I built an Open Graph link preview checker that shows how your URL looks in iMessage, Discord, X and the rest, including whether og:video plays

I built this Open Graph tag checker while getting og:video running on some sites I run: https://checkmyog.com Apple Messages recently added og:video support with autoplay, and Discord plays it with a tap. The tag has been around since 2010, but I expect others to follow quickly now that Messages is popularizing it, so it's worth adding now if you want rich video previews when your website links are shared. Paste a URL and it fetches the page the way the crawlers do, checks the tags agai

痛点：链接在 iMessage/Discord/X 等平台分享时，OG 标签（尤其是新近被 Apple Messages 支持自动播放的 og:video）配置不正确会导致预览不出图、不播视频，而开发者缺少一个能模拟各平台爬虫真实抓取效果的验证工具。

目标用户：独立开发者、增长营销人员和内容网站站长，特别是需要富媒体预览的站点运营者

证据：Apple Messages recently added og:video support with autoplay, and Discord plays it with a tap. The tag has been around since 2010, but I expect others to follow quickly now that Messages is popularizing it, so it's worth adding now if you want rich video previews when your website links are shared.

变现：免费单次检查作为入口，付费订阅提供每日批量 URL 监控、标签失效/被平台改规则告警、CI 集成、更高 API 配额，以及面向 AI coding agent 的可调用接口（MCP/JSON API）

MVP：2 周内：粘贴 URL → 服务端以各平台 UA 抓取 → 校验 og:* / twitter:* 标签 → 渲染 iMessage/Discord/X/Slack/LinkedIn 4–6 种预览卡片 → 生成可分享的检查报告页；先不做监控，用免登录 + 分享传播拉流量

竞品：opengraph.xyz、metatags.io、HeyMeta、SharePreview、linkpreview.net

摘要：作者用业余时间做了一个 Open Graph 预览检查工具 checkmyog.com，可模拟各平台爬虫抓取并校验标签，还能探测 og:video/图片文件是否真实可播，并附带 JSON/Markdown API 和 llms.txt 供 coding agent 自检。项目完全免费、MIT 开源，帖中未出现任何付费意愿或收入数据，需求侧主要靠作者对 Apple Messages 新增 og:video 自动播放会带动其他平台跟进的判断。同类免费工具（opengraph.xyz、metatags.io 等）已较多，纯检查工具难收费，机会更可能在批量监控告警与 CI/agent 集成方向。
