Gogosseract, a Go Lib for CGo-Free Tesseract OCR via Wazero
Tesseract is one of the largest Open Source OCR (Optical Character Recognition) projects. There is already a Go library for using Tesseract from Go with CGo, called Gosseract. However if you are interested in OCR from Go without C complicating building and cross-compiling, there aren't any other options. Wazero is a Go WASM runtime that doesn't have any CGo dependencies. With Emscripten Tesseract has been compiled to WASM and ran within Wazero. Gogosseract provides a simple API on top of this. This project has been an interesting delve into the world of WASM.
Gogosseract, a Go Lib for CGo-Free Tesseract OCR via Wazero launched on November 4, 2023 with 120 votes, #492 of 4,332 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
Gogosseract is a Go library for optical character recognition that uses Tesseract compiled to WebAssembly, eliminating the need for C dependencies. It runs through Wazero, a Go WebAssembly runtime, making it easier to build and cross-compile OCR functionality in Go applications. The library provides a simplified interface for developers who want to perform text recognition from images without dealing with CGo complications.

LLM-aided OCR – Correcting Tesseract OCR errors with LLMs2024 · github.com · ▲479Almost exactly 1 year ago, I submitted something to HN about using Llama2 (which had just come out) to improve the output of Tesseract OCR by correcting obvious OCR errors [0]. That was exciting at the time because OpenAI's API calls were still quite expensive for GPT4, and the cost of running it on a book-length PDF would just be prohibitive. In contrast, you could run Llama2 locally on a machine with just a CPU, and it would be extremely slow, but "free" if you had a spare machine lying around. Well, it's amazing how things have changed since then. Not only have models gotten a lot better,…

My Go SQLite driver did poorly on a benchmark, so I fixed it2023 · github.com · ▲234https://github.com/ncruces/go-sqlite3 was doing poorly on this benchmark that was posted yesterday to HackerNews [1]. With the help of some pprof, I was able to trace it to a serious performance regression introduced two weeks ago, and come up with the fix (happy to field questions, if you're interested in the nitty gritty). It's not the fastest driver around, but it's no longer the slowest: comfortably middle of the pack. It's based on a WASM build of SQLite, and thanks to https://wazero.io doesn't need CGO. [1]:…
A new stdlib for Golang focusing on platform native support2023 · github.com · ▲154No gc, No goroutines, Produces small binaries while using the unmodified official go toolchain, and comes with complete Web SDK (generated from w3c/webref). We are building `pcz` to provide a reimagination of Go the language, in an effort to make it suitable for all kinds of programming tasks, and currently you can use it to build efficient web applications in Go using the generated Web SDK (as shown with the live web demo[1]). The journey is just starting, any suggestions? or any critics? [1]: https://primecitizens.github.io/livedemos/10-plat-web/
(bits) of a Libc, Optimized for Wasm2025 · github.com · ▲78I make a no-CGO Go SQLite driver, by compiling the amalgamation to Wasm, then loading the result with wazero (a CGO-free Wasm runtime). To compile SQLite, I use wasi-sdk, which uses wasi-libc, which is based on musl. It's been said that musl is slow(er than glibc), which is true, to a point. musl uses SWAR on a size_t to implement various functions in string.h. This is fine, except size_t is just 32-bit on Wasm. I found that implementing a few of those functions with Wasm SIMD128 can make them go around 4x faster. Other functions don't even use SWAR; redoing those can make them 16x faster.…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

SpeedVitals▲829Hi HN, I’m Kashish, one of the co-founders of SpeedVitals, a platform for testing & monitoring website performance with a major emphasis on Core Web Vitals. Until now, our platform has only focused on Synthetic/Lab testing, such as Lighthouse tests and TTFB tests. But now, we have developed a Real-User Monitoring platform that doubles up as a Web Analytics tool. One major feature we have that most RUM tools lack is Performance Audits. Just like Lighthouse audits work on Lab test data, our audits work across all the real-user visits and gives suggestions on what task to prioritize first.…
