FunCDN 是一套可私有化部署的自建 CDN 系统。内容分发、安全防护、高可用容灾和日志分析归拢在同一套系统里，由一个主控管理边缘节点、回源中继和源站。主控和节点都部署在您自己的服务器上，配置、日志和数据由您自己掌握。 FunCDN is a self-hosted CDN system you can deploy privately. Content delivery, security, high-availability failover and log analytics come together in one system, with a single control plane managing edge nodes, origin relays and origins. The control plane and the nodes run on your own servers, and you keep the configuration, the logs and the data.
站点接入、缓存与回源、安全防护、证书、日志分析、节点运维和开发者接口，都从主控配置。首页只列要点，逐项说明在产品能力页。Site onboarding, caching and origin pull, security, certificates, log analytics, node operations and developer APIs are all configured from the control plane. The homepage lists the highlights; the capabilities page covers each one in detail.
域名接入后，流量由源站池负载均衡，并配主动健康检查；缓存分内存和磁盘两级，一键刷新下发到节点。Once a domain is onboarded, traffic is load-balanced across the origin pool, with active health checks behind it. The cache has two tiers, memory and disk, and a one-click purge is pushed out to the nodes.
WAF、IP 黑白名单、访问限速、CC 防护和 JS Challenge，策略统一下发到边缘，每个站点可以单独组合。WAF, IP allow and deny lists, rate limiting, CC defense and JS Challenge. Policies are pushed to the edge from one place, and each site can combine them differently.
证书可以手动上传，也可以走 ACME 自动签发和续期。另外支持 CNAME Target，以及多家 DNS 服务商的授权接入。Upload certificates manually, or let ACME issue and renew them automatically. There is also CNAME target support and credentials for multiple DNS providers.
访问、缓存、回源和高可用日志都有记录，另有探测和审计。做日志分析时，可以选择接入外置 ClickHouse。Logs cover access, cache, origin pull and high availability, with probing and audit alongside them. Log analytics can optionally connect to an external ClickHouse.
cdn-agent 采用签名升级，配置实时下发，节点侧用本地缓存做容错。健康心跳、备份恢复和操作审计也一并提供。cdn-agent upgrades are signed, config is pushed live, and nodes fall back to their locally cached copy. Heartbeats, backup and restore, and an operation audit trail are provided as well.
REST API 配 API Token，接口按 OpenAPI 3.0 规范描述。边缘规则、脚本模板和用户 Edge KV 也都支持。A REST API with API tokens, described by an OpenAPI 3.0 spec. Edge rules, script templates and user Edge KV are supported as well.
主控负责编排和配置下发，业务请求由边缘节点自己承载。节点与主控暂时断连时，仍按本地缓存的配置继续服务；运行日志则单独汇入日志分析数据面。The control plane handles orchestration and config push, while edge nodes carry the request traffic themselves. If a node loses its connection to the control plane for a while, it keeps serving from the config it has cached locally. Operational logs take a separate path into the log analytics data plane.
这三个是比较典型的场景，用的都是现有产品能力的组合。其余场景和对应的能力列在应用场景页。These three are representative, and each one is a combination of capabilities the product already has. The rest, along with the capabilities behind them, are on the use cases page.
内容分发跑在自己的服务器和带宽上。主控和节点都在自有网络里，配置和日志不用出内网。Content delivery runs on your own servers and bandwidth. The control plane and the nodes both sit inside your network, so configuration and logs never have to leave it.
源站池做负载均衡，同时用主动健康检查发现故障，再自动切到可用的源站。也可以部署回源中继，当作备用的回源链路。The origin pool load-balances traffic and uses active health checks to detect failures, then switches automatically to a healthy origin. An origin relay can also be deployed as a backup path to the origin.
关键站点可以挂高可用规则。主地址请求失败后，浏览器按顺序探测预设的备用地址，跳到第一个能通的；备用地址全部不可达，才显示离线页面。仅增强版和定制版可用。Critical sites can have HA rules attached. After a request to the primary fails, the browser probes the preset backup addresses in order and redirects to the first reachable one. The offline page appears only if none of the backups are reachable. Available in the Enhanced and Custom editions only.
全功能版已经开放全部 CDN 核心功能，价格按节点数和 Zone（根域名）配额分档。增强版在同样的核心之上加了高级功能和专家服务，定制版再加上定制研发与专项交付。The Full edition already includes every CDN core capability, priced by node count and Zone (root domain) quota tier. Enhanced keeps that same core and adds advanced capabilities and expert services. Custom goes further, with project-specific development and delivery.
10 个节点、100 个 Zone 起，共五档配额Starts at 10 nodes and 100 Zones, across five quota tiers
私有化运营一套 CDN 需要的核心能力，这一档都有。This edition has the core capabilities needed to run a private CDN.
在所选基础月费之上，叠加高级功能与专家服务Added to whichever base monthly fee you choose, for advanced capabilities and expert services
全功能版的全部内容，再加高级功能和专家服务。Everything the Full edition has, plus advanced capabilities and expert services.
定制研发与定价都按项目范围评估Development scope and pricing are both assessed per project
面向更大规模或特殊部署需求，按项目范围做定制研发。For larger scale or special deployment needs, with development scoped to the project.
价格看两件事：授权节点数，和授权站点数。授权站点按根域名 Zone 算，同一个 Zone 下的子域名不额外占配额。增强版是所选全功能版基础月费再加 ¥999/月，定制版按需求范围评估。五档完整价格和计算器在授权定价页，版本之间的差异见 高级功能对比。 Two numbers set the price: how many nodes you license, and how many sites. Licensed sites are counted per root-domain Zone, and subdomains under the same Zone use no extra quota. Enhanced is the Full base monthly fee you choose plus ¥999/mo, and Custom is priced against the scope of the project. All five price tiers and a calculator are on the pricing page, and the advanced comparison shows how the editions differ.
下面是首页摘选的几行，完整的逐项矩阵在功能对比页。三个版本的核心功能状态一样，差别集中在高级功能、专家服务和定制研发上。These rows are a homepage selection; the full item-by-item matrix is on the feature comparison page. Core capabilities read the same across all three editions, and the differences sit in the advanced features, the expert services and the custom development.

这里列出三个常见问题。部署、授权、配额、高可用、日志分析和旧版本兼容的完整说明都在常见问题页。Three common questions. The full answers on deployment, licensing, quota, high availability, log analytics and legacy compatibility are on the FAQ page.
按节点数和授权站点数（以根域名 Zone 计）透明计费。选哪一档看实际部署规模，选哪个版本看您需要哪些高级功能与服务。Transparent pricing, based on licensed node count and licensed sites counted per root-domain Zone. The tier follows your deployment size; the edition follows which advanced capabilities and services you need.
