What It Is

PureFaas is a developer tool/platform concept built around Functions as a Service, with the page title “Pure Functions as a Service.” It aims to enhance security beyond the container isolation commonly used in FaaS: instead of allowing function containers that run custom code to hold API Keys, secrets are placed in a separate gateway container, while the function containers themselves have internet access removed.

Core Capabilities and Technical Approach

Based on the captured page content, the core idea of PureFaas is not general-purpose serverless function computing, but a “secure function invocation boundary.” Traditional FaaS already isolates different functions through containers; PureFaas goes a step further by requiring functions to send and receive requests only through a gateway container according to defined rules. This design aligns with the principles of least privilege, secret isolation, and outbound access control, making it relevant for services that handle sensitive API keys and frequently call third-party APIs.

Supported Languages, Deployment, and Ecosystem

The page does not disclose which programming languages or frameworks are supported, nor does it state whether common runtimes such as Node.js, Python, or Go are available. There is also no information on whether it is open source, whether it can be self-hosted, or whether it provides a CLI, API, SDK, CI/CD integration, or cloud provider integrations. At present, it only offers Twitter and LinkedIn follow links, and the documentation remains at the level of a product concept introduction.

Pricing and Availability

The website clearly shows “Coming soon,” indicating that the product is not officially available yet. Its pricing model, free tier, enterprise plan, and payment methods have not been disclosed. As a result, its real-world cost cannot currently be assessed; it can only be considered a pre-release or concept-stage product.

Pros, Cons, and Who It’s For

Its main strength is a clear security objective: isolating API Keys, restricting function network access, and controlling request paths through gateway rules. The drawbacks are also obvious: there is no trial product, documentation, deployment method, language support information, performance data, or case studies. It is best suited for backend teams, platform engineering teams, and security architects interested in function security models to keep an eye on, rather than as a production-ready solution to deploy immediately.

Access from China and Alternatives

The captured content does not provide any information about access from China, payment, or compliance, so availability from China should be considered unknown. If ready-made alternatives are needed, options include AWS Lambda, Google Cloud Functions, Azure Functions, Cloudflare Workers, or self-hosted options such as OpenFaaS and Knative.
