Sample issue #002
O11y Watch #002 — UptimeRobot +18%, Lunary ends free signups
Week of 2026-10-24. We re-checked all 73 tracked pricing pages. Every claim links to the vendor's own page.
TL;DR
- UptimeRobot raised paid prices by about 18%. Team is now $46/mo on monthly billing (was $39). The free plan is unchanged.
- Lunary ended free signups. New cloud workspaces require payment and start at $20/user/mo. Existing Free workspaces are grandfathered.
- The directory is now fully reviewed: 70 of 73 vendors verified, plus entry prices, billing model, card and self-host fields.

What it costs you: a team on UptimeRobot Team with annual billing now pays $72 more per year for the same plan.
The take: the free tier is the bait, the second tier is the bill
UptimeRobot didn't touch the free plan. It raised the plan you move to once you need commercial use. The free plan is explicitly for "hobby and non-profit projects." Lunary went further and stopped offering free cloud workspaces to new users. The pattern: free tiers rarely get cut outright; the path off them gets more expensive. When you choose a free tier, price the first paid step too. That's now on every vendor page as "Entry paid price."
Free tier of the week: Uptrace
- Cloud: 50 GB and 5,000 timeseries free per month, then from $0.075/GB
- No seat or host limits: pricing depends only on what you ingest
- No credit card, and the self-hosted Community Edition is free with no limits
- Why it matters: most APM free tiers cap seats. Uptrace caps only data, so a whole team can use it.
- Source: uptrace.dev/pricing
Alternatives if you're affected
- Leaving UptimeRobot (commercial use): Hyperping, free 20 monitors (paid from $24/mo); Instatus, free 15 monitors with 2-min checks
