Explore our free D&D 5e tools and calculators — roll skill checks, calculate attack and saving throws, manage proficiency bonuses, track initiative, and roll dice instantly.
Each tool is designed to mirror the actual D&D 5e rules: advantage and disadvantage are handled correctly, modifiers are transparent, and results stay visible so you can focus on the game instead of the math.
Start with skill checks, then move to saving throws and attacks — all tools are instant and mobile-friendly.

Use the Attack Roll Calculator to determine hit or miss. If the attack hits — especially on a natural 20 — switch to the Critical Hit Calculator to roll damage.
These tools follow the core D&D 5e rules for advantage/disadvantage, modifiers, proficiency, and critical hits. Some edge cases vary by table and DM rulings, so the calculators focus on standard, transparent math.
On attack rolls, a natural 20 is a critical hit by the core rules. On ability checks and saving throws, success is based on your total vs the DC (many tables add house rules).
Absolutely. Many DMs use these tools to roll monster attacks, saving throws, and passive checks without revealing modifiers.
Some tools store recent rolls locally in your browser for convenience. Nothing is uploaded or shared.
They are optimized for D&D 5e, but many tools (dice roller, random number generator) work for other tabletop RPGs as well.
