What it does
A fast, open-source, code analysis tool that excels at expressing code standards — without complicated queries. Rules look just like code; no more wrestling with regexes. Includes 900+ rules and SaaS infra for use in your editor, at commit-time, or in CI.
An extensible developer-friendly application security platform that scans source code to surface true and actionable security issues with AI-assisted SAST, SCA, and Secrets Detection solutions.

https://semgrep.dev/products/semgrep-app Hi! I work on Semgrep, an open-source project (discussed on HN previously [0][1)]. We’re one of those companies that maintain an OSS tool and a web app, and then monetize by selling enterprise features on said web app. Our free web app just went through a major revamp (sort of like a v1.0 release) so this feels like the perfect time to share and hear what the HN crowd thinks! Let me start with some backstory on Semgrep. Our team, r2c, has been experimenting with various ways to help organizations step up their application security…

I built a PR listener and ruleset to detect malicious code in CI/CD2025 · github.com · ▲13I built a GitHub app that detects it in pull requests, notifies or blocks them. Alongside it, I published a Semgrep ruleset for any stage of the CI/CD. I started this after getting frustrated by all the FUD around malicious code - lots of noise, little effort to solve it. Having said that, it's still a major attack vector - a stored RCE, with the codebase itself as the sink. Feedback is appreciated. The app, PRevent - https://github.com/apiiro/PRevent The ruleset: https://github.com/apiiro/malicious-code-ruleset The research:…

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…
