Generates random integers or decimals within a user-defined min-max range with optional repetition filtering. Uses the browser random number generator — fine for games, raffles, and sampling, not for security secrets. Everything runs locally in your browser — nothing is uploaded.
Generate random dates within a configurable range with optional format selection including ISO, US, EU, and full-date styles. Everything runs locally in your browser — nothing is uploaded.
Randomly pick one or more items from a list with optional repeat control. Perfect for giveaways, raffles, and random selection. Everything runs locally in your browser — nothing is uploaded.
Generate random times in 12-hour or 24-hour format with optional seconds and configurable time range. Everything runs locally in your browser — nothing is uploaded.
Generate random browser user-agent strings from a curated list covering Chrome, Firefox, Safari, Edge, and mobile browsers. No signup or account required.
Generates UUID v4 random identifiers in standard 36-character string format with an optional compact hex mode (no dashes). Everything runs locally in your browser — nothing is uploaded.
Set min 1, max = number of entries, enable no-repeat filtering, generate once per prize. Screen-record the draw if the audience needs proof — the tool itself keeps no audit trail.
No — it uses Math.random(), fine for games, raffles, sampling, and testing. For passwords, tokens, or anything adversarial, use the Password Generator (Web Crypto) instead.
Generated values are tracked per session and skipped on collision — guaranteed unique draws within the range. Exhausting the range (e.g., 5 unique numbers from 1–5) stops cleanly instead of looping.
Both: integers for dice, draws, and IDs; decimals for simulations and testing. Decimal precision is configurable to avoid floating-point artifacts like 0.30000000004.
No. Generation runs entirely in your browser. Nothing leaves your device.
Random String Generator
Generate cryptographically secure random strings with customizable length, count, and character sets (uppercase, lowercase, digits, symbols).
Sequence Generator
Generate number sequences in arithmetic, geometric, or custom progression. Configure start value, difference/ratio, and count. Everything runs locally in your browser — nothing is uploaded.
