Which to pick
- Pick anyhow if you want the default, widely used error type for applications.
- Pick eyre if you want customizable error reports, especially color-eyre's pretty output with spans and suggestions.
- Bottom line: eyre is a fork of anyhow with pluggable reports; pick it for color-eyre, otherwise anyhow. (checked against each project's docs, Oct 24, 2026)
- Downloads tell you what is common, not what fits. Each crate's own description above says what it is for; when the jobs differ, pick by the job.
- When both fit, prefer the one more crates depend on (anyhow, 52,113 dependents): more eyes, more answered questions, and you may already have it in your tree.
- Check the release dates against your own pace: anyhow 3 months ago, eyre 2 months ago.

Method
Real downloads = the median day with no release that day or the day before, from the crates.io API (Jul 27, 2026 to Oct 23, 2026). Raw crates.io counts include CI and bots and run high (why); the method is from our 90-day study. People search for this pair: Google suggests "anyhow vs eyre".
