About
Built for IT workdays, not busywork
DailyTool is a free toolkit of browser-native utilities for developers, SREs, QA, and support engineers. Format JSON, decode JWTs, calculate subnets, generate UUIDs, explain cron—and keep moving without installing another app.
What makes DailyTool different
- Private by design: tools run in your browser; inputs are not uploaded to our servers.
- Zero install: open a page and work—no extensions required.
- IT-focused catalog: formatters, encoders, generators, converters, and ops helpers in one place.
- Sample data everywhere: every tool includes examples so you can learn by doing.
Who it’s for
Engineers debugging APIs, support teams reading logs, SREs checking CIDR ranges, and anyone who needs a trustworthy utility in the middle of an incident or a sprint. DailyTool aims to replace a messy bookmark folder of one-off sites.
Featured products
Beyond the in-browser toolkit, DailyTool also offers focused apps like QuickChecklist and QuickPerformaCalc.
