24 alternatives to LiteParse v2, now in Rust 100x faster

LiteParse is an open-source (Apache 2.0) document parser that provides high-quality spatial text parsing with bounding boxes. It does not depend on local or frontier VLMs. Because it does not require GPUs, liteparse can be run on any machine, and process a few hundred pages of documents in seconds. It offers higher accuracy than similar tools like PyPDF, PyMuPDF, MarkItDown. It supports a variety of file formats - PDFs, Office documents, images. It can be one-line installed as a skill for 40+ different AI agents, including Claude Code, Cursor, OpenClaw, Windsurf, and more.

LiteParse v2 is a parsing tool rewritten in Rust for improved performance. It is designed for developers who need efficient code parsing and analysis. The software is available on GitHub. This version emphasizes speed… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Local Document Parsing for Agents▲20
The core processing engine behind LlamaParse is now open source. LiteParse runs entirely locally, has zero Python dependencies, and is built around how agents actually iterate on documents: parse text fast, fall back to screenshots when you need visual reasoning.

Open-source Rule-based PDF parser for RAG▲293
The PDF parser is a rule based parser which uses text co-ordinates (boundary box), graphics and font data. The PDF parser works off text layer and also offers a OCR option to automatically use OCR if there are scanned pages in your PDFs. The OCR feature is based off a modified version of tika which uses tesseract underneath. The PDF Parser offers the following features: * Sections and subsections along with their levels. * Paragraphs - combines lines. * Links between sections and paragraphs. * Tables along with the section the tables are found in. * Lists and nested lists. * Join content…

Parqeye – A CLI tool to visualize and inspect Parquet files▲167
I built a Rust-based CLI/terminal UI for inspecting Parquet files—data, metadata, and row-group-level structure—right from the terminal. If someone sent me a Parquet file, I used to open DuckDB or Polars just to see what was inside. Now I can do it with one command. Repo: https://github.com/kaushiksrini/parqeye

Spart – A Rust library for fast spatial search with Python bindings▲31
Hi everyone, I've made an open-source library for fast spatial search in Rust. It's called Spart, and it currently provides the following features: - Five tree implementations: Quadtree, Octree, Kd-tree, R-tree, and R*-tree - Python bindings (`pyspart` on PyPI) - Fast k-nearest neighbor (kNN) and radius search - Bulk data loading for efficient tree construction Project's GitHub repo: https://github.com/habedi/spart

I rebuilt the only parts of my IDE I use, in Rust, over a weekend▲50
I don't know Rust. Friday after work I realised that 90% of my IDE time now is just the commit/diff view — and even good IDEs feel heavy for that. So over the weekend I built a dedicated native tool for just that. Kyde is a macOS git commit + diff editor with one goal: be fast, do Git well. I'm curious whether anyone else mostly opens their IDE for git operations these days. It's open source, and there's a signed app in Releases.

Hi! I just made an obsdian alternative in terminal after searching for an Obsidian like TUI and got nothing. The closest I found was Glow, but it's only a markdown reader. I wanted something more powerful for the terminal, so I built one myself.

Rust/WASM lighting data toolkit – parses legacy formats, generates SVGs▲52
Hi HN, I'm Holger, a developer who worked in the lighting industry. I built this to scratch my own itch and put it on crates.io and PyPI where nothing like it existed. The old file formats (EULUMDAT from 1990, IES from 1991) still work fine for basic photometry. But the industry is moving toward spectral data – full wavelength distributions instead of just lumen values. The new standards (TM-33, ATLA-S001) are barely supported by existing tools. So this handles both: legacy formats for compatibility, spectral data for anyone who wants to work with the new standards. Stack: Rust core, then…
