The short answer先说结论
Stay with UptimeRobot if这些情况继续用 UptimeRobot
- You mostly need many free monitors: UptimeRobot lists 50 on its free plan, OpenUptime Free has 3.你主要需要大量免费监控：UptimeRobot 免费版有 50 个，OpenUptime 免费版只有 3 个。
- A simple hosted service is enough, or you need ping and UDP monitors or SMS and voice alerts.一个简单的托管服务就够用，或者你需要 Ping、UDP 监控，以及短信和语音告警。
Choose OpenUptime if这些情况选 OpenUptime
- You want to own the infrastructure: the MIT core runs with Docker, or on Cloudflare with Postgres.你想自己掌控基础设施：MIT 开源核心可用 Docker 部署，或跑在 Cloudflare + Postgres 上。
- Several people manage monitors: hosted members are unlimited from Lite.多人一起管理监控：托管版从 Lite 起成员不限。
- You want PostgreSQL, MySQL and Redis checks next to HTTP, TCP, DNS and heartbeat.你想在 HTTP、TCP、DNS 与心跳之外，同时检查 PostgreSQL、MySQL 和 Redis。
If your reason for leaving UptimeRobot is “I want more free monitors,” OpenUptime hosted is unlikely to help. Its Free plan has three active monitors. The stronger reasons to consider it are owning your monitoring infrastructure, sharing access with a team, or combining endpoint and database checks. Here is how to decide without confusing monitor limits with monitoring capacity.如果你离开 UptimeRobot 是为了“获得更多免费监控”，OpenUptime 托管版大概帮不上忙：Free 只有 3 个活跃监控。更值得考虑它的理由，是自己掌控监控基础设施、团队共享管理权限，或同时监控端点和数据库。做决定之前，要先区分监控数量上限和实际检查容量。

Start with the free-plan arithmetic先算免费版的账
UptimeRobot lists 50 free monitors at five-minute intervals. Solo starts at $10 billed monthly or $9/month billed annually for 10 monitors; its 50-monitor tier lists $22 or $19. Team (100 monitors, 30-second checks) lists $41 or $35. Prices are USD as shown on October 12, 2026. Paid tiers offer faster intervals and more collaboration options. For basic personal websites, that free allowance is a compelling reason to stay. Source: UptimeRobot pricing.UptimeRobot 列出了 50 个免费监控，间隔为 5 分钟；Solo 含 10 个监控，月付 $10，年付折合 $9/月；50 个监控的档位为 $22 或 $19。Team（100 个监控、30 秒间隔）分别为 $41 和 $35。价格为 2026 年 10 月 12 日页面显示的美元价。付费套餐提供更快的检查和更多协作选项。只监控个人网站时，这个免费额度就很有吸引力。来源：UptimeRobot 定价。
OpenUptime Free can sustain its three monitors at five-minute intervals in a 30-day month: 3 × 8,640 = 25,920 checks, just under its 26,000 allowance. In a 31-day billing period the same setup needs 26,784 checks, so checks would pause for roughly the last 22 hours. That is a small starting plan, not an equivalent replacement for 50 free monitors.按 30 天计算，OpenUptime Free 可以让 3 个监控持续每 5 分钟检查：3 × 8,640 = 25,920 次，略低于 26,000 次额度；若账期为 31 天，同样的配置需要 26,784 次，账期最后约 22 小时检查会暂停。它适合小规模起步，不能等同于 50 个免费监控。
What $5 actually covers5 美元到底覆盖多少
Lite allows 50 active monitors, but its 300,000 checks only sustain six monitors checked every minute for a full 30-day month. Fifty one-minute monitors need 2,160,000 checks in a 30-day month, exactly Starter’s $19/month allowance, so a 31-day billing period or any extra region would exceed it. All OpenUptime prices here are USD, billed monthly. Our pricing page shows both limits.Lite 允许 50 个活跃监控，但 300,000 次额度只够 6 个监控连续 30 天每分钟检查。50 个监控全部每分钟检查，30 天需要 2,160,000 次，正好等于 $19/月 Starter 的额度；遇到 31 天的账期或增加检查区域就会超出。本文 OpenUptime 价格均为美元、按月订阅。价格页列出了这两种限制。
Mixed intervals can make Lite useful: two critical endpoints every minute plus twenty secondary endpoints every five minutes consume 259,200 checks over 30 days. Leave headroom for longer billing periods and additional checks. This is capacity arithmetic, not a claim that $5 buys 50 one-minute monitors.混合间隔时，Lite 仍然实用：2 个关键端点每分钟检查，加上 20 个次要端点每 5 分钟检查，30 天共消耗 259,200 次。还需要为更长的账期和额外检查留余量。这只是容量计算，并不是说 5 美元能买到 50 个一分钟监控。
Where OpenUptime is a better fit哪些场景更适合 OpenUptime
The open source core includes workspaces, projects, roles, HTTP, TCP, DNS, heartbeat, PostgreSQL, MySQL and Redis checks. Run it in Docker near private services, or on your own Cloudflare account with Postgres. A database protocol check confirms that something answers the PostgreSQL, MySQL or Redis handshake (no credentials or queries are sent). That separates a reachable port from the wrong service; it does not replace application-level health checks.开源核心包含工作区、项目、角色，以及 HTTP、TCP、DNS、心跳、PostgreSQL、MySQL 和 Redis 检查。可以用 Docker 部署在私有服务附近，也能部署到自己的 Cloudflare 账号并连接 Postgres。数据库协议检查只确认对端能回应 PostgreSQL、MySQL 或 Redis 的握手（不发送凭据，也不执行查询），可以区分“端口可达”与“服务不对”，但不能代替应用层健康检查。
Self-hosting removes product quotas, while making you responsible for compute, backups, email delivery and upgrades. SSL expiry monitoring is hosted-only, from Lite; custom status-page domains are hosted-only on Team. These are real limits of the current MIT edition. Read the open-source vs hosted table and the deployment guide before choosing it.自托管没有产品配额限制，但计算资源、备份、邮件发送和升级由你负责。SSL 到期监控仅托管版 Lite 起提供；状态页自定义域名仅托管版 Team 提供。这些是当前 MIT 版本的实际边界。选择前请先看开源版与托管版对比表和部署文档。
UptimeRobot is broader on monitor types and channels: it offers ping and UDP monitors, SMS and voice alerts, a 15-second interval on Scale and mobile apps. OpenUptime has no ICMP ping or UDP monitor type, and its alert channels are email, Slack, Telegram, webhook, PagerDuty and Lark.UptimeRobot 在监控类型和通知渠道上更全：支持 Ping、UDP 监控，短信和语音告警，Scale 套餐有 15 秒间隔，并提供移动应用。OpenUptime 目前没有 ICMP Ping 和 UDP 监控类型，告警渠道为邮件、Slack、Telegram、Webhook、PagerDuty 和飞书。
An API or MCP is not a unique differentiatorAPI 和 MCP 并非独有优势
UptimeRobot also publishes an MCP integration. Compare the specific actions your agent needs, authentication and access scope, rather than treating the existence of MCP as a reason to migrate. OpenUptime documents its own tools in the MCP reference.UptimeRobot 同样提供 MCP 集成。应该比较代理需要的具体操作、认证方式和权限范围，而不是因为有 MCP 就迁移。OpenUptime 的工具见 MCP 文档。
A migration that proves the replacement works迁移前先验证替代方案
Begin with one public HTTP check and one authenticated endpoint. Recreate expected status, keyword rules, timeout and failure threshold. Run both services through a deliberate failure and recovery, and confirm the right people receive alerts. A shorter interval alone does not guarantee faster notification: retries and failure thresholds affect detection time.先迁移一个公开 HTTP 检查和一个需要认证的端点，核对预期状态码、关键词、超时和失败阈值。让两个服务同时经历一次人为故障和恢复，确认通知到达正确的人。检查间隔更短不一定通知更快，重试和失败阈值同样影响发现时间。
For bulk creation, map records to the documented monitor import format. Common field aliases are accepted, but numeric vendor type IDs need explicit conversion, and ping or UDP monitors have no equivalent and are skipped. The whole file is refused if it would exceed your plan’s active-monitor limit, and intervals shorter than the plan’s minimum are raised to it. Only channels set to auto-enable are attached; reconnect the rest yourself. The endpoint creates monitor configuration; do not expect historical incidents or subscribers to transfer. Keep the old service until the new alerts and status page have passed your checks.批量创建时，把记录映射到文档中的监控导入格式。支持部分常见字段别名，但竞品的数字类型 ID 需要手动转换，Ping 和 UDP 监控没有对应类型，会被跳过。如果导入后超出套餐的活跃监控上限，整个文件会被拒绝；短于套餐下限的间隔会被自动提高到下限。只有设置为自动启用的告警渠道会被绑定，其余需要自己重新关联。导入接口创建监控配置，不会因此迁移历史故障或订阅者。新告警和状态页验证通过后，再停用旧服务。
