What is OpenPanel?

OpenPanel tags three more note-free builds in one evening, reaching 3.16.4.

OpenPanel tagged 3.16.2, 3.16.3 and 3.16.4 within about 80 minutes on October 27, after 3.16.1 the day before. Every entry is a build of main for supporters, installed with openpanel upgrade --supporter, and none carries release notes; public releases come from a separate self-hosting tag.

What is updown.io?

updown.io adds closed port monitoring and a detailed check metrics page with multi-year uptime heatmaps.

updown.io has been steadily expanding beyond simple HTTP uptime monitoring: pulse monitoring for cron jobs and internal services (shipped Feb 2025), closed TCP port monitoring to verify firewall rules, string matching in pulse check bodies, and now a detailed check page with 48h/60d/10y heatmaps and per-month SLA percentages. Geographic coverage expanded with Toronto and Cape Town nodes.

OpenPanel vs updown.io: editorial side-by-side

O
OpenPanel
ANALYTICS
5.0

OpenPanel tags three more note-free builds in one evening, reaching 3.16.4.

◆ Current state

OpenPanel tagged 3.16.2, 3.16.3 and 3.16.4 within about 80 minutes on October 27, after 3.16.1 the day before. Every entry is a build of main for supporters, installed with openpanel upgrade --supporter, and none carries release notes; public releases come from a separate self-hosting tag.

◆ Where it's heading

The 3.x line has climbed from 3.0.0 to 3.16.4 in under two weeks, with each bump published as a bare build. The cadence shows active development, but the feed gives no way to see what changed or which builds matter.

◆ Prediction

Expect more note-free supporter builds; a public self-hosting release with notes is the first point where the content of 3.x becomes visible.

5.0

updown.io adds closed port monitoring and a detailed check metrics page with multi-year uptime heatmaps.

◆ Current state

updown.io has been steadily expanding beyond simple HTTP uptime monitoring: pulse monitoring for cron jobs and internal services (shipped Feb 2025), closed TCP port monitoring to verify firewall rules, string matching in pulse check bodies, and now a detailed check page with 48h/60d/10y heatmaps and per-month SLA percentages. Geographic coverage expanded with Toronto and Cape Town nodes.

◆ Where it's heading

The product is growing from a ping-and-alert tool into a lightweight observability layer for small teams — each release adds a class of monitoring that previously required a heavier tool (Datadog, Grafana). The 10-year performance chart and SLA history are squarely aimed at teams tracking uptime commitments over time, not just incident response.

◆ Prediction

The next likely move is API-accessible historical metrics so teams can pull SLA data into their own reporting — the 10-year chart suggests demand for long-term uptime data that currently lives only in the UI.
