Pure Random is a certified hardware random number generation service operated by Jammy LTD. It is built on AWS CloudHSM and claims to use FIPS 140-2 Level 3 validated hardware. Rather than being a regular Math.random() or pseudorandom algorithm service, it emphasizes random numbers derived from the physical entropy source of a hardware security module, and provides an Audit ID for each generated result to support third-party verification.
In terms of functionality, Pure Random can generate random numbers based on minimum value, maximum value, quantity, and uniqueness requirements. Generation records include information such as timestamp, range parameters, quantity, and entropy source. Its key selling point is an immutable audit trail: database triggers prevent audit records from being updated or deleted, while pgaudit and AWS CloudTrail are used to log access and infrastructure changes. It also uses rejection sampling to avoid modulo bias, making it suitable for scenarios that require a uniform distribution.
The disclosed technology stack includes AWS CloudHSM, PostgreSQL, pgaudit, and AWS CloudTrail. Its infrastructure is hosted in the AWS eu-west-2 London region, with data residency in the UK. On the certification side, the site mentions AWS CloudHSM FIPS 140-2 Level 3, GLI-19 certification for the system, and passing NIST SP 800-22 tests. From a developer perspective, the page states that the free public API supports up to 100 numbers per request and a maximum range of 10 million; higher limits, batch generation, commercial API access, and raw entropy APIs require an enterprise plan. However, we did not find SDKs, code examples, authentication details, or complete API documentation.
The public generator is free for individuals and light usage. Commercial, high-volume, or API use requires contacting the company for a paid plan, which includes higher limits, dedicated support, and an SLA, but pricing is not disclosed. It is better suited for raffles, competitions, gambling, lottery systems, research sampling, and cryptographic applications that require a hardware entropy source, rather than ordinary websites or scripts that only need a local random function.
Its strengths are trusted randomness, public verifiability, immutable audit records, and a relatively complete compliance narrative. The drawbacks are opaque pricing, limited developer documentation, no stated self-hosting option, and limited information about ecosystem integrations. The source material does not mention access from China. Given that it is hosted in the AWS London region, connectivity and latency would need to be tested in practice; payment methods are also not disclosed. If you only need basic random numbers, Random.org, Cloudflare randomness beacon, or a languageβs built-in CSPRNG may be alternatives. If strong compliance is required, building your own solution on AWS CloudHSM may be worth evaluating.
