In plain words
Opengrep is an open source code analysis engine designed to help developers quickly scan large codebases and identify security vulnerabilities at scale. Created through collaboration among ten security organizations, it aims to make static code security analysis freely available to all users. The tool integrates with GitHub and serves developers who need to detect and fix security issues efficiently without proprietary restrictions.

The fully open source code analysis engine. Quickly analyze large code bases & fix security issues at scale. Initiated by 10 rival security orgs, Opengreps promises to advance and commoditize static code security for the free use of all.
We’re launching Opengrep, a fork of Semgrep CE (formerly Semgrep OSS), in response to recent changes by Semgrep that affect its open-source nature: removing critical features of the scanning engine behind a commercial license - effectively kneecapping its use- and limiting access and progress for the broader community. The key features of the scanning engine removed from the open source engine include language support, tracking ignores, fingerprint, meta-variables, amongst others. Our mission with Opengrep is simple: build the most advanced static analysis engine– fully open-source. We’re investing for the long term with a strong roadmap for impactful new features. We will commoditize and…from opengrep.dev

GritQL, a Rust CLI for rewriting source code2024 · github.com · ▲280Hi everyone! I’m excited to open source GritQL, a Rust CLI for searching and transforming source code. GritQL comes from my experiences with conducting large scale refactors and migrations. Usually, I would start exploring a codebase with grep. This is easy to start with, but most migrations end up accumulating additional requirements like ensuring the right packages are imported and excluding cases which don’t have a viable migration path. Eventually, to build a complex migration, I usually ended up having to write a full codemod program with a tool like jscodeshift. This comes with its own…
Sourcebot, an open-source Sourcegraph alternative2024 · github.com · ▲259Hi HN, We’re Brendan and Michael, the creators of Sourcebot (https://github.com/sourcebot-dev/sourcebot). Sourcebot is an open-source code search tool that allows you to quickly search across many large codebases. Check out our demo video here: https://youtu.be/mrIFYSB_1F4, or try it for yourself on our demo site here: https://demo.sourcebot.dev While at prior roles, we’ve both felt the pain of searching across hundreds of multi-million line codebases. Using local tools like grep were ill-suited since you often only had a handful of codebases…
Open-source security user analytics2024 · github.com · ▲20Our team worked for 1,000 days to create and open-source a web user analytics platform. It is a lightweight (~5 dependencies), “low-tech” PHP/PostgreSQL software that answers the question of what logged-in users are doing on your web application and helps mitigate some risks. Online demo: https://play.tirreno.com Source code: https://github.com/TirrenoTechnologies/tirreno If that's not of interest, there's also a game by @KilledByAPixel: https://play.tirreno.com/game, which has some sentimental flavour. Happy New 20¼ everyone! Dedication:…

Talanoa▲341Hi 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…

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

21st.dev▲1,211I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!
