Google AdSense to cover hosting and development, and — with your permission — use Google Analytics to see which tools are useful. Ads never interrupt a tool and never see what you type into a browser-based tool. You control analytics and ad personalization under Your privacy choices. Details are in our Privacy Policy.

Independence

devpack.app is an independent project and is not affiliated with, sponsored by, or endorsed by Webflow, Inc., Figma, Inc., Google LLC or any other company whose products our tools work with.
