Want these capabilities built natively into your sprint board?

Why We Built Free Agile Tools

Agile ceremonies shouldn't require cumbersome spreadsheets or expensive per-seat software just to estimate a backlog or calculate available developer hours. We built these utilities to help engineering teams plan with data, prevent burnout, and deliver with precision.

Privacy & Data Security

Every calculation runs entirely in your browser client-side. We do not store your team members' names, sprint estimates, or risk assessments on external servers. You can safely calculate sensitive project bandwidth and export records immediately.

Beyond Calculators

When your team outgrows isolated tools and wants project management, QA testing, engineering docs, and capacity planning in a unified interface, explore Klority โ€” replacing Jira, Confluence, and TestRail at an 80% lower cost.
