About OSRSTools
OSRSTools.net provides free, accurate calculators, guides and utilities for Old School RuneScape players. Our goal is to make complicated in-game calculations and planning easy so you can spend more time playing and less time guessing.
We aim to publish clear, reliable, and up-to-date tools and guides for OSRS. Everything on this site is free and designed to work well on desktop and mobile. We prioritize accuracy and usability — if something looks off, let us know on our Discord (link in the header or the Contact page).
We also maintain changelogs for major tool updates and try to be transparent about data sources and assumptions. Contributions from the community (bug reports, PRs, clarifications) are welcome.
Most calculators rely on community-verified formulas and public OSRS data sources (wiki, hiscores, Grand Exchange APIs). When possible we cite sources inside guides or tool descriptions.
If you want to contribute: open an issue on our GitHub, post in the Discord, or submit a PR with corrected formulas or improved copy. We review contributions regularly.
