24 alternatives to Panther v1.0 – Open Source, Cloud-Native SIEM

Hey HN, My name is Jack Naglieri. I’m the founder of Panther Labs - an SF-based cybersecurity startup. Prior to Panther, I was an engineering manager at Airbnb. Before that a security engineer/analyst/forensic analyst. Today, I’m excited to announce Panther v1.0, an open source, cloud-native SIEM: http://github.com/panther-labs/panther Teams can use Panther as an alternative to traditional SIEMs like Splunk. Panther is the culmination of our team’s experience building security tools at scale, including StreamAlert at Airbnb and critical internal monitoring…

Panther is an open-source, cloud-native SIEM that teams can use as an alternative to traditional security information and event management systems like Splunk. The software receives security logs, establishes… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Panther v1.0 – Open Source, Cloud-Native SIEM launched in 2020; newer entries below may have overtaken it.

    Hello Everyone, I'm excited to introduce a new open-source observability platform and would love to hear your feedback. We are aware that there are lots of open-source/commercial tools out there. However, we believe that monitoring the clusters and extracting actionable insights requires deep know-how about the tools/domain. We mainly focused on this problem. - Alaz is an eBPF agent installed on your K8s cluster as DaemonSet. Thanks to eBPF, Alaz collects traces directly from Linux kernels. This means there's no need for sidecars, instrumentations, or service restarts. - The UI not…

    Hello HN! I've been working on Canine for about a year now. It started when I was sick of paying the overhead of using stuff like Heroku, Render, Fly, etc to host some web apps that I've built. At one point I was paying over $400 a month for hosting these in the cloud. Last year I moved all my stuff to Hetzner. For a 4GB machine, the cost of various providers: Heroku = $260 Fly.io = $65 Render = $85 Hetzner = $4 (This problem gets a lot worse when you need > 4GB) The only downside of using Hetzner is that there isn’t a super straightforward way to do stuff like: - DNS management / SSL…

    I've been working on browser automation infrastructure for a while and kept hitting the same ceiling: Playwright and Puppeteer are great for scripting but fall apart when you need stealth at scale. Cloud-based solutions like Browserbase work but you're sending all your data to a third party and can't control the environment. So we built Owl Browser, a self-hosted Chromium-based engine that runs in a single Docker container. The core technical problem we tried to solve was fingerprint consistency. Most browser automation tools either ignore fingerprinting entirely or apply surface-level…

    Hey HN, we're a YC startup building an open-source, privacy-first alternative to Perplexity Comet. No invite system unlike bunch of others – you can download it today from our website or GitHub: https://github.com/browseros-ai/BrowserOS --- Why bother building an alternative? We believe browsers will become the new operating systems, where we offload much bunch of our work to AI agents. But these agents will have access to all your sensitive data – emails, docs, on top of your browser history. Open-source, privacy-first alternatives need to exist. We're not a search or ad…

    Hey, we built an open-source CLI in Go purposed to help you answer security questions across your cloud, code and runtime. It connects to your GitHub, GitLab, AWS, GCP, Azure & K8s using the credentials that are already in your shell, while limiting itself to read-only. The core innovation here is the trust boundary - our agent has a built-in code execution sandbox with no host or network access; it is exposed to an internal tool which we call an “action gate” that performs read-only HTTP requests to your own infrastructure. Since the cloud providers constantly expand actions and services,…

    Hello HN, we're Philip and Louis from Glasskube (https://github.com/glasskube/glasskube). We're working on an open-source package manager for Kubernetes. It's an alternative to tools like Helm or Kustomize, primarily focused on making deploying, updating, and configuring Kubernetes packages simpler and a lot faster. Here is a demo video (https://www.youtube.com/watch?v=aIeTHGWsG2c#t=17s) with quick start instructions. Most developers working with Kubernetes use Helm, an open-source tool created during a hackathon nine years ago. However, with the rapid…

    We’ve been working on Vaev, a minimal web browser engine built from scratch. It supports HTML/XHTML, the CSS cascade, @page rules for pagination, and print-to-PDF rendering. It even handles calc(), var(), and percentage units—and yes, it renders Google.com (mostly). This is an experimental project focused on learning and exploration. Networking is basic (http:// and file:// only), and grid layouts aren’t supported yet, but we’re making progress fast. We’d love your thoughts and feedback.

    Hi Hacker News! Shahar and Tal from Keep here. A few months ago, we introduced here at HN (https://news.ycombinator.com/item?id=34806482) Keep as an “open source alerting CLI” and got some interesting feedback - mainly around UI, automation, and supporting more tools. We were VERY early back then, and we understood that although the current DX around creating alerts is not great, it's not that critical and developers don’t need another tool just for that. But we did find something else. While talking to developers and devops, we found that a lot of companies use many tools…

    Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

    I've built this to make it easy to host your own infra for lightweight VMs at large scale. Intended for exec of AI-generated code, for CICD runners, or for off-chain AI DApps. Mainly to avoid Docker-in-Docker dangers and mess. Super easy to use with CLI / Python SDK, friendly to AI engs who usually don't like to mess with VM orchestration and networking too much. Defense-in-depth philosophy. Would love to get feedback (and contributors: clear & exciting roadmap!), thx

    Hi HN, I’m sharing mochi.js (https://github.com/0xchasercat/mochi), a Bun-native, raw-CDP browser automation framework. It's designed to make programmatic browser use more effective by focusing on consistency and measured parity with regular traffic, purely from the JS layer, against stock Chromium. The most common forms of browser automation focus heavily on client-side line by line probes, which are mostly cosmetic. This makes people feel better but it doesn't have much relevance to actual WAF or anti-automation defences. Mochi.js focuses on what actually matters,…

    Hi HN, We're building Kexa.io (https://github.com/kexa-io/Kexa), an open-source tool developed in France (incubated at Euratech Cyber Campus) to help teams automate the often tedious process of verifying IT security and compliance. Keeping track of configurations across diverse assets (servers, K8s, cloud resources) and ensuring they meet security baselines (like CIS benchmarks, etc.) manually is challenging and error-prone. Our goal with the open-source core is to provide a straightforward way to define checks, scan your assets, and get clear reports on your security…

    I built an open source alternative to wakatime because I don't think a wakatime premium should cost more than a Github copilot subscription. The problem wakatime solves is rather straightforward. Their hardest bit of business is creating all those plugins, besides that the backend just ingests plugin data and organizes it into a dashboard that gives insights into developer work habits. I also felt features like goals, invoices and management of clients shouldn't require premium subscription. And for the most part, I feel I'm right. Especially after implementing these features. The website is…
