Postmoderno is an MCP social media scheduler for ChatGPT and Claude, and I build it. There is no compose box: you tell your agent what to post and when, and it goes out to your socials on popular platforms. Every post gets a preview first, showing how each platform will display it, and nothing is scheduled until you confirm. Threads, images and quote posts go through the same conversation, and your agent can check what went out and why something failed. One Go binary on Postgres.
Uptimepage is hosted uptime monitoring and public status pages for teams, and I build it. Checks run every 60 seconds from five regions; a failing check opens an incident and posts it to your status page. Eight check types: HTTP, TCP, ping, DNS, TLS and domain expiry, cron heartbeats, browser logins. Alerts to Slack, Telegram, PagerDuty and webhooks, with flap suppression so one bad probe never pages you. As code via REST API, Terraform or MCP. One Rust binary on Postgres and ClickHouse, AGPL.
