24 alternatives to Semgrep App
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…
Semgrep App is a web platform for static analysis and application security testing built around the open-source Semgrep tool. It helps development teams find and fix bugs and security vulnerabilities in their code… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Semgrep App launched in 2021; newer entries below may have overtaken it.

Retool▲640Hi all, founder @ Retool here. We initially launched Retool on HN five years ago: https://news.ycombinator.com/item?id=14515494. The feedback was extraordinarily helpful then (e.g. we launched source control, on-prem, etc. based on HN comments), and we’re grateful for all of it. Today, we’re excited to get HN’s thoughts on one of our new products: Retool Mobile. It lets you build and deploy mobile apps in minutes, not days. The idea is there is a large class of line-of-business mobile apps, and the process of getting a simple form + button on a mobile device, in a native app,…

Yes, it's open source: https://github.com/lissy93/web-check :) Why I'm building this? There are a lot of tools out there for discovering meta and security data relating to a website, IP or server. But currently, there isn't anything that does everything, all in one place and without a paywall/ user sign up. It's still a WIP, and I'm working on a new version, with some more comprehensive checks, so any feedback would be much appreciated :)

ServBay▲399Hello HN, I’m one of the creators of ServBay. I built this because I got tired of the cognitive load required just to start coding. On my Mac, it was a fragile mix of Homebrew services and asdf conflicts. On Windows, managing PATH variables and fighting with Docker Desktop's resource usage was equally frustrating. I missed the simplicity of the MAMP/XAMPP era, but I needed to support modern stacks (Go, Rust, Node, etc.). What it is: ServBay is a native local development environment for both macOS and Windows. It is not a wrapper around Docker or VMs. It bundles everything you need into…

A year ago, my co-founder launched Desktop Docs here on HN. It's a Mac app we built with Electron that uses CLIP embeddings to search photos and videos locally with natural language. We got positive feedback from HN and our first paying customers, but the app was almost 1GB and clunky to use. TLDR; rebuilding in Rust was the right move. So we rewrote the app with Rust and Tauri and here are the results: - App size is 83% smaller: 1GB → 172MB - DMG Installer is 70% smaller: 232MB → 69.5MB - Indexing files is faster: A 38-minute video now indexes in ~3 minutes instead of 10-14 minutes -…

Hey HN! I'm the developer of one of the most popular Android clients for HN, Harmonic for Hacker News. Over the years I have recieved many requests to open source the app which I am finally doing - sorry about taking so long :) Having been very busy working on my PhD during the last two years - Harmonic has not recieved the attention it deserves. I therefore hope that open sourcing it can give it a new lease on life. I also hope that by posting here many of the nice people who have reached out to me will notice that the app is finally open source. I'm also happy to answer questions about the…

In the expanding world of AI my heart still lies in AST transforms, browser fingerprinting, and anti-bot circumvention. But my workflow felt... primitive.

Hey HNs: This is Vincent from the ILLA team. I'm sure you guys see tons of "Open-source" and "Alternative to Retool" these days. I won't deny Retool is a great product, and so are many open-source competitors such as Appsmith, Budibase, Tooljet etc. However, what makes ILLA so special? What advantages does ILLA have that allow users to choose ILLA instead of others? Well, I would like to answer those questions to all folks at HN one by one. First, we are similar to Retool, or Appsmith but we have many different our own features. We are a true open-source project all the folks here can check…

Hey HN! We built a browser-based agent that runs inside an authenticated web app, watches how the app calls its own APIs, and automatically turns those into agent tools. You can think of it as an auto-generated MCP server that self-updates as the host app changes. The result is a skilled AI assistant that actually integrates deeply with any product (not just chat and RAG) with minimal effort. Check out these short demos below that show the agent in software you're probably familiar with: - Jira: https://demo.frigade.com/hn?skill=jira - Spotify:…

Thank you for your comments, just some context: - The app is available for iOS, Android, Windows, Mac, Apple Vision Pro, and the Web. - The Web version is implemented as a Progressive Web Application that is very responsive, local first, offline first, can be installed, and is entirely free to use. - Native (hybrid) versions do not require subscription fees and have small one-time payment. - You can store your notes in Git using any Git provider such as GitHub, GitLab, or Bitbucket. However, it has the best built-in integration with GitHub. Self-hosted scenarios like Gitea are also…

I 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:…

We at Emerge Tools (YC W21) recently released open source Hacker News apps for both iOS and Android. The apps use the latest SwiftUI and Compose frameworks and are entirely native. Our goal is to help dogfood our products, but more importantly our team just enjoys reading HN every day and wanted an app to hack on and call our own. :) We are still missing some features but should otherwise be pretty solid. And open to any contributions. iOS: https://apps.apple.com/us/app/hacker-news-by-emerge/id674092... Android:…

We’re building Refind, a community of founders, hackers, and designers who collect and share the best links on the web. It’s super early but we’re on Product Hunt today and we don’t want to miss the opportunity to reach out to HN too! Founders, hackers, and designers are the audience we had in mind when building this so we’d really love to know what you think! https://refind.com HOW IT WORKS Save great links that will come in handy in the future. Discover what others save. And then find everything again when you really need it – for example when you later search for this topic on…

Yesterday I decided I wanted to experiment with different ways of reading HN. After considering a few options, I settled on a Mac app and spent a couple of hours planning/sketching on paper. This morning I fired up Xcode and spent 4 hours hacking away and I must say I'm liking how it's looking. Since the project is in its very early stages, I though that it could be a very good time to get some feedback. I've posted a few screenshots at http://imgur.com/a/rCbVN and uploaded a binary at http://abra.rm-fr.net/~fiam/HackerNews.zip If you have some free time, give a try and let me know what you…

Tl;DR Save 60% of development effort building your SaaS and enterprise apps using our open-source platform, demo: https://www.youtube.com/watch?v=gob4j072Isg Hi friends, It's a bit surreal writing a Show HN post, being a HN member since 2012, but I'm still excited to be here. We are Arek and Michal (hn: mgl), and we have published Openkoda - an open-source low-code platform for the rapid development of SaaS and enterprise applications. OUR STORY We met at the university and spent the next 10 years building high-performance applications for finance, eCommerce and travel…

Heya HN, excited to show off what I've been privately calling an AI cybersecurity tool built by AI skeptics. Two years ago we started a series of experiments with this philosophy of identifying small pieces of cognitive work where a human can very clearly map out the input data they need and the algorithm they'd follow to make a decision. This idea came partly out of frustration with the zeitgeist involving throwing broad AI features (e.g. useless chat bots) into products that end up unreliable and are targeting no clear problem a user might actually have. It feels kind of like a machete vs.…

There are many like it but this one is mine: https://itunes.apple.com/us/app/pivit/id705715915?mt=8 Seriously, though, this Hacker News reader is better than what's out there, or I wouldn't have spent time on it. How? Most importantly, it utilizes the background refresh APIs, so content is always up to date. Pull to refresh is there, but you probably won't need it. The more addicted you are, the more often it updates. So if you check every few hours, you'll always get the current front page. Complementing this, it helps you see not only what you've read but what…

Hi HN! We kept seeing devs get pwned through MCP tools in ways that security scanners completely miss. So we built an open-source analyzer to catch these attacks. Our first OSS by Mighty team. The problem: At Defcon, we saw MCP exploits with 100% success rate against Claude and Llama. Three attack patterns: Hidden Unicode in "error messages" - Paste a colleague's error into Claude, your SSH keys get exfiltrated Trusted tool updates - That database tool you've used for months? Last week's update added credential theft Tool redefinition - Malicious tool redefines "deploy to prod" to run…
