frp

frp is an open-source fast reverse proxy that exposes services running behind a NAT or firewall to the public internet. Both the server (frps) and the client (frpc) include built-in HTTP admin APIs that operators can use to inspect runtime status, manage proxies and visitors, hot-reload configuration, and scrape Prometheus metrics.

frp publishes 9 APIs on the APIs.io network, including Clients API, Configuration API, Health API, and 6 more. Tagged areas include NAT Traversal, Reverse Proxy, Tunneling, and Open Source.

frp’s developer surface includes authentication, documentation, getting-started guide, release notes, and 6 more developer resources.

Where this information came from

This is an independent, third-party profile of frp, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
