Frequently Asked Questions
Yes. DevBuddy is completely free with no subscriptions, no Pro tier, and no feature gating. Every one of the 43 tools is available to all users at no cost, now and in the future.
The Code Formatter supports JSON, SQL, HTML, CSS, XML, JavaScript, Java, and C#. Each language includes formatting, minification, validation, and a parsed tree view where applicable.
No. All tools process data locally on your machine. The only exception is tools that are inherently network-based (HTTP Request Tool, DNS Lookup, IP Checker) which connect to the targets you specify — no data is sent to our servers.
Notes and tasks are saved locally as JSON files in your Windows AppData folder (%APPDATA%\DevBuddy). Favourites are also persisted there. Nothing leaves your device.
DevBuddy is built on .NET 10.0. The installer will automatically download and install the required .NET runtime if it is not already present on your system.
