Uptimepage
Uptime monitoring, status pages and on-call in one open-source tool
Uptimepage watches your websites and APIs, pages the right person when one breaks, and tells your customers on a status page. It does the job that usually takes a monitoring tool, a status page service and an on-call app. Checks run from up to 13 regions around the world. A monitor can wait until most regions agree it is down before opening an incident, so one bad network route does not page anyone at 3am. There are nine kinds of check: HTTP, TCP, DNS, ping, heartbeats for cron jobs, TLS certificate and domain expiry, a real browser that signs in through your login page, and manual monitors you set by hand. Alerts reach Slack, Discord, Teams, Telegram, email, SMS, PagerDuty, ntfy, Pushover, WhatsApp or any webhook. On the Team plan, on-call rotations and escalation policies decide who gets paged, and who is next if nobody acknowledges. Incidents and planned maintenance show up on a hosted status page with your logo, and customers can subscribe to updates instead of emailing you to ask. Each plan has one flat price with seats included. The free plan has 20 monitors and a status page, no card needed. Pro is $9 a month and Team is $19. The code is open source under AGPL-3.0, so you can also self-host it with docker compose. There is a REST API, a Terraform provider and an MCP server.

IsoCity
Buy a plot in a shared 60x60 festival market city
IsoCity is a browser-based city where visitors claim a plot of land in a 60x60 festival market. Walkways between plots stay public, so the city remains open to everyone who visits. Plot prices depend on location. Stagefront, Fairway, Midway and Outskirts are the zones that set what a plot costs, so buyers can choose between a prime spot near the stage and a cheaper plot further out. The site is aimed at people who want to own a small piece of a shared, community-built market. The homepage text is limited, so details about the build, the economy and how plots are managed are not described here.
