uno vs Zap: What are the differences?

What is uno? A uniq like CLI tool for log data. We built uno, a small tool similar to uniq (the UNIX CLI tool that removes duplicates) - but with fuzziness. uno considers two lines to be equal if their edit distance is less than a specified threshold, by default set to 30%. It reads from stdin and prints the deduplicated lines to stdout.

What is Zap? Blazing fast, structured, leveled logging in Go (by Uber). Zap takes a different approach. It includes a reflection-free, zero-allocation JSON encoder, and the base Logger strives to avoid serialization overhead and allocations wherever possible. By building the high-level SugaredLogger on that foundation, zap lets users choose when they need to count every allocation and when they'd prefer a more familiar, loosely typed API.

uno and Zap can be primarily classified as "Logging" tools.

Zap is an open source tool with 7.22K GitHub stars and 553 GitHub forks. Here's a link to Zap's open source repository on GitHub.
