Best on-call tools in 2026

Rotations, escalation policies and paging. These tools decide who is on call now and who is notified next when nobody acknowledges. This list has the top 10 of 30 on-call tools, ranked by a published score. Of these, 1 are open source, 10 have a free plan and 1 can be self-hosted. Checked by hand on 30 September 2026.

How this list is ranked

Each active tool gets a score out of 100. Archived, end-of-sale and maintenance-only tools are left out.

  • Capabilities: up to 75 points for the share of the category checklist that the tool's own documentation confirms. A tool meeting 8 of 10 items gets 60.
  • Free to start: 15 points for a free plan or a free edition.
  • Open or self-hostable: 10 points if it is open source or can be self-hosted.

Each category has a fixed checklist of capabilities (shown in the table below and on every tool page). An item counts only when the tool's own documentation confirms it; anything we could not confirm counts as not met. How long a tool has existed is deliberately not scored, so a new tool is not ranked below an older one for being new. Tools with the same score share a rank (shown as =), are listed A to Z within it, and the list never cuts between them. Nobody pays for a position.
