Lightweight OCR built on PaddleOCR models converted to ONNX, recognizing Chinese and English by default on CPU alone. The rapidocr CLI reads text from screenshots, photos and scanned page images. Needs Python; downloads models on first run, then works offline. Convert PDFs to images first.

Free remote MCP service that turns any GitHub repo or GitHub Pages site into a docs endpoint, so agents can read up-to-date docs and search code on demand and hallucinate fewer APIs. No sign-up or install; self-hosting is also possible.

Needs Git, an authenticated gh CLI and a GitHub repo.

HTTP client CLI that reimplements HTTPie's syntax in Rust with a focus on performance; key-value pairs on the command line are sent as JSON by default, making it quick to debug REST APIs.

From Trail of Bits: reviews PRs, commits or diffs from a security angle, tracing history with git blame, estimating blast radius by caller count and checking test coverage gaps, then writes a Markdown review report.

Query, modify and convert JSON, YAML, TOML, XML, CSV, HCL, INI and more with one selector syntax, editing config files in place or converting between formats, handy for agents handling structured data in scripts. A single dependency-free binary that works much like jq or yq.

Diffusion model inference in pure C/C++: one sd-cli command runs SD, FLUX, Qwen Image, Wan and more locally to create or edit images and short videos, with Metal acceleration on Mac. No cloud needed; bring your own model weights and use a release binary or build from source.
