Eyry builds open-source, agentic recon and offensive security tooling, runs it for you as a hosted platform, and does the hands-on security work when you need a human in the loop.
Need hands-on pentesting or custom tooling? See services.
A product you can run yourself or have us host, and a team you can hire.
Open-source tools for recon and offensive security, free to self-host. Or let Eyry Pro run the whole pipeline for you: always-on monitoring, agent runs, alerting, and teams.
AI-powered pentesting, custom security tooling, and fractional security engineering. The people who build the tools also do the work.
Composable tools for bug bounty hunters, red teamers, and pentesters. Each works on its own; together they watch the surface, dispatch agents, and strike. MIT licensed.
Fast, multi-threaded HTTP prober. The forward scout.
View repo →Producer of new hosts from pluggable feeds (certstream first). The lookout.
View repo →Redis priority queue and work distributor (hot/warm/cold/DLQ).
View repo →Multi-turn agent runtime: compaction, tools, Docker sandbox.
View repo →AI security scanner and reviewer built on Pinnace. The strike.
View repo →Agent control plane: scheduler, events, IRC-style chat, orchestration.
View repo →Eyry Pro is the hosted platform: managed 24/7 attack surface monitoring, agent runs in managed sandboxes, alerting, history, and team features. No infrastructure to stand up.
The open source stays free and uncrippled. Pro sells time, scale, and collaboration.
Early access, launch pricing, and a say in what we build.
Hands-on security from the team building the tools.
Traditional + AI system pentesting using our own tools. Networks, web apps, APIs, and LLM applications.
Custom AI agents and tooling for your security team. Automated scanning, detection, and workflows.
Automate your security workflows with custom solutions. Consulting and implementation.
A part-time security engineer who builds tools and runs pentests. Ongoing partnership.
Transparent starting prices. Engagements scale with scope: pentests $3k–$12k, custom tools $5k–$20k, fractional $5k–$10k/mo. Pentests include a report and a 30-day retest.

Your AI-powered security engineer
Point-in-time recon misses everything that ships after you run it. This is the five-stage pipeline that catches new attack surface the moment it appears, ranks it, and puts eyes on what matters. Self-hostable, with a tool for each stage.
Ends with a recon checklist worth pinning, and the open-source stack to build the whole thing.
