Best error tracking tools in 2026

Exceptions and crashes grouped into issues, with stack traces and release data, and alerts when a new issue appears or an old one spikes. This list has the top 11 of 22 error tracking tools, ranked by a published score. Of these, 0 are open source, 10 have a free plan and 2 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.
