RANDOM.ORG

What RANDOM.ORG does

RANDOM.ORG, operated by Randomness and Integrity Services Limited (Ireland, company no. 489434) and founded in 1998 by Prof. Mads Haahr of Trinity College Dublin, generates true random numbers from atmospheric noise and delivers them as free web tools, paid professional services, and a JSON-RPC API. The core platform is differentiated from pseudo-random number generators by its physical entropy source, supplemented by SHA-512 digitally signed API responses for non-repudiation, unforgeable verification codes for video-streamer giveaways, historical/pregenerated randomness for reproducible sequences, and a ticket system for sequential lottery or gambling operations. Free offerings include the Integer Generator, List Randomizer, Password Generator, Lottery Quick Pick (covering over 280 lotteries), dice/coin/card games, audio noise files, and embeddable widgets; paid offerings include the Third-Party Draw Service for professional lottery and sweepstakes operators and the Multi-Round Giveaway Service (launched 2022) priced at $1–$300 per month depending on volume and tier. The company is bootstrapped, privately held, GDPR-compliant, and operates with a 1–10 person team from Dublin, distributing globally through a self-serve, product-led, and API-first model with no paid advertising.

Direct peers

• ShortStack: ShortStack is a contest and giveaway builder used by marketers to run campaigns with random winner selection. Directly comparable as a giveaway/drawing platform serving the same sweepstakes organizer segment as RANDOM.ORG's draw service.
• Woobox: Woobox provides sweepstakes, contests, and promotional drawing tools for brands and agencies. Comparable as a sweepstakes/drawing platform that competes with RANDOM.ORG's Third-Party Draw Service, particularly for marketing-driven drawings.
• Rafflecopter: Rafflecopter is a web-based giveaway and contest platform used by bloggers and brands. Directly competes with RANDOM.ORG's Third-Party Draw Service and giveaway tools in the online drawing and sweepstakes organizer segment.
• Gleam: Gleam is a leading giveaway and contest platform for creators and marketers, supporting viral giveaways across websites and social channels. Directly competes with RANDOM.ORG's Multi-Round Giveaway Service for the same video streamer and creator audience, though Gleam focuses on growth/marketing mechanics rather than cryptographic verification.

Emerging players

• Quantum Dice: Quantum Dice is an Oxford spin-out developing chip-based quantum random number generators for security and gaming applications. Comparable as a true randomness provider, particularly targeting gambling and lottery use cases that overlap with RANDOM.ORG's Signed API and Third-Party Draw Service.
• Chainlink VRF: Chainlink VRF is a verifiable random function oracle providing cryptographically provable randomness to smart contracts. Comparable as a cryptographically verifiable randomness service for gambling, NFT, and lottery use cases, though targeting blockchain developers rather than traditional web/enterprise.
• QuintessenceLabs: QuintessenceLabs provides quantum random number generation and quantum-safe security solutions, targeting government and enterprise customers. Overlaps with RANDOM.ORG's cryptographic randomness use cases but positioned at higher-end enterprise with hardware-delivered entropy.
• API3 QRNG: API3's QRNG is a blockchain-native oracle service that delivers quantum random numbers on-chain via Airnode. Comparable as a randomness-as-a-service offering with cryptographic verifiability, targeting Web3 gambling and NFT use cases that overlap with RANDOM.ORG's Flexible Gambling License.

Broad incumbents

• ID Quantique: ID Quantique is the leading commercial provider of quantum random number generators (QRNG), offering hardware-based true randomness chips and servers. Comparable as a competing source of true (non-pseudo) randomness, though primarily hardware-oriented versus RANDOM.ORG's atmospheric noise / software service.
• Smartplay International: Smartplay is an established manufacturer of lottery draw equipment, including physical ball drawers, RNG systems, and audit services for government and licensed lottery operators. Comparable as a lottery draw infrastructure provider, though Smartplay focuses on physical/hardware systems and certified RNG hardware rather than atmospheric noise software.
