I built a CLI tool called LogLens to make querying structured logs (JSON, Logfmt, Nginx) as fast and ergonomic as grep, but with SQL-like capabilities.

To make it easier to try without installing anything, I compiled the core Rust engine to WebAssembly and built a playground.

The Problem: I often found myself needing to filter complex JSON logs over SSH. grep fails at structure ("find errors where latency > 500"), and jq syntax can be hard to type correctly under pressure.

The Solution: LogLens uses a natural query syntax. You can type things like: level is "error" and duration_ms > 500

Key features of the Playground:

    100% Client-Side: Your logs are parsed in memory via WASM. No data is ever sent to a server.

    Structured Parsing: Automatically detects JSON, Logfmt, and common web server formats.

    Range Queries: Just added support for ranges like status between 200..299 or ts between "10m ago".."now".

    Unstructured Search: You can treat logs as raw text too: text contains "timeout".

The core engine is open source (MIT) and written in Rust.

I’d love to hear your feedback on the query syntax and performance!17:T4a4,Yep, that's the title. Stop thinking of AI like an unfair "cheatcode" and start thinking of it as a new programming language. Maybe in other domains, this analogy doesn't match. But that's okay. You're mostly concerned about coding/sysadmin/etc.
