I’ve been building PRISM - a self-hosted OSINT toolkit you run yourself instead of pasting investigation targets into someone else’s web service.
Give it a domain, IP, email, phone, or username and it runs 22+ modules in parallel into one dashboard: WHOIS, DNS, crt.sh subdomains, GeoIP, threat intel (Shodan/VirusTotal/AbuseIPDB/Censys), breach data, username search across 3000+ sites (Blackbird + Maigret), dark-web mirror checks, and more. Results come with an entity graph, a GeoIP map, an OPSEC exposure score (0–100), and HTML/PDF/CSV/Markdown exports.
Your targets never leave your PC, and 14 of the 22 modules work with zero API keys (missing keys degrade gracefully instead of erroring).
Stack: FastAPI + Next.js 14, runs with one docker compose up. MIT licensed.
Demo: https://getprism.su/ Github: https://github.com/NovaCode37/Prism-platform
Built it solo - feedback welcome, especially on which modules you’d want added.


Some mailchecks would be useful. DNS and the server responses.
Edit: Oops, just found it, different section. Valid DKIM check would be handy. Also, I’m not sure what “Deliverable” is about, comes up as “No” for a domain I use for email with no issues.
Thanks, gotcha. I figured marking those cases as inconclusive makes a lot more sense than treating them as failures. It should cut down on false alarms from catch-all and greylisted servers while still keeping the results reliable. Since I’m already checking MX, SPF, and DMARC, I should have enough confidence without being overly aggressive
