I built a real-time OSINT dashboard pulling 15 live global feeds
Sup HN, So I got tired of bouncing between Flightradar, MarineTraffic, and Twitter every time something kicked off globally, so I wrote a dashboard to aggregate it all locally. It’s called Shadowbroker. I’ll admit I leaned way too hard into the "movie hacker" aesthetic for the UI, but the actual pipeline underneath is real. It pulls commercial/military ADS-B, the AIS WebSocket stream (about 25,000+ ships), N2YO satellite telemetry, and GDELT conflict data into a single MapLibre instance. Getting this to run without melting my browser was the hardest part. I'm running this on a laptop…
In plain words
Shadowbroker is a real-time open-source intelligence dashboard that aggregates 15 global data feeds into a single map view. It combines aircraft tracking (ADS-B), ship positions (AIS), satellite telemetry, and conflict data from GDELT. Built for analysts and researchers who need simultaneous visibility across multiple global events, the tool runs locally on modest hardware through aggressive data optimization and viewport culling to handle tens of thousands of moving data points without browser crashes.

Sup HN, So I got tired of bouncing between Flightradar, MarineTraffic, and Twitter every time something kicked off globally, so I wrote a dashboard to aggregate it all locally. It’s called Shadowbroker. I’ll admit I leaned way too hard into the "movie hacker" aesthetic for the UI, but the actual pipeline underneath is real. It pulls commercial/military ADS-B, the AIS WebSocket stream (about 25,000+ ships), N2YO satellite telemetry, and GDELT conflict data into a single MapLibre instance. Getting this to run without melting my browser was the hardest part. I'm running this on a laptop with an i5 and an RTX 3050, and initially, dumping 30k+ moving GeoJSON features onto the map just crashed everything. I ended up having to write pretty aggressive viewport culling, debounce the state updates, and compress the FastAPI payloads by like 90% just to make it usable. My favorite part is the signal layer—it actually calculates live GPS jamming zones by aggregating the real-time navigation degradation (NAC-P) of commercial flights overhead. It’s Next.js and Python. I threw a quick-start script in the releases if you just want to spin it up, but the repo is open if you want to dig into the backend. Let me know if my MapLibre implementation is terrible, I'm always looking for ways to optimize the rendering.

Sup HN, So a couple of months ago I posted my OSINT app ShadowBroker here and got WAY more attention than I expected. Some of the feedback was brutal, but honestly, a lot of it was right, and it made the project a lot better. And sure, I had a blast tracking billionaire jets and yachts or discovering GPS jamming in Ukraine was a thrill, and so was watching CCTV feeds from London, along with ships, satellites, conflict zones, etc., but eventually it dawned on me…where does my OSINT dashboard actually go from there? What good is all of the telemetry if people cannot communicate with each other…
- IBI built an OSINT tools directory2025 · r00m101.com · ▲53
I work on R00M 101, a Reddit-based OSINT profiler. While building it, I realized most open-source intelligence (OSINT) tools are scattered across GitHub, outdated blog posts, or random Discords. So I put together a public-facing directory of 100+ OSINT tools used by analysts, journalists, and security folks, free, filterable, and categorized by risk, platform, and use case. The idea was to make something useful and no-friction. Built with static HTML + SQL backend + a lot of caffeine. Would love feedback on how to improve the UX or tool curation. If anyone wants to contribute tools or help…

I made this as a pair programming exercise with o1-preview. o1 did most of the heavy lifting, through high level prompts, but eventually I needed to diverge from it to get to completion. My initial prompt was: --- I'm making a web app: It's like 4chan, but each thread starts with a gps coordinate. People can only post text and images. I want to build it with flask and sqlalchemy. I want just the backend and data model that supports these threads, anonymous users, and users that can register a permanent username. Write as much of it as you can for me. --- This produced a fully scaffolded…
