Free via `cargo install --git` or Linux/macOS release binaries. Stream-friendly (`tail -f` works); filter/score/classify modes; ~1.3 GB model cached under XDG. Verified live README + MIT LICENSE 2026-09-26.","theCatch":"Not a drop-in ripgrep — ~10 lines/sec on a laptop CPU and modest zero-shot accuracy; author says check on your data. Early Show HN: ★1 on GitHub. First-run 1.3 GB model download is a disk/bandwidth hit.","verdict":"MIT semantic line filter when grep-by-meaning on CPU beats shipping logs to an API — expect modest accuracy and early-project risk, not ripgrep speed.","addedAt":"2026-09-26","featured":false,"domain":"Libraries","subSpecialty":"Libraries","subcategory":"CLI Utilities","tags":["api","self-host","permissive","active","young-repo"],"capabilities":["api"],"surfaces":["API","Self-host"],"ecosystem":["Node.js"],"licenseModel":"Apache-2.0","githubStars":14,"starsPerWeek":4,"access":"free","archived":false,"repo":{"createdAt":"2026-09-26","pushedAt":"2026-09-26","license":"MIT","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"hono","name":"Hono","tagline":"Tiny TypeScript web framework that runs on every runtime"},{"slug":"phaser","name":"Phaser","tagline":"MIT HTML5 2D game framework with scenes, physics, and tilemaps"},{"slug":"pixijs","name":"PixiJS","tagline":"MIT 2D WebGPU/WebGL renderer, not a game engine"},{"slug":"babylonjs","name":"Babylon.js","tagline":"Apache-2.0 3D engine for the web, now on v9"},{"slug":"playcanvas","name":"PlayCanvas","tagline":"MIT WebGL2/WebGPU engine plus an optional hosted Editor"}],"links":{"self":"/api/gems/gutcheck","html":"/gems/gutcheck","markdown":"/gems/gutcheck.md","category":"/api/gems?category=libraries","categoryPage":"/stacks/libraries"}}
