14 open-source tools. All free, all verified live today — 
stars and last-commit dates included so you can see what’s actually maintained.
Only want one? → Maigret for OSINT · Hackingtool for pentesting · Uptime Kuma for monitoring. The rest are situational.
Username → every account they own
These 4 overlap heavily. Start with Maigret; reach for the others only when it misses.
Maigret · 37.1k · Aug 2026 — the default. 3,000+ sites incl. .onion. Doesn’t just check existence — parses bios, photos, links, then recursively hunts the new usernames it finds. HTML/PDF reports, no API keys.
GoSearch · 3.6k · Aug 2026 — 300+ sites, Go-fast, fewer false positives. Its edge: also checks breach dumps — HudsonRock, ProxyNova (3.2B), BreachDirectory (18B).
Blackbird · 7.9k · Jul 2025 — 600+ platforms, AI risk-scores each hit, bulk input from file, PDF/CSV out.
Helix · 25 · Jun 2026 — zero false positives by design: validates through real APIs (Reddit, GitHub, Bluesky) instead of trusting a 200. Handles Cloudflare/WAF, outputs a D3.js connection graph. --permutations tests name variants.
AI does the investigating
Robin · 6.6k · Aug 2026 — dark-web OSINT. LLM refines your queries, filters results, writes the summary.
OpenOSINT · 1.5k · Aug 2026 — terminal agent that picks its own tools and order. Feed it an email/domain/IP/phone → structured Markdown report. 10 modules, HIBP + EXIF + dorks + WHOIS built in. Runs fully offline on Ollama.
DeepDive · 17 · Apr 2026 — builds a 3D entity graph (people/companies/money/places) and keeps expanding it. Timeline + Sankey money-flow views, exports to Obsidian. Ask it “who else got paid by this company?”
Whole arsenals, one command
Hackingtool · 79.2k · Aug 2026 — 185+ security tools, 20 categories, one menu. Shows what’s installed, installs from the menu, auto-detects your package manager. Describe a task (“scan a network”) and it suggests the tool.
Awesome OSINT Arsenal · 2.6k · Aug 2026 — 100+ tools across SOCMINT, GEOINT, dark web, forensics. One-command installer for the lot.
Set up / clean up your machine
Linutil · 5.2k · Aug 2026 — Chris Titus’ Rust TUI. Fresh-Linux setup without Googling commands: apps, dev env, gaming/server tuning. Works across Ubuntu/Arch/Fedora, picks the right command per distro. TOML config automates a full rebuild.
Bloatynosy · 5.6k · Jan 2025 — one-click Windows debloat. Strips UWP junk (Xbox, Candy Crush…), kills telemetry, ad IDs, Cortana, cloud clipboard — no registry or PowerShell.
Monitoring
Uptime Kuma · 90.7k · Aug 2026 — self-hosted uptime for HTTP/TCP/Ping/DNS. 80+ notify integrations, public status page, one Docker command. Runs on a Pi.
Downloader
youtube-dl-wpf · 1.4k · Aug 2026 — clean Windows GUI over yt-dlp. Clips → full movies, playlists, podcasts. Pick quality/format, batch in parallel. No ads, no signup.
Anti-detect browser
CloakBrowser · 30.9k · Aug 2026 — Chromium with 49 patches in the C++ source, not JS injections. Masks canvas, WebGL, audio, fonts, GPU, WebRTC, timing. Drop-in for Playwright/Puppeteer, humanize=True for natural input. MIT.
Their “30/30 detection tests passed” and “reCAPTCHA v3 scores 0.9” are the project’s own claims — unverified by anyone else.
