ThreatCluster
I built ThreatCluster after getting frustrated with how scattered cybersecurity intelligence is. When a major breach or vulnerability hits, you end up reading the same story across 10+ different security blogs, each with slightly different details, but no way to see the complete timeline or understand the full scope. ThreatCluster automatically groups related cybersecurity articles using semantic clustering, so instead of reading fragments, you get one comprehensive view of each threat. It tracks everything from APT campaigns to vulnerability disclosures to ransomware attacks. You can try it…
ThreatCluster launched on January 5, 2026 with 7 votes, #1,609 of 14,584 launches that month and more than 90% of that year's launches.
What it does
ThreatCluster aggregates cybersecurity news from 4000+ sources and clusters related articles together automatically. Instead of reading 10 articles about the same incident, you get one cluster with the full picture. Every cluster includes extracted IOCs, MITRE ATT&CK mappings, threat scoring, and entity tracking for malware, APT groups, CVEs, and more. Free to use. No signup required. Also available as an RSS feed and native MISP feed for direct import into your threat intel platform.
Threat intelligence API for lean security teams: 20,000+ sources deduplicated into scored incident records, first-party dark-web monitoring and validated IOCs. Free API key, no credit card.
Looking for the threat feed? It now lives at threatcluster.io/threats . The only threat intelligence API that puts clustered incident reporting, validated IOCs, vulnerability intelligence and first-party dark-web collection behind one free key. Free key on every account: 100 credits a day, the last 7 days, no card. 70+ endpoints over incidents, IOCs, entities, vulnerabilities, the dark web, and the feeds, alerts and webhooks you run through the API. Pick an endpoint and a language, and see the real response. GET /threats?time_filter=24h curl -H "X-API-Key: $TC_KEY" \ "https://threatcluster.io/api/public/v1/threats?time_filter=24h" import requests r =…from threatcluster.io

Threat RoadNov 2025 · threatroad.substack.com · ▲57Hey HN, I got tired of cybersecurity news reading like a compliance manual written by a sleep-deprived lawyer, so I built Threat Road — a daily, 5-minute, plain-English cybersecurity briefing that’s actually fun. Would love your feedback, especially from people who do IR, AppSec, dev, ops, or just like watching the internet catch fire in slow motion. (And if you hate it, tell me why so I can fix it before it becomes another abandoned Substack graveyard.)
API RadarJan 2026 · apiradar.live · ▲77We built API Radar to track exposed API keys from OpenAI, Claude, Gemini, and other major providers—in real time—from public GitHub repositories. Why? Leaked AI keys are everywhere. They power bots, cost companies thousands, and even expose user data. But no one had a clean dashboard to see the leaks as they happen — until now. What you’ll find: Full redacted + raw API key leaks Real-time feed of exposed repos Leaderboards by author, repo, and provider Filtering by provider (OpenAI, Claude, Gemini, etc.) Timeline of key exposure trends Built for security researchers, devs, and AI companies…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
