About DevDash - Toolkit
DevDash - Toolkit brings 23 everyday calculators, converters and developer utilities together in one clean, ad-supported workspace that is free for everyone.
Our mission
Simple tasks such as counting business days, converting acres to hectares or prettifying a JSON payload should not require an account, a download or a page full of pop-ups. We build focused tools that load quickly and give clear, correct answers.
Accuracy and transparency
Every tool page explains the formulas and standards it relies on, such as ISO 8601 week numbering, the 1959 international yard and pound, or the haversine great-circle formula, so you can verify the working yourself.
Privacy by design
Calculations, formatting and data generation run locally in your browser. Only a few features, such as live exchange rates and weather, request public data from third-party APIs, and they never receive the content you type.
