Dozens of AI agents don't just scan — they exploit. They chain attacks (BOLA/IDOR, JWT forgery, mass assignment, SSRF, injection), build and score attack paths, and prove real vulnerabilities at machine speed.

Pentest Swarm AI is an autonomous, open-source API & web-app pentester built on a real swarm. Dozens of AI agents coordinate through a shared stigmergic blackboard to exploit, chain, and prove vulnerabilities at machine speed.

• 🐝 A real swarm, not a pipeline — dozens of agents work your surface concurrently, coordinating via pheromone-weighted findings; attack chains emerge instead of being scripted.
• 💥 Exploits, doesn't just scan — chains BOLA/IDOR, JWT forgery, mass assignment, SSRF, SQLi/NoSQLi, GraphQL abuse — then captures evidence and writes the report.
• 🧠 Any model, self-hosted — Claude, Together AI (GLM/Qwen/DeepSeek), Gemini, OpenAI-compatible, or fully local Ollama / LM Studio. We're the harness that gives models hands.
• ✅ Proof over maybes — non-LLM verification oracles (OOB / differential / timing) confirm findings against the live target; proven ones get a VERIFIED badge.
• 🛡️ Safe by construction — fail-closed scope, egress guard, an authorization gate, and a full audit trail.
• 🎯 Drop-in use cases — bug bounty, external ASM, CI/CD, internal network, CTF, GraphQL, OWASP Top 10 — each a one-command playbook.

⚠️ Authorized use only. This is an autonomous offensive tool that sends real attack traffic to live targets. Use it only against systems you own or have explicit written authorization to test. Unauthorized use is a crime, and you are solely responsible. Scope is enforced fail-closed, and the tool makes you affirm authorization before it attacks a real target.
Read the Responsible Use Policy before you run anything.

XBOW proved a point: AI can top the bug-bounty leaderboards. But XBOW is a closed, hosted SaaS — one agent, on their cloud, on their model, at their price. We think the future of offense is open, self-hosted, and a swarm — so we built it.

Three structural wins — and the swarm is the one that compounds. This isn't a single planner LLM walking recon → classify → exploit → report down a fixed line. Dozens of agents work your surface at once, coordinating through a shared stigmergic blackboard: the instant a finding lands it wakes whichever agent it's relevant to, so a 1,000-subdomain target gets hit in parallel — attacking at machine speed. And unlike a scanner that spits out unverified "maybes," the swarm exploits what it finds, proves it with captured evidence, then writes the report.

Who it's for: pentesters covering a whole scope overnight · bug bounty hunters racing to first-blood on a fresh target · red teamers who need breadth fast · researchers pushing autonomous offense.

Run it on any model — Claude, anything OpenAI-compatible (incl. Together AI's hosted Llama/Qwen/DeepSeek), the new security-tuned open models (Pentest-R1 and the wave behind it), or fully local Ollama / LM Studio. We don't compete with those models — we're the harness that gives them hands: real tools, swarm coordination, scope safety, and evidence-backed reports. Air-gapped, zero API cost, and not one byte of your data leaving your box.

Most "multi-agent" pentesting tools are a single planner LLM dispatching to specialist agents in a fixed order — recon → classify → exploit → report. That's a pipeline, not a swarm.

Pentest Swarm AI is built around three swarm-intelligence primitives:

• Stigmergy — agents coordinate by reading and writing findings on a shared blackboard, not by a central planner telling them what to do. A finding's pheromone weight biases other agents toward it and decays over time, so stale paths die naturally.
• Emergence — attack chains appear that no single agent planned. A recon finding wakes the classifier; a high-severity classification wakes the exploit agent; exploit results feed back into the board and wake the report agent. Order isn't prescribed — it emerges from the blackboard state.
• Decentralization — each agent runs its own trigger predicate. Add a new agent with its own predicate and it joins the swarm without anyone rewriting the orchestrator.

Why it wins: a pipeline is sequential (one stage at a time), can't fold a mid-run discovery back into recon, and is bounded by its slowest stage. A swarm works your surface concurrently, reacts to every new finding, lets attack chains emerge instead of scripting them, and lets stale paths decay and die. The payoff on stage is breadth — a long list of proven findings, because many agents chew on the surface at once.

📖 Full write-up: Architecture — Swarm vs. Pipeline (the blackboard, pheromone decay, emergent chains, and why concurrency stays cheap). Diagrams also live in docs/.

We built this because the category was empty. Every tool marketed as "swarm" was actually a pipeline. If you find a counter-example, open an issue — we'll add them to the comparison table.

One command to install. One command to run. No API key, no cloud, no bill to start.

npm install -g @armurai/pentestswarm                                       # npm (Node ≥16)
curl -fsSL https://raw.githubusercontent.com/Armur-Ai/Pentest-Swarm-AI/main/scripts/install.sh | sh   # any macOS/Linux

docker run --rm ghcr.io/armur-ai/pentestswarm:latest --help                # Docker

pentestswarm run

That's it. run opens the interactive TUI launcher — no flags to memorize:

• Pick your AI provider and paste a key right in the UI — Together AI (hosted Llama / Qwen / DeepSeek), Claude, OpenAI, Gemini, or fully local Ollama / LM Studio (no key at all).
• Point it at a target — a URL, or a bundled vulnerable lab (crAPI, Juice Shop, VAmPI, DVGA) that spins up, gets attacked, and tears down after. Legal, safe, zero setup.
• Choose your live view — a web dashboard on localhost:7777 and a full-screen terminal TUI with live charts, a swarm-topology diagram, and a graded findings stream. Both, by default.
• Then launch and watch the swarm work at machine speed.

A readiness check runs right in the launcher (Go, Docker, tools, provider) — it never blocks; anything missing is shown as a note you can fix or ignore.

run just wraps scan, so everything is scriptable too:

# watch it find a real vuln in ~2 min — bundled lab, local model, no key
pentestswarm scan --lab --lab-target crapi --provider ollama --swarm --tui

# a real target, cloud model for max quality
export PENTESTSWARM_ORCHESTRATOR_API_KEY=your-key-here
pentestswarm scan <authorized-target> --scope <target> --swarm --follow

# prove findings, don't just report them: confirm each high-stakes finding
# against the live target with a non-LLM oracle (OOB / differential / timing)
pentestswarm scan <authorized-target> --scope <target> --swarm --verify

New here? pentestswarm demo plays the whole campaign offline — that's the GIF above. Running inside GitHub Actions? See deploy/github-action/example-workflow.yml.

Each use case is a one-command playbook — a curated swarm configuration for a specific job. List them with pentestswarm playbook list; run one with pentestswarm playbook run <name> --target <t> --scope <scope>.

Full walkthroughs with sample output live in the documentation and the coverage catalog.

Key behaviours:

1. Agents are independent. Any one of them can be removed, replaced, or added without rewiring the others.
2. Pheromones decay per-finding-type. A PORT_OPEN stays hot for hours; a SESSION for minutes. Config-driven half-lives.
3. Scope is enforced at the tool layer and again at the executor. Defence in depth — --scope is not bypassable.
4. Cleanup is always registered before execution. SIGINT, crashes, and budget exhaustion all trigger reverse-order cleanup. See internal/pipeline/cleanup_memory.go and cleanup.go.
5. Prompt caching on Claude cuts cost and latency on repeated system prompts (enabled by default for recon + classifier).

pentestswarm run is the front door — an interactive launcher (provider + key entry, target or bundled lab, live-view choice, readiness checks) so you never have to remember flags. The scan form stays fully scriptable for CI.

All agents inherit from a single provider config. Set one key, the entire swarm works.

See the model comparison and recommendations to choose by quality, cost, privacy, refusal behaviour, and setup effort.

Bring your own model — we're the harness, not the model. A new wave of open models is topping the cyber-offense benchmarks — GLM (5.3), Qwen (3.x), DeepSeek, and security-tuned fine-tunes like Pentest-R1. Pentest Swarm turns any of them — or a frontier model, or a fully-local one — into an operating pentester: real tools, swarm coordination, scope enforcement, and evidence-backed reports. The model does the reasoning; the swarm does the work.

Together AI is first-class — pick together (in pentestswarm run or --provider together) and just add your key; the endpoint is handled for you. Any other OpenAI-API-compatible endpoint (OpenAI, DeepSeek, Groq, …) works via openai + a base-URL, plus first-party Gemini. The only hard requirement is native tool/function calling, which GLM, Qwen, and DeepSeek all support.

Together AI example — run the whole swarm on GLM 5.3:

orchestrator:
  provider: "together"             # first-class — endpoint defaults to Together's API
  model: "zai-org/GLM-5.3"        # or Qwen/..., deepseek-ai/..., etc. — see together.ai/models
  api_key: ""                      # or export PENTESTSWARM_ORCHESTRATOR_API_KEY
  context_window: 128000

• Wave 1 (in flight): real swarm architecture (done), dashboard wire-up, Burp MCP
• Wave 2: sqlmap / Metasploit / ZAP adapters, bug-bounty + ASM + CI/CD playbook polish, official GitHub Action in Marketplace
• Wave 3: fine-tuned Pentest-Swarm model (Pentest-R1 recipe), Cybench / AutoPenBench / CVE-Bench numbers, agent-memory poisoning hardening (MINJA / MemoryGraft defences)

Today the swarm reacts to findings and runs verified attack playbooks (BOLA/IDOR, mass assignment, NoSQL injection, excessive data exposure) end-to-end. Next, we make it think — three major capabilities, each shipping as its own release:

• ① Runtime reaction to discoveries (planned) — stigmergic emergence: the swarm mines every response for object references (ids, UUIDs, emails), writes them to the blackboard, and other agents react by probing those objects across endpoints. Find one leaked id and the swarm turns it into cross-user BOLA/IDOR attacks nobody scripted.
• ② Self-correcting attacks (planned) — closed-loop replanning: a failed step (401/403/415, an odd response body) feeds back into the planner, which adjusts the request and retries. Attacks heal themselves instead of dead-ending.
• ③ On-demand specialist sub-agents (planned) — the swarm spawns purpose-built agents at runtime (an auth agent to hold a session, a fuzzing agent for a discovered parameter, a chain-builder for a specific API) and tears them down when done.

Together these turn a reactive swarm into an adaptive one — attack surface it has never seen, handled without anyone writing a plan. Generalization beyond curated targets and full LLM-driven chaining ride on top of these.

Single agents are tools. Pipelines dressed up as agents are slightly fancier tools. A swarm is different: agents share an environment, each agent's writes influence other agents' behaviour, and the useful work is emergent rather than prescribed. That's what lets a swarm handle a 1,000-subdomain target without anyone writing a plan for it.

One agent is a tool. A swarm is a platform.

Offense is going autonomous — the defense of it should be open. XBOW proved AI can top the bug-bounty leaderboards; it did so as a closed, hosted SaaS. We believe the capability to find and prove vulnerabilities at machine speed shouldn't be locked behind one vendor's cloud and price — it should be open-source, self-hosted, and inspectable, so defenders, researchers, and independent testers can run it on their own infrastructure and their own models.

So our mission is to build the first real open-source pentest swarm in the open: a harness that turns any model — frontier or fully-local — into an operating pentester, with the safety rails (fail-closed scope, egress guard, an authorization gate, a full audit trail) that keep autonomous offense accountable. Powerful real-world-harm capabilities stay gated behind verified, contracted operators — on purpose.

Pentest Swarm AI is free and open source (AGPL-3.0), and always will be. The open-source edition is a fully capable, defensive-grade autonomous API/web-app pentester — it exploits and chains attacks (BOLA/IDOR, JWT, SSRF, SQLi, GraphQL, BFLA…), builds and scores attack paths, ships a large library of attack-path + CVE chains, and includes every safety guardrail (fail-closed scope, egress guard, the authorization gate, and a full audit trail).

More aggressive offensive capabilities are deliberately not in the open-source tool. Post-exploitation and host takeover, credential testing at scale, red-team detection-evasion tradecraft, and similar high-impact capabilities are reserved for the Commercial and Enterprise tiers — and are gated behind identity verification and a signed authorized-use agreement. This is intentional, not a paywall trick: capabilities that are trivially abused for real-world harm should not be handed to anonymous users. Access requires completing verification so there is an accountable, contracted operator behind every powerful action.

Want Commercial or Enterprise access? It requires identity verification and a signed authorized-use agreement — a deliberate safety gate so powerful offensive capability only reaches accountable, authorized operators. Reach out and we'll walk you through verification.
