Open-source kits

Free to run with your own model keys. Ordered by GitHub stars on the check date. A kit attacks whatever endpoint you point it at: a hosted model API, your own app, or an agent.

Promptfoo alternatives

Promptfoo is the most-starred kit here (26,956 stars) and, since March 2026, part of OpenAI. Its MIT-licensed code is still open, so nothing forces a move. If you want a kit outside OpenAI’s ownership anyway, the closest open-source matches are:

  • iFixAi (iFixAi , Apache-2.0): Auditing tool that places an AI agent in a simulated business, sends it everyday and out-of-role requests, and has a judge model from a different provider grade each reply across up to 61 inspections (tool permissions, privilege escalation, prompt injection, cross-user data leaks, destructive actions and more).
  • garak (NVIDIA project , Apache-2.0): Command-line scanner that sends batteries of probes (jailbreaks, prompt injection, data leakage, toxicity, hallucination and more) to an LLM or LLM-backed system and uses detectors to flag failing responses.
  • A.I.G (AI-Infra-Guard) (Tencent , Apache-2.0): Self-hosted AI red-teaming platform from Tencent Zhuque Lab with five scanners: AI infrastructure fingerprint/CVE scanning, LLM jailbreak evaluation, MCP server scanning, agent skill auditing and live agent testing.
  • Giskard (open source) (Giskard , Apache-2.0): Python library for testing AI agents; its giskard-scan package generates adversarial test suites from a plain-language description of your agent and probes it for prompt injection, jailbreaks, harmful content and other vulnerabilities.
  • PyRIT (Microsoft , MIT): Python toolkit from Microsoft's AI Red Team for finding security and safety weaknesses in generative AI systems, with a command-line scanner, a browser GUI (CoPyRIT) and a framework for building multi-turn attack workflows.
  • DeepTeam (Confident AI , Apache-2.0): Python framework that generates single- and multi-turn adversarial attacks against an LLM system you wrap in a callback, then scores 50+ vulnerability types (PII and prompt leakage, bias, BOLA/BFLA, SQL and shell injection, agent goal hijacking and more) with LLM-as-a-judge metrics.

Questions

What is AI red teaming?

Attacking an AI system the way an adversary would, to find where it breaks: prompt injection, jailbreaks, leaking its system prompt or other users’ data, or being talked into misusing the tools an agent can call. The tools here automate it by generating and scoring thousands of adversarial prompts against your model, app or agent.

Is AI red teaming the same as a penetration test of an LLM app?

It overlaps. Red-teaming tools test the model and its prompts and tools. A penetration test of the application also covers the login, access control and APIs around the model, where conventional tools and testers are still needed. Many teams run both.

Which AI red-teaming tools are free?

All 13 open-source kits here are free to run; you pay for the model calls they make. 9 of the 22 commercial platforms state a free tier, trial or free assessment.

Is promptfoo still open source after OpenAI bought it?

Yes, as of November 8, 2026: OpenAI announced the acquisition on 9 March 2026, and Promptfoo’s README says it remains open source and MIT licensed, which the GitHub licence still shows. Its Enterprise and On-Premise tiers are still sold at custom prices.

Can these tools test AI agents and MCP servers?

31 of the 35 tools say they test AI agents, and 13 name MCP servers. Agent testing usually means checking whether the agent can be talked into calling a tool it shouldn’t, with data it shouldn’t share.
